Multicast RTP — An Overview

Multicast RTP allows a source to be displayed on multiple displays. This method uses a real-time variation of UDP (User Datagram Protocol) called RTP (Real-time Transport Protocol).

Multiple decoders can be part of the multicast group.

Figure 2. Multicast RTP Streaming

The source encoder uses RTP to send data to a multicast group. The source does not need to know the IP address of the decoders that are using the source.

RTP provides very low latency which is important for video streaming. Unlike other protocols, RTP packets include a time stamp. If packets are received in the wrong order, they are sorted into the correct order for display or discarded if the time stamp is out-of-date.

However, because RTP is a connectionless protocol, data delivery is not guaranteed. When data packets are lost (for example, due to excessive network traffic), the decoder devices carefully manage the data stream to minimize any image disruption.
