Video Over IP

Video over IP is a term that describes a method of transmitting video, audio and data signals as packetized data over an IP network. Video broadcast over IP is a network-based one-way transmission of video file content. The endpoint is merely a passive viewer with no control over the session. Video broadcast can be either Unicast or Multicast from the server. In a Unicast configuration, the transmission is replicated by the server for each endpoint viewer. In a Multicast configuration, the same signal is sent over the network as one transmission, but to multiple endpoints or, simply, a group of users.

 Professional video over IP systems use some existing standard video codec to reduce the program material to a bitstream (such as an MPEG-2 transport stream), and then to use an Internet Protocol (IP) network to carry that bitstream encapsulated in a stream of IP packets. This is typically accomplished using some variant of the RTP protocol.
Carrying professional video over IP networks has special challenges compared to most non-time-critical IP traffic. Many of these problems are similar to those encountered in voice over IP, but to a much higher level of engineering requirements. In particular video conferencing service  provider widely used video over IP, there are very strict qualities of service requirements which must be fulfilled for use in professional broadcast environments.
