Patent ID: 7310371

Claim:
An apparatus comprising: an output circuit configured to generate an output data stream in response to (i) a first intermediate signal, (ii) a second intermediate signal, and (iii) a third intermediate signal; a first processing circuit configured to generate said first intermediate signal in response to (i) a processed video signal and (ii) a prediction flag; and a second processing circuit configured to generate (i) said processed video signal, (ii) said second intermediate signal and (iii) said third intermediate signal in response to an input video signal, wherein said second processing circuit is further configured to generate a prediction macroblock signal, said processed video signal, said second intermediate signal, and said third intermediate signal in further response to a fourth intermediate signal, wherein said fourth intermediate signal comprises (i) said first intermediate signal when in a first mode and (ii) an inverse guantized, inverse transformed version of said first intermediate signal when in a second mode.
