Elements of the DATA tab display.
•
L3 IP
o
Source Addr
: Lists the source addresses for the L3 IP layer.
o
Destination Addr
: Lists the destination addresses for the L3 IP
layer.
•
L4 UDP
o
Source Port
: Lists the source ports for the L4 UDP layer.
o
Destination Port
: Lists the destination ports for the L4 UDP
layer.
•
L5 RTP
: Lists these parameters of the L5 RTP (Real Time Protocol)
layer. RTP Datagrams are defined in IETF RFC 3550.
o
Version
: Identifies the version of RTP and should be a value of 2.
o
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.
o
Extension
: Indicates whether an extension is present. Possible
values are:
§
false
: Indicates no extension is present.
§
true
: Indicates an extension is present.
o
CSRC
: Identifies the Contributing Source IDs. This value should
be set to zero.
o
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 will turn red if the
Marker Bit Frequency does not match the frame rate indicated in the
HBRMT header. For 2110 signals, the status indicator will turn red if
the Marker Bit Frequency does not match the measured field rate of
the detected format.
o
Payload type
: Identifies the type of RTP payload.
o
Sequence Number
: RTP sequence counter changes in increments
of one for each RTP Media Datagram that is sent.
o
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.
