Introduction

This specification is based on JJF 1071-2010 "Rules for the Compilation of National Metrology and Calibration Specifications" and JJF 1059.1-2012 "Evaluation and Expression of Measurement Uncertainty" was compiled. This specification mainly stipulates the calibration method of HD video signal generator with analog component output. This specification refers to GB 3659-1983 "TV Video Channel Test Method", SJ/T 11332 "Digital TV Receiver Equipment Interface Specification Part 6.RGB Analog Primary Color Video Signal Interface", SJ/T 11333 "Digital TV Reception Equipment Interface Specification Part 7.YPBPR Analog Component Video Signal Interface" and other currently valid versions. In Appendix C, calibration items such as high-definition video level, inter-channel delay, signal-to-noise ratio, driving signal amplitude, etc. are given Example of evaluation of measurement uncertainty. The definition of high-definition video signal is given in Appendix D, including. signal system The definition of formula, signal conversion and image signal waveform. This specification is released for the first time. HD video signal generator calibration specification

1 Scope

This specification applies to the calibration of high-definition video signal generators with analog component output.

2 Reference documents

This specification refers to the following documents. GB 3659-1983 TV video channel test method SJ/T 11332 Digital TV receiving equipment interface specification Part 6.RGB analog primary color video signal interface SJ/T 11333 Digital TV receiving equipment interface specification Part 7.YPBPR analog component video signal interface For dated reference documents, only the dated version applies to this specification; for undated references The latest version (including all amendments) is applicable to this specification.

3 Terms and units of measurement

3.1 RGB analog element video signal RGB analogelementvideosignal Red (R), green (G), blue with the same bandwidth, with or with additional synchronization information, synchronized with each other, gamma-corrected (B) Three primary color analog video signals. 3.2 YPBPR analog component video signal YPBPRanalogcomponentvideosignal Y, PB, and PR signals are brightness signal (Y), blue difference signal (BY) and red difference signal (RY) respectively The analog signal obtained by multiplying the amplitude value of a scale factor. At least the Y signal contains a sync pulse signal. 3.3 Bipolar three-level synchronizing pulse signal A synchronization signal composed of negative and positive pulses and 0 level. The tick corresponds to the scan synchronization timing reference. 3.4 video signal-to-noise ratio videosignaltonoiseratio The ratio of the video signal level value to the effective value of the noise amplitude is calculated according to formula (1). S/N=20×lg Nrms (1) Where. S/N---Video signal-to-noise ratio, dB; V---Video signal level value, take 700mV; Nrms---the effective value of the noise amplitude, mV.

4 overview
