Claim Text:
1. A method for decoding a unified bitstream generated by an encoder, wherein the unified bitstream is indicative of first encoded audio data that have been encoded in accordance with a first encoding protocol and additional encoded audio data that have been encoded in accordance with a second encoding protocol, and the unified bitstream is decodable by a first decoder configured to decode audio data that have been encoded in accordance with the first encoding protocol, and by a second decoder configured to decode audio data that have been encoded in accordance with the second encoding protocol, wherein the first encoded data is interleaved with the additional encoded data with a start of a first frame of the first encoded data being provided before a start of a first frame of the additional encoded data, with an end of the first frame of the first encoded data being provided after the start of the first frame of the additional encoded data, with the start of the first frame of the additional encoded data being provided before a start of a second frame of the first encoded data, and with an end of the first frame of the additional encoded data being provided after the start of the second frame of the first encoded data, said method including the steps of: (a) providing the unified bitstream to a decoder configured to decode audio data that have been encoded in accordance with the first encoding protocol; and (b) decoding the unified bitstream using the decoder configured to decode audio data that have been encoded in accordance with the first encoding protocol, including by decoding the first encoded audio data and ignoring the additional encoded audio data.
