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.

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.
