Abstract
An information signal representing audio and/or video information is read together with a series of first data packets representing textual subinformation relating thereto from a record carrier on which such signal and data packets have been recorded together. A series of second subinformation data packets having the same format as the first subinformation packets are interleaved therewith so as to form a subinformation signal, such signal being combined with the main information signal to form a transmission signal for transmission to a receiver, the second subinformation packets representing textual subinformation unrelated to the main information signal. A receiver for such transmitted signal reproduces the information in the main information signal together with selected portions of the textual subinformation represented by the data packets, such selection being effected by a user in accordance with menus represented by the data packets and displayed on a video display unit of the receiver.
