PRISM MPI and MPX Media Analysis Platform User Manual
Extension: Indicates whether an extension is present. Possible values are:
false: Indicates no extension is present.
true: Indicates an extension is present.
CSRC: Identifies the Contributing Source IDs. This value should be set
to zero.
Marker: This value should be set to 1 to indicate the last Media Datagram
of the video frame. The value is set to 0 for all other Media Datagrams
and should be 0 for most packets.
Payload type: Identifies the type of RTP payload.
Sequence number: RTP sequence counter that increments by one for
each RTP Media Datagram that is sent.
NOTE. The status indicator will turn red if the received RTP sequence
numbers do not continuously increment by 1 on every packet.
Time Stamp: The timestamp reflects the sampling instant of the first
octet in the RTP datagram. This value can be used to determine packet
sequence errors and jitter calculations to be made.
NOTE.
The status indicator will turn red if the Time Stamp field does not
increment at 48 kHz rate on every group of audio samples.
SSRC: Identifies the Synchronization Source ID and is set in compliance
with RFC3550. This identifier is chosen randomly and should be unique
so that no two SSRC have the same value with an RTP session.
