Method and apparatus for encoding or decoding audio or video frame data

摘要

For broadcasting purposes a multi-channel audio encoder board has been designed. A requirement for such encoders is that they are able to operate with different encoding parameters. It may happen that encoding parameters change during encoding operation. In order to avoid the output of invalid data the encoding parameters required for a specific processing path are added to the input streams for the audio channels and become linked with the associated audio data and are stored in various buffers together with its audio data, i.e. the corresponding encoding parameters are kept linked with the audio data to be encoded throughout the encoding processing.
