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.
摘要(中):
帧编码单元(13)根据运动图像信号Vin生成个别图像信号信息,并且输出作为对每个帧的图像信号信息进行编码的结果而获得的数值的帧编码值InfVal_F。 可变长度编码单元(16)将帧编码值InfVal_F分解为作为编码的基本单位的单位帧编码值Val_F,将单位帧编码值Val_F转换为仅使用单个编码表(16a)的帧编码字Code_F, 并通过组合转换的帧码字Code_F来构造帧流。 复用单元(17)复用通过与传统方法等效的方法构造的标题流和帧流,并构造图像编码信号Str。
