Methods of measurement on receivers for television broadcast transmissions Part 1: General considerations Electrical measurements at radio and video frequencies and measurements on d
1 Introduction
1.1 Scope
This standard deals with the standard conditions and methods of measurement on receivers for television broadcast transmissions (hereinafter referred to as receivers) that meet the requirements of terrestrial broadcast television standards specified by ITU-R (CCIR). Such receivers may be used for direct off-air reception, reception via cabled networks or as a monitor for prerecorded video, home movies and games among other applications. This standard does not include the measurements specific to the sound channel. The relevant measurement methods for sound channel are dealt with by IEC 107-2, IEC 107-3, IEC 107-4 and IEC 107-5; and the relevant measurement methods for nonstandard broadcast signals are dealt with by IEC 107-6.
This standard deals with the determination of performance permits the comparison of equipment by listing the characteristics which are useful for there performance and by laying down uniform methods of measurement for these characteristics. But performance requirements are not specified.
General safety requirements are not dealt with by this standard, and this part shall comply with IEC 65 announcement or other IEC safety standards. The requirements of disturbance and immunity to disturbance are also not dealt with by this standard; these requirements shall comply with CISPR 13 and 20 announcement.
