2.2.2.1.1 Connected video signal source to AV port:
2.2.2.1.1.1 In color bar (COL_SMPTE) pattern,
a. The color from left side to right side should be White, Yellow, Sky Blue, Green, Magenta, Red and Blue.
b. The low light 10.7 IRE in the right bottom side should be separate clear.
c. Used the Blue color filter to check the Hue and Saturation were in the optimize point.
(Saturation: The Blue and White color should be the same when see through by Blue color filter.)
(Hue: The Magenta and Sky Blue color should be the same when see through by Blue color filter.)
2.2.2.1.1.2 In Crosshatch pattern, it should be no visible noise.
2.2.2.1.1.3 In Multi burst pattern:
a. In low bandwidth pattern, there are no any dots on the edge transitions.
b. In high bandwidth pattern, can not loss any resolution and the scaling should be correct.
c. There is no visible noise in this pattern.
2.2.2.1.1.4 In Black & White, there is no any trouble at edge transition.
2.2.2.1.1.5 In Gray Scale pattern, the gray scale should not be saturation.
2.2.2.1.2. Connected video signal source to S-Video port:
2.2.2.1.2.1 In color bar (COL_SMPTE) pattern:
a. The color from left side to right side should be White, Yellow, Sky Blue, Green, Magenta, Red and Blue.
b. There were no any dot crawl between color bar, but still had light smearing.
c. The low light 10.7 IRE in the right bottom side should be separate clear.
d. Used the Blue color filter to check the Hue and Saturation were in the optimize point.
(Saturation: the Blue and White color should be the same when see through by Blue color filter.)
(Hue: the Magenta and Sky Blue color should be the same when see through by Blue color filter.)
2.2.2.1.2.2. In Crosshatch pattern, it should be no visible noise.
2.2.2.1.2.3 In Multi burst pattern:
a. In low bandwidth pattern, there are no any dots on the edge transitions.
b. In high bandwidth pattern, can not loss any resolution and the scaling should be correct.
c. There is no visible noise in this pattern.
2.2.2.1.2.4 In Black & White, there is no any trouble at edge transition.
2.2.2.1.2.5 In Gray Scale pattern, the gray scale should not be saturation.
2.2.2.1.3 Connected video signal source to Color Stream HD (YPbPr) port:
2.2.2.1.3.1 In color bar (COL_SMPTE) pattern:
a. The color from left side to right side should be White, Yellow, Sky Blue, Green, Magenta, Red and Blue.
b. There were no any dot crawl and smearing between color bar.
c. The low light in the right bottom side should be separate clear.
2.2.2.1.3.2. In Crosshatch pattern, it should be no visible noise.
2.2.2.1.3.3 In Multi burst pattern:
a. In low bandwidth pattern, there are no any dots on the edge transitions.
b. In high bandwidth pattern, can not loss any resolution and the scaling should be correct.
c. There is no visible noise in this pattern.
2.2.2.1.3.4 In Black & White, there is no any trouble at edge transition.
2.2.2.1.3.5 In Gray Scale pattern, the gray scale should not be saturation.
2.2.2.1.4 Connected video signal source to TV (Composite Video) port:
2.2.2.1.4.1 Test Channel:
a. Channel 1 ~ Channel 6 (55.25 MHz ~ 77.25 MHz), choice one channel to test.
b. Channel 95 ~ Channel 99 (91.25 MHz ~ 115.25 MHz), choice one channel to test.
c. Channel 14 ~ Channel 22 (121.25 MHz ~ 169.25 MHz), choice one channel to test.
d. Channel 7 ~ Channel 94 (175.25 MHz ~ 643.25 MHz), choice one channel to test.
e. Channel 100 ~ Channel 125 (649.25 MHz ~ 799.25 MHz), choice one channel to test.
2.2.2.1.4.2 In color bar (COL_SMPTE) pattern,
a. The color from left side to right side should be White, Yellow, Sky Blue, Green, Magenta, Red and Blue.
b. The low light 10.7 IRE in the right bottom side should be separate clear.
c. Used the Blue color filter to check the Hue and Saturation were in the optimize point.
(Saturation: the Blue and White color should be the same when see through by Blue color filter.)
(Hue: the Magenta and Sky Blue color should be the same when see through by Blue color filter.)
