摘要： An image processing apparatus prevents the inappropriate application of error diffusion and adaptively applies palette conversion functions according to the properties of the source. A processing subsystem performs various processing with respect to an original video source. A palette converter converts the palette bit depth, having modifiable palette conversion functions for creating the illusion of expressing the pre-conversion palette tones in the post-conversion image. A controller turns on the palette converter, turns off the palette converter, or modifies the palette conversion functions thereof, in accordance with at least original source information and system-wide settings information.

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。
