2.2.1.12.7 MaxDiffSndTime

This parameter specifies the maximum latency, in milliseconds, between the video and the audio streams during the acceleration interval. The duration of the acceleration interval is specified by the LastTime parameter.

If an ASF payload that contains audio data has a presentation time value that is lower than the presentation time value of the most recent ASF payload that contained video data, the audio stream is considered to lag behind the video stream. The MaxDiffSndTime parameter MUST specify the largest such lag, expressed as a non-negative number.

If the video stream consistently lags behind the audio stream during the acceleration interval, the MaxDiffSndTime parameter MUST specify the largest such lag, as a negative number.

If the content does not have both an audio and a video stream, the value of this parameter MUST be 0.

More information about ASF presentation time is specified in [ASF] section 5.2.3.

The syntax of the MaxDiffSndTime parameter is defined as follows.

 XSP-MaxDSTime  = "MaxDiffSndTime=" [ "-" ] 1*10DIGIT

The value of the MaxDiffSndTime parameter MUST be an integer in the range from 0 through 2,147,483,647.
