ABSTRACT:
An image code transform system for arranging and composing a plurality of small screens of moving images to a large screen image, compressing and encoding the large screen image to generate a large screen compressed/coded data sequence, and extracting small screen compressed/coded data sequences of the plurality of small screens of moving images from the large screen compressed/coded data sequence. The system includes a multiplexer for re-arranging frames of the plurality of small screen moving images at an identical time to generate a composite frame and generating a large screen moving image signal of the composite frame; a compressor/encoder for compressing and encoding the large screen moving image signal on a block basis to generate a large screen compressed/coded data sequence signal and for outputting the large screen compressed/coded data sequence signal, the block being obtained by dividing the large screen moving image signal; and a separator/converter for separating and converting a plurality of small screen compressed signals corresponding to the plurality of small screens directly from the large screen compressed/coded data sequence signal.
