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 method, medium, and system encoding and/or decoding image data by dividing image data into block units, and generating a bitstream by entropy encoding the image data in order of the divided blocks. The decoding method may include receiving an input of a bitstream, and restoring image data by entropy decoding the block units of the bitstream. According to the method, medium, and system, when image data is encoded and/or decoded by using a residue color transform, a bitstream can be generated and encoded in block units of the image, and when the bitstream is decoded, an image can be restored from the bitstream. By doing so, the conventional delay of image processing can be prevented.

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/or decoding image data. The encoding method includes: if the color space of an image is a single color space, correcting pixel values by applying identical correction pixel values to all color components of a previous image, and if the color space of the image is not a single color space, correcting pixel values by applying different correction pixel values to the color components of the previous image; performing temporal prediction encoding of a current image by using the corrected pixel values of the previous image; quantizing the prediction encoded data; and generating a bitstream by entropy encoding the quantized data. According to the method and apparatus, when the pixel values of a previous image are desired to be corrected in order to perform temporal prediction encoding, different pixel value correction methods are applied according to whether or not the characteristics of color components included in the color space of the image desired to be encoded. By doing so, when image data is encoded, the encoding can be performed adaptively to a variety of color spaces and higher compression efficiency can be maintained.
