Problems solved by technology

Since DMB AF supports compatibility between stored broadcast content files or stores AV data by elementary stream unit, DMB AF cannot be used to store MPEG-2TS, which is commonly used as a file format for distributing terrestrial DMB content

Embodiment Construction

[0029] Through the following description of the embodiments with reference to the accompanying drawings, the advantages, features, and various aspects of the present invention will become clear, and will be described below.

[0030] figure 1 It is a block diagram showing a terrestrial digital multimedia broadcasting (DMB) terminal according to an embodiment of the present invention. Such as figure 1 As shown, the terrestrial DMB terminal 100 includes a signal receiver 102, a signal processor 104, an audio video (AV) decoder 106, an AV output unit 108, and a file storage 110.

[0031] The signal receiver 102 receives and processes terrestrial DMB signals, and outputs a moving picture experts group (MPEG)-2 transport stream (TS). The signal processor 104 extracts time information, position information, size information, and PMT related information from the MPEG-2 TS output by the signal receiver 101 as sample information. The file storage 110 stores the MPEG-2 TS output from the sig...

Abstract

Provided are a method and apparatus for storing and playing back an MPEG-2 TS based on an ISO-based media file format. The method includes: storing a target MPEG- 2 TS in an mdat box of the ISO-basedmedia file format; and dividing the MPEG-2 TS by samples through time information, location information, size information, and Program Map Table (PMT) related information for random access and describing the divided samples in an moov box of the ISO-based media file format.

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...
