ABSTRACT:
The multichannel video processing unit of the invention includes: a decoding section for sequentially selecting a bit stream from a plurality of bit streams each including encoded data of an image of one channel, decoding the selected bit stream by one frame each, and outputting decoded data; a vertical filtering section for sequentially selecting a channel from a plurality of channels corresponding to the decoded images, performing vertical processing for the decoded data corresponding to the selected channel, and outputting vertically-processed data; a horizontal filtering section for sequentially selecting a channel according to the position at which the image is to be displayed, performing horizontal processing for the vertically-processed data corresponding to the selected channel, and outputting horizontally-processed data; and an output processing section for generating a video signal for display of images of a plurality of channels by synthesizing the horizontally-processed data and outputting the generated signal.
