ABSTRACT:
Based on a series of video data for producing one or a plurality of text displaying images and a series of accompaniment MIDI data, a signal processing circuit (1) prepares a quasi video signal containing the two kinds of data as arranged in alternating fields or in alternating pluralities of fields in time series and identification data for identifying the series of video data and MIDI data. The quasi video signal is transmitted to terminal units (5) for users via a CATV or like transmission path. The terminal unit extracts from the quasi video signal fields of MIDI data and video data containing identification data specifying a piece of music selected by the user, and reproduces the accompaniment of the selected piece and displays the text thereof based on the extracted data.
