Abstract: A video-on-demand (VOD) system and method which efficiently enables a user to resume viewing of a video program from an interrupted position is disclosed. The present invention allows the user to resume viewing of a video program even if the user requests a resumption of the interrupted video program several times or through different video servers. Particularly, the video viewing characteristic information of a user terminal is not managed by a video server of the VOD system, but is managed by the user terminal. Accordingly, when a user interrupts viewing of a video program, the video server transmits to the user terminal user profile information which includes the characteristic information related to the viewing of the video program. Thereafter, if the user requests resumption of the interrupted video program using the user profile information, the video server re-transmits the video program from the interrupted position of the video program.

Abstract: A method is provided for setting a dominant color using a spatial coherency in order to improve performance of an image search function. The method includes describing an image region based on several dominant colors, a frequency of each dominant color, and a spatial coherency (SC) of the dominant color. In the method, the spatial coherency is non-uniformly quantized based on a predetermined threshold. For example, the spatial coherency (SC) may be ranged from 0 to 1 and the threshold may be set to 0.70.

Abstract: The present invention relates to an image search method capable of expressing one color feature related to a spatial color feature of a still image based on a multilevel image grid and similarity-based searching images using the thusly expressed multilevel image grid. In the present invention, hierarchical grids of different levels are generated with respect to one feature for thereby obtaining a data structure in which each cell corresponding to the grid is expressed based on a reliability on a region representative color and the region representative color, so that it is possible to fast and accurately search images with respect to a user's content-based query based on a cell matching of the same level as two image grids and different levels or a color local matching of the grid match.

Abstract: An efficient method for retrieving an image using multiple features for an image subregion is disclosed. The present invention obtains a regional representative color for the subregions and uses the regional representative color during a retrieval of a similar image if the regional representative color is reliable. Otherwise, a feature information other than the regional representative color is used.
