  • Patent number: 5023707
    Abstract: A system for enabling a plurality of audio signals respectively representing different languages to be recorded on a present-day video tape in a present day video tape recorder without requiring any additional space on the tape. The bands of audio signals representing the different languages are selectively reproduced so that anyone viewing the video program recorded on the video tape may select any one of a number of languages to accompany the video program. In accordance with the invention, the bands of audio signals representing the different languages are heterodyned to different frequency bands, and are caused to modulate a sub-carrier which, in turn, is inserted into the video signals representing the video content. This enables the audio signals to be recorded in the video tracks of the tape together with the video signals.
