Abstract:
An audio playback apparatus for an input data stream (d0) delivered by an audio data source (1) in a standardized data format (F1), comprising an input decoder (2) for forming a first data stream (d1) which contains the audio information and is separated into its audio signal components (L, R) by means of an output decoder (5), and a control unit (4), wherein:the input decoder (2) further includes, in addition to a first data output at which the first data stream (d1) is provided, a second data output at which the data contained in the data field (D1) of the standardized data format (F1) is provided as a second data stream (d2);the second data output of the input decoder (2) has an additional decoder (3) connected thereto which detects a second data format (F2) possibly contained in the second data stream (d2) and routes the audio information of the second data format (F2) as a third data stream (d3) to the output decoder (5); andupon detection of the second data format (F2), the additional decoder (3) provides a detection signal (dz) to the control unit (4) which in response to said detection signal (dz) sets the output decoder (5) to the processing of the first or third data stream (d1, d3).
