Abstract
PURPOSE: To ensure the correction with inconspicuous boundary of blocks at the encoding or decoding time by carrying out the block encoding process through separation into the gradation component and the resolution component based on the picture elements around the boundary.
CONSTITUTION: TV camera 1 is connected to communication control unit 2, and the picture signal equivalent to one frame is converted 12 into the digital signal to be stored in picture memory 14. The digital signal is then converted 16 into the signal type and transmission velocity suited to transmission line 3 and then transmitted 17 after the block encoding process by taking in the signal equivalent to one frame into encoder circuit 15 with every block. At reception control unit 4, the block-encoded signals sent through transmission line 3 are received in sequence through signal input terminal 21 by the amount of one frame and then undergoes the decoding process through decoder circuit 23 after conversion 22 into the digital signals. The decoded signals are then stored in picture memory 24 and converted 25 into the analog video signals to be transmitted to display monitor 5 via the output terminal.
