Description

Technical field

[0001] The present invention relates to a method and device for storing and playing back Moving Picture Experts Group 2 (MPEG-2) Transport Stream (TS); more specifically, it relates to a method and device for storing and playing back a transport stream (TS) based on the International Organization for Standardization (ISO) Method and equipment for MPEG-2TS media file format.

[0002] This work is supported by the IT R&D project of MIC / IITA [2006-S-082-02, "Development of Digital Multimedia Broadcasting Technology for Personalized Broadcasting"]. Background technique

[0003] Since there is no standard method for storing MPEG-2 Transport Stream (TS) and Digital Multimedia Broadcasting (DMB) TS, service providers or terminal manufacturers each adopt a different storage method or use a method of storing the transmitted MPEG-2 TS as it is .

[0004] If each terminal manufacturer adopts an independent storage method, in order to prevent illegal dissemination and storage o...
