Bitrate regulation in
progress
progress
Filtered
The regulation algorithm is estimating the
incoming bitrate to compensate for the
difference in PCR clocks on the source
encoder and the IP receiver. While this
alarm is active, the output bitrate may be
tuned beyond the limits of the ASI
specifications.
