Industrial applicability

The present disclosure relates to a media information encapsulation/parsing technology in the field of communication technologies. Since a package file adds logical processing information to each piece of media information segments, a package file can satisfy the needs of a plurality of different users; When adding logic, it only needs to be added at the time of encapsulation without re-publishing the program; thus, the workload of audio and video encapsulation/parsing can be reduced, and the processing efficiency is improved.

The above description is only for the preferred embodiments of the present disclosure, and is not intended to limit the scope of the disclosure.
