    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: As shown in figure 7, a data receiver receives video data and audio data together with a frequency division parameter N that depends on the pixel clock of the video data and the sampling frequency of the audio data, and a count value CTS that is obtained by counting the period of the audio clock that has been subjected to frequency division by the frequency division parameter N, with the pixel clock, which are transmitted from a data transmitter, and subjects the pixel clock to frequency division by the count value CTS, phase-control the divided clock (s501) in accordance with a phase comparison clock (s505) that is obtained by dividing an audio clock (s403) oscillated from a VCO (504) by the frequency division parameter N, thereby generating an audio clock (s403).
    Accordingly, the data transmitter and the data receiver can satisfactorily implement multiplexing of audio data and video data, and transmission of the multiplexed data using an existing DVI cable, with a simple structure.

    摘要: A minimum difference from the predictive loop outputs for each block in a predetermined length of time to delete a run common to the blocks and subjects the shifted up data to the Huffman conversion. Thus, the source data of a 96 kHz/24 bits/6 ch format (13.824 MBps) can be compressed at a compression ratio of 0.7 so that the data rate is not greater than 9.6 Mbps determined by the DVD format. Similarly, mode of 192 kHz/24 bits/2 ch format and the like can be realized. A large amount of the linear PCM super-audio data are compressed can be recorded and reproduced in the DVD format, and the recording time is increased.

    摘要: A bandpass filter (200) bandpass-filters an inputted signal X to pass therethrough a partial band of a band of the inputted signal X, and a level correlated white noise generator circuit (300) generates a white noise signal having a level changing according to a level of the inputted signal (X) and correlated to the inputted signal (X). A signal processing circuit (400) executes a signal processing that includes a predetermined bandpass filtering processing, an echo adding processing, and a level adjustment processing, and that multiplies the inputted white noise signal by a predetermined transfer function, and outputs a processed white noise signal to an adder (800). The adder (800) adds up the white noise signal from the signal processing circuit (400) and the inputted signal X, and outputs a band-extended signal having an addition result, as an outputted signal (W).
