1. A receiving system, comprising:
- a media control unit which synchronizes an object file among a video transport stream stored in a storage unit and controls an operation of a video recorder;
a synchronization decomposition unit which searches for synchronized positions of a specified section of the video transport stream based on outputs from a markup language parser unit and the media control unit, wherein at least position information of the specified section of the video transport stream is detected by locating synchronized positions of the video transport stream, wherein the synchronization decomposition unit converts time information into position information by searching the synchronized position with the specified section of the video transport stream based on the outputs from the markup language parser unit; and
a metadata index unit which systematically stores information output from the synchronization decomposition unit,wherein the media control unit includes an Electronic Program Guide (EPG) unit which controls the metadata index unit such that a user can search information stored in the metadata index unit, andwherein the media control unit detects the position information and generates video indexing at any given time point when the user inputs keyword directly by typing the keyword using a remote control to match with the corresponding position that the user wants to detect.

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.

7. A receiving system, comprising:
-
a media control unit which synchronizes an object file among a video transport stream stored in a storage unit and controls an operation of a video cartridge recorder, wherein the object file is a combination of a video file and markup language file; a markup language parser unit which analyzes the markup language file among the video transport stream stored in the storage unit, wherein the storage unit stores the video transport stream; a synchronization decomposition unit which searches for synchronized positions of a specified section of the video transport stream based on outputs from the markup language parser unit and the media control unit, wherein at least position information of the specified section of the video transport stream is detected by locating synchronized positions from the video transport stream, wherein the synchronization decomposition unit converts time information into position information by searching the synchronized position with the specified section of the video transport stream based on the outputs from the markup language parser unit; and a metadata index unit which systematically stores information output from the synchronization decomposition unit, wherein the media control unit includes an Electronic Program Guide (EPG) unit which controls the metadata index unit such that a user can search information stored in the metadata index unit, and wherein the media control unit detects the position information and generates video indexing at any given time point when the user inputs keyword directly by typing the keyword using a remote control to match with the corresponding position that the user wants to detect. - View Dependent Claims (8)
