A video display unit according to the present invention is provided with a multipurpose arithmetic unit for generating display data by carrying out at least one operation within one period of the pixel clock and an instruction sequencer for describing as instructions the display data and the operational contents to be inputted to this, and by implementing the described instructions while synchronizing to the display clock, picture up/down scaling processes as well as a blending process with the OSD are realized. Thereby, it is not necessary to provide a dedicated circuit for each of required specifications such as in a conventional unit, and by rewriting instructions within the instruction sequencer, it is possible to cope with a plurality of display specifications.

Video display unit and program recording medium

A video signal processing device comprising an operating element array for processing video signals according to commands given from the outside, memories for temporarily storing the video signals according to commands given from the outside, and a network,for connecting the operating element array and the storage units according to commands given from the outside, thereby making it possible to switch ways of processing digitized video signals according to commands from the outside.

Video signal processing device

A multi-standard television receiver in accordance with the present invention includes a plurality of video signal processing blocks having tristate functions at their output terminals, at least one memory block used in common for a plurality of video signal processing blocks and a video signal processing selection means for selecting one of the video signal processing blocks and independently controlling the output terminals of the video signal processing blocks using elements having a tristate function and can reduce power consumption by working only a selected video signal processing block and stopping the other video signal processing blocks. Further, using elements having a tristate function, possibility of element breakdown at selection and control of the elements can be removed.
