Dynamic media labeling method, device and system as well as encoding structure based on TS stream encapsulation

The invention discloses a dynamic media labeling method, device and system as well as an encoding structure based on TS stream encapsulation. The dynamic media labeling method based on TS stream encapsulation comprises the following steps: adding a DMT (Dynamic Media Table) information table packet during encoding; wherein the DMT information table packet carries a message for representing an identification number including DMT, a data label for a data type in TS stream and the DMT; executing a DMT information loading task; and encoding dynamic TS streaming media for which DMT information loading is completed to form and send a dynamic TS packet. Through implementation of the dynamic media labeling method, device and system as well as an encoding structure, the problem that program information cannot be dynamically labeled is solved, and the information interaction and rapid popularization of dynamic programs are facilitated. 本发明公开了种基于TS流封装的动态媒体标示方法、装置、编码结构以及系统，该基于TS流封装的动态媒体标示方法包括：在编码时加入DMT信息表包；其中，DMT信息表携带用于表
