Patent ID: 6952452

Claim:
An apparatus comprising: a first circuit configured to (i) generate a random number signal, (ii) read a data signal, and (iii) generate one or more control signals; and a second circuit configured to (i) store said random number signal, (ii) receive and store a decoded video signal, and (iii) present said data signal, wherein (a) said first circuit is further configured to compare said data signal with said random number signal and (i) generate a first of said control signals when said data signal matches said random number signal and (ii) generate a second of said control signals when said data signal fails to match said random number signal and (b) (i) said random number signal is stored at one or more locations in said second circuit where portions or all of said decoded video signal are stored and (ii) said decoded video signal overwrites said random number signal when said second control signal indicates a video frame decoding skip has not occurred.
