Abstract

According to the disclosure of this document, scaling list data transmitted from an adaptive parameter set (APS) may be signaled through a hierarchical structure, and a limitation is applied to the scaling list data transmitted from the APS, whereby the amount of data to be signaled for video / image encoding may be reduced, and ease of implementation may be provided.

Description

technical field [0001] This technology involves video or image coding. For example, the present technique relates to encoding techniques based on zoom list data. Background technique [0002] Demands for high-resolution and high-quality images and videos such as ultra-high-definition (HUD) images and 4K or 8K or larger videos are increasing recently in various fields. As image and video data become high resolution and high quality, the relative amount of transmitted information or the number of bits increases compared with existing image and video data. Therefore, if image data is transmitted using a medium such as an existing wired or wireless broadband line or image and video data is stored using an existing storage medium, transmission costs and storage costs increase. [0003] Furthermore, there has recently been increasing interest and demand for immersive media such as virtual reality (VR), artificial reality (AR) content, or holograms. Broadcasting of images and vi...
