Abstract
Disclosed is a method and system for reducing audio artifacts and/or avoiding invalid reference memory in a compressed video decoder due to processor congestion. The system and method includes decoding compressed frames of video data, and decoding compressed frames of audio data. The system and method determines whether audio data can be generated without audio artifacts. If it is determined that audio can be generated without audio artifacts, then images corresponding to the decoded frames of video data, respectively, are subsequently displayed. If however it is determined that the audio can not be generated without artifacts due to processor congestion, images are displayed and redisplayed while processor power is shifted to decoding frames of audio data.
