Describe the format of RTP and RTCP packets.
Submitted by: AdministratorThe 32 bits of RTP packet format is as follows:- (L to R)
Bit 0-1:- Indicates version, currently 2
Bit 2:- P- indicates padding bytes
Bit 3:- X- Indicates presence of extension header
Bit 4-7:- CC- Contains number of CSRC identifiers that follows the header
Bit 8:- M- Current data has some special relevance (if set)
Bit 9-15:- PT- Indicates format of payload
Bit 16-31:- Sequence number
Timestamp: - 32bits - time stamp of packet
SSRC- Synchronization source identifier uniquely identifies the source of a stream.
CSRC -Contributing source IDs enumerate contributing sources to a stream which has been generated from multiple sources
Extension header: - first 32 bit word contains profile specific identifier and length specifier
The 32 bits of RTCP header format is as follows:- (L to R)
Bit 0-1:- Indicates version, currently 2
Bit 2:- P- indicates padding bytes
Bit 3 to 7:- Count of number of reception report blocks
Bit 8 to 15:- Type: - Determined RTCP packet type. Type can take values from 0 to 255
16 to 31:- Length- Length of RTCP packet - 1
SR: - Sender Report for transmission and reception from active senders
RR: - Receiver report for reception from in active senders
SDES: - Source description items
BYE- indicates end of participation
APP: - Application specific functions
