Real-time Multimedia Traffic
Example: a video conference in which a camera is connected to a server that transmits video information as it is produced. Everything that happens at the server site can be displayed on the computer at the client site. This is both multimedia (video) and real-time traffic (production and use at the same time).
In order to ensure playback timing and jitter removal timestamps are required.
In order to ensure the presence and order of data a sequence number is required.
Most of the real-time multimedia applications are video conferencing where several clients receive data. Therefore the multicast mode is preferred.
In order to deal with congestion a mechanism for sender notification and change of encoding parameters must be provided.
In order to display streams generated by different standards the choice of encoding must be provided.
In order to display audio and video streams (and user data like titles) within a single A/V session mixers are required.
In order to use high bit rate streams over a low-bandwidth network the translators are required (multimedia payload encoders and decoders)[/caption]
