Abstract

The present invention provides a method for processing a bitstream in which an image sequence divided into a plurality of sub-images is encoded. The method comprises the steps of: decoding, from a bitstream, division information indicating a division structure in which an image belonging to a sequence is divided into sub-images; decoding ID information related to the sub-images, and mapping an ID to each of the sub-images by using the ID information; and reconstructing the block within the at least one sub-image by using the mapped ID.

Description

technical field [0001] The present invention relates to encoding and decoding of video, and more particularly, the present invention relates to partitioning each picture into independently displayable sub-pictures and encoding and decoding each sub-picture. Background technique [0002] Since the amount of video data is larger than that of voice data or still image data, storing or transmitting video data without compression processing requires a large amount of hardware resources (including memory). [0003] Accordingly, when storing or transmitting video data, an encoder is usually used to compress the video data for storage or transmission. Then, the decoder receives the compressed video data, decompresses and reproduces the video data. Compression techniques used for such videos include H.264 / AVC and High Efficiency Video Coding (HEVC), which is approximately 40% more efficient than H.264 / AVC. %. [0004] However, the size, resolution, and frame rate of video images h...
