ABSTRACT:
A time code or other digital code is inserted into a video signal by modulating the video signal itself or the signal's radio frequency (RF) carrier. This allows the code to be recorded concurrently with recording of the video signal, thereby obviating the need for a specially adapted recording apparatus. Furthermore, since the code is embedded in the recorded video signal, the encoded information may be retrieved from the video signal in a unit that is external to the playback apparatus. In combination with a conventional video cassette recorder (VCR), the video signal that is tuned to by the VCR is processed to extract raster synchronization signals. A modulator inserted ahead of the RF input to the VCR modulates the RF carrier in response to the digital code. Feedback of the tuned video signal insures proper synchronization of the broadband RF modulation so that the digital code is inserted into a non-viewable portion of the recorded video signal.
