Zusammenfassung:	A system and method are provided for an AV device for use with a video player, one or more speakers, and encoded AV data. The encoded AV data includes multiplexed encoded video data and encoded audio data. The AV device is connected to the speakers via wireless channels. The AV device is able to determine channel delays associated with each wireless channel; synchronize program clocks of the video player and speakers; determine and modify buffer levels of each speaker; demultiplex the encoded AV data to obtain encode video data and encoded audio data; and provide prefetched portions of encoded audio data based on buffer levels.
