Abstract

In accordance with the disclosure of this document, scaled list data sent from an adaptive parameter set (APS) may be signaled over a hierarchical structure. In addition, by applying a limit to the scaling list data transmitted from the APS, the amount of data required to be signaled for video / image encoding can be reduced, and implementation is facilitated.

Description

technical field [0001] The present technology relates to video or image coding, and for example to coding techniques based on scaling list parameters. 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 videos whose i...
