摘要： A method, medium, and system encoding/decoding video data using a binary arithmetic coding adaptive to a compression bit rate of the video data. The system may include a bitrate adaptation unit determining a maximum length of a prefix using a compression bitrate of the video data, a binarization unit dividing the video data into a prefix and a suffix according to the determined maximum length of the prefix and binarizing the video data, and an arithmetic encoding unit performing an arithmetic encoding on the binarized video data. The video data may be encoded/decoded using binary arithmetic encoding/decoding by determining the maximum length of the prefix, an order of an exponential Golomb code, and the number of contexts based on the compression bitrate. Accordingly, it is possible to obtain high encoding efficiency regardless of a range of the desired compression bitrate.

摘要： A memory mapping apparatus and a method in a video decoder/encoder utilize a dividing unit, a storage unit and a memory allocation unit. The dividing unit divides picture data into macroblocks and divides each of the macroblocks, which are units of encoding, into partitions having a predetermined size. A storage unit comprises at least one memory bank which is independently accessible. A memory allocation unit allocates adjacent partitions to different memory banks. Accordingly, a total number of cycles necessary to read and write the picture data is reduced.

摘要： A pipelining decoding apparatus and method, and a computer-readable recording medium for storing a computer program for controlling the pipelining decoding apparatus. Pixel values of each of the recovered images corresponding to previous macroblocks are stored as neighboring pixel values. Motion is predicted in a picture corresponding to a current macro block using the stored neighboring pixel values. An original image is recovered from the current macroblock using the result of the prediction of the motion in the picture and residue information. Some of the pixel values of the recovered image corresponding to the current macroblock are stored and the recovered image is deblocking-filtered.
