CMAX and VRX Buffer Graph
ST2110-21 specifies a timing model for ST2110-10 video RTP streams with these
parametric models:
Note:
The CMAX and VRX trend graphs are only available for 2110 streams.
Note:
Make sure the input signal and PRISM are locked to PTP for these
measurements.
•
A network compatibility model to regulate the burst characteristics of senders,
which promotes the compatibility with the switches. The CMAX section provides a
trend graph for this type of modeling.
•
A virtual receiver buffer model to ensure there is no buffer overflow or underflow in
the receiver that could cause the packet loss and picture quality degradation. The
VRX Buffer section provides a trend graph for this type of modeling.
Both trend graphs help engineers properly setup the packet delivery timing in the
RTP packet sender.
