ABSTRACT:
A system and method for high-quality variable speed playback of audio-visual (A/V) media is provided. The system receives an encoded visual signal and an encoded audio signal. The encoded visual signal is decoded to generate a decoded visual signal and the encoded audio signal is decoded to generate a decoded audio signal. The decoded audio signal is time scale modified to generate a time scale modified audio signal. The decoded visual signal and the time scale modified audio signal are then synchronized for playback at a predefined playback speed. Only partial decoding of the encoded audio signal may be performed to conserve processing power.
