摘要： Disclosed is a method of decoding an image and a method of encoding an image. The method of decoding an image includes: obtaining motion-constrained tile set information; determining, on the basis of the motion-constrained tile set information, a first boundary region of a collocated tile set within a reference picture, which corresponds to a motion-constrained tile set; padding a second boundary region corresponding to the first boundary region; and performing inter prediction on the motion-constrained tile set by using a collocated tile set that includes the padded second boundary region.

摘要： Provided is a bit rate control methods includes determining an input bit count for a rate quantization model according to a target bit rate setting; and providing a quantization parameter value determined through the rate quantization model to an encoder unit based on the input bit count. The rate quantization model is updated according to a prediction bit count information predicted from a BIN count information of a current or delay frame encoded in an encoder unit and the delay bit count information of the delay frame obtained from an offline context-adaptive binary arithmetic coding CABAC module.

摘要： Provided is a video processing apparatus for processing motion compensation of a plurality of frames. The video processing apparatus includes an image receiving receiver, a filter, a block divider, a compression processor, and a frame buffer memory. The image receiving receiver receives encoded data The filter an image frame reconstructed from the encoded data, and a block divider divides a reference frame into a plurality of blocks in a predetermined block dividing unit. The each of the plurality of blocks has an identical size. A compression processor compresses each of the plurality of blocks in a method selected from one of an uncompression method or a lossless compression method on a basis of reduction or non-reduction of bandwidths with respect to a frame buffer memory that contains the reference frame and packages the plurality of blocks in a unit of a burst group. A size of the burst group corresponds to a burst length of the frame buffer memory. The frame buffer memory records the packaged data and provides the reference frame for the emotion compensation. The lossless compression method includes a lossless variable-length compression method, such as a DPCM entropy coding method.
