Figure E.2: Transmitter Media Lan Performance - Avocent Emerge MPX Installer/User Manual

a. Primary Video Resolutions: This field contains a list of all resolutions that the Primary
Receiver has reported to the transmitter. These values would have come from the display
device itself or from the Display Settings page of the receiver.
b. Video Resolutions in Use: This field indicates the list of resolutions that have been
reported to the source device.
c. RGB Video Resolutions Stored: This field indicates the resolutions that are currently
stored in the Active EDID string of the transmitter.
The Transmitter Performance and Receiver Performance tables on the Media LAN Performance
web page of an MPX transmitter, illustrated in Figure E.2, provide real-time status of media LAN
bandwidth utilization. The Current Video Data Rate is the target transmit data rate. This value
should fall between the maximum data rate and the minimum data rate settings. The Transmitted
Total Bitrate is the amount of audio and video data that the transmitter has actually transmitted per
second since the last page update. Bitrate status for retransmitted data is also provided. The receiver
table indicates the amount of real-time data received from the media LAN as well as the amount of
retransmitted, recovered and lost data. Chronic status of missing data is a symptom of an adverse
condition that should diagnosed and resolved.
