    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.

    摘要翻译： 本发明提供一种数据传输方法和数据接收方法，其使音频数据能够以简单的配置令人满意地复用到视频数据中并使用DVI标准电缆等传输。 从数据发送端，发送音频数据叠加在使用视频空白同步信号和像素时钟生成的叠加定时的视频消隐间隔的叠加视频/音频数据信号， 通过DVI电缆连接到数据接收端，以及视频空白同步信号和像素时钟。 在数据接收端，使用发送的视频空白同步信号和像素时钟生成用于从叠加的视频/音频数据信号中提取音频数据的定时信号，叠加的视频/音频数据信号被分成 使用所生成的定时信号的视频数据和音频数据以及数字音频数据使用通过划分像素时钟的频率而产生的音频时钟被转换为模拟音频信号。

    摘要： To reduce the amount of operation in a filter circuit when recording and reproducing signals at sampling frequencies that vary from channel to channel, in reproduction by using multiple speakers of DVD audio.
    Upsampling information generation means 6 are provided for obtaining upsampling information indicating whether or not a sample is a sample before upsampling performed by the upsampling means 2a and 2b, an upsampled signal is filtered by a half band filter circuit 3, the filtered signal is subjected to Lossless compression, and the Lossless-compressed data is recorded on a recording medium 8.
