  • Publication number: 20060110137
    Abstract: An object of the present invention is to create a status where the copyright protection and the improvement in userfriendliness can be concurrently realized. This can be realized by enabling a user to select the way how the digital video and audio data is made unavailable for playback. More specifically, whether the data is to be made unavailable for playback in an unrecoverable manner or in a recoverable manner may be determined depending on the deterioration level in data rate that is made at the time when the recorded digital video and audio data with which a copy-once signal is multiplexed is transmitted to another recording medium.

  • Publication number: 20050232597
    Abstract: A video recording apparatus provides a slow motion effect or a quick motion effect by digitally converting the frame-rate instead of by changing the playback speed of the film, and using few recording media without requiring any special device at playing. A picture encoding part encodes only valid frames by changing a rate-controlling method so that a predetermined playing frame-rate is obtained at a standard data-rate at playing. And a TS multiplexing part multiplexes by converting a frequency of a standard STC clock by only a ratio of valid frame-rate and playing frame-rate, and generating values for PCR, PTS, and DTS.
