Content sharing is controlled by means of a token. The Content Token is allocated to<br />

participants by the highest level master conference.<br />

• The Content Token must be released by the participant that is currently holding it before<br />

it can be re-allocated.<br />

• After release, the Content Token is allocated to the participant that most recently<br />

requested it.<br />

• The Content Token can be withdrawn from a conference participant by using the <strong>RMX</strong><br />

web client only if the highest level master conference is running on the <strong>RMX</strong> unit.<br />

• The following table lists the bit rate allocated to the Content channel from the video<br />
