    摘要: In a video audio processing device, a signal processing block (11, 12) includes an instruction memory (111, 121) and performs signal processing in accordance with a program loaded into the instruction memory. A main storage section (20) has a self-refresh function and is accessible from the signal processing block. An auxiliary storage section (30) stores the program for making the signal processing block perform the signal processing. Upon receipt of a standby instruction, a control section (15) performs control in such a manner as to transfer the program from the auxiliary storage section to the main storage section, and set self-refresh in the main storage section, and upon receipt of a return instruction, performs control in such a manner as to cancel the self-refresh in the main storage section, load the program from the main storage section to the instruction memory in the signal processing block, and activate the signal processing block.

    摘要: In a multi-format transport stream decoder that performs a desired process on first transport streams of different formats to generate a second transport stream, a process request information input unit (APR) is supplied with process target packet data (Pi) and process request information (ScW) indicative of process details. A stream identification information providing unit (TSRi) provides stream identification information (TSID). A packet data retaining and identifying unit (DBA) retains each pieces of first packet data (Pi), and compares the stream identification information (TSIDe) and packet data identification information (PIDe) of the first packet data (Pi) with the process request information (ScW) to determine whether the information is to be processed.

    摘要: A video memory stores a plurality of image data, and an attribute storage means stores image attributes indicating whether or not the respective image data require expansion of a luminance range. An image data conversion means receives an image data digital signal output from the video memory and an image attribute signal output from the attribute storage means. When the image attribute signal provides an instruction to expand the luminance range, the image data conversion means outputs, to a display unit, a display data analog signal representing a higher luminance value, as compared with the display data analog signal to be output therefrom when the image attribute signal provides no instruction to expand the luminance range.

    摘要: Two or more image data memories receive an image address signal and a image data signal. When the image address signal indicates writing of an image data and writing address, an image data stored at the writing address is specified by the image address signal. When the image address signal indicates reading an image data and reading address, an image data is read out from the reading address specified by the image address signal to be output. When the image address signal indicates writing of an image data and writing address, a first control data memory stores a process control data at the writing address specified by the image address signal, and sequentially outputs stored process control data as a process control data output signal. When the image address signal indicates writing a data into one of the image data memories, a second control data memory outputs a stored process control data, and stores a process control data when the image address signal indicates writing a data into the first control data memory. An image processor processes image data in accordance with the process control data output signal, and outputs a processed image data.
