摘要： 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.

摘要： 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.

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.
