  • RGB display of a transcoded serial digital signal
    Patent number: 5311295
    Abstract: An RGB display of a transcoded serial digital video signal is produced by converting the serial digital video signal to a parallel digital video signal, separating the digital luminance component signal and the two digital difference component signals from the parallel digital video signal, converting the digital luminance and color difference component signals into analog encoded color component signals, transcoding the analog encoded color component signals into RGB component signals, and routing the RGB component signals to a waveform display device. The RGB component signals also are routed to a gamut detection circuit where each component is compared with nominal plus and minus limit levels to determine if there is a gamut error.
