摘要： In a data reproducing apparatus, the effective capture range is enlarged by controlling the capture range of the clock reproducing phase locked loop circuit based on the difference between a measured bit rate and a standard rate according to the operation mode. It is preferable to correct the bit rate additionally. Stable control may be performed even at the time of high speed searching accompanied by large mechanism load variations and under a transient state of mode transition, thus making it possible to read the data stably at all times.

摘要： A video signal and an audio signal are transmitted from a source device to a sink device in conformity with respective predetermined interfaces through respective transmission channels. The respective interfaces include bidirectional interface such as an HDMI and an IEEE1394. A controller acquires delay information (TLv) representing the total delay time of the devices connected to the transmission channels conforming to the bidirectional interface and corrects the difference in reproduction time between the video and audio signals by using the acquired delay information (TLv).

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： The present invention provides a recording and reproduction device capable of preventing content having details identical to the details of outputted content from being reproduced simultaneously with the outputted content, and allowing the content to be reproduced in high quality. A recording/reproduction device (110) includes a recording area (115), a communication processing unit (119) capable of outputting the related content having details identical to details of the content recorded in the recording area (115) into an external recording medium (160), and an encoding/decoding processing unit (117) capable of obtaining unique information of the external recording medium (160). The encoding/decoding processing unit (117) changes a state of content recorded in the recording area (115) into a state irreproducible unless using unique information of the content, when the related content is outputted to the external recording medium (160); then reproduces the content recorded in the recording area (115) using the unique information, when the encoding/decoding processing unit (117) obtains the unique information.

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： This invention relates to a time code recording and reproducing apparatus for recording and reproducing time codes corresponding to a digital signal. Time code converting means (100) converts a first time code into a second time code. A frame phase which occurs during the recording of input information is determined by frame timing generating means. A phase difference between a frame of the second time code and a recording frame is detected by phase difference detecting means (103). Phase difference correcting means (104) outputs a third time code on the basis of the detected phase difference. The input information is recorded together with the third time code. Thereby, the recording can be performed while the relation of the correspondence between the input information and the time code is held. In addition, the reproduction can be performed.
