摘要 |
A frame coding unit (13) generates individual picture signal information from a moving picture signal Vin, and outputs a frame code value InfVal_F which is a numeric value to be obtained as a result of coding picture signal information of each frame. A variable length coding unit (16) decomposes the frame code value InfVal_F into unit frame code values Val_F which are basic units of coding, converts the unit frame code values Val_F, into frame code words Code_F using only a single code table (16a), and constructs a frame stream by combining the converted frame code words Code_F. A multiplexing unit (17) multiplexes a header stream which is constructed through a method equivalent to a conventional method and the frame stream, and constructs a picture coded signal Str. <IMAGE> |
