Abstract: A method for supporting random access of MPEG data comprises the steps of: obtaining at least one access unit including media data, which is coded through a process including capsulation and packetization; generating at least one media processing unit (MPU) by grouping the at least one access unit; determining an initialization flag which indicates whether the at least one access unit in the at least one MPU includes all data required for initializing a decoding process; and inserting the initialization flag into at least one header of the MPU.
Abstract translation: 一种用于支持MPEG数据的随机存取的方法包括以下步骤：获得包括媒体数据的至少一个接入单元，该媒体数据通过包括封装和打包的过程进行编码; 通过对所述至少一个访问单元进行分组来生成至少一个媒体处理单元（MPU）; 确定指示所述至少一个MPU中的至少一个接入单元是否包括初始化解码过程所需的全部数据的初始化标志; 以及将所述初始化标志插入所述MPU的至少一个头部。
