摘要： A method and apparatus for error concealment in decoding of a moving picture. The method includes the steps of determining an erroneous macro block in a present frame when the moving picture is decoded, finding a first macro block having a highest similarity to the erroneous macro block and a second macro block having a next highest similarity to the erroneous block in a previous frame by comparing adjacent pixels of respective blocks in the previous frame with adjacent pixels of the erroneous block in the present frame; and replacing the erroneous block by using an average between the found macro blocks having the highest similarity and the second highest similarity to thereby conceal the erroneous macro block. The apparatus includes a parser, an entropy decoder, an inverse quantizer, an inverse converter, and a concealment unit that uses motion compensation from a previous frame to correct a macro block in a current frame.

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.
