ABSTRACT:
Finite audio and video signals are subjected to a digitizing code format and converted into blocks of audio and video words respectively. For the transmission of these blocks via a record carrier (2), for example a compact disc, the words are arranged in frames, Each frame has a frame header (8.1) and a data field (8.2). Such a data field contains information words in the form of either audio words or video words. The header indicates whether the associated data field contains audio words or video words. At least two audio signals associated with a video signal are recorded on the record carrier. An example of this is a "slide show" in which the explanatory text is available in two or more languages (e for English, f for French). The frame header of the frames containing an encoded audio signal also indicate to which one of the two or more audio signals the information words in an audio frame belong. Further, reference signals and additional frames (6)are recorded in the record carrier. For each of the two or more audio signals associated with a picture (or video) signal the additional frames contain time information on the time interval between the instant of detection of a reference signal after reading and the instant at which a picture signal read is to be displayed on a monitor (50). An apparatus for recording or reproducing the above signals is described.
