Abstract: A time code, found to be compatible with present video-tape, audio-cue systems at all tape handling speeds, is written once every second with a start pulse to identify every 1 s of information with a gated parity check. Once the signal has been decoded and channeled to the appropriate counter in forward or reverse, it may be read off the readout device. In the play mode, the counter reads off 1 s of information and preloads the counter before counting all following information from a division of the control track. The automatic search facility consists of a memory bank which is preloaded by a numeric keyboard. Shuttling is accomplished by an overload comparator which moves the machine past the desired point to the lower-count side, where the machine is put into play to run back up to the selected spot. There is also a comparator to give a relay closure on an exact tape count. This may be used to start another video- or audio-tape machine.
