SYSTEMS, METHODS, AND ARTICLES FOR ADAPTIVE LOSSY DECODING

Abstract:

Systems, methods, and articles that improve video playback on various devices by dynamically modifying the operation of a video decoder. The operation of a video decoder is dynamically simplified under certain conditions during video playback to provide higher decoding speeds that require less computing resources. A lossy control module is provided in the decoder that is operative to select different lossy decode levels to be used by the decoder at various detected operating conditions so that the decoding of a video can be dynamically sped up during playback of the video, thereby reducing or eliminating jittering or delayed playback
