HDTV tuners are specially planned devices which receive and output HDTV signals. The HDTV (high definition television) is the latest addition in DTV. These transmit programs in a widescreen format with high resolution pictures and surround sounds. Thus, they provide ambience and feel of theaters in homes.

The HDTV tuners are also known as a decoders, receivers, and set-top boxes. A HDTV tuner will receive signal in the form of ATSC formats. The received signals are decoded in HDTV signal before displaying it on your television screen. The picture quality of HDTV will range from 720p to 1080i with a ratio of 16:9. Generally, the HDTV tuners will receive all the HDTV signals including cable, satellite, OTA (over-the-air) broadcasts, and digital- VHS recordings.

Commonly, the HDTV tuners can be availed as an external box or come integrated with HDTV sets or HDTV receivers. The external HDTV tuners are usually connected between the antenna and the television. The television sets or receivers encompassed with HDTV tuners will not require external HDTV tuners to receive standard cable channels. For analog televisions and digital televisions without inbuilt HDTV tuners, the external HDTV tuner is the ideal way to enjoy the benefits of HDTV signals.

HDTV tuners are available in different price levels. On an average, the cost of the HDTV tuner will range from $100 to $400. The price will fluctuate from one brand to another.

Sharp, Panasonic, Mitsubishi, Thomson, and Samsung are some of the leading brands.

HDTV tuners can be availed from local dealers or online stores. An online store is the best source to avail better options in HDTV tuners. crutchfield.com, store.snapstream.com, and digitalconnection.com are some of the leading online stores to shop for HDTV tuners.

To suit different needs, HDTV tuners come combined with exclusive features. These include program guide (EPG) display for each channel, self-guided setup, interactive program guides, and more. The HDTV tuners with hard drives are capable of recording standard digital TV and HDTV programs. With advance features, an HDTV tuner will give you the ambience of a theater at home.

HDTV converters are specially designed devices for signal conversion. HDTV, also known as High Definition Television, is the most recent innovation in DTV. The HDTV can telecast pictures with high resolutions which are twice more than the traditional analog telecasts and surround sound.

Generally, the HDTV converters are incorporated in most of the HDTV systems. But, the HDTV systems are quite expensive. Moreover, today, most of the homes have analog television sets. To enjoy the effect of HDTV, you can implement a HDTV converter in your analog televisions sets. The HDTV converters will transform the digital signals into analog signals. Thus, the converter will help the analog televisions provide the maximum picture quality almost similar to HDTV sets.

To experience, the full benefits of HDTV signals, HDTV systems are always apt because the analog televisions will not be able to display the pictures with high resolution and surround sound as sharp as HDTV sets.

The HDTV converter automatically detects the input signal, which can be in RGBHV, YPbPr, or YCbCr format, and converts the signal into display with 480i, 480p, 720p, or 1080i resolution. Apart from this, the HDTV converters can also take 480i component video signals, and decode into the display with HDTV resolutions, where, “i” means interlaced and “p” means progressive. HDTV converters can transfer numerous pixels on a scan line into analog signals for horizontal resolutions. In the case of vertical resolutions, the HDTV converters will transform the 16:9 ratio HDTV picture with 1080i into a 480 scan line picture with 4:3 ratio or a picture with 360 scan line with 60 line black letterbox bars.

Unlike the ordinary television converters, HDTV converters are highly compact devices embedded with cutting-edge technology. With the increase in the demand, different brands and types of HDTV converters are available in the market. Philips, Viewsonic, Doremi Labs, Inc., JVC Professional Products Company, and Panasonic are some of the leading brands in HDTV converters. Prices of the HDTV converters will range from $150 to $300. HDTV converters can be purchased from local outlets or electronic stores. For better option in prices, brands, and types, online or electronic stores are always ideal.

Se você está pensando em comprar uma televisão nova, tenho certeza que está se perguntando “qual modelo eu devo comprar”. Isso porque comprar uma televisão hoje em dia está tão ou mais difícil do que comprar um computador.

A maioria das dúvidas aparecem quando você começa a tentar imaginar qual a aplicação para a nova televisão, ou seja, se ela ficará no quarto ou na sala, pendurada ou não, se você montará um home-theater com utilização de várias conexões e equipamentos ou apenas para assistir seus canais de TV a cabo, se você utilizará a TV como monitor para seu PC ou para jogar video-game, e por aí vai.

Isso tudo começa a complicar quando mesmo tendo todas as respostas para as dúvidas acima, você começa a se deparar com questões um pouco mais técnicas como: LCD ou plasma, qual resolução, polegadas, conexões (HDMI, RCA, digital, USB, etc…), potência, tempo de resposta, entre outras dezenas de parâmetros que vale sim muito a pena entender e comparar com precisão e segurança.

Para responder a todas estas questões, tenho certeza que através deste link o Google irá explicar muito bem o que siginifica cada um dos parâmetros mais comuns, e que podem pesar na decisão de qual televisor comprar.

Mas uma coisa é fato: o formato HD – Hight Definition - chegou para ficar. Não só como padrão para as transmissões televisivas, onde existe o HDTV, o formato HD pegou carona em outras mídias como o blue ray, jogos e consoles de videogames, computadores, e até mesmo na internet rápida.

Então, independentemente de qual seja a finalidade do uso da sua TV, uma coisa é certa: se você não tem problema com dinheiro, procure comprar uma TV do tipo Full HDTV com conversor integrado (sim, porque existe muita TV que “engana” dizendo que é “preparada para HDTV” ou “HDTV ready”, e na hora que você quiser assistir uma programação em HD de verdade você não irá conseguir receber o sinal com qualidade total).

Por que eu mencionei “problema com dinheiro”? Porque enquanto uma TV de LCD de 42″ que não é Full HDTV com conversor integrado custa cerca de R$ 3900, um modelo completo custa cerca de R$ 6000.

É de se espantar, verdade. Porém é também verdade que o preço destes televisores tendem a cair, assim como já caiu muito o preço das TVs de LCD e plasma mais comuns até hoje em dia.

Um modelo que eu aproveito para destacar, e que não posso deixar de colocar na minha wishlist, é este modelo de 42″ da LG (42LB7DF):

Então, se você depois de acessar o nosso tutorial ainda tiver dúvidas sobre qual televisor comprar, procure aquele aparelho que melhor se adapta à sua realidade e à sua necessidade de hoje. Mas claro, não se esqueça que a tendência é ser HD.

E se você puder investir um pouco mais neste eletroeletrônico que é um bem muito durável, invista em um Full HDTV que você não irá se arrepender.

Heute konnten wir endlich diesem Hilferuf folgen und das arme Fernseherlein von seinen Qualen erlösen. Es wird ab nächsten Samstag bei uns im Wohnzimmer ein neues Zuhause finden. YIPPY!! Nun kann scharf geschossen werden! Und natürlich auch geglotzt.

ENDLICH!!!  

Edit: Ach ja – das Konto motzt zwar. Aber das soll mal eben kurz die Klappe halten!!!!
