Abstract
Disclosed are a method and a device for indicating a pixel, and a method and a device for processing a pixel indication, in video encoding and decoding. A process of indicating a pixel by an encoder includes the steps of: determining at least one processing sub-interval, determining at least one processing sub-interval to be indicated, and indicating the at least one processing sub-interval to be indicated. A process of processing a pixel indication by a decoder includes the steps of: acquiring processing sub-interval indication information, determining at least one indicated processing sub-interval, and determining all of the at least one processing sub-interval. Under the premise that flexible selection of at least one processing sub-interval is guaranteed by applying the above-mentioned technical solutions according to embodiments of the present invention, indication information of the at least one processing sub-interval to be indicated, which is transmitted, is reduced. As a result, video compression performance is improved.
