Es war so eine große Idee, es war zudem ein Vorhaben, das wirklich mal den Endkunden, also jeden von uns nutzen bringen sollte, doch das digital – terrestrische Fernsehen scheint schon wieder am Ende zu sein ….

Die Vorstellung, das man theoretisch überall Fernsehen empfangen kann ist wunderbar, und es hat auch nicht lange gedauert, bis viele verschiedene DVB-T Receiver und Antennen zu anständigen Preisen auf dem Markt waren. Und auch die fast flächendeckende Aufschaltung von ARD und ZDF, sowie deren Dritte und Digitalprogramme über DVB-T war relativ zügig abgeschlossen.

Doch dann, dann folgte irgendwie nichts mehr … Die großen (und auch kleineren) Privatsender senden nur in Großstätten digital – terrestrisch. Überall sonst ist nichts von denen zu sehen, und auch kein Vorhaben dieses doch noch zu realisieren zu erkennen. Ganz im Gegenteil. In einigen bayrischen Orten und Kreisen werden sich sogar wieder ein paar Privatsender verabschieden, so zum Beispiel DMAX und Eurosport! RTL sendet zwar bald via DVB-T neben der Region Stuttgart auch in Halle / Leipzig, aber in MPEG 4 und in Conax verschlüsselt. Das heißt, jeder der jetzt schon digital – terrestrisches Fernsehen hat und die RTL – Programme empfangen möchte, braucht wieder einen neuen Receiver!

So wird wohl das Ende von DVB-T beschlossene Sache sein! Denn wenn Jeder gegen Jeden arbeitet und der Zuschauer dabei nur verliert, dann wenden die sich davon ab. Anstatt die Übertragungsart erstmal attraktiv zu machen, veräppeln sie die Verbraucher. Es ist schade, das man so eine wirklich sinnvolle Übertragungstechnik so verkommen lässt!

Maybe we should all step back — well, not me since I haven’t joined the hosanna parade just yet — from lauding Windows 7. I’ve read a multitude of gushing reviews from a variety of sources, but nothing I’ve read has mentioned this little “feature.“

From the link:

Windows 7 beta testers noticed that third-party codecs — video decoders for specific streaming media protocols, such as MPEG-4 — that ran fine under Vista became strangely non-operational under the new OS. It turns out that Windows 7 preempts third-party codecs, favoring codecs built into the OS, and Windows 7 has more built-in codecs than any previous Windows release. Users wanting their favorite third-party codecs to work again must perform some system configuration gymnastics to get them back.

Recently looking for a solution I realized that Video LAN is that powerful for converting Divx to MP4 files. As you may be guessing I wanted to have some of the videos on my iPhone.

Although the websites out there guides you through the required steps to get it done, none of them mention you that Video LAN release 1.0.1 does not support MPEG4-Audio codec. I am not so sure why Video LAN latest release does not provide you this support. In either case the 0.9.9a release does. Download it from the archives and Have fun!

Web-Based Video on Demand Service Based on MPEG-4 Technology

Mpeg-4 is a new multimedia standard for coding and composing audio, video, graphics, text etc., into a presentation scene with user interactivity.Mpeg-4 is an ISO/IEC standard developed by MPEG (Moving Picture Experts Group).

Mpeg-4 is a standard for composing rich media in a graphical scene. Various rich media including audio, video, images, text and graphics can be placed in 2- or 3-dimensional scenes with which user can interact.

I have done the Sample Video using IBM ToolKit in Java.I had designed my Front Page with HTML.The IBM Toolkit for MPEG-4 consists of a set of Java classes and APIs with five sample applications:

• Three cross-platform playback applications and
• Two tools for generating MPEG-4 content for use with MPEG-4-compliant devices.

QuickTime 7 features a state-of-the-art video codec called H.264, which delivers stunning quality at remarkably low data rates. Ratified as part of the MPEG-4 standard (MPEG-4 Part 10), this ultra-efficient technology gives you excellent results across a broad range of bandwidths, from 3G for mobile devices to iChat AV for video conferencing to HD for broadcast and DVD.

Massive Quality, Minimal Files

H.264 uses the latest innovations in video compression technology to provide incredible video quality from the smallest amount of video data. This means you see crisp, clear video in much smaller files, saving you bandwidth and storage costs over previous generations of video codecs. H.264 delivers the same quality as MPEG-2 at a third to half the data rate and up to four times the frame size of MPEG-4 Part 2 at the same data rate. H.264 is truly a sight to behold.

Scalable from 3G to HD and Beyond

H.264 achieves the best-ever compression efficiency for a broad range of applications, such as broadcast, DVD, video conferencing, video-on-demand, streaming and multimedia messaging. And true to its advanced design, H.264 delivers excellent quality across a wide operating range, from 3G to HD and everything in between. Whether you need high-quality video for your mobile phone, iChat, Internet, broadcast or satellite delivery, H.264 provides exceptional performance at impressively low data rates.

The fith part of the case for H.264 by Mark Harraway, UK Country Manager

Q. Has the popularity of M-JPEG caused the CCTV sector to accept low frame rates as the norm? Is there any truth in the adage: “You don’t miss what you’ve never had.”?

I wouldn’t say that M-JPEG is more popular than MPEG4 or H.264. Rather, it’s just that it is an older and easier format and therefore more convenient to adopt.  But then I think the key to this is that when MPEG-4 was introduced, the classic scenario occurred in that those who didn’t offer it tried to frighten the industry by saying that as the B or P frames in MPEG weren’t “complete” frames, this would render the footage inadmissible in court on the grounds that it had been “tampered” with. It’s a similar scenario to so many vendors at this year’s IFSEC saying “Go hybrid!” My contention is that they are only taking this position as they don’t have a comprehensive IP solution and are fudging the issue.

What this has meant is that since M-JPEG makes big demands in both storage and bandwidth, frame rates have been sacrificed meaning that you could miss the crucial shot of a human face. By contrast, with H.264 you can now offer both high frame rate and high resolution very easily over the same bandwidth.  The issue of judicial admissibility of MPEG4 or H.264 has long been solved so I do see H.264 as the future of CCTV in general just as few would argue now that HD is the future of commercial television and movies.

DVB ย่อมาจาก Digital Video Broadcasting
DVB ที่รู้จักกันทั่วไปก็คือ
DVB-C (Cable) คือระบบคเบิ้ล
DVB-S (Satellite) คือระบบดาวเทียม
DVB-T (Terrestrial) คือระบบเสาสัญญาณภาคพื้นดิน
DVB-H (Handheld) คือที่ใช้ตามอุปกรณ์พกพา เห็นได้ใน Nokia N-Series

แต่เรื่องนี้ช่างหัว C,T,H,SH มันไปเถอะ
เราสนใจแต่ระบบ S เท่านั้น!!

DVB-S คือชื่อมาตรฐานข้อทีวีดาวเทียม (Satellite TV)
ตามมาตรฐาน ITU ดาวเทียมจะสื่อสารระหว่างตัวดาวเทียมและสถานีรับด้วยคลื่นเล็กๆ (Microwave) ความถี่ 300Mhz ถึง 300Ghz ใช้การบีบอีดข้อมูลแบบ MPEG-2 ทั้ง Video และ Audio ในประเทศไทยนิยมใช้กัน 2 แบบคือ C-Band และ Ku-Band

ต่างกันคร่าวๆคือ
C-Band จะส่งความถี่ยาว (4-8 Ghz) ให้พื้นที่ครอบคลุมกว้าง สามารถส่งผ่านทะลุเม็ดฝนได้ดี แต่จานรับต้องมีขนาดใหญ่ ขนาด 120cm ขึ้นไป (แต่นิยมเรียกเป็นฟุตซะมากกว่า)
Ku-Band จะส่งความถี่สั้น (12-18 Ghz) ครอบคลุมพื้นที่น้อยกว่า แต่จานรับมีขนาดเล็กกว่า เพราะอัตราความถี่ของข้อมูลที่ส่งมามากกว่า (30-150cm แต่ที่นิยมคือ 35,60,75cm)

ตามสเป็คของตัว USB DVB-S รองรับแบนวิธได้ 1mbit ถึง 45mbit!

อัตราข้อมูลเฉลี่ยของรายการแบบ SDTV อยู่ที่ 1.5~3.6mbit และ 8-9mbit สำหรับ HDTV

ปัจจุบันพัฒนาไปที่ DVB-S2 สิ่งที่เพิ่มขึ้นมาอยากเห็นได้ชัดคือ HDTV และรองรับการส่งข้อมูลแบบ MPEG-4 เพิ่มเข้ามา

แล้วตกลง DVB-S คืออะไร?
- DVB-S ก็คือ ทีวีดาวเทียม ผู้ให้บริการในไทยได้แก่ TrueVisions (จานแดง), UBC (จานเทา) , Samart (จานน้ำเงิน), DTV(จานเหลือง), iPM(จานส้ม), ASTV(จานสนธิ) นั่นเอง

สิ่งที่ทำให้ผู้ให้บริการต่างกันก็คือ “ช่อง” นั่นเอง การจะดู “ช่อง” ต่างๆนั้นจะมีค่าใช้บริการก็คือ สมาชิก ซึ่งมาในรูปแบบของบัตร SmartCard (ต้นทุนเท่า Sim Card)

“ช่อง” เหล่านั้นจะถูกส่งมาด้วยความไม่สมบูรณ์ ซึ่งจะต้องพึ่งพา Key จากบัตรเข้าไปเติมเต็ม ให้สามารถถอดรหัสภาพและเสียงให้ออกมาได้รับชมได้นั่นเอง
…ส่วนเรื่องอื่นเกี่ยวกับบัตร เราไม่นิมยมพูดกันครับ (เพราะเราคนไทย กั๊กไว้หากิน กรั่กๆ)

เอาเป็นว่า TrueVisions เข้ารหัสแบบ IRDETO2 PID 0604, DTV เข้ารหัสแบบ IRDETO2 PID 0614 เอย

คราวหน้าจะโม้ถึงวิธีหันจานหาสัญญาณละกัน
อ้อ..ผมใช้จาน Ku น่ะ

Sony Walkman X1051: Επιστροφή στο σχολείο | koutsou.gR – To kou or to tsou?

Το νέο Sony Walkman X1051 θα μπορούσε να χαρακτηριστεί ως μουσικό φρούριο. Βαρεθήκατε να ακούτε τα τραγούδια σε όποια μορφή και να είναι; Γυρίστε το σε ραδιόφωνο. Έχουν όλα διαφημίσεις; Απλά ενεργοποιήστε το Wifi και ακούστε ιντερνετικούς σταθμούς. Και αυτοί χάλια επιλογές, ε; Ακούστε τις δικές επιλογές από το Slacker (δυστυχώς μη προσβάσιμο από την Ελλάδα).

Πέρα από την μουσική μπορείτε να απολαύσετε και video της μορφής H.264, MPEG-4 και WMV αλλά και να δείτε ότι θέλετε στο Internet. Αν και browser αρχικά τουλάχιστον θα σας δυσκολέψει με τα μικρά του εικονίδια που και λόγο τις οθόνης αφής θα σας δυσκολέψει.[next]

HBO will provide encrypted video content to distribution partners for “TV Everywhere”-style services using Adobe Systems’ Flash multimedia platform, although the premium programmer said it’s amenable to working with other Internet-video technologies.  HBO’s broadband-video complement for TV subscribers, dubbed HBO Go, will use Flash and the Adobe-developed encrypted Real-Time Messaging Protocol, referred to as “RTMPE,” HBO chief technology officer Bob Zitter said in an interview.  “The Flash player is relatively ubiquitous across PCs and Macs,” Zitter said. “It was important to us to make this offering work on Macs as well as PCs.”

Last month HBO said it will participate in Comcast’s 5,000-home nationwide trial of On Demand Online. That will give HBO subscribers in the beta test access to full-length episodes of original series like True Blood, The Wire and The Sopranos, as well as movies including Transformers and The Dark Knight.

In March, HBO and two other Time Warner Inc. companies — Turner Broadcasting System and Warner Bros. Entertainment — announced a strategic alliance with Adobe to develop “next-generation video” across multiple distribution platforms.  Initially the video for HBO Go will be in standard-definition resolution, encoded with the MPEG-4 Advanced Video Coding standard compression format. “HD is something we’re contemplating,” Zitter said.
