<p>PURPOSE:To efficiently attain encoding at the time of operating a hierarchical encoding by providing at least more than two memories which store a predicted learning result. CONSTITUTION:Total ten picture element template is formed of a six picture element input 301 of a high resolution and a four picture element input 302 of a low resolution. In a multiplexer 303, an A side is selected during the operation of an encoding/decoding, and the template is outputted to a 306. In predicted state memories 307-310, a bidirectional bus is realized so that an MPS (prior symbol in an arithmetic encoding) (311) 1 bit and a present predicted state (312) 7 bit can be outputted at first, and then updated after the encoding/ decoding of one picture element is ended. A memory control part 317 controls the initialization or updating timing of the predicted state memories 307-310. Therefore, an initializing time can be shortened by simultaneously clearing the predicted state memories 307-310 of four banks.</p> |
