    摘要： A method and apparatus for encoding and decoding an image. The encoding method includes: deciding whether pixel values of a first block of an image are identical to pixel values of a second block of the image that is encoded prior to the first block in a current slice of the image, and determining whether to encode the first block in a first mode according to the deciding; and selectively encoding the first block in the first mode based on the determining, wherein the first mode is a mode for encoding information representing that the first block is encoded in the first mode, instead of encoding the pixel values of the first block, when the first block is identical or similar to the second block.

    摘要： A method and apparatus for decoding an image are provided. The method includes: decoding information representing that a first block of the image has been encoded in a first mode; and reconstructing the first block by setting pixel values of the first block to be identical with pixel values of a second block of the image that is adjacent to the first block and has been decoded prior to the first block, wherein the first mode is a mode for encoding information representing that the first block is identical or similar to the second block and has been encoded in the first mode, instead of encoding the pixel values of the first block.

    摘要： Methods and apparatuses for generating video packets are provided. A method of generating a video packet includes generating at least one pixel block including at least one reference pixel and at least one neighboring pixel adjacent to the at least one reference pixel from pixels of a video frame; replacing a pixel value of the at least one neighboring pixel in the at least one pixel block with a pixel difference value, which is a difference value between a pixel value of a pixel adjacent to the at least one neighboring pixel and the pixel value of the at least one neighboring pixel; and generating packets so that a pixel value of the at least one reference pixel and the pixel difference value of the at least one neighboring pixel are allocated to different packets according to positions of the pixels.

    摘要： Provided are entropy encoding and decoding methods. The entropy encoding method includes receiving residual coefficients obtained by frequency converting a residual image, determining a first bit string about residual coefficients having nonzero levels from among the received residual coefficients, determining at least one lower bit, including a least significant bit of the first bit string, from the first bit string, and determining a second bit string obtained by bit-shifting the first bit string to the right by the number of lower bits.
