摘要： Provided is a method of compressing a reference frame in encoding or decoding moving images. A reference frame to be compressed is divided into basic processing blocks. The basic processing blocks are divided into sub-blocks. A maximum value and a minimum value of pixels within each sub-block are calculated. A necessary bit length needed for compression of each sub-block is obtained based on a difference between the maximum value and the minimum value. An average bit length of the sub-blocks within the basic processing block is calculated based on the calculated necessary bit lengths of the sub-blocks. Bits are variably allocated to each sub-block by adjusting the necessary bit length of each sub-block so that the average bit length of the sub-blocks within a corresponding basic processing block is less than or equal to a preset required bit length. Each sub-block is compressed to the allocated bits.

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 for setting an output bit rate for video data transmission in a WiBro system in which an uplink state value for a predetermined unit time is calculated to determine an uplink network state of the predetermined unit time. An average of uplink state values for a predetermined number of unit times is calculated, and a video encoding bit rate is increased if the average of the uplink state values is larger than a predetermined first threshold. However, the video encoding bit rate is decreased if the average of the uplink state values is less than a predetermined second threshold.
