Video Algorithm

Sets the compression algorithm that the MCU uses to

 

process video. Possible values include:

 

Auto

 

• H261. An ITU standard designed for two-way

 

 

communication over ISDN lines and supports data rates

 

 

which are multiples of 64Kbit/s. H.261 supports CIF and

 

 

QCIF resolutions.

 

• H263. Based on H.261 with enhancements that

 

 

improve video quality over modems. It supports CIF,

 

 

QCIF, SQCIF, 4CIF and 16CIF resolutions.

 

H264

 

The default is Auto.

 

Note

 

Selecting a video algorithm doesn't guarantee that it will be

 

chosen for a conference since the MCU device may

 

negotiate a different algorithm with the endpoints,

 

depending on the endpoint’s capabilities.
