Abstract
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.
