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 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： 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.
