Low resolution during presentation sharing in a CMR Meeting.
Presentation shared in a CMR Meeting is of low quality, when shared via a display cable from a TelePresence EndPoint.
Poor quality in a multipoint video conference during presentation sharing in a CMR Meeting.
This issue may occur when the Conference Presentation Relay Quality and the Video Input Source Quality settings in a multipoint video conference, specify whether to give priority to high frame rate or to high resolution, from the presentation source.
As an Admin, working on the TelePresence Endpoint setup and configuration. It is important to figure out, which video input source is being used for content sharing, to make sure that one video input is set for sharpness and the other video input sources, that are intended for cameras (For example: main video 1 and main video 2, which can be used in some environments to toggle between different views for the room) should be set for motion.
Conference Presentation Relay Quality:
This configuration applies to video systems that are using the built-in MultiSite feature (optional) to host a multipoint video conference. When a remote user shares a presentation, the video system (codec) will transcode the presentation and send it to the other participants, in the multipoint conference. The RelayQuality setting specifies whether to give priority to high frame rate or to high resolution for the presentation source.
The video input source responsible for presentation relay quality, must be set for sharpness.
Video Input Source Quality:
When encoding and transmitting video, there will be a trade-off between high resolution and high frame rate. For some video sources, it is more important to transmit high frame rate than high resolution, and vice versa. The Quality setting specifies whether to give priority to high frame rate or to high resolution, for a given source.
The video input source responsible for video, must be set for motion.
- Motion: Gives the highest possible frame rate. It is used when there is a need for higher frame rates, typically when a large number of participants are present or when there is a lot of motion in the picture.
- Sharpness: Gives the highest possible resolution. It is used when you want the highest quality of detailed images and graphics.
Note: You need to be an Admin for the codec, to make the above system changes by going to the System Configuration page on the codec's web interface.
