什麼是 HDR10？

02-22-2022


HDR10 是大多數全球顯示器品牌廣泛採用的標準，因為許多大公司都實施了 HDR10 協議。 HDR10 由藍光協會、HDMI 論壇和 UHD 協會共同定義，支持 HDR 視頻內容的壓縮傳輸。 HDR10 於 2015 年 8 月 27 日被消費電子協會 (CEA) 正式定義為支持 HDR 內容的格式。在顯示器上滿足 HDR 要求的關鍵因素之一是能夠以 HDR10 格式解碼文件。

HDR10 文件需要滿足以下條件：

1. EOTF（電光傳遞函數）使用 SMPTE ST2084

2.顏色子採樣：4:2:2/4:2:0（用於壓縮視頻源）

3. 位深：10-bit

4.原色：ITU-R BT.2020

5. 元數據：SMPTE ST2086、MaxFALL、MaxCLL

**SMPTE ST2086“Mastering Display Color Volume”靜態元數據發送來自 mastering 顯示器的色彩校準數據，例如 MaxFALL（最大幀平均亮度）和 MaxCLL（最大內容亮度）靜態值，編碼為視頻流中的 SEI 消息.
