什么是IPTV 2005-4-22
Internet Protocol Television (IPTV) has become a common denominator for systems where television and/or video signals are distributed to subscribers using a broadband connection over Internet Protocol. Often this is in parallel with the subscriber's Internet connection, supplied by a broadband operator using the same infrastructure but over a dedicated bandwidth allocation.
IPTV is not a protocol itself.
IPTV is expected to grow at a brisk pace in the coming few years as broadband is now available to more than 100 million households worldwide.
