Video and audio data transmitting apparatus, and video and audio data transmitting method |
摘要 |
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. The video and audio data transmitting apparatus that transmits the video and audio data recorded on the first recording medium to the second recording medium includes: a conversion processing unit 103 that converts the format of the video and audio data recorded on the first recording medium; a conversion detail judgment unit 101 that judges the conversion details concerning the video and audio data; and a playback disabling unit 106 that makes the video and audio data recorded on the first recording medium unavailable for playback in a recoverable manner based on the judgment made by the conversion detail judgment unit 101 . The video and audio data transmitting apparatus makes it possible to solve a conventional problem.
