  • Detection, correction and display of illegal color information in a digital video signal
    Patent number: 5373327
    Abstract: The present invention legalizes a video signal (e.g., 4:2:2 format) being processed in one format so that the video signal can be transformed to other formats (e.g., analog composite NTSC format). An editor can be notified of color legalities in a video signal. Further, each pixel of a video signal can be corrected to the nearest legal value by applying soft limits and gain slopes to a constant luminance color correction process. In accordance with the present invention, illegal colors of a video signal can be highlighted to provide an output drive for a video display which can be easily monitored by an editor. Alternate features of the present invention relate to error detecting and monitoring by assigning a specific, unique address to each video frame of a video signal. A further feature of the present invention relates to use of a pixel selecting means which receives 4:2:2 video data in either serial or parallel form.
