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.

Claims

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.

2. The method as claimed in claim 1, wherein, in step c), the acquired object information is aligned corresponding to a user private stream ID in the PMT of the MPEG-2 TS.

3. The method as claimed in claim 2, wherein the user private stream ID in the PMT of the MPEG-2 TS is included in user private regions of “

.

4. 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 the MPEG-2 TS;

b) detecting a program access table (PAT) and a program map table (PMT) from the received MPEG-2 TS;

c) obtaining object information included in the PMT according to a user'"'"'s request; and

d) performing an operation according to the user'"'"'s request based on the obtained object information.

5. The method as claimed in claim 4, wherein the MPEG-2 TS is a transport stream in which object information acquired from an MPEG-4 SL (Sync Layer) is aligned corresponding to a user private stream ID in the PMT of the MPEG-2 TS.

6. The method as claimed in claim 4, further comprising step e) of repeating steps b) to d) until no more user'"'"'s requests exist.

7. The method as claimed in claim 6, wherein the operation according to the user request is an operation for selecting an MPEG-2 TS including the object information.

8. The method as claimed in claim 6, wherein the operation according to the user request is an operation for removing an MPEG-2 TS including the object information.
