摘要： A device enabling simultaneous recording and playback allows commercials to retain their advertisement function even if the commercials are skipped over during a playback process. By digital watermarking, CM-substitute data is embedded in program data among video signals broadcasted from a broadcast station. CM-substitute data is to present information such as a particular sponsor name and commodity name on display. The video recording/playback device includes a randomly accessible storage unit and has a simultaneous recording/playback capability. If commercial video is skipped over and is not rendered by playback, the CM-substitute information is superimposed on the rendered video of the program associated with the commercial. Thus, the commercial advertisement function can be retained.

摘要： A picture display technique carries out an adjustment of image quality of an inputted picture signal in response to a type of the inputted picture signal, e.g., a type of a first picture signal into which a second picture signal, having fewer scanning lines than that of the first picture signal, is converted, and an original type of the first picture signal, and then displays a picture of an adjusted picture signal on a display device. Further, the adjustment of the picture quality may include at least one of hue correction of the inputted picture signal in a certain hue range and chroma correction of the inputted picture signal in a certain chroma range. The adjustment of the picture quality may also include a contour correction of the inputted picture signal.

摘要： An RGB signal from an input terminal is supplied to a triple over-sampling/sub-pixel control processing unit and a brightness signal generating circuit in which a brightness signal is generated. A brightness edge detection/judgment unit detects an edge from this brightness signal, judges the kind of the edge, fetches a coefficient select signal corresponding to the judgment result from a memory and supplies the signal to the control processing unit. A tap coefficient corresponding to this coefficient select signal is set in the control processing unit and a triple over-sampling processing is executed for each of RGB. For edge parts, R and B sub-pixels the timings of which are displaced by ±⅓ pixel from the input R and B sub-pixels and the pixel gravitys of which are displaced by ±⅓ or ±⅛ pixel in accordance with the kind of the edge are generated.
