The following requests or commands will be ignored during an Annex D
broadcast:
•Video forcing by the operator, at the conference level and at the
participant level
•Video forcing by the chairperson, at the conference level and at the
participant level
•Video forcing by an endpoint at the conference level
•Request to mute any endpoint (including the slide sender)
•Request to start or end the Lecture mode
•Changing the Lecture mode parameters
•Changing the Video Layout parameters
Table6-2 lists the transmission standards supported by Annex D.
To run this feature, video cards of version 1.4x and higher, are recommended.
Sending an Annex D image using video cards of version 1.2x and below (1 MB
cards), will cause the VCP of the slide sender to stop encoding the video while
receiving the slide. During this time, the image of the sender freezes at the remote
sites.
