Embodiment Construction

[0020] Certain terms are used in the claims and description to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The claims and description do not use the difference in names as the way to distinguish components, but use the difference in function of the components as the criterion for distinguishing. The "comprising" mentioned in the claims and the specification is an open term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly electrically connected to the second device, or indirectly electrically connected to the second device through other devices or connection means. .

Abstract

The invention discloses a video encoding method and apparatus and an associated video decoding method and apparatus. A method of encoding a frame to generate an output bitstream has following steps: dividing the frame into partitions; dividing each of the partitions into blocks, wherein each of the blocks is composed of pixels; assigning a first segmentation identifier to each of first blocks located at partition boundaries each between two adjacent partitions within the frame, wherein the first blocks belong to a first segment, and the first segmentation identifier is signaled per first block; and encoding each of the blocks. The step of encoding each of the blocks includes: generating reconstructed blocks for the blocks, respectively; and configuring an in-loop filter by a predeterminedin-loop filtering setting in response to the first segmentation identifier, wherein the in-loop filter with the predetermined in-loop filtering setting does not apply in-loop filtering to each reconstructed block corresponding to the first segment.

Description

technical field [0001] The present invention relates to video coding and video decoding, and more particularly, to a video coding method and device using independent partition coding and a related video decoding method and device. Background technique [0002] Traditional video coding standards usually employ block-based coding techniques to exploit spatial and temporal redundancy. For example, the basic approach is to divide the entire source frame into blocks, perform intra prediction / inter prediction on each block, transform the residual of each block, and perform quantization and entropy coding. In addition, a reconstructed frame is generated to provide reference pixel data for encoding a following block. For some video coding standards, an in-loop filter can be used to enhance the image quality of the reconstructed frame. The video decoder is used to perform the inverse of the video encoding operation performed by the video encoder. For example, reconstructed frames...
