ITU-T H.264高级视频编码一致性规范 |
ITU-T H.264.1建议书 | 国际标准ISO/IEC 14496-4规定了测试方法,以验证比特流和解码器是否满足ITU-T H.264建议书 | ISO/IEC 14496-10规定的规范性要求:• 一个编码器,如果其产生的比特流是兼容比特流,则可以申明其兼容于ITU-T H.264建议书 | ISO/ 14496-10。• 一个解码器,如果能够按照ITU-T H.264建议书 | ISO/IEC 14496-10规定的约束条件将所有比特流行适当地解码,则可以申明其兼容于ITU-T H.264规定的条件和级别。该建议书中规定的测试提供了编码器和解码器是否满足这些要求的(非详尽的)测试方法。该配套文本由ISO/IEC 与 ITU-T/ISO/IEC 联合视频工作组(JVT)共同编写,并作为下述标准向 ISO/IEC JTC 1/SC 29/WG 11 (MPEG) 提交:ISO/IEC 14496‑4:2002/Amendment 6 (2005 E), ISO/IEC14496‑4:2004/Amendment 9, ISO/IEC 14496‑4:2004/Amendment 30, ISO/IEC 14496‑4:2004/Amendment 31, ISO/IEC 14496‑4:2004/Amendment 38, ISO/IEC 14496‑4:2004/Amendment 41, ISO/IEC 14496‑4:2004/Amendment 42, ISO/IEC 14496‑4:2004/Amendment 43 and ISO/IEC 14496‑4:2004/Amendment 45。首版获批准的ITU-T H.264.1(03/2005)建议书包含解码器测试比特流的规范,用来测试ITU-T H.264 | ISO/IEC 14496 10建议书中规定的基本型、扩展型、主型、高型、高10型和高4:2:2型对应的解码器性能。H.264.1(09/2005)建议书勘误1与ITU T H.264.1建议书第一版相结合,与ISO/IEC文本保持技术同步,并修改了一些错误,增加了一些对先前版本中未经测试的要求特性的测试。ITU-T H.264.1(06/2008)建议书第二版对ITU-T H.264.1建议书早期版本进行了相关更正,并添加了额外的比特流,用来测试 ITU T H.264 | ISO/IEC 14496 10建议书中规定的高4:4:4预测型、高10帧内、高4:2:2帧内、高4:4:4帧内和CAVLC4:4:4帧内型对应的解码器性能。ITU-T H.264.1(04/2010)建议书第三版添加了额外的比特流,用来测试ITU T H.264 | ISO/IEC 14496 10建议书中规定的约束基型、可扩展基型、可扩展高型、可扩展高帧内、多图像高型和立体高型对应的解码器性能。一些新添的比特流也用来测试已存在型的解码器性能。ITU-T H.264.1(01/2012)建议书第四版纠正了比特流和相关规范文本中的小错误。ITU-T H.264.1(10/2014)建议书第五版添加了额外的比特流,用来测试 ITU T H.264 建议书| ISO/IEC 14496 10中规定的多图像深度高型和MFC(多分辨率帧兼容)高型对应的解码器性能。ITU-T H.264.1建议书(2015年10月)第六版增加了测试解码器的更多比特流,以确定其是否符合增强型多图像深高和MFC(与多分辨率帧兼容)深高规格(由ITU‑T H.264 | ISO/IEC 14496‑10))确定。ITU-T H.264.1建议书中规定的一致性比特流可作为该建议书的电子附件,可从ITU-T测试信号数据库http://itu.int/net/ITU-T/sigdb/spevideo/Hseries-s.htm#H.264.1下载。 |
