摘要： An apparatus and method for recording and reproducing a sound (i.e. audio) signal corresponding to a video signal at a higher than normal speed. The method delimits a sound signal reproduced at a recording medium at a speed higher than a normal speed into successive processing unit periods. For each processing unit period, sound absence portion(s) of the reproduced sound signal are deleted (or partially deleted) within a range corresponding to a normal speed reproduction. Sound presence portions preceding and following the deleted absence portions are joined or compressed to produce a recognizable sound signal.

摘要： 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. Finally, a reproduction data transfer period is calculated based on the total time, and reproduction of the reproduction data is performed at time intervals corresponding to the reproduction data transfer period.

摘要： A commercial candidate section detector detects a commercial candidate section on the basis of a quiet section and a scene change point. A commercial characteristic quantity detector judges whether the commercial candidate section has various characteristics of commercials, and adds a predetermined value to an commercial characteristic value on the basis of the judgment result. The commercial characteristic quantity detector compares the final commercial characteristic value with a predetermined threshold value, and judges on the basis of the comparison result whether the commercial candidate section is a commercial section.

摘要： 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.

摘要： By reducing the number of seek operations in an operation to play back a signal from a recording medium, the amount of data temporarily stored in a read buffer memory employed in a signal recording/playback apparatus is large enough to be output as a playback signal during a seek operation, allowing a continuous playback operation to be carried out. In order to reduce the number of seek operations, a signal is always recorded onto the recording medium in continuous free areas each having a size equal to or larger than a predetermined recording/playback time length which is typically set at 1 minute. If it is necessary to insert an additional signal having a length smaller than the predetermined recording/playback time length into a point of insertion in an area already occupied by an existing signal, a continuous free area with a size equal to or larger than the predetermined recording/playback time length is newly allocated to the additional signal. The additional signal is then recorded in the free area instead of being inserted into the point of insertion. Since the free area is larger in size than the length of the additional signal, the rest of the free area is filled up with a portion of the existing signal adjacent to the point of insertion.
