CISPR TR 29:2020作为CISPR TR 29:2020 RLV提供，其中包含国际标准及其红线版本，显示了与上一版本相比技术内容的所有变化。CISPR TR 29:2020是一份技术报告，描述了在模拟和数字电视广播接收器及相关设备的抗扰度测试中用于客观图像评估的算法。所使用的算法是基于最初包含在CISPR 20:2002/AMD2:2004附录K中的规范开发的，该规范的最新版本已被CISPR 35:2016取代。该附件中描述的客观图像评估方法采用相同的干扰机制，并且基于与CISPR 35中针对主观图像评估规定的相同的所需信号定义。因此，客观图片评估构成了主观方法的替代方案，并提供了与主观方法直接相关的优势。这第二版取消并取代了2004年出版的第一版。本版构成技术修订版。与上一版相比，此版本包括以下重大技术变更:-参考文献的更新，以及-编辑改进。

CISPR TR 29:2020 is available as CISPR TR 29:2020 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

CISPR TR 29:2020, which is a technical report, describes the algorithms used for objective picture assessment in immunity tests of analogue and digital TV broadcast receivers and associated equipment. The algorithms used were developed on the basis of the specifications originally included in Annex K of CISPR 20:2002/AMD2:2004, the later edition of which has been replaced by CISPR 35:2016. The method of objective picture assessment described in that annex employs the same interference mechanism and is based on the same wanted signal definition as specified in CISPR 35 for subjective picture assessment. Objective picture assessment, therefore, constitutes an alternative to the subjective method and offers the advantage of direct correlation to the subjective method. This second edition cancels and replaces the first edition published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
- update of the references, and
- editorial improvements.
