SMPTE Color Bars

In addition to pluge, SMPTE Color Bars includes a reverse sequence of bars.

The reverse sequence helps adjust monitor levels on monitors that provide blue

only displays. Hue can be aligned by balancing the chroma bars, and chroma can

be set by matching the chroma bars to the white bars.

Black Test Patterns

These test patterns are field field luminance reference levels. Black can be used as a color

black reference signal and the others can be used as flat luminance mattes.

Black

The composite black test pattern has characteristics that are described in the

following table:

Characteristic Requirement

Black Level 7.5 +/- 1 IRE (NTSC)

0 +/- 1 IRE (PAL and Japan*)

Blanking Width 10.9 +/- 0.2 uSec

Sync Level -40 +/- 2 IRE (NTSC)

-300 +/- 15 mV (PAL)

Sync Width 4.7 +/- 0.1 uSec

Burst Level 40 +/- 1 IRE (NTSC)

300 +/- 15 mV (PAL)

Burst Frequency 3.579545 MHz (NTSC)

4.43361875 MHz (PAL)

SCH Phase 0 +/- 3 degrees

Color Field Sequence 4 Fields (NTSC)

8 Fields (PAL)

* Setup is removed with an on board jumper

The serial black pattern has a narrower blanking width of 10.2 uSec.

50%, 80%, and Peak White

These full field luminance mattes have 10 bit luminance levels of 1F6h, 2FDh, and

3ACh.
