摘要： A method (400) and a system (100) for providing video signals to video displays includes the steps of receiving at least one input video signal (150), dithering the non-uniformity color correction (445), applying the non-uniformity color correction to the input video signal to generate a color corrected video signal (450), and increasing a frame rate of the color corrected video signal (120). Gamma correction (125) can be applied to the color correction. Generating a dithered non-uniformity color correction can include selecting from a data storage (115) a plurality of RGB correction matrices (300), measuring at least one brightness level of the input video signal, selecting for the picture level correction a first RGB correction matrix if the brightness is within a first range of values (425), a second RGB correction matrix if the brightness is within a second range of values (435), and interpolating (440) the plurality of RGB correction matrices if the brightness is within a third range of values.

摘要： Video signal processing apparatus includes a picture enhancement processor for processing a video signal to produce an enhanced video signal. The video signal includes a signal component representing video image data and another signal component representing non-image data such as vertical sync and a binary information component. The binary information component represents binary information that may occur, for example, during vertical blanking such as closed caption data, content advisory information (V-chip), or extended data services information. A control unit modifies the enhancement performed by the picture enhancement processor during intervals of the video signal that include non-image information. Modifying enhancement processing (e.g., reducing or disabling) during intervals that include the non-image information reduces degradation of the non-image information caused by the enhancement processing.

摘要： A digital video system includes a sample rate converter and an inverse-sample rate converter. The sample rate converter converts video data from a non-orthogonal pixel domain to an orthogonal pixel domain. The inverse-sample rate converter converts the video data from the orthogonal pixel domain to the non-orthogonal pixel domain. The inverse sample rate converter utilizes a timing signal generated by the sample rate converter when converting the video data from the orthogonal pixel domain to the non-orthogonal pixel domain.
