MC44BC375U
Weighted Video Signal to Noise
Video: 100% White video signal — 1 Vpk-pk.
No audio signal
This is measured using a Demodulator in B/G
using a CCIR Rec. 567 weighting network,
100 KHz to 5.0 MHz band with sound trap
and envelope detection, and a Video
Analyzer.
The Video Analyzer measures the ratio between the amplitude of the active area
of the video signal (700 mV) and the noise level in Vrms on a video black level
which is shown below.
VideoS/N is calculated as 20 x log(700 /N) in dB.
Unweighted Video Signal to Noise
Same as above with CCIR filter disabled.
Same as above.
Video Differential Phase
Video: 5 step Grey Scale — 1 V(pp).
No audio signal
This is measured using a Demodulator in B/G
using a CCIR Rec. 567 weighting network,
100 KHz to 5.0 MHz band with sound trap,
and envelope detection, and a Video
Analyzer.
On line CCIR 330, the video analyzer DP measure consists of calculating the
difference of the Chroma phase at the black level and the different chroma
subcarrier phase angles at each step of the greyscale. The largest positive or
negative difference indicates the distortion.
The video analyzer method takes the worst step from the first 4 steps.
Video Differential Gain
Video: 5 step Grey Scale — 1 V(pp).
No audio signal
This is measured using a Demodulator in B/G
using a CCIR Rec. 567 weighting network,
100 KHz to 5.0 MHz band with sound trap
and envelope detection, and a Video
Analyzer.
On line CCIR 330 shown below, the video analyzer DG measure consists of
calculating the difference of the Chroma amplitude at the black level and the
different amplitudes at each step of the greyscale. The largest positive or
negative difference indicates the distortion.
The video analyzer method takes the worst step from the first 4 steps.
CCIR line 330 corresponds to FCC line 17 in NTSC/M standard.
