Until now, a Server could operate in either Full Monitoring Mode, or Monitor Only Mode, so depending on the quantity and type of sources, a configuration setup had to be done with Servers operating in either one of the modes ahead and for the duration of the deployment.
TAG’s New Adaptive Monitoring
The new “Adaptive Monitoring” feature allows operating in a Hybrid mode where the selection of which mode to operate in is made per Input Source, and each Server can be dynamically and adaptively assigned to monitor any combination of the two operating modes.
The constraint to set which mode each Server is operating in is now alleviated, especially in the Cloud deployment where Multicast support is not available for the most part, so combined deployment of Full Monitoring and Monitor Only modes is not supported in the same deployment.
Adaptive Monitoring Capabilities
The essence of the new Adaptive Monitoring feature is that it enables the user to choose per channel the monitoring mode: Full, Light, or Extra Light, with the ability to change it dynamically.
...
Full Monitoring : Requires one full license and regular Hardware usage (SD Points depending on the source)
Light Monitoring : Requires one full license and 0.33 (1/3) HW usage (SD Points)
Extra Light Monitoring : Requires one full license and 0.2 (1/5) HW usage (SD Points)
Light / Extra Light Monitoring Functionality
When a channel is in Light or Extra Light mode and is assigned to the Mosaic Tile by either a Manual, API command, or CED-triggered need, and there are Hardware resources available in the Server, the channel is monitored or needs to be displayed on, the monitoring is upgraded to Full mode until further change, and it can be displayed on a Mosaic Tile. If no hardware resources are available on the Monitoring Server, an error icon is displayed on the Mosaic Tile, indicating no hardware resources to perform the desired action.
...
This mode is not available or relevant for uncompressed channels since there is no decoding of compressed content. CPU resources are always the same, and the Live Production application needs to see real-time live video on the Mosaic Tiles.
It is, however, available for all compressed formats MPEG-TS, Zixi, J2K, OTT, etc.
Benefits for our customers
The New Adaptive Monitoring allows:
...
Zero Compromise Optimizes CPU Usage without sacrificing error detection.
...
Zer0 Friction Operational flexibility and Agility when it comes to monitoring the channels.
...
Making Cloud operation much simpler, flexible, and agile when monitoring a massive # of OTT channels on the Cloud.
...
When source is using Light mode, the transport layer and audio are fully monitored, as if it was full mode.
Video is monitored as following:
Decoding starts with the first I frame and go for about 20-30 frames.
Decoding stops for 3 seconds.
After 3 seconds decoding is restarted, awaiting for the next I frame to begin (Interval might be slightly longer than 3 seconds).
Once the I frame is received, decoding starts and go for another 20-30 frames.
Steps 1-4 is repeated.
Extra-Light mode works the same way except for the decoding stop interval which is 5 seconds (step 2).
