Introduction

High dynamic range (HDR) display adaptation is a key technology for ultra-high definition video, requiring stable display across devices with different display capabilities.

Effects. GB/T 46269 aims to standardize adaptive display adaptation technology for HDR video signals on terminals with different display capabilities, and is proposed to consist of two... Partial composition.

— Part 1: Metadata and Adaptation. The purpose is to define the end-to-end system framework, metadata definitions, and terminal requirements for HDR video technology. Show the adaptation process.

— Part 2: Application Guide. This section aims to help users build products and systems that support the HDR video technologies described in Part 1.

The system enables interoperability.
