给出了在接收信号不符合CCIR采用的广播信号规范的情况下，电视广播接收机的测量方法。此类非标准信号可能由录像机、视频光盘播放器和电视游戏等来源产生。规定了使用现有技术的广播电视接收机特性的测量方法，这些特性通过现有类型的辅助设备和系统产生的信号性质的经验发现，在确定其相互兼容性方面具有重要意义。

Gives methods of measurement for television broadcast receivers under conditions in which the signal presented to the receiver is not in accordance with the specifications for broadcast signals adopted by the CCIR. Such nonstandard signals may be produced by video tape recorders, video disc players and television games, among other sources. Specifies methods of measurement for those characteristics of broadcast television receivers using existing technology which have been found, by experience of the nature of signals produced by existing types of ancillary equipment and systems, to be significant in determining their mutual compatibility.
