PRISM Media Analysis Platform User Manual
L5 RTP: Lists the following parameters of the L5 RTP (Real Time Protocol)
layer. RTP Datagrams are defined in IETF RFC 3550.
Version: Identifies the version of RTP and should be a value of 2.
Padding: Indicates whether padding bytes are present. Possible values
are:
false: Indicates no extra padding bytes are at the end of the RTP
packet.
true: Indicates that padding octets have been added to the RTP packet
that are not part of the payload.
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:
98: Indicates a SMPTE 2022.6 High Bit-rate Media transport.
99: Indicates a SMPTE 2022.5 High Bit-rate Media Forward Error
Correction (FEC) payload.
33: Indicates a SMPTE 2022.2 Constant Bit Rate MPEG-2 Transport
Stream Adaptive Sample Picture Encapsulation (ASPEN) payload.
Sequence number: RTP sequence counter that increments by one for
each RTP Media Datagram that is sent.
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.
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.
