H.264 Cascade and SVC Optimized

The H.264 Cascade and SVC Optimized option maintains content quality and minimizes the amount of content refreshes that occur in large cascading conferences when participants connect or disconnect from the conference.

This option is the only available option automatically selected in SVC Only conferences .

The H.264 Cascade and SVC Optimized option uses fixed resolution and frame rate for SVC Only conferences. In AVC conferences, each content Line Rate and Content Setting has its own resolution and frame rate as summarized in Table 4-7.

In AVC conferences, endpoints that do not support the required content parameters

(Content line rate, H.264 protocol and Content Resolution), along with ISDN endpoints, can be connected as Legacy Endpoints and receive content through their video channel. This ensures that Content settings are not changed following the participants connection or disconnection from the conference. If the Send Content to Legacy Endpoints option is disabled, these endpoints will not receive content.

In SVC Only conferences, endpoints that do not support the required content parameters (Content line rate and Content Resolution) cannot share content.

Guidelines

•In Cascading conferences, the cascade link must be H.323.

•This is the only available Content sharing mode in SVC Conferencing Mode.

•H.323, SIP and ISDN participants are supported in AVC Conferencing Mode.

•H.264 High Profile is not supported.

•In MPM+ Card Configuration Mode, maximum supported content resolution is HD 720p.

•When H.264 Cascade and SVC Optimized is selected in AVC Conferencing Mode, the Send Content to Legacy Endpoints selection is enabled by default in the Conference Profile – Video Settings dialog box.

•In AVC Conferencing Mode, endpoints that cannot connect at a line rate required to support the conference Content Rate are considered Legacy Endpoints and will receive Content in the video channel.

•In SVC Conferencing Mode, endpoints that cannot connect at a line rate required to support the conference Content Rate will receive Content in the video channel.

Enabling H.264 Cascade and SVC Optimized Content Sharing in AVC Conferences

When H.264 Cascade and SVC Optimized is selected in AVC conference as the Content Protocol, an additional field, Cascade Resolution is displayed in the Content Video Definition pane. In SVC Conferencing Mode, the Cascade Resolution option is disabled.
