3-CHANNEL VIDEO AMPLIFICATION WITH OSD BLANKING

VCR2 Contrast control characteristics (minimum)

∆VCR2 Contrast control relative characteristics (minimum)

1. Measuring conditions are as given in Supplementary Table.

The setting of V14 is changed to 1.0V.

2. Measure the amplitude output at T.P21 (25 or 29). The measured

value is called VOR3 (VOG3 or VOB3), and is treated as VCR2.

3. Contrast control relative characteristics ∆VCR2 are calculated by

the equation below:

∆VCR2=VOR3/VOG3, VOG3/VOB3, VOB3/VOR3

VB1 Brightness control characteristics (maximum)

∆VB1 Brightness control relative characteristics (maximum)

1. Measuring conditions are as given in Supplementary Table.

2. Measure the output at T.P21 (25 or 29) with a voltmeter.

The measured value is called VOR7 (VOG7 or VOB7), and is treated

as VB1.

3. To obtain brightness control relative characteristics, calculate the

difference in the output between the channels, using VOR7, VOG7

and VOB7.

VSCR1 Sub contrast control characteristics (typical)

∆VSCR1 Sub contrast control relative characteristics (typical)

1. Set V4, V8 and V12 to 4.0V. Other conditions are as given in

Supplementary Table.

2. Measure the amplitude output at T.P21 (25 or 29). The measured

value is called VOR4 (VOG4 or VOB4).

3. Sub contrast control characteristics VSCR1 and relative

characteristics ∆VSCR1 are calculated, respectively, by the

equations below:

VOR4 (VOG4, VOB4) [VP-P]

VSCR1=20LOG

[VP-P]

∆VSCR1=VOR4/VOG4, VOG4/VOB4, VOB4/VOR4

VSCR2 Sub contrast control characteristics (minimum)

1. Set V4, V8 and V12 to 1.0V. Other conditions are as given in

Supplementary Table.

2. Measure the amplitude output at T.P21 (25 or 29). The measured

value is called VOR5 (VOG5 or VOB5).

3. Relative characteristics ∆VSCR2 are calculated by the equation

below:

∆VSCR2=VOR5/VOG5, VOG5/VOB5, VOB5/VOR5

VSCR3 Contrast/sub contrast control characteristics (typical)

∆VSCR3 Contrast/sub contrast control relative

characteristics (typical)

1. Set V4, V8, V12 and V14 to 3.0V. Other conditions are as given

in Supplementary Table.

2. Measure the amplitude at T.P21 (25 or 29). The measured value

is called VOR6 (VOG6 or VOB6).

VB2 Brightness control characteristics (typical)

∆VB2 Brightness control relative characteristics (typical)

1. Measuring conditions are as given in Supplementary Table.

2. Measure the output at T.P21 (25 or 29) with a voltmeter.

The measured value is called VOR7' (VOG7' or VOB7'), and is

treated as VB2.

3. To obtain brightness control relative characteristics (∆VB2),

calculate the difference in the output between the channels,

using VOR7', VOG7', and VOB7'.

∆VB2 =VOR7'-VOG7'

=VOG7'-VOB7'

=VOB7'-VOR7'

VB3 Brightness control characteristics (minimum)

∆VB3 Brightness control relative characteristics (minimum)

1. Measuring conditions are as given in Supplementary Table.

2. Measure the output at T.P21 (25 or 29) with a voltmeter.

The measured value is called VOR7" (VOG7" or VOB7"), and is

treated as VB2.

3. To obtain brightness control relative characteristics (∆VB3),

calculate the difference in the output between the channels,

using VOR7", VOG7" and VOB7".

∆VB3 =VOR7''-VOG7''

=VOG7''-VOB7''

=VOB7''-VOR7''

1. Measuring conditions are as given in Supplementary Table.

2. SG2 and SG3 are input. The amplitude of the waveform output at

T.P21 (25 or 29) is measured by the same procedure as in GV,

∆GV.
