In addition to the composite output signal, there is the facility to output S-VHS Y/C video, YUV or RGB video. The Y/C, YUV or RGB format is simultaneously available at the analog outputs with the composite video signal. Each analog output generates a standard video-level signal into a doubly terminated 75 Ω load.
