    • A video signal processing apparatus which receives a digital video signal having arrangement of pixels frame by frame as an input, performs compressively coding to the digital video signal, and reproduces compressively coded data, comprises blocking unit for performing block dividing process by dividing the video signal of one frame into first blocks having a first format and second blocks having a second format which is different from the first format, performing block changing process by changing the format of the second blocks to the first format, and producing a converted video signal composed of plural blocks having the first format; and compressive coding unit for performing compressive coding including discrete cosine transform process to the converted video signal produced by the blocking unit.
    • 视频信号处理装置,其以帧为单位接收具有像素排列的数字视频信号作为输入,对数字视频信号进行压缩编码,并再现压缩编码数据,包括:通过划分视频信号进行块分割处理的块单元 一帧转换成具有第一格式的第一块和具有与第一格式不同的第二格式的第二块,通过将第二块的格式改变为第一格式来执行块改变处理,并且产生由 具有第一格式的多个块; 以及压缩编码单元,用于对由所述阻挡单元产生的转换视频信号执行包括离散余弦变换处理的压缩编码。
