<p>A multimedia system includes an integrated system and video decoder with an audio/video synchronization circuit (200) for substantially synchronizing the display of video images with audio playback. An audio presentation time stamp (APTS) (415) is detected in the compressed/coded audio data stream in the integrated system and video decoder and stored in a data latch (442). The compressed/coded audio data stream is fed to an audio decoder which decodes/decompresses the audio data and outputs an audio signal. The audio decoder detects when audio data corresponding to an APTS (415) had been output and sets a corresponding flag (213). The flag (213) indicates to the integrated system and video decoder that a corresponding audio segment had been decoded/decompressed and output. The integrated system and video decoder then synchronizes the video output with the audio output by repeating or skipping frames of video data.</p> |
