多功能视频编码 |
ITU-T H.266建议书指定了一种称为通用视频编码的视频编码技术,其设计有两个主要目标。第一个目标是指定一种缩压能力大大超过前几代此类标准的视频编码技术,第二个目标是使这种技术在比现有标准更宽的应用范围内具有更高的通用性。使用该标准的一些关键应用领域主要包括超高清视频(如ITU-R BT.2100建议书中规定的3840×2160或7620×4320图像分辨率和10位的位深度),高动态范围和宽色域的视频(例如,具有ITU-R BT.2100建议书中指定的感知量化或混合对数伽马传输特性),以及用于沉浸式媒体应用的视频,例如使用公共投影格式(例如等矩形或立方体映射投影格式)投影的360°全向视频,此外还有通常由现有视频编码标准处理的应用。 本建议书与ISO/IEC JTC 1/SC 29合作开发,与ISO/IEC 23090-3的技术文本相一致。 |
