Claims
- 1. A signal recording medium which, based on a series of video data for producing one of a plurality of images and MIDI data for producing a series of sounds corresponding to the video data, has recorded thereon 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 distinguishing the series of video data and MIDI data from other series of video data and MIDI data, the identification data being written in a control signal block provided in a vertical blanking period of the quasi video signal.
- 2. A signal recording medium as defined in claim 1 wherein the quasi video signal has a television broadcasting signal format.
- 3. A system for reproducing sounds and images from a signal recording medium which, based on a series of video data for producing one of a plurality of images and MIDI data for producing a series of sounds corresponding to the video data, has recorded thereon 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 distinguishing the series of video data and MIDI data from other series of video data and MIDI data, the system comprising pickup means for reproducing the quasi video signal from the signal recording medium, and a plurality of terminal units for reproducing desired sound and images from the quasi video signal reproduced from the pickup means, each of the terminal units comprising:
- selection means for preparing identification data for specifying the sounds and images to be reproduced,
- signal processing means for extracting from the received quasi video signal the series of video data and MIDI data containing the selection signal prepared by the selection means,
- sound emitting means for outputting the MIDI data extracted by the signal processing means, and
- display means for outputting the video data extracted by the signal processing means.
- 4. A system as defined in claim 3 wherein the quasi video signal has a television broadcasting signal format.
- 5. A system as defined in claim 4 wherein the identification data is written in a control signal block provided in a vertical blanking period of the quasi video signal.
- 6. A system as defined in claim 3 wherein the signal processing means of the terminal unit has memory means for storing a series of MIDI data and a series of video data, and feeds the MIDI data and the video data read out from the memory means to the sound emitting means and the display means respectively.
