  • Patent number: 6574418
    Abstract: To perform non-normal speed reproduction without preventing a user from understanding of the program content. The audio data which has been blocked into blocks of a predetermined time unit is stored in a buffer. Blocks having the level equal to or lower than a predetermined threshold value are treated as silence data, and the block numbers are stored in a silence pointer buffer. A read out address generating unit does not read out blocks which is stored in the silence pointer buffer when the read out address buffer reads out audio data blocks from the buffer. The audio data from which silence data blocks have been excluded is subjected to connection processing in a waveform connection processing unit so that noise is not generated. A skip pattern generating unit controls a video data processing unit so that the video data is sent out with skipping some video data corresponding to blocks treated as silence block stored in the silence pointer buffer.

  • Patent number: 6542695
    Abstract: A video signal recording/reproduction apparatus utilizes time division writing and reading to implement simultaneous recording and reproduction of different video signals to and from a common recording medium. In one operating mode, a first video signal being recorded and a second video signal being reproduced are simultaneously displayed in separate windows on a display. In other operating modes, two or more video signals are simultaneously recorded or reproduced to/from a common recording medium, and simultaneously displayed in separate windows.

  • Patent number: 6529679
    Abstract: The invention provides an information processing apparatus and method as well as a providing medium by which a period for reproduction of reproduction data at fixed intervals can be calculated to reproduce the reproduction data in a fixed period. First, a TOC of reproduction data is read out and a frame number of the reproduction data is calculated. Then, a readout time within which the reproduction data for one frame are read out from a recording medium is calculated. Thereafter, a sum total of reading position movement times when the reproduction data for L frames are read out is calculated. Then, a sum total of reproduction processing waiting times when the reproduction data for the L frames are read out is calculated. Then, the sum totals of the readout times, reading position movement times and reproduction processing waiting times are added to calculate a total time.

  • Publication number: 20020006270
    Abstract: A recording/reproducing device has an NTSC decoder which receives a video signal and outputs a video signal, an MPEG audio encoder which receives an audio signal and outputs an audio signal, and a synchronous control circuit which detects a synchronizing signal from the video signal input to the NTSC decoder and uses that signal to generate an output synchronizing signal that is different from the input synchronizing signal. The output synchronizing signal is used to output the video signal from the NTSC decoder. In the recording/reproducing device, the NTSC decoder and the MPEG audio encoder provide a delay to the input video signal and audio signal, respectively, and output the video signal and audio signal in accordance with the output synchronizing signal generated by the synchronous control circuit.
