Description (partial)


Rewind tricks may appear to have regular "jitter" where a frame every so often appears out of place.  On some STBs this could manifest as scrambled video frames interleaved with working ones.  Other manifestations are possible.  The interval should be somewhat predictable.  The rate of the "jitter" should be somewhat predictable.  In our case with a key change every 8 seconds in our content, and a 4X trick we saw a frame jitter about every 2 seconds.  The jitter will occur DURING the playback of the trick (e.g. while rewinding), not at the start or end of the trick itself.  


The content must be encrypted.  It must be encrypted with PowerKey.  It must be using keys which change on a regular basis.
