Abstract
Methods to produce media data ensure a method for media data transmitting, and a method for media data processing, and the synchronization and correct processing and transmission of bitstreams on the basis of dependency relation between video layer bitstream and library layer bitstream, and correct bitstream is highly efficiently provided to a decoder. With methods for reference picture request processing and reference picture specifying, a current picture includes a library picture set in which the library picture does not belong to the random access segment to which the current picture belongs and the previously most adjacent random access segment, and correct decoding of the current picture is ensured and repeated downloading of library pictures is avoided, thus ensuring the correct decoding and highly efficient transmission of a bitstream produced by library-based video coding method, and increasing transmission efficiency and storage efficiency.
