Classification: CPC G  H | IPC G

Claim 16:
17. Sink device for processing a modified bitstream in MPEG-4 audio format, wherein the device includes:
a) a receiver configured to receive a modified bitstream including coded media data, payload of additional uncompressed PCM audio data and an MPEG-4 audio bitstream extension mechanism, wherein the MPEG-4 audio bitstream extension mechanism is a data stream element (DSE);
b) a bitstream parser configured to parse the modified bitstream into the coded media data and the payload of the additional uncompressed PCM audio data, wherein the bitstream parser is further configured to parse the modified bitstream based on identifying the MPEG-4 audio bitstream extension mechanism in the modified bitstream;
c) a core decoder configured to core decode the coded media data to obtain core decoded media data;
d) a mixer configured to mix the core decoded media data and the additional uncompressed PCM audio data to obtain an output signal; and
e) a control unit configured to output the output signal.
