    Abstract: When an erasable region among recorded regions is selected, additional information (time information and content information) corresponding to a recording region is obtained. The elapsed time is calculated from the time information and present time information. As reference information, preserving period information of every content information is held and whether it is erasable or not is determined on the basis of the elapsed time and the preserving period information. With respect to N recorded regions, whether it is erasable or not is sequentially decided. The recorded region corresponding to the longest elapsed time among the erasable recorded regions is decided as a recording region. The recording process is executed to the decided recording region.

    Abstract: A recording apparatus configured to receive analog video and audio signals, digitize and compress the same, and record the compressed audio and video signals on a digital recording medium such as an optical disk. As the audio and video signals are received and recorded, time segments of the audio signals are analyzed for certain features such as whether the time segment corresponds to instrumental music, vocal music or conversational speech. A table of contents is then generated corresponding to the feature analysis and digitally stored on the storage medium. As a result, the recorded audio is characterized over time, e.g., on a frame by frame basis. A high degree of versatility is thereby provided in the playback process, such as the ability to skip portions having certain audio types or to quickly scroll to desired portions of the recorded audio programs. Reproducing apparatuses enable the user to selectively reproduce segments of the recorded audio and video.

    Abstract: The method and apparatus concerns recording and reproducing a TV broadcasting signal including a commercial message (CM). The apparatus comprises a CM detecting unit (12), a write data processing circuit (9), a recording system control circuit (10), and a recording medium (11). The CM detecting unit (12) operates to detect if a TV broadcast signal inputted through an antenna (2) contains a CM. The write data processing circuit (9) operates to generate CM information accompanied with the CM detected by the CM detecting unit. The recording system control circuit (10) operates to record on the recording medium (11) the CM information generated by the write data processing circuit together with a video signal and an audio signal.

    Abstract: A signal reproducing apparatus is disclosed with which time is not required from a moment at which a user has started a reproducing operation to a moment at which the user is able to actually confirm required information. An audio-and-video-signal reproducing apparatus incorporates a head for recording an audio and video signal recorded on a recording medium; a RAM on which the audio and video signal read by the head is temporarily stored; and a control circuit having a control function for controlling the head to read the audio and video signal recorded on the recording medium and controlling writing of the audio and video signal temporarily stored in the RAM.
