Description (partial)

When the Customer orders VoD content, the Set Top Box is not able to render the stream containing AC-3 Audio after a few seconds. But when the Customer tunes to a content that is being broadcast, then the Customer does not observe any problem.

In the Tier-based scrambling setup, when the Customer orders VoD content, the RFGW-1 would stream it in the Clear until the CryptoPeriod Boundary and then starts scrambling the content in the next CryptoPeriod after updating the CA Descriptor in the PMT. The STB is having a problem with the 'Clear -> Encrypted' transition.

But when the Customer tunes/zaps to a content that is being Broadcast, then they do not observe this problem as it is more likely that the content is already being scrambled when the Customer tuned to that content.
