    摘要： When, through a multi-speaker of a DVD audio system, signals are recorded/reproduced using a sampling frequency different for every channel, the quantity of calculation of a filter circuit is reduced. Up-sampling information about whether or not the sampling is carried out before the up-sampling by up-sampling means (2a, 2b) is acquired by up-sampling information detecting means (6). The signal up-sampled is filtered by a halfband filter circuit (3), subjected to loss-less compression, and recorded on a recording medium (8).

    摘要： The present invention is relative to a video signal transmitting/receiving system in which digital video signals are transmitted from a transmitter (30) to a receiver (50) using a line (9) as a transmission channel. The transmitter (30) converts the video signals to be transmitted to a bit string longer in data length than a pixel making up the video signals, allocates a plural number of the bit strings to a blanking period during which pixel data in the pixel string is not transmitted and, using these bit strings, transmits the same superposed data a plural number of times. The receiver (50) extracts the specified bit strings indicating the blanking period from the received data and performs majority processing on the results of demodulation of the extracted bit strings to decide on output data. This reduces errors in reception of supplementary data to simplify the circuit structure as well as to ameliorate the error rate.

    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.
