A playback apparatus includes a data source () that provides a data stream signal (d), and a device () responsive to the data stream signal. The device forms a first data stream (d) in a first data format (F), wherein the first data stream (d) includes a data field (D) that is encoded in a second data format (F). A code converter () is responsive to the first data stream (d), and converts selected parts of the first data stream (d) to a second data stream (d) that has data encoded in a third data format (F). An output decoder () forms playback signals from the second data stream (d). The playback signal may be audio and/or video signals that are presented to the appropriate audio transducer or display device for presentation to a playback apparatus user(s).

Playback apparatus

An audio playback apparatus for an input data stream (d0) delivered by an audio data source (1) in a standardized data format (F1) is disclosed comprising an input decoder (2) for forming a first data stream (d1), which contains the audio information and is separated by means of an output decoder (5) into its audio signal components (L, R). In addition to the first data stream (d1), the input decoder (2) generates a second data stream (d2) which corresponds to the data contained in the data field (D1) of the standardized data format (F1), and which is fed to an additional decoder (3) that detects a second data format (F2) possibly contained in the second data stream (d2) and passes the audio information of the second data format (F2) as a third data stream (d3) to the output decoder (5). Upon 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 this detection signal (dz), sets the output decoder (5) to the processing of the first or third data stream (d1, d3).
