Content Channel Support - Cisco TelePresence Server 7010 Product User Manual

Content channel support

Most telepresence endpoints support the use of a second video channel known as the content channel.
This is typically used for presentations running alongside live video.
H.323 systems use a protocol called H.239 to receive and send the content channel video.
n
SIP systems use a protocol called BFCP for content.
n
Cisco CTS systems and other TIP systems use TIP to control content sharing.
n
Although the content channel is enabled system-wide by default, the TelePresence Server must cater for
endpoints that do not support the second video channel. Go to
Allow content in main video.
With this feature selected, the TelePresence Server sends the content in the main video channel to
those endpoints. The content channel is composed with the normal video while the content channel is
active (content is displayed in largest pane and other participants' video streams are centered continuous
presence panes across the bottom of the display).
Content sharing is enabled by default. To edit this setting for a conference, go to
conference name > Configuration
In each conference, only one participant can send a content channel video stream at a time. To enable
another participant to become the presenter, either the active presenter must stop sending content or the
TelePresence Server must allow participants to take over the content channel.
Content channel configuration settings
When you add a new conference or configure an existing conference, you can choose whether the
content channel is allowed in that conference with the Content channel setting.
The Content channel is Enabled for conferences by default, which means that participants are able to
contribute content channel video for the other conference participants to see.
If the conference's Content channel is Disabled, content sharing is not allowed and no participants can
contribute content.
For a participant to contribute a content channel requires the following:
That participant's endpoint must be configured to allow content channel video contribution:

1. Go to Endpoints

Either the participant must be the only active presenter or the TelePresence Server must allow

automatic content handover:
1. Go to Configuration > System
2. Check the box labeled Automatic content handover.
For a participant to see the shared content on a single-screen endpoint, the endpoint must support
content sharing, or have Allow content in main video enabled.
The TelePresence Server sends the content channel to one endpoint in an endpoint group; that endpoint
must support the content channel:
To choose which endpoint in the group receives the content channel video:
