Abstract
A video apparatus for storing video images on a recording medium and replaying the stored images on a display includes a camera which converts light images into electrical video signals. A processor coupled to the camera converts the electronic video signals into a low bandwidth frequency modulated storage signal with the bandwidth substantially lower than in a standard television video signal. A recorder coupled to the processor stores the low bandwidth frequency modulated storage signal on an audio cassette, which has a standard speed allowing storage of an audio bandwidth signal. The recorder includes a drive for driving the cassette at higher than normal speed to increase the bandwidth storage capacity of the cassette. The video apparatus also includes a switch mechanism for switching the video apparatus from a record mode where video images are stored on the cassette to a playback mode where the stored images are read off the cassette and displayed on the video display. In playback mode, the low bandwidth video signal is converted to a higher frequency standard television bandwidth video signal for display.
