Field Name
Description
Possible Values
A/V Disc
The sum of the discontinuity
errors encountered on either the
audio or video streams that have
occurred since the current
stream was tuned
Note: Discontinuity errors
indicate that packets were
transmitted out of order or with a
gap between them. This
indicates data loss.
