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 are a method for encoding a video for transmitting necessary setting information so as to exactly reproduce an image restored by a decoder, and a device therefor. Provided are a method for decoding a video for receiving necessary setting information so as to exactly reproduce an image restored by a decoder, and a device therefor. The method for decoding a video, according to various embodiments, comprises: receiving a data stream having network abstraction layer (NAL) units; obtaining, from the data stream, constraint information that indicates whether there is a constraint on an arrangement type of samples of a picture; and determining an arrangement method of samples restored from an encoded picture on the basis of the obtained constraint information.
