VLC uses this protocol (or access module) to read data from a device or network. This protocol is handled by the sdp module. |
SDP stands for "Session Description Protocol". It is used to describe a streaming session. SDP data is usually carried over SAP, RTSP or in dedicated files.
The idea behind SDP is that you can store critical stream information in the SDP and distribute this over a reliable connection (such as HTTP or RTSP). Then you can stream the raw codec data over a lossy connection, such as RTP without the need for a container.
