IPTV refers to Internet Protocol Television, a technology that allows households and businesses to receive television programming through a broadband connection. It is a service that requires subscription. In addition to this, users need to have an IPTV set-top box to enjoy this technology.
IPTV presents several advantages over regular television. Interactive communication is the most unique quality of IPTV. Using Internet protocols for two-way communication, IPTV can allow viewers at home to directly participate in quiz shows aired by certain TV channels.
Another application is the picture-in-picture viewing. This feature gives viewers the ability to watch a particular event simultaneously in multiple angles. Picture-in-picture viewing also lets viewers browse through other channels while watching one main show.
IPTV also has options for the viewer to rewind, fast-forward, or pause the show he is watching. Furthermore, IPTV can enable digital video recorders or DVR’s to record more than one broadcast at the same time.
IPTV also supports remote programming. For example, if the user is in a meeting and his favorite TV show is about to start, he can simply use his mobile phone to remotely set the IPTV box to record the show.
Aside from this, other Web services can also be included along with IPTV. While the viewer is watching IPTV, he can receive e-mail alerts and instant messages. If a digital phone is packaged with IPTV, the user can see a caller ID window when someone calls.
IPTV may generally have a lower price compared to other similar services. This is because IPTV offers more efficient streaming of video and audio than other digital transmission technologies.
