  • Matching circuitry for use with a radar station and a television magnetoscope
    Patent number: 4238794
    Abstract: The invention provides matching circuitry for use with a radar station and television magnetoscope, the latter having a video channel and an audio channel. The matching circuitry enables the audio channel of the magnetoscope to be used for information concerning the instantaneous position of the antenna of the radar station, and the video channel for video and synchronizing signals. An oscillator isused to supply artificial frame pulses to a control track of the video channel of the magnetoscope. The recordings of these pulses are used to synchronize the video reading head of the magnetoscope when the information is being retrieved or reproduced from the magnetoscope.
