<description><![CDATA[With the evolution of Smartphone and exponentially growing market for high speed multimedia services]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p>With the evolution of Smartphone and exponentially growing market for high speed multimedia services the network needs to be smarter for delivering an exhilarating user-experience. .The transformation of mobile devices industry led by advent of successful smartphones such as Blackberry, Apple iPhone the users have become more data hungry and demanding more interactive services loading the mobile network operator&#8217;s network.Multicast and Broadcast services (MBS) is the solution that will not only cater this need efficiently but also attract a large subscriber base. MBS offers real time streaming services, audio-video on demand, multiplayer online gaming, localized services, news advertisements, stocks bringing the most anticipated services at your finger tips.</p>
<p>MBS in 3rd Generation and 4th Generation Wireless systems requires efficient network resource utilization in access and core networks along with scalable and reliable service platforms. Also, it should incorporate the mobility aspects to continuously deliver multimedia information over an efficient air interface.</p>
<p>The major MBS technologies used in various 3G/4G deployment models are Media FLO by Qualcomm, DVB-H (Digital Video Broadcasting-Handheld) by DVB, MBBS by 3GPP and BCMCS by3GPP2. These technologies have garnered much attention for the revenues they can bring to terminal suppliers, network equipment suppliers, mobile operators, broadcast operators, service providers and even governments. </p>
<p><a href="http://technowizz.wordpress.com/files/2009/12/mbs-technologies1.jpg"><img src="http://technowizz.wordpress.com/files/2009/12/mbs-technologies1.jpg?w=1024" alt="Multicast Broadcast Services Technologies" title="MBS technologies" width="442" height="180" class="aligncenter size-large wp-image-104" /></a></p>
<p>The main analysis considering the different old as well as new evolving use cases with the MBS technologies supporting these different services can be mapped as follows: </p>
<p><a href="http://technowizz.wordpress.com/files/2009/12/comparison-with-use-cases1.jpg"><img src="http://technowizz.wordpress.com/files/2009/12/comparison-with-use-cases1.jpg?w=300" alt="" title="Comparison with Use Cases" width="450" height="379" class="aligncenter size-medium wp-image-125" /></a></p>
<p><strong>Considering the above use-cases we can draw insights:</strong></p>
<p>1. <strong>Selection</strong>: The selection of particular MBS technology by the mobile network operator should be based on following criteria </p>
<p><a href="http://technowizz.wordpress.com/files/2009/12/mbs-selection-solution-2.jpg"><img src="http://technowizz.wordpress.com/files/2009/12/mbs-selection-solution-2.jpg?w=300" alt="" title="MBS Selection Solution" width="420" height="168" class="aligncenter size-medium wp-image-123" /></a></p>
<p>2. <strong>Cost:</strong> For heavy duty broadcast applications the resources required would be greater in a 3G network compared to a Broadcast only network such as MediaFLO or DVB-H and hence the cost.<br />
Whereas for light applications and highly interactive applications MBMS or BCMCS would be the ideal choice saving on resources by multicasting to the subscribed group of users instead of broadcasting it to every user in the network. Also, due to availability of an uplink channel, highly interactive applications can be easily supported on the mobile terminal providing a better user experience. Also, from unicasting perspective, with Multicast usage there is a considerable resource savings in core network and radio access network where the radio bearers are lesser than number of users compared to the number of bearers which is equal to number of users in unicast transmissions</p>
<p>3.<strong>Reach</strong>: MediaFLO and DVB-H have a larger cell size and hence a larger footprint which again thus requires lesser base stations covering groups of subscriber services. But again due to the existing vast coverage of the 2G/3G cellular network, these base stations can be easily upgraded  to MBMS/BCMCS capabilities with a comparatively greater reach though smaller individual footprint. </p>
<p>4. <strong>Interactivity</strong>: Broadcast only networks are limited due to the lack of backward channel and hence no interactivity. But the interactivity can be implemented by using network operator’s feedback channel.</p>
<p>5.<strong>Mobile Terminal:</strong>  In the current scenario, for specific applications such as Live TV, broadcast only technologies like MediaFLO or DVB-H might prove to be more efficient but the downfall is the corresponding handsets should be available to receive such broadcasts so that is an additional cost to the MNO’s. </p>
<p>6.<strong>Business Implicaitons</strong>: The broadcast and multicast are complimentary technologies where broadcast can be used for stimulating users to subscribe to the services and multicast services are used to cater specific endusers which eventually subscribes t ospecific services which generate revenues for the operators.</p>
<p>7.<strong>Mobile Trend:</strong>  There is a significant growing trend towards a large number of interactive applications with the advent of modile web due to the availability of smartphones with a larger form factor and advanced capabilities. So most of the NGN will be equipped with cutting edge resource efficient technologies supporting heavy duty streaming and at the same time supporting a higher level of interactivity and a richer user experience with a better continous data connectivity and seamless mobility</p>
<p>Thus with a strong MBS technology selection by the MNO and a lucrative business model a smart telecom value chain is possible and with higher order benefits.</p>

<description><![CDATA[Mobile Entertainment Service Market to Increase threefold to $64bn by 2012 . Music, games and mobile]]></description>
<content:encoded><![CDATA[<div class='snap_preview'><p class="MsoNormal" style="line-height:15.6pt;margin:12pt 0;"><span style="font-family:Arial;" lang="EN"><span style="font-size:small;"><img class="alignleft" src="http://www.mediaflousa.com/content/img/new_corp_images/ourstory.jpg" alt="" width="306" height="294" />Mobile Entertainment Service Market to Increase threefold to $64bn by 2012 . Music, games and mobile TV will be the major contributors to the global mobile entertainment market which will rise   to more than $64 billion by 2012.  Other mobile entertainment sectors include User-generated Content, Gambling, Adult and Infotainment.</span></span></p>
<p class="MsoNormal" style="line-height:15.6pt;margin:12pt 0;"><span style="font-family:Arial;" lang="EN"><span style="font-size:small;"><strong><em><span style="color:#993300;"><a href="http://www.linkedin.com/in/antonishontzeas">By : Antonis Hontzeas M.B.A.</a></span></em></strong></span></span></p>
<p class="MsoNormal" style="line-height:15.6pt;margin:12pt 0;"><span style="font-family:Arial;" lang="EN"><span style="font-size:small;"> Mobile music will remain the largest single sector of the mobile entertainment industry over the next five years. Revenues from music will   to $17.5 billion in 2012, bolstered by the increasing availability of full-track download and streamed services, the former in both paid-for and rental formats.</span></span></p>
<p class="MsoNormal" style="line-height:15.6pt;margin:12pt 0;"><span style="font-family:Arial;" lang="EN"><span style="font-size:small;">Likewise, mobile games will retain its second-ranking in terms of end-user generated revenues: boosted by rapid growth in mass market &#8220;casual&#8221; gaming, revenues are expected to rise   to nearly $16 billion in 2012.</span></span></p>
<p><span style="font-size:small;"><span style="color:black;font-family:Arial;" lang="EN-GB">Among next generation technologies, mobile TV will gain more and more momentum, as mobile users get lots of useful content including information, films and other entertainment related content on their mobiles. Many mobile network operators worldwide have rolled out commercial mobile TV services already, and consumers are becoming more discerning in their demand. The number of mobile TV users in the Asia Pacific region is expected to be around 25 m by the beginning of 2009. While India has already emerged as the fastest growing telecom market in the world,   mobile TV will generate additional revenue stream for service providers and content providers. Though the number of triple-play services users will be less than simple voice and data users, the revenue generated by mobile TV will be very high as mobile TV services will be costlier than the simple services. Various stakeholders, including service providers, content providers, and advertisers benefit from <img class="alignright" src="http://www.3g.co.uk/PR/May2007/ROK.jpg" alt="" width="393" height="297" />service fees, content fees, advertising and paid interactions such as games, videos, and seasonal greetings.</span><span style="font-family:Arial;" lang="EN-GB"> </span><span style="font-family:Arial;" lang="EN">Mobile TV   should see the market rise  to $11.9 billion in 2012</span></span></p>
<p class="MsoNormal" style="line-height:15.6pt;margin:12pt 0;"><span style="font-family:Arial;" lang="EN"><span style="font-size:small;">According to  Dr Windsor Holden, &#8220;With revenues from voice services declining and messaging revenues flat lining, last year finally saw a number of more sophisticated entertainment services begin to fulfill their potential and redress the balance. With more widespread penetration of 3G handsets – or entertainment-focused 2.5G handsets like the iPhone – there is likely to be a much greater surge in both the adoption and overall usage in rich media services.&#8221;</span></span></p>
<p class="MsoNormal" style="line-height:15.6pt;margin:12pt 0;"><span style="font-family:Arial;" lang="EN"><br />
<span style="font-size:small;">Other findings   include:<br />
• Regulations and prohibitions will limit opportunities in the adult and gambling sectors, although   restrictions on gambling services   will ease in the medium term<br />
• China and the Far East will remain the largest regional market for mobile entertainment throughout the period  , with revenues rising   to nearly $21.3bn by 2012<img class="alignright" src="http://www.ecademy.com/images/photo/228964.jpg" alt="" width="226" height="161" /><br />
• Entertainment service adoption remains constrained by difficulties with the user interface, network speed and coverage and the excessive cost of data services</span></span></p>
<p class="MsoNormal" style="line-height:15.6pt;margin:12pt 0;"><span style="font-family:Arial;" lang="EN"><span style="font-size:small;"> </span></span></p>
<p><span style="font-size:small;"><span style="font-family:Arial;" lang="EN">On the other hand, </span><span style="font-family:Arial;" lang="EN-GB">The world’s first Mobile TV, SDMB, was launched in 2004 followed by TDMB in 2005 with the hope of rapid change of user habits to so that broadcasting on a mobile device would become a popular affair.</span></span></p>

<p><span style="font-family:Arial;" lang="EN-GB"><span style="font-size:small;">The initial results in Korea (as they were in Europe in the 2006 – 2007 timeframe) were not very encouraging.</span></span></p>

<p></span></span></p>
<p><span style="font-family:Arial;" lang="EN-GB">In the Korean Case, even though DMB viewers are projected to be more than 30 m by 2012, the related operators are still operating the DMB service at a loss. </span></p>
<p><span style="font-family:Arial;" lang="EN-GB">The unsatisfactory business performance can be traced to :</span></p>
<p><span style="font-family:Arial;" lang="EN-GB"> </span></p>
<p><strong><span style="font-family:Arial;" lang="EN-GB">1. Weak revenue model</span></strong><span style="font-family:Arial;" lang="EN-GB"><br />
TDMB is solely based on Advertising revenue (ie. A clear television business model) but because of the limited viewer base is unattractive as a marketing medium for advertisers.  </span></p>
<p><strong><span style="font-family:Arial;" lang="EN-GB">2. Poor contents</span></strong><span style="font-family:Arial;" lang="EN-GB"><br />
Mobile TV is a personal media, for which viewers watch only in specific situations such as in the subway etc. But the TDMB players are mostly terrestrial broadcasters retransmitting unoriginal or syndicated content. Attempts to produce original material suited or targeted for mobile media failed to produce the required economies of scale which in turn attracted less viewers and entered a negative spiral (<em>or a catch 22</em>).  </span></p>
<p><strong><span style="font-family:Arial;" lang="EN-GB">3. An unbundled bundled mess</span></strong><span style="font-family:Arial;" lang="EN-GB"><br />
Attempts were made to publish bundled services (such as navigation) with the core offering (broadcast content). But inconsistent strategies non coherent diverging strategies by the parties involved resulted in an ineffective incoherent strategy which led nowhere.</span></p>
<p><span style="font-family:Arial;" lang="EN-GB"> </span></p>
<p><strong><span style="text-decoration:underline;"><span style="font-family:Arial;" lang="EN-GB">The European Commission’s approach:</span></span></strong></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">Mobile TV is a new service platform for transmitting audiovisual content – and associated interactive services, in particular in association with 3G services &#8211; to a mobile device. The 2007 Communication indicated the main elements of a European strategy for mobile TV with a view to facilitating the</span></p>
<div id="attachment_2812" class="wp-caption alignright" style="width: 177px"><a href="http://www.box.net/shared/h3rcxppj6z"><img class="size-full wp-image-2812" title="long term evotution ebook" src="http://considerations.wordpress.com/files/2009/01/long-term-evotution-ebook1.jpg" alt="click to download free LTE ebook" width="167" height="163" /></a><p class="wp-caption-text">click to download free LTE ebook</p></div>
<p class="MsoNormal" style="margin:0;"> take-up of these innovative services across the Union. One of the key<a href="http://www.box.net/shared/h3rcxppj6z"></a> elements is the regulatory environment. <strong>Legal certainty </strong>is paramount for operators to take investment decisions, especially with respect to new, innovative technologies such as mobile TV; early investors in particular need to be reassured that they will not be subject to unforeseen constraints at a later stage. <em>Other elements of the EU strategy include the recognition that DVB-H will be the standard for terrestrial mobile TV in Europe</em> (DVB-H was added to the list of official standards of the European Union on 17 March 20083), and the call for frequencies to be granted to mobile TV services in the UHF band, notably on the occasion of the refarming of this band in the context of the digital dividend. On the other hand, interoperability concerns still need to be tackled by industry and the Commission&#8217;s services will monitor developments closely and assess the need for a policy initiative.</p>
<p class="MsoNormal" style="margin:0;"><strong><span style="font-family:Arial;" lang="EN-GB">Mobile TV lies at the heart of convergence</span></strong><span style="font-family:Arial;" lang="EN-GB">. This means that at EU level, mobile TV is subject to two sets of rules, governing transmission and content: the e-communications framework, including aspects related to spectrum policy, and the new Audiovisual Media Services Directive. This Communication addresses authorisation models at national level only with reference to the <strong>e-communications aspects of national regulatory regimes</strong>, and does not touch upon content licences. It summarises the main results of the fact-finding exercise and indicates best practice examples with regard to the main elements of the authorisation regimes for mobile TV. This is intended to serve as a basis for further discussion and exchange of best practice among national authorities.</span></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB"> </span></p>

<p class="MsoNormal" style="margin:0;"><strong><span style="font-family:Arial;" lang="EN-GB">3.4. Specific aspects</span></strong></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">At this early stage of development of the market, it would appear desirable that any specific conditions attached to authorisations are appropriate and avoid imposing unnecessary burdens on operators.</span></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB"> </span></p>
<p class="MsoNormal" style="margin:0;"><em><span style="font-family:Arial;" lang="EN-GB">3.4.1. “Must-carry” rules</span></em></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">In accordance with European legislation, “must-carry” obligations can only be imposed if a significant number of end-users of a network use it as their principal means to receive radio and television broadcasts. At present, mobile TV is still in its start-up phase; “<strong>must-carry”</strong> <strong>rules may not be imposed on mobile TV at this stage</strong>. At any rate, channels benefiting from must-carry are also often “must-have” channels, which actually increase the commercial value for the distribution services and are likely to be included in any main mobile TV bouquet.</span></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">Communication, national regulatory authorities could usefully envisage “must offer” rules for mobile TV as a nascent service needing attractive content.</span></p>
<p class="MsoNormal" style="margin:0;"><strong><span style="font-family:Arial;" lang="EN-GB"> </span></strong></p>
<p class="MsoNormal" style="margin:0;"><em><span style="font-family:Arial;" lang="EN-GB">3.4.2. Network Infrastructure Sharing</span></em></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">Network infrastructure sharing is an important element to minimise roll out costs and increase coverage and transmission capacity. As stated in the 2007 Communication, Member States may consider permitting <strong>network infrastructure sharing</strong> and encouraging co-location when this is needed to facilitate network deployment. Co-location may also be imposed where necessary to address possible environmental concerns.</span></p>
<p class="MsoNormal" style="margin:0;"><strong><span style="font-family:Arial;" lang="EN-GB"> </span></strong></p>
<p class="MsoNormal" style="margin:0;"><em><span style="font-family:Arial;" lang="EN-GB">3.4.3. Interoperability and roaming</span></em></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">The objective of <strong>full interoperability </strong>across networks and devices remains important in order to make possible EU-wide roaming where appropriate, and interoperable solutions should be favoured. Developments in the market have shown that interoperability can be achieved when stakeholders act together with a common aim of implementing a technical standard such as DVB-H. Efforts are currently being made in this respect in industrial and standardisation fora, notably focusing on the services and applications layers.</span></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">Furthermore, the wireless nature of mobile TV means that consumers will legitimately expect devices to work across borders, as is the case with “roaming” mobile telephony. <strong>EU-wide</strong> <strong>mobile TV roaming </strong>is likely to gain importance as the take-up of services grows across Europe. It should also be recalled that some <strong>cross-border or pan-European channels </strong>are already available today and can provide an important test-bed for future pan-European services. The launch of DVB-SH based mobile satellite TV services is expected for next year in Europe.</span></p>

A point-to-multipoint communication can broadcast the same content to a large number of viewers. This is where MBMS or Mobile Broadcast Multicast Service steps in to help the network operators. MBMS is standardized by 3GPP as part of the WCDMA evolution and will be available for both GSM/EDGE and WCDMA connections. In MBMS, with point-to-multipoint (PTM) paradigm, ideal for mobile TV, data packets are simultaneously transmitted from a single source to multiple destinations. Unlike in the unicast paradigm, where data packets are transmitted from a single source to a single person. The MBMS technology allows a group of people interested in a particular program, in a particular area, to watch the same program simultaneously, via both existing GSM as well as UMTS networks. The MBMS technology supports HSPA in a situation where higher loads have to be transmitted in dense areas, saving significant network capacity and enabling a more efficient use of network resources, which ultimately results in cost saving for network operators. MBMS is also included as a supported technology in <strong><em>Long Term Evolution</em></strong>.</span></span><span style="color:black;font-family:Arial;" lang="EN-GB"><span style="font-size:small;">Today, most mobile TV services worldwide are based on two-way point-to-point data transmission using unicast. Once MBMS is introduced commercially, which is expected in this year, the same content can be delivered to a mass number of terminals in a single transmission via multicast. But it doesn&#8217;t mean that the introduction of MBMS will invalidate unicast. While MBMS can be used for the most popular programs for a registered multicast group, unicast can be used to deliver on-demand videos to the same group in a cost-effective way. This unique unicast-MBMS model will help achive personalization as well as delivering content to a mass market.<img class="alignleft size-medium wp-image-2071" title=" " src="http://considerations.wordpress.com/files/2008/12/mbms-architecture.jpg?w=300" alt=" " width="300" height="213" /></span></span></p>

<p><span style="color:black;font-family:Arial;" lang="EN-GB"><span style="font-size:small;">As MBMS requires only minor changes to the existing radio and core network protocols, it reduces the implementation cost of infrastructures like terminals and networks. With its capacity-boosting features, MBMS aims at stimulating the development of new and mobile mass-media services, generating revenue opportunity for network operators and content providers. It will enable service providers to offer cost-effective triple-play services for mobile handheld devices over a common service and network infrastructure.</span></span></p>
<p><span style="color:black;font-family:Arial;" lang="EN-GB"><span style="font-size:small;">Before MBMS is introduced in the market, device manufacturers also have to come up with low-power consuming cell phone batteries, essential to support data intensive applications, and handsets for high memory capacity to support the high buffer requirements of mobile TV.</span></span></td>

<p><strong><em><span style="font-family:Arial;" lang="EN-GB">DVB-H</span></em></strong></p>
<p class="MsoNormal" style="margin:0;"><span style="color:black;font-family:Arial;" lang="EN-GB">When DVB-T was first published in 1997, it wasn’t designed to target mobile receivers. However, following very positive experimental results, DVB-T mobile services were launched in Singapore and Germany, with extensive commercial trials elsewhere. Indeed, with the advent of diversity antenna receivers, services which target fixed reception can now largely be received on the move as well. So why DVB-H? <strong>Battery</strong><strong> life</strong>! Despite the success of mobile DVB-T reception, the major concern with any handheld device is that of battery life. Power consumption of DVB-T front ends is too high to support handheld receivers that are expected to last from one to several days on a single charge. The other major requirements for DVB-H is the ability to receive 15Mbit/s in an 8MHz channel and in a wide area single frequency network (SFN) at high speed. These requirements were drawn up after much debate and with an eye on emerging convergence devices providing video services and other broadcast data services to 2.5G, 3G and future handheld devices. Furthermore, all this should be possible while maintaining <img class="alignright" src="http://amuse.ftw.at/images/live-dvbh-testbed.gif" alt="" width="350" height="270" />maximum compatibility with existing DVB-T networks and systems. </span><strong><span style="color:#7e0c00;font-family:Arial;" lang="EN-GB">  </span></strong><span style="color:black;font-family:Arial;" lang="EN-GB">In order to meet the above requirements, the DVB-H specification includes: <em>Time-Slicing Rather</em> than continuous data transmission as in DVB-T, DVB-H employs a mechanism where bursts of data are received at a time – a so-called IP datacast carousel. This means that the receiver is inactive for much of the time, and can thus, by means of clever control signalling, be &#8220;switched off&#8221;. The result is a power saving of some 90% and more in some cases. </span></p>
<p class="MsoNormal" style="margin:0;"><em><span style="color:black;font-family:Arial;" lang="EN-GB"><img class="alignleft" src="http://www.ubergizmo.com/photos/2008/4/nokia-n92-dvb-h.jpg" alt="" width="468" height="333" />4K-mode</span></em><span style="color:black;font-family:Arial;" lang="EN-GB"> With the addition of a 4K mode with some 3409 active carriers, DVB-H benefits from the compromise between the high-speed small-area SFN capability of 2K DVB-T and the lower speed but larger area SFN of 8K DVB-T. In addition, with the aid of enhanced in-depth interleavers in the 2K and 4K modes, DVB-H has even better immunity to ignition interference.</span></p>
<p class="MsoNormal" style="margin:0;"><span style="color:black;font-family:Arial;" lang="EN-GB">MPE-FEC The addition of an optional, multiplexer level, forward error correction scheme means that DVB-H transmissions can be even more robust. This is advantageous when considering the hostile environments and poor but sexy antenna designs typical of handheld receivers. </span><strong><span style="color:#7e0c00;font-family:Arial;" lang="EN-GB"> </span></strong><span style="color:black;font-family:Arial;" lang="EN-GB">Like DVB-T, DVB-H can be used in 6, 7 and 8 MHz channel environments. However, a 5MHz option is also specified for use in non-broadcast environments. A key initial requirement, and a significant feature of DVB-H, is that it can co-exist with DVB-T in the same multiplex. Thus, an operator can choose to have 2 DVB-T services and one DVB-H service in the same overall DVB-T multiplex. </span><strong><span style="color:#7e0c00;font-family:Arial;" lang="EN-GB"> </span></strong><span style="color:black;font-family:Arial;" lang="EN-GB">     DVB-H today encompasses a powerful tool to address new markets for DVB services.</span></p>
<p><span style="font-family:Arial;" lang="EN-GB"> </span></p>
<p><strong><em><span lang="EN-GB"><span style="font-family:Times New Roman;">WiMax Based</span></span></em></strong></p>
<p><span style="font-family:Times New Roman;"><span lang="EN-GB">The evolution from 3G to 4G (non LTE) is set to be stimulated by services that <img class="alignleft" src="http://aycu01.webshots.com/image/6680/2000100508986807813_rs.jpg" alt="" width="272" height="359" />offer enhanced quality. Quality indicators span increased bandwidth, elevated sophistication in terms of large-scale information provision, and improved customization capabilities. The maturity of key 4G technologies such as OFDMA, MIMO, and optimized MAC scheduling algorithms realize a range of desirable features. These include enhanced handover and mobility, major infrastructure design requirements that promote a rapid response, elevated session rates, increased capacity, reduced user charges, swift return on investment (ROI) for operators, and simplified autonomous terminals. WiMAX, in this context, describes an interesting choice for pre-4G technology. Its rapid time to market provides an ALL IP flat network solution that can complement existing 2G/3G networks so as to deliver mobile TV and video services with a guaranteed Quality of Service (QoS). Based on the mobile access methods mentioned above, there exist a variety of competing technologies that are available for mobile TV service provision. The three main categories cover mobile and broadcast networks and DVB-SH for satellite. The availability of multiple broadcasting technologies offers operators more options to choose from, and vendors richer experiences in mobile TV solutions. Additionally, the competition between different technologies is necessary to promote the development of mobile TV. Given that 3G networks are currently under utilized, some mobile operators are offering streamed TV and video content at highly attractive prices to encourage consumers to adopt and use their services.    WiMAX TDD, which operates under a duplexing mode, is best suited for data applications and advanced antenna technologies. The rapid scheduling of uplinks and downlinks realizes bandwidth requirements for different applications. Flexible and diversified mobile TV and video service business models are facilitated, which results in maximized profit margins for operators.</span><strong><em> </em></strong></span></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">The WiMAX Forum MCBCS sub team has been aggressively pursuing related standard development.   In terms of network deployment, operators are broadly concerned with economic development, rapid ROI coupled with a long-term evolution potential that protects investment, device availability, appropriate pricing, and smooth upgrade capabilities can accommodate nascent applications. WiMAX is based upon a 2-layer ALL IP network architecture and is widely regarded as a cost-effective means to provide VoIP and data services. The WiMAX Forum is committed to enabling MCBCS with minimal changes to existing networks in order to support mobile TV &#38; video. Mobile WiMAX claims a long-term and smooth transition route towards 802.16m, which allows a network to support peak data rates with at least 6.5bps/Hz for downlinks, and 2.8bps/Hz for uplinks. Particularly with 802.16m, a dedicated carrier will be allocated for MCBCS. Optimized switching between broadcast and unicast services can be achieved, and the maximum MCBCS channel reselection interruption time is 1 second for intra frequency and 1.5 seconds for inter frequency.   The above analysis underpins the belief that 3G-based enterprises should boost ARPU by taking advantage of the unused capacity and availability that can be found in multicast broadcast technology. This can fulfill the needs of mobile TV &#38; video service users who form a third of the mobile Internet market. However,   both unicast and multicast based on a non MBMS 3G network may be prohibitive in a mass market context. High levels of investment are necessary for the deployment of proprietary mobile TV technologies based on satellite networks.   Satellite, therefore, is only a temporary or complementary choice to broadcast architectures. WiMAX MCBCS, claims to render multicast cost-competitive with broadcast technology, and it is scalable to serve the mass market. Thus, it forms a long term solution for the mass consumption of mobile TV &#38; video applications.<img class="alignright" src="http://www.udcast.com/images/schemas/udcast_wimax_tv_architecture.jpg" alt="" width="636" height="206" /></span></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB"> On the access network side, there are base stations (BSs) and a gateway. In the core network, a MBS Controller (MBSC) is connected to the content server that can operate under the control of an operator or a third party. AAA is employed to perform authentication and authorization with appropriate user profile information, collect billing information, and then send it to the Business Operation Support System (BOSS).   The two ways to provide mobile TV are through unicast and broadcast, and they differ in three basic aspects: channels (dedicated or common), requirements (individual or general), and tariffs (high or low). Mobile TV services usually embody a basic service need in the form of programs with mass appeal. Examples include live sporting events and real-time news. Payto- view prime time programs target a given user group with specific interests, and these are not necessarily live programs. Therefore, Wimax deployment (as in the case of MBMS) suggests using broadcast for basic services and unicast for targeted services. <strong> </strong></span></p>

<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">From the mobile TV multi media technologies stated above, MBMS seems to be the closest to allowing enhanced user/crowd controlled interaction. Indeed MBMS (if at some point suppliers abandon their walled garden approach and “open” there tcp stack towards other internet applications) is the technology that can most easily be adapted to the prevailing web 2.0 requirements which are : </span></p>

Mobile TV defines one more enabler of digital entertainment. As such, its positioning has to support the control of a strategic business alignment of technologies, markets, and content.</span></p>
<p class="MsoNormal" style="margin:0;"><span style="font-family:Arial;" lang="EN-GB">While DVB-H is a pure broadcast technology, with an established business model and a strong marketing research reference (ie. 50 + years of television) MBMS (and even more so WiMAx mobile tv offerings) is caught in a crossfire. On the one hand MBMS is an interactive technology (like IPTV) but on the other hand, the strategy (position and evolutionary) followed by telecom suppliers (they are after all telecom suppliers) is that of a broadcast technology. The result of this  strategy is that   MBMS ends up as <em>a hotel video on demand service </em>on a handheld when clearly users have indicated other preferences and usage habits for mobile (handheld) multimedia (example : citizen journalism) as opposed to fixed (IPTV) multi media. <em>This may dangerously push MBMS towards oblivion if steps are not take to re-examine, rethink and realign the positioning of this excellent technology</em>.</span></p>

<content:encoded><![CDATA[<div class='snap_preview'><p><a href="http://www.flickr.com/photos/ousby/48716795/" target="_blank"><img class="alignnone size-medium wp-image-35 alignright" style="float:right;" src="http://fatcontroller.wordpress.com/files/2008/05/48716795_d96700f774_b.jpg?w=300" alt="BBC7" width="300" height="225" /></a>I&#8217;ve finally closed down my old blog, but found a post from back in 2006 that i couldn&#8217;t quite bring myself to throw away. It was the time when BT movio launched their DAB-IP  mobile TV service, which closed down a year later due to several reasons: only one handset, one operator supporting it and a lack of demand for mobile TV as a killer reason to buy a, let&#8217;s be honest, ugly handset. The pic here is one of the prototype devices but it wasn&#8217;t that much uglier than the device which was launched, even if Pamela Anderson tried to counteract the fact&#8230; (sorry virgin mobile!). The service was 5 digital TV channels on your phone; and thanks to the DAB technology it was based on, the full selection of DAB digital radio stations in your area (50 in london), with a full 7 day programme guide (EPG) with colour logos and LiveText (the scrolling text you see on normal digital radios).</p>
<p>You may have heard about various other mobile TV services delivered OTA. The limitation of these offerings is the number of people who can simultaneously watch video in a given area. Mobile broadcast TV has no such limitations.</p>
<p>BT Movio ran a trial at the end of 2005 which revealed that, counter to expectations, a significant number of people used the service more often at home than on the move. In addition, they listened to radio services more than viewing TV (95 vs 66 minutes per week respectively), with an average viewing length of 22 minutes for radio vs 16 for TV. The arqiva / o2 trial of DVB-H reported that 70% of triallists expected digital radio as part of a commercial service. The movio trial results were proved accurate once the real service launched (to an admittedly small number of subscribers). I still maintain that this implementation was the best and most intuitive digital radio interface for a mobile device &#8211; a fully functional EPG used for primary navigation rather than a nice to have.</p>
<p>So it looks like digital radio, as well as TV will play a part in emerging mobile services, however the big question is will sufficient numbers of people want to watch TV on their mobile phone? And how many channels will they want access to? The answer so far seems to be that a straightforward port of linear tv to mobile isn&#8217;t quite as sexy as many people hoped.</p>
<p>If we look at the Korean experience, the big audience drivers are pretty much the same as we see in traditional TV – e.g. big sporting events and major breaking news – however, bespoke “made for mobile” channels are becoming more prevalent as the technology gains acceptance. One could also argue that in order to get across a simple compelling message to a new audience you have to go with what is familiar – i.e. watch what you normally watch, but at times and in places more convenient to you, and that bespoke “made for mobile” services will emerge as the market matures. One thing seems to be certain for now, mobile TV isn&#8217;t going to be the main reason people buy a phone for some time to come. Something much simpler, Bluetooth, is one of the most commonly desired features in handsets for the young &#8211; not for the technology but for what it allows &#8211; free transfer of audio, video and images without fear of prosecution&#8230;</p>
<p>From my experience of OTA mobile TV through the operator walled gardens and from my experience of (in)consistent service from my mobile wifi skype phone, I think we are a way off providing a consistent linear service via 3g or mobile internet. It just doesn&#8217;t work if you move around too much. Nomadic rather than truly portable consumption. Of course this will get better, but however much it improves there wil always be a need for a more complete offer.</p>
<p>I also think that we need to think about what really works in a live environment in two respects: Firstly, TV has a much more limited live portfolio than radio, secondly there&#8217;s no reason to separate TV from radio in the same channel, particularly if the radio is visualised (retaining audio primacy &#8211; rich man&#8217;s radio, not poor man&#8217;s TV)</p>
<p>The particular flavour of broadcast linear mobile TV right now seems to be favouring DVB-H in Europe, and DVB-H2 offers some interesting developments, moving ever closer to <a href="http://en.wikipedia.org/wiki/Claude_Shannon" target="_blank">claude shannon&#8217;s</a> theoretical maxima. However as far as digital radio goes, DVB-H and derivatives are based on a different set of standards with accompanying royalties and there would be huge efforts required to get a significant number of devices in the market at vaguely reasonable prices across all the situations in which people listen to radio. a &#8220;simple&#8221; swap over to a new technology for digital radio in all it&#8217;s forms is naive at best. T-DMB at least was a technology that allowed radio to come for free with mobile TV, not so for DVB-H. This is without even considering the complexity of the spectrum required (UHF vs Band III).</p>
<p>It will be interesting to see what happens with data tariffs OTA, and whether linear streaming over IP will be limited by the operators or seen as a way of encouraging use, and if so how soon MBMS will show it&#8217;s limitations &#8211; and let&#8217;s keep a following brief on wimax.</p>
<p>It&#8217;s not too far fetched to think of a mobile service that transparently allows sideloading and downloading of on demand audio and video content, access to broadcast linear mobile tv and/or radio, 3/4g/LTE or wifi/wimax access to niche linear channels and on demand content all through a simple, intuitive ESG that always offers you something you want AND is available regardless of the vagueries of network connectivity.</p>

<content:encoded><![CDATA[<div class='snap_preview'><p>Il mobile sarà la killer application della tv 2.0? Dipende, dalle tecnologie e dai contenuti, certamente. Rispetto alla prima variabile le novità non mancano. La tecnologia MBMS, per esempio, promette di rendere i telefoni 3G in recettori di segnali sia broadcast che multicast sfruttando la rete UMTS esistente; Huawei e Qualcomm in collaborazione con Telecom Italia hanno appena realizzato il primo trial in Europa, affermando di aver raggiunto risultati migliori delle loro stesse previsioni. Più interessante, quantomeno perché già esistente, è <a href="http://www.cellspin.net/">Cellspin</a>, un&#8217;applicazione che permette di pubblicare in maniera istantanea dal proprio cellulare direttamente sulle nostre pagine personali: facebook, flickr, myspace, il nostro blog. Tutto in pochi semplici passi, a dimostrazione del fatto che il social network è la killer application del web e, di conseguenza, di tutti i device in grado di connettersi, come conferma in un&#8217;intervista su <a href="http://www.repubblica.it/supplementi/af/2008/05/05/multimedia/027axante.html">Repubblica Affari e Finanza</a> Mauro Del Rio, presidente di <a href="http://www.buongiorno.com/it/">Buongiorno</a>:&#8221;Google e il web sui nuovi cellulari sono importanti, ma Facebook o MySpace lo sono di più&#8221;.<br />
Secondo un <a href="http://www.marketingcharts.com/interactive/mobile-internet-significantly-extends-reach-of-some-leading-websites-4456/">rapporto</a> di Nielsen, alcuni dei maggiori siti raccolgono già gran parte del loro visite da cellulare, come AccuWeather.com, che riceve il 43% del suo traffico proprio da connessioni mobili. Jeff Herrmann, vice presidente di Mobile Media, Nielsen Mobile, ha commentato:  “The data demonstrate that the mobile internet can not only increase the frequency of visits to a website, but also grow the overall size of the pie [...] Publishers can now monetize their total cross-platform audience, and advertisers will better understand the efficiency and incremental value of mobile web traffic.”</p>

<p>Pare essersene accorta la Associated Press, che ha appena lanciato <a href="http://www.apnews.com/">Mobile News Network</a>, un servizio di news, sport e intrattenimento ottimizzati per iPhone e in grado di distribuire non solo testo e immagini, am anche video.<br />
Vista la relativa novità del settore, la mobile marketing association ha pubblicato <a href="http://www.google.it/url?sa=t&#38;ct=res&#38;cd=1&#38;url=http%3A%2F%2Fwww.mmaglobal.com%2Fmobileadvertising.pdf&#38;ei=XeshSKHjO5SWwAGQ2eXMAw&#38;usg=AFQjCNFU0SOMnxOTN9pmcAruZFXNLIAZyQ&#38;sig2=kQyXc7T8qXDNOrKlMb0E_Q">Mobile Advertising Guidelines</a>, utile strumento per addentrarsi in questo territorio ancora tutto da esplorare. Interessanti anche i dati di eMarketer sugli investimenti nel mobile.</p>
