  2. Multicast - Wikipedia

    en.wikipedia.org/wiki/Multicast

    The concept of interactive multicast, for example using IP multicast, may be used over TV broadcast networks to improve efficiency, offer more TV programs, or reduce the required spectrum. Interactive multicast implies that TV programs are sent only over transmitters where there are viewers and that only the most popular programs are transmitted.

  3. Digital multicast television network - Wikipedia

    en.wikipedia.org/wiki/Digital_multicast...

    A digital multicast television network, also known as a diginet or multichannel, is a type of national television service designed to be broadcast terrestrially as a supplementary service to other stations on their digital subchannels. Made possible by the conversion from analog to digital television broadcasting, which left room for additional ...

    IP multicasting was first developed by Steve Deering while at Stanford University for which he received the IEEE Internet Award. [10] The MBONE was a long-running experimental approach to enabling multicast between sites through the use of tunnels. While the MBONE is no longer operational, there is renewed interest in tunneling multicast ...
