ABSTRACT:
A portable video camera and recording apparatus is comprised of a video camera section and a recording section. The video camera section is comprised of a CCD, analogue-to-digital converters for converting signals from the CCD into digital form. The digital signals are then processed, converted into analogue form, processed in analog form, and then output as the composite video signal. A digital luminance signal and either a digital composite color signal or a plurality of digital color difference signals are received as inputs into the recording section. If the digital composite color signal is received, then the signals are time-base-compressed, converted into analogue form, the composite color signal is frequency converted and filtered and the luminance signal is frequency modulated and filtered. Next, the signals are added together and recorded onto a recording medium. If the digital color difference signals are received, the digital color difference signals are multiplexed together, converted into analogue form, frequency modulated, filtered and then recorded onto one track on the recording medium. The digital luminance signal is time-base-compressed, converted into analogue form, frequency modulated, filtered, and then recorded onto a second track on the recording medium.
