Content Sharing Reference Tables

Resolutions and Content Rate Reference Tables

H.263 Content Rate Table

The table below describes the content rates for both Highest Common and Fixed content bit rates.

H.264 Resolution per Content Rate Table

The table below describes the resolution as negotiated by the MCU according to the content rate.
The values in the tables below indicate the maximum negotiated content rate (for both H.263 and
H.264) and resolution/frame rate (only for H.264).
When using Highest Common, endpoints may lower the content parameters, whereas when using
fixed rate, endpoints must comply with the content parameters as determined by the MCU.
The actual content parameters used by the content sharing endpoint are determined by that endpoint,
and may be lower.
