    摘要： Disclosed is video encoding technology, and more particularly a method for searching for a motion vector in a procedure of estimating a motion in video frames. The motion vector search method includes the steps of: individually calculating error energies of a center point and vertices of a search pattern in a search window used in a previous frame with respect to a center of the search window established in the current frame, thereby designating a motion vector candidate point; either determining the motion vector candidate point as a moving point of a motion vector, or calculating error energies of a pair of neighboring points and re-establishing a motion vector candidate point; and either determining the re-established motion vector candidate point as a moving point of a motion vector, or re-establishing a search pattern, re-checking the error energies of the center point, the vertices and the neighboring points, and determining a moving point of a motion vector.

    摘要： A system and method for performing a handover of a mobile station (MS) by considering Quality of Service (QoS) in a broadband mobile communication system. The method can include the steps of: receiving information about one or more neighbor base stations and reception strengths for the neighbor base stations from a Serving Radio Access System (RAS) currently communicating with the MS; extracting a value of a specific field from the received information about the neighbor base stations; combining the extracted value of the specific field with the reception strengths to thereby obtain combined values, and selecting a maximum value among the combined values; and transmitting a handover (handoff) request message to a base station corresponding to the selected maximum value. The system includes an MS that analyzes information about neighbor stations received in a Mobile Neighbor Base-station Advertisement (MOB_NBR_ADV) message to select a target RAS.

    摘要： Disclosed is a method for extracting a region-of-interest of a user in a multimedia mobile terminal. The method includes: setting a search region in an input picture input to the multimedia mobile terminal on a screen picture-to-screen picture basis, and extracting a group of boundary of a region-of-interest based on a brightness difference between the set search region and an environment around the set search region; determining boundary coordinates of the region-of-interest through learning during a predetermined frame among the extracted group of boundary coordinate candidates; and enlarging the region-of-interest having the determined boundary coordinates, and displaying the enlarged region-of-interest. As a result, a region the user is most interested in or pays more attention to than other regions on a screen is automatically extracted. Accordingly, it is possible for users to view pictures in such an efficient manner as to provide the users with an even better experience and understanding during viewing.

    摘要： A motion search method and apparatus for minimizing an off-chip memory access to reduce cycles for predicting a motion vector. A sum of absolute differences (SAD) calculation processing is performed, while an off-chip memory is accessed using Direct Memory Access (DMA). A position of a current macro block is determined if a frame is input and the length of a horizontal search line is set according to adjacent motion vectors and predetermined external parameters. The SADs are calculated by calculating medians of the adjacent motion vectors as a predictive motion vector, setting a vertical direction value of the predictive motion vector as an initial search line, and sequentially searching at least one horizontal search line, and determining a position of a minimum SAD from the at least one horizontal search line. The minimum SAD position is selected as a final motion vector.
