发明名称 SYSTEM AND METHOD FOR PROVIDING A VARIABLE FRAME RATE AND ADAPTIVE FRAME SKIPPING ON A MOBILE DEVICE
摘要 <p>A processor and method are provided for decoding a multimedia file having video and audio data streams that are configured to be played in synchronization. Frames of the video stream are decoded and played with the audio and, to compensate for saturation of the processor usage, two procedures are performed. The first procedure operates at a first periodic interval and slows down the frame rate to reduce processor usage if needed. The second procedur e first attempts to speed up the video to catch up to the audio if they are out of sync and if this cannot be done in the next time interval, the decoding of a select number of frames is skipped such that the video and audio data streams are resynchronized.</p>
