ANIMATION PICTURE TRANSMISSION AND RECEPTION SYSTEM

摘要

PURPOSE:To reduce the transmission rate without decreasing the resolution on a received pattern by dividing all picture element number into plural groups, rewriting only one picture element of each group at one frame rewrite and using information of the preceding frame for other picture element. CONSTITUTION:The picture is inputted by a sensor built in a TV camera 1 while being decomposed into a picture element and subjected to A/D conversion 2. An information selecting section 12 selects only the information to be transmitted according to the predetermined order among all picture element signals and the information is stored in a transmission frame 3. The information of the memory 3 is transmitted via a high efficiency coder 4 and a transmission processing section 5. Then a reception section applies reception processing (7) to the transmitted signal, decodes and transmits it to an information sharing section 13, which shares this signals to a coordinate corresponding to a reception frame memory 9. Then the memory 9 has a storage capacity to express all the picture element information and the memory capacity for the number of groups formed dividedly is enough for the memory 3. Its output is subjected to D/A conversion and displayed (11).
