Hi Paul, all;

What is the maximum frame per second for H.261 and H.263? Is this indicated in the TCS? if yes, where in the OLC messages do I indicate the actual frame rate.

Regards, charles

Charles,

H.323 doesn't care what the audio clock rate is. That's specific to the audio encoding:

A.5.1/H.225.0v4: "The clock frequency is dependent on the format of data carried as payload and is specified statically in the profile or payload format specification that defines the format, or may be specified dynamically for payload formats defined through non-RTP means."

A.12/H.225.0v4: "For each payload type defined, the profile must specify the RTP timestamp clock rate to be used..."

Hi,

How can H.323 support audio clock rates higher than 8khz. Regards,

charles
