A system and method for providing object-based video services are provided. The system for providing object-based video services comprises an interactive video authoring unit which tracks an object of interest for each frame of input moving pictures with using a predetermined object tracking algorithm, generates an object tracking scenario, and links each object to additional information; a service server which stores the moving pictures, the object tracking scenario, and additional information linked to each object, and if a service is requested through a communications network, provides the object tracking algorithm, the stored moving pictures, the object tracking scenario, and the additional information; and a client unit which receives the object tracking algorithm from the service server through the communications network and installs the algorithm, and if the moving pictures, the object tracking scenario, and the additional information are provided, generates an object label image corresponding to each frame of the moving pictures according to the object tracking scenario by using the installed object tracking algorithm, extracts additional information corresponding to an object selected by a user based on the generated object label image, and displays the additional information. Accordingly, since the service server stores only tracking scenario data taking up relatively less memory than object label images, memory use in the service server can be greatly reduced. Also, since the service server transmits only tracking scenario data whose amount is very small, transmission efficiency can increase while transmission error and data distortion can be minimized.

This application claims the priority of Korean Patent Application No. 2002-20915, filed on Apr. 17, 2002 in the Korean Intellectual Property Office, which is incorporated herein in its entirety by reference.
1. Field of the Invention
The present invention relates to a video service system, and more particularly, to a video service system and method for providing object-based interactive additional information services.
The above objects and advantages of the present invention will become more apparent by describing in detail preferred embodiments thereof with reference to the attached drawings in which:
FIG. 1 is a block diagram of the structure of the prior art object-based interactive video service system;
FIG. 2 is a schematic diagram showing a process providing additional information on a selected object which is performed in a client unit 300 shown in FIG. 1;
FIG. 3 is a schematic block diagram showing an object-based video service system according to the present invention, the system comprises an interactive video authoring unit 500, a service server 600, and a client unit 700.
Referring to FIG. 3, the video authoring unit 500 tracks an object area for each frame of input moving pictures by using a predetermined object tracking algorithm, generates an object tracking scenario in which a process tracking an object is recorded, and links additional information to be provided for each object. More specifically, the video authoring unit 500 comprises a video reproducing unit 510, a video editing unit 512, an object tracking unit 514, an object link unit 516, and a tracking scenario generating unit 518.
The video reproducing unit 510 reproduces and checks input moving pictures, and the video editing unit 512 edits moving pictures desired to be provided among the input moving pictures.
