Polycom 1500/1800/2000/4000 manual Guidelines for Sharing Content Using H.264 HD

Sharing Content During Conferences

When this protocol option is selected, content minimal bit rate is determined. For more information, see Setting the Minimum Content Rate for Each Content Quality Setting for H.264 HD.

Content parameters are determined by the Collaboration Server applying the Highest Common principle (see Highest Common), for H.264 media content protocol only.

Guidelines for Sharing Content Using H.264 HD

●Only endpoints supporting HD H.264 content (at least HD720p5) can share content.

●Base or high profiles are auto-selected based on endpoints and MCU capabilities (see table H.264 AVC (non-TIP) conferences).

Setting the Minimum Content Rate for Each Content Quality Setting for H.264 HD

System flags determine the minimum line rate required for endpoints to share H.264 high quality content for each of the Content Settings: Graphics, Hi Resolution Graphics and Live Video.
