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： An apparatus and method for coding and decoding an image are provided. The apparatus for coding the image includes a spatio-temporal information prediction/compensation unit, a recovered image processor, a residue generator, a quantizer, and an entropy encoder. The spatio-temporal information prediction/compensation unit generates a predicted image by predicting and compensating spatio-temporal information including at least one of temporal prediction information from a current image and a recovered previous image, and spatial prediction information from a recovered current image. The recovered image processor performs a spatio-temporal noise removal process on the recovered current image using the spatio-temporal information, and stores the resulting noise-removed image. The residue generator generates a residue image obtained by subtracting the predicted image from the input image, and the quantizer outputs quantized coefficients by quantizing the residue image. The entropy encoder generates a bit stream by entropy coding the quantized coefficients.

摘要： A method and apparatus for encoding and decoding image data. The method of encoding image data includes spatially predicting pixel values of a one-dimensional block of an image using blocks spatially adjacent to the one-dimensional block or temporally predicting the pixel values of the one-dimensional block using a temporally previous frame; transforming and quantizing the pixel values of the one-dimensional block; and generating bit streams for a one-dimensional conversion block when the transformed and quantized one-dimensional block is defined as the one-dimensional conversion block. Therefore, since the method and apparatus encode and decode image data in one-dimensional block units, real-time encoding and decoding can be achieved. In addition, compression efficiency can be enhanced while minimizing visual degradation of image quality.
