Patent US 5,587,979

A system for transferring audio and/or video information via an information carrier, e.g., DAT, CD or CDV. In the R-W subcode channels of a CD-signal, textual or visual information about the audio and/or video signal is recorded. This information is divided into packets. Packets containing information of different categories are interleaved. After reading the information from information carrier, the packets of a selected category are separated from information read. This system of transferring additional information (in packets) allows the use of a separate packet category for each of a number of different languages, so that a user can select a language with which he or she is most familiar. In addition, menu information, including coded menu text lines and command codes, can be recorded in the R-W subcode channels as packets for interactive control of the read-out of the audio and/or video information or the control of other connected devices.
