METHOD FOR ENCODING VIDEO FOR DECODER SETTING AND DEVICE THEREFOR, AND METHOD FOR DECODING VIDEO ON BASIS OF DECODER SETTING AND DEVICE THEREFOR

摘要

Provided is a video encoding method and apparatus for transmitting configuration information required to accurately reproduce an image reconstructed by a decoder. Provided is a video decoding method and apparatus for receiving configuration information required to accurately reproduce an image reconstructed by a decoder. The video decoding method includes: receiving a data stream including network abstraction layer (NAL) units; obtaining constraint information indicating whether there is a constraint on an arrangement type of samples of a picture from the data stream; and determining an arrangement method of reconstructed samples generated by decoding an encoded picture based on the constraint information.
