Abstract
In the present system and method, synchronization information is inserted into specified positions of the content of a multimedia stream at the time when the contents are produced. Thus, the present invention enables a user to easily search the synchronization information on the specified positions through an annotation. As a result, a user can selectively control the playback of a video cartridge recorder through the annotation of a recorded MPEG stream.
Claims16
A system for synchronizing video indexing between an audio/video (A/V) signal and data for a broadcast program, comprising:
- a broadcast data synchronization and transmission system which produces a live broadcast program to be broadcasted and Extendible Markup Language (XML) TAG information for the live broadcast program, combines the XML TAG information with the produced broadcast program, and transmits the combined data of a Moving Picture Expert Group (MPEG) transport stream to a broadcasting network,
- wherein the broadcast data synchronization and transmission system includes a contents production and synchronization unit which comprises:
- a stream unit which detects group of pictures (GOP) positions of the MPEG stream to be broadcasted on a television;
- and
- a shot/scene unit which sets and marks the XML TAG information in the corresponding GOP positions detected by the stream unit.
A system for synchronizing video indexing between an audio/video (A/V) signal and data for a broadcast program, comprising:
- a broadcast data synchronization and transmission system which produces a live broadcast program to be broadcasted and Extendible Markup Language (XML) TAG information for the live broadcast program, combines the XML TAG information with the produced broadcast program, and transmits the combined data of a Moving Picture Expert Group (MPEG) transport stream to a broadcasting network,
- wherein the broadcast data synchronization and transmission system includes a contents production and synchronization unit which comprises:
- an XML unit which synchronizes marked XML TAG information with the MPEG stream to be broadcasted;
- and
- a generation unit which generates and outputs the XML TAG information based upon the result from the XML unit.
A receiving system for synchronizing video indexing between an audio/video (A/V) signal and data for a broadcast program, comprising:
- a media control unit which synchronizes an object file among a Motion Picture Expert Group (MPEG) transport stream stored in a storage unit and controls an operation of a video cartridge recorder, where the object file is a combination of an MPEG file and an Extendible Markup Language (XML) file;
- a synchronization decomposition unit which searches for synchronized positions of a specified section of the MPEG stream based on outputs from an XML parser unit and the media control unit;
- and
- a metadata index unit which systematically stores information output from the synchronization decomposition unit.
A system for synchronizing video indexing between an audio/video (A/V) signal and data for a broadcast program, comprising:
- a broadcast data synchronization and transmission system which includes a stream unit for detecting group of pictures (GOP) positions of a Motion Picture Expert Group (MPEG) stream to be broadcasted on a television, and a shot/scene unit for setting and marking Extendible Markup Language (XML) TAG information in the corresponding GOP positions detected by the stream unit;
- and
- a receiving system which includes a media control unit for synchronizing an object file among the MPEG transport stream stored in a storage unit and controlling an operation of a video cartridge recorder, where the object file is a combination of an MPEG file and an XML file, a synchronization decomposition unit for searching for synchronized positions of a specified section of the MPEG stream based on outputs from an XML parser unit and the media control unit, and a metadata index unit for systematically storing information output from the synchronization decomposition unit.
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.
A receiving system, comprising:
- a media control unit which synchronizes an object file among a Motion Picture Expert Group (MPEG) transport stream stored in a storage unit and controls an operation of a video cartridge recorder, where the object file is a combination of an MPEG file and an Extendible Markup Language (XML) file;
- an XML parser unit which analyzes the XML file among the MPEG transport stream stored in the storage unit;
- a synchronization decomposition unit which searches for synchronized positions of specified section of the MPEG stream based on outputs from an XML parser unit and the media control unit;
- and
- a metadata index unit which systematically stores information output from the synchronization decomposition unit.
A system for synchronizing video indexing between an audio/video (A/V) signal and data for a broadcast program, comprising:
- a contents production and synchronization unit which produces a live broadcast program to be broadcasted and Extendible Markup Language (XML) TAG information of the broadcast program;
- and
- a data transmission unit which combines the XML TAG information from the contents production and synchronization unit with the produced broadcast program, and transmits the combined data as a Moving Picture Expert Group (MPEG) transport stream to a broadcasting network,
- wherein the contents production and synchronization unit comprises:
- a stream unit which detects group of pictures (GOP) positions of the MPEG stream to be broadcasted on a television;
- and
- a shot/scene unit which sets and marks the XML TAG information in the corresponding GOP positions detected by the stream unit.
A method for synchronizing video indexing between an audio/video (A/V) signal and data for a broadcast program, comprising:
- producing, at a contents production and synchronization unit, a live broadcast program to be broadcasted and Extendible Markup Language (XML) TAG information for the live broadcast program;
- and
- combining, at a data transmission unit, the XML TAG information with the produced broadcast program, and transmitting the combined data in a form of a Motion Picture Expert Group (MPEG) transport stream to a broadcasting network,
- wherein the contents production and synchronization unit includes a stream unit which detects group of pictures (GOP) positions of the MPEG stream to be broadcasted on a television, and a shot/scene unit which sets and marks the XML TAG information in the corresponding GOP positions detected by the stream unit.
