Sharing Content Using Multiple Content Resolutions Mode
In Multiple Content Resolutions mode, content is shared in multiple streams, one for each
video protocol: H.263 and H.264. This allows endpoints with different protocols to connect
and disconnect without having to restart Content sharing in the middle of a conference.
Guidelines for Sharing Contents using multiple Content Resolutions
• Multiple Content Resolutions is supported only in:
— MPMx Card Configuration Mode.
— AVC CP conferences.
• When Multiple Content Resolutions is enabled, Content is always provided to H.264 HD
endpoints. Resolutions of HD720p30 and HD1080p15 are supported.
• When Multiple Content Resolutions is enabled, the Send Content to Legacy Endpoints
option is selected and can not be deselected.
• Additional resources are allocated to the conference (in addition to the resources
occupied by the conference participants) for processing the content:
— Resources are allocated only when content sharing is started.
— If only HD720p30 content is provided, 1.5 HD video resources are allocated to the
conference.
Multiple Content Resolutions option is not supported in Ultra Secure Mode.
