Abstract

This invention is directed to a transmission system having a broadcast data synchronization and transmission system including a stream unit which detects group of pictures (GOP) positions of a Motion Picture Expert Group (MPEG) stream to be broadcasted on a television, and a shot/scene unit which sets and marks Extendible Markup Language (XML) TAG information in the corresponding GOP positions detected by the stream unit.

Claims

1. A transmission system, comprising:

a broadcast data synchronization and transmission system including a stream unit which detects group of pictures (GOP) positions of a Motion Picture Expert Group (MPEG) stream to be broadcasted on a television, and a shot/scene unit which sets and marks Extendible Markup Language (XML) TAG information in the corresponding GOP positions detected by the stream unit.

2. The system of claim 1, further comprising:

an XML unit which synchronizes the marked XML TAG information with the MPEG stream to be broadcasted; and

a generation unit which generates and outputs XML TAG information based upon a result from the XML unit.

3. The system of claim 1, wherein the broadcast data synchronization and transmission system produces a live broadcast program to be broadcasted and the XML TAG information for the live broadcast program, combines the XML TAG information with the produced broadcast program, and transmits the combined data of the MPEG transport stream to a broadcasting network.
