L5 RTP: Lists these 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.
Note:
For 2022-6 signals, the status indicator turns red if the Marker Bit Frequency
does not match the frame rate indicated in the HBRMT header. For 2110 signals, the
status indicator turns red if the Marker Bit Frequency does not match the measured
field rate of the detected format.
– 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.
Note:
The Payload type for ST2110 streams should be between 96 and 127. The Payload
type is set by the user/device.
– Sequence number: RTP sequence counter that changes by one for each RTP
Media Datagram that is sent.
Note:
The status indicator turns red if the received RTP sequence numbers do not
change 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: For 2022-6 signals, the status indicator turns red if the Time Stamp field does
not change at the rate of 27 MHz on every packet. For 2110 signals, the status indicator
