ABSTRACT:
Wide band measured data signals are recorded synchronously with television signals by time and/or frequency multiplexing techniques. Measured data signals are scanned by a multiplexer, converted to digital form, and temporarily stored. Signals from the store together with auxiliary information signals are converted from parallel to serial form and suitably coded for multiplexing. For time multiplexing, the picture may be limited to square form to increase the bandwidth available for the serial information signals. With either form of multiplexing, helical scan magnetic tape recording is preferably employed. Playback circuits effect separation of picture from information signals through a discriminator for time multiplexed signals and through a filter for frequency multiplexed signals. Provision is made for insertion of special lines in the television picture and for the retrieval thereof on playback.
