title: CSRC and SSRC in RTP
body: <p>I am very new to RTP , can some one explain about the CSRC and SSRC in general?</p>
  
  <p>From <a href="http://www.rfc-editor.org/rfc/rfc3550.txt">http://www.rfc-editor.org/rfc/rfc3550.txt</a> ,
  what it says is : The SSRC field identifies the synchronization source. Does it mean , in network there may be many senders who are contributing to RTP (multicast network) and to identify from which source the packet is coming??</p>
  
  <p>CSRC : Contributing source (CSRC): A source of a stream of RTP packets that has contributed to the combined stream produced by an RTP mixer (see below). Did not understand.</p>
  
  <p>can some one explain with example please?
  Thanks</p>
