Abstract
A system and apparatus for establishing whether a received signal frame is an audio signal frame is disclosed. In one embodiment, the system includes a predetermined position in an audio signal frame containing a piece of secondary information for an audio characteristic of the audio data, with a selection device for selecting a succession of bits which is arranged at the predetermined position in the received signal frame. A decision-making device flags the received signal frame as an audio signal frame if the succession of bits represents the piece of secondary information.

A signal processing system comprising:
- a selection device configured for selecting a succession of bits which is arranged at the predetermined position in a received signal frame;
- and
- a decision-making device configured to flag the received signal frame as an audio signal frame if the succession of bits represents the piece of secondary information.
An apparatus for establishing whether a received signal frame is an audio signal frame which comprises audio data, a predetermined position in an audio signal frame containing a piece of secondary information for an audio characteristic of the audio data, comprising:
- a selection device configured device for selecting a succession of bits which is arranged at the predetermined position in a received signal frame;
- and
- a decision-making device configured device to flag the received signal frame as an audio signal frame if the succession of bits represents the piece of secondary information.
