Embodiment Construction
[0029] Hereinafter, a system and method for time synchronization between multimedia content and segment metadata according to an embodiment of the present invention will be described with reference to the accompanying drawings.
[0030] FIG. 2 is a view showing flows of content and metadata in a digital television broadcasting environment according to an embodiment of the present invention. Referring to FIG. 2, a content generator 210 generates content and provides the generated content to a broadcasting device 220, such as a broadcasting station, which in turn broadcasts the received content. The metadata generator 230 receives broadcast content, generates metadata for the received content, and then forwards the generated metadata to the metadata provider 240, which next sends the received metadata to the receiver. Machine 250. Also, the receiver 250 receives broadcast content from the broadcaster 220 through a channel different from the metadata transmission channel, and pe...

A system and method for time synchronization between multimedia content and segment metadata. Disclosed is a time synchronization system (300) including a content processor (325) for receiving and storing multimedia content containing first segment time information; a metadata processor (310) for receiving and storing segment metadata for the content containing second segment time information; a synchronizer (320) for extracting the first segment time information from the multimedia content and the second segment time information from the metadata in response to a request of a user, determining respective reference time points from the first and second extracted segment time information, correcting a relative time point of the content using a difference between the determined reference time points, and synchronizing the received content and metadata using the corrected relative time point; and a content segment browser (305) for forwarding the content segment request signal to the synchronizer and reproducing a plurality of segments of the content synchronized by the synchronizer.
Description
[0001] This application claims priority from Korean Patent Application No. 10-2003-0043520 filed in the Korean Intellectual Property Office on Jun. 30, 2003, which is hereby incorporated by reference. technical field [0002] The apparatus and method according to the present invention relate to time synchronization between multimedia content and segment metadata for multimedia content, and more particularly, to a method of synchronizing content and segment metadata received via different transmission channels using predetermined time information Systems and methods for synchronization. Background technique [0003] As the distribution of digital broadcasting services becomes more and more widespread, technical development for efficient application using multimedia contents (in the present invention, various types of contents mentioned below are regarded as multimedia contents) is extremely required. For example, there is provided a personal video recorder (PVR) application t...
