ABSTRACT:
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.
