DECODING SYSTEM FOR DECODING MULTIMEDIA FILES, SYSTEM FOR ENCODING A MULTIMEDIA FILE, AND MULTIMEDIA FILE

摘要

In a decoding system for multimedia files, a processor extracts information from a multimedia file, which includes a plurality of chunks for carrying information, including video chunks (262) and audio chunks (264), which are portions of at least one audio track. The video chunks (262) are portions of at least one video track comprising a series of encoded video frames including at least encoded video frames 1 through N, said video chunks (262) including at least video chunks 1 through N. The processor further accesses information from the multimedia file by decoding frame N using video chunk N together with video chunks 1 through N-1; and when video chunk N is a marker chunk, video chunks 1 through N-1 contain sufficient information to generate frame N and frame N is decoded using video chunks 1 through N-1.
