Claim 15:
16. Source device for generating a modified bitstream in MPEG-4 audio format, wherein the device includes:
a) a receiver configured to receive a bitstream including coded media data;
b) an embedder configured to generate payload of additional uncompressed PCM audio data and to embed the generated payload in the bitstream to obtain a modified bitstream including the coded media data and the payload of the additional uncompressed PCM audio data wherein the embedder is further configured to embed the generated payload in the bitstream by transporting the payload in the modified bitstream via an MPEG-4 audio bitstream extension mechanism, wherein the MPEG-4 audio bitstream extension mechanism is a data stream element (DSE); and
c) a control unit configured to output the modified bitstream to a sink device.
