    摘要： Provided is an AV system which comprises a display unit and a plurality of video devices connect to the display unit, and which can perform remote control operation of the video devices with aiming the remote controller at the display.
    On a display (100) end, maker codes and device codes are read from all STBs (110)~(112) connected to the display (100) to create a connected-device list table. When a user presses a button on a remote controller, the display receives a remote control code outputted from the remote controller, searches the connected-device list table for a maker code and a device code that match the maker code and the device code included in the remote control code, controls a selector (105) so that a reception interface that is connected to an STB whose maker code and device code match those included in the remote control code is connected to a display section (102), thereby to display and reproduce AV data transferred from the STB on the display section (102).

    摘要： This invention provides a data transmission method and a data receiving method which enable audio data to be multiplexed into video data and be transmitted using a DVI standard cable or the like satisfactorily with a simple configuration.
    From a data transmitting end, a superimposed video/audio data signal in which audio data are superimposed over a video blanking interval of video data in superimposition timing that is generated using a video blank sync signal and a pixel clock, are transmitted to a data receiving end through the DVI cable, together with the video blank sync signal and the pixel clock.
    On the data receiving end, a timing signal for extracting the audio data from the superimposed video/audio data signal is generated using the transmitted video blank sync signal and pixel clock, and the superimposed video/audio data signal is separated into video data and audio data using the generated timing signal, as well as the digital audio data are converted into an analog audio signal using an audio clock that is generated by dividing the frequency of the pixel clock.

    摘要： In a signal transmitter and a signal receiver according to the present invention, a multiplexing part (102) multiplexes a video signal and a time-base-compressed audio signal on the basis of a multiplexing control signal to transmit the multiplexed signal through a data line (106) in the signal transmitter, and a demultiplexing part (103) demultiplexes a video/audio multiplexed signal received through the data line (106) into the original video signal and audio signal by a demultiplexing control signal in the signal receiver. Further, a horizontal synchronizing signal or vertical synchronizing signal of the video signal is employed as the multiplexing control signal and the demultiplexing control signal, and the audio signal is time-base-compressed at the transmitting end, to multiplex the audio signal in a blank of the video signal, and the multiplexed audio signal is time-base decompressed at the receiving end.
    According to the so-configured signal transmitter and signal receiver, it is possible to realize a signal transmission system compliant with the DVI standard, in which the audio signal as well as the video signal can be transmitted.
