Two similar ideas have been discussed i know of :

1. Video : using frame repetition for anime encoding

2. Encoding different language movie soundtracks into one single
multi-channel Ogg Vorbis file, using channel coupling or frame repetition
for size reduction, instead of storing several Stereo audio streams with the
movie, one for each language  , containing same or similar sound information
if there is no talking, but only background noise, etc.

Sorry if this is not exactly what you are talking about, but i thought it is
somehow related.
