摘要

PROBLEM TO BE SOLVED: To obtain a device suitable for software processing by providing an information bit input means that divides information bits in the unit of 2's power bits and receives the result and a matrix arithmetic means that executes sequentially matrix arithmetic operations. ;SOLUTION: A video data input section 101 receives video data in the unit of 8-bit, and a memory 103 stores a BCH arithmetic table. An H.261 coding section 110 applies compression to video data in compliance with the ITU-T recommendations H.261 and provides an output of compressed video data to a BCH coding section 100 coding the data into a BCH code being one of cyclic codes. A line section 120 applies multiplexing to a video frame outputted from the BCH coding section 100 according to a frame configuration of the ITU-T recommendations H.221 and sends a multiplexing frame to the line. As the operation, at first a matrix arithmetic section 102 initializes contents of 18-bit corresponding to each register value to all zero.;COPYRIGHT: (C)1997,JPO
