摘要： Disclosed is an intelligent display method for a multimedia mobile terminal. The method includes the steps of determining a type of a camera shot existing in a sport game video; deciding a region of interest within an image frame of the sport game video when it has been determined that the camera shot is a long-distance shot, magnifying the region of interest, and displaying the region of interest on the mobile terminal, and displaying the entire image frame on the mobile terminal when it has been determined that the video shot is a non-long-distance shot. The method enables the user to watch images in a more understandable and comfortable manner.

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： A method, apparatus and system for providing a video service of a video service system including multimedia video in real time to a mobile terminal connected by a wireless network. A video frame coded by a coding scheme is transmitted to the mobile terminal for decoding and display. The coding scheme may include a first coding scheme and a second coding scheme used together at a predetermined ratio according to the mobile terminal demanding the video service. A server typically receives coding scheme change determining information from the mobile terminal in order to determining whether or not to change the coding scheme for the video frame during transmission of the video frame. The changed coding scheme can be used to transmit the video frame to the mobile terminal according to the result of analyzing the coding scheme change determining information.

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： Methods and apparatus for video frame rate conversion are disclosed. In one aspect of the invention, a basic interpolation motion vector for an interpolated frame is generated using a motion vector of a current frame. The motion vector of the current frame is compared with a motion vector of a previous frame. The basic interpolation motion vector is offset and corrected according to a comparison result. The interpolated frame is generated by performing motion compensation using at least one of the basic interpolation motion vector and the corrected basic interpolation motion vector.
