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.
Claims19
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 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 an MPEG stream to be broadcasted on a television;
- a shot/scene unit which sets and marks an XML TAG in the corresponding GOP positions detected by the stream unit;
- an XML unit which synchronizes the marked XML TAG 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 system for synchronizing video indexing between an audio/video signal and data for a broadcast program, comprising:
- a contents production and synchronization unit which produces 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 an MPEG stream to be broadcasted on a television;
- a shot/scene unit which sets and marks an XML TAG in the corresponding GOP positions detected by the stream unit;
- an XML unit which synchronizes the marked XML TAG 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 in a system for synchronizing video indexing between an audio/video signal and data for a broadcast program, comprising:
- a simultaneous record/playback unit which simultaneously records and playbacks a broadcast program received from a broadcasting network;
- a storage unit which stores the broadcast program to be recorded in the simultaneous record/playback unit;
- an extendable markup language (XML) parser unit which analyzes an XML file in the broadcast program stored in the storage unit;
- a media control unit which synchronizes an object file in the broadcast program stored in the storage unit and controls an operation of a video cartridge recorder, where the object file is a combination of a moving picture expert group (MPEG) file and the XML file;
- a synchronization decomposition unit which searches for synchronized positions of specified section of the broadcast program based on the outputs from the XML parser unit and the media control unit;
- and
- a metadata index unit which systematically stores information output from the synchronization decomposition 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 (P/S) unit, 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 moving picture expert group (MPEG) transport stream to a broadcasting network,
- wherein the contents P/S unit includes:
- a stream unit for detecting group of pictures (GOP) positions of an MPEG stream to be broadcasted on a television,
- a shot/scene unit which sets and marks an XML TAG in the corresponding GOP positions detected by the stream unit,
- an XML unit which synchronizes the marked XML TAG 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.
