<p>The present invention discloses a method for generating media information, a terminal, a server, and an adaptive streaming system. Media code streams of m types of code rate, which are generated by an AHS system, are divided into h groups, and tracing codes are separately embedded into code stream segments of each group; the tracing codes embedded into the code stream segments, and code stream group information are stored in a media presentation description file MPD file; and in a downloading process of a terminal, tracing of an end user that downloads media data is implemented by using a tracing code. Media information that carries a tracing code can be generated in the foregoing process; that is, based on the foregoing process, media information that supports pirate tracing can be generated, and a problem of pirate tracing in an AHS service can be implemented. In addition, a server end does not need to generate multiple backups of a media file, and an objective of reducing memory space consumption is implemented.</p> |
