org.mobicents.sdp

Class RTPAudioFormat

java.lang.Object

org.mobicents.sdp.Format

org.mobicents.sdp.AudioFormat

org.mobicents.sdp.RTPAudioFormat

All Implemented Interfaces:

Serializable, Cloneable, RTPFormat

public class RTPAudioFormat
extends AudioFormat
implements RTPFormat

This represents the RTP Audio Format. The difference being RTPAudioFormat also carries the pay-load. For example look at SDP

 m=audio 8010 RTP/AVP 0 8 97 
 a=rtpmap:0 PCMU/8000 
 a=rtpmap:8 PCMA/8000
 a=ptime:20     
 

here pay-load is 0 for PCMU, 8 for PCMA
