摘要： A coding apparatus 100 that generates coded data by coding inputted data in a predetermined unit basis, maps one or more units of the coded data onto a packet of fixed length and output the packet including: a storage unit 103 that stores the coded data and outputs the data size of the stored coded data; a packetization unit 104 that maps the coded data stored in the storage unit 103 onto the packet and outputs the header size assigned to the one or more units of the coded data and the payload size of the packet; a control unit 107 that generates the control information based on the data size of the outputted coded data, the header size and the payload size and outputs the control information; and a coding unit 102 that generates the coded data by calculating an outer candidate value that makes the data size of the coded data to be mapped onto the packet an integral multiple of the payload size of the packet based on the outputted control information and coding the predetermined units of inputted data up to the outer candidate value.
摘要翻译：编码装置100，通过以预定单位为基础编码输入数据来生成编码数据，将编码数据的一个或多个单位映射到固定长度的分组上，并输出分组，包括：存储单元103，其存储编码数据和输出存储的编码数据的数据大小; 分组单元104，将存储在存储单元103中的编码数据映射到分组上，并输出分配给编码数据的一个或多个单元的报头大小和分组的有效载荷大小; 控制单元107，其基于输出的编码数据的数据大小，报头大小和有效载荷大小生成控制信息，并输出控制信息; 以及编码单元102，通过基于输出的控制信息，计算使要被映射到分组的编码数据的数据大小成为分组的有效载荷大小的整数倍的外部候选值，并对预定单位的输入数据直到外部候选值。
