Method of managing MPEG-4 object information in MPEG-2 transport stream
First Claim
1. A method for managing a motion picture expert group-4 (MPEG-4) object information in an MPEG-2 transport stream (TS), the method comprising the steps of:
- a) receiving an MPEG-4 SL (Sync Layer) to be transmitted as an MPEG-2 TS;
b) acquiring an object information from the MPEG-4 SL;
c) aligning the acquired object information corresponding to a program map table (PMT) of the MPEG-2 TS; and
d) creating an MPEG-2 TS which has the PMT corresponding to the object information.

Abstract
Disclosed is a method of managing a Motion Picture Expert Group-2 Transport Stream (MPEG-2 TS) in an object unit of an MPEG-4 by efficiently matching the MPEG-4 with the MPEG-2 TS, in order to broadcast an internet protocol (IP). The method manages MPEG-4 object information in an MPEG-2 TS status, by adding the object information to a program map table (PMT) in the course of converting an MPEG-4 data into an MPEG-2 TS. The method includes the steps of: a) receiving an MPEG-4 SL (Sync Layer) to be transmitted as an MPEG-2 TS; b) acquiring an object information from the MPEG-4 SL; c) aligning the acquired object information corresponding to a program map table (PMT) of the MPEG-2 TS; and d) creating an MPEG-2 TS which has the PMT corresponding to the object information.
