Abstract
A method, medium, and apparatus hierarchically coding/decoding audio data, such as bit sliced arithmetic coding (BSAC), such that payloads of audio data and extension data can be grouped and interleaved according to priority so that some groups of the payloads are dropped, and the remainder of groups are transmitted. Therefore, extension data that is more important than a top layer of audio data, in terms of reproducing of original sounds, can be transmitted with priority.
Claims24
A method of processing/transmitting a bit-stream, the method comprising:
- coding audio data and at least one extension data for the audio data;
- truncating selective payloads resulting from the coding;
- and
- transmitting the truncated payloads.
An apparatus processing/transmitting a bit-stream, the apparatus comprising:
- a coder to code audio data and at least one extension data for the audio data;
- a truncator to selectively truncate payloads resulting from coding of the coder;
- and
- a transmitter to transmit the truncated payloads.
A method of receiving/processing a bit-stream, the method comprising:
- receiving payloads having truncated portions;
- restoring the payloads having the truncated portions to original form restored payloads;
- and
- decoding audio data included in the restored payloads and at least one extension data for the audio data.
An apparatus receiving/processing a bit-stream, the apparatus comprising:
- a receiver to receive payloads having truncated portions;
- a restorer to restore the payloads having the truncated portions to original form restored payloads;
- and
- a decoder to decode audio data included in the restored payloads and at least one extension data for the audio data.
