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.

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.

摘要翻译： 执行非正常速度再现，而不阻止用户理解节目内容。 已经被阻塞成预定时间单位的块的音频数据被存储在缓冲器中。 具有等于​​或低于预定阈值的块被视为静音数据，并且块号被存储在静默指针缓冲器中。 当读出地址缓冲器从缓冲器读出音频数据块时，读出地址产生单元不读取存储在静默指针缓冲器中的块。 将排除了静音数据块的音频数据在波形连接处理单元中进行连接处理，从而不产生噪声。 跳过图案生成单元控制视频数据处理单元，从而通过跳过对应于存储在静音指针缓冲器中的作为静音块的块的一些视频数据而发送视频数据。

摘要： 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.

摘要： Images of reproduced video data of plural channels are displayed on main small screens arrayed in a central horizontal row on an index picture. Time-serially anterior images of reproduced video data are displayed on two upper small screens above the main small screens, while time-serially posterior images of reproduced video data are displayed on two lower small screens below the main small screens. In a forward reproduction mode, the images displayed on the respective small screens are altered, with a lapse of time, to the lower adjacent images while being cross faded. And in a reverse reproduction mode, the images are altered, with a lapse of time, to the upper adjacent images while being cross faded. A normal reproducing operation is started from a desired image when the main small screen, where the desired image is being displayed, is selected by means of a cursor. Thus, any image of video data can be indexed efficiently.

摘要： A method and an apparatus for recording and reproducing a TV broadcasting signal includes a CM detecting unit, a write data processing circuit, a recording system control circuit, and a recording medium. The CM detecting unit operates to detect if a TV broadcasting signal composed of a RF signal inputted through an antenna is now a CM. The write data processing circuit operates to generate CM information accompanied with the CM detected by the CM detecting unit. The recording system control circuit operates to record on the recording medium the CM information generated by the write data processing circuit together with a video signal and an audio signal.
