AT&T IPTV: New Television Architecture

IPTV is the delivery of video content over Internet Protocol networks rather than through regular terrestrial, cable, and satellite television formats. Unlike downloaded content, IPTV provides the capability to stream the underlying resource continuously. It is used in conjunction with other technologies such as streaming video, multi-media transfer, and rich media. This enables IPTV services to deliver a high quality picture and sound to IP enabled devices such as video game consoles, digital cameras, webcams, handheld computers, and other Internet-enabled devices.

How Does IPTV Work? -

IPTV uses the technique of digital subscriber line or digital transmitters or modems to transmit live TV shows and movies to a subscriber’s computer. There are two ways in which IPTV may be delivered: direct and indirect. In direct mode, a single IPTV tuner is used to transmit all the programs and events from a given program source to the receiver’s receiver port Indirect IPTV mode uses an IPTV gateway which intercepts and alters IP packets before sending them on to their respective destinations. The difference in these two techniques results in two distinct types of IPTV services – traditional satellite television and IPTV.

Satellite television IPTV services are characterized by their large number of IPTV channels. The most popular type of satellite iptv provider is Sky Digital, who offers over 45 channels and special IPTV packages such as sports, movie and kids programs. All the popular Sky digital channels are offered in high definition (HD), which is the highest standard broadcast quality. High speed internet connection is required for IPTV services; this is usually either a cable connection or DSL.

The second type of IPTV service provider is AT&T U-verse. With the launch of the digital service, many traditional TV channels were replaced with premium channels provided by AT&T. AT&T’s U-verse also provides internet protocol television channels via digital transmission. The analog signal sent by U-verse can only carry a few channels of a broadcast format, while the digital signal can carry dozens of channels. This feature enables AT&T’s u-verse customers to experience a wider variety of TV shows and programs than any other satellite company.

An additional advantage of AT&T’s U-verse IPTV system is that it supports HDTV. Satellite providers only offer standard definition channels and feature such as “movie nights” are excluded. On the other hand, AT&T’s U-verse system offers HDTV, allowing full viewing of popular movie and TV programs. This facility has particularly caught the attention of football fans who love to watch football games with friends and family members across the globe. High definition quality is also a desirable feature of internet protocol tv because of the sharp picture clarity, clear pictures and audio.

Lastly, AT&T’s U-verse broadband network also supports the use of streaming devices like Apple TV. With the integration of streaming technology like apple tv, internet streaming becomes more convenient. AT&T’s IPTV solutions thus far are quite impressive and the combination of high-speed broadband, its services and a wide array of high-definition TV channels should make internet tv viewing an even more popular activity.
