Description
Multiburst pattern consisting of five or six sine wave packets, each
of fixed frequency. This pattern is typically used for frequency
response testing for one or three video channels. The packets
have a 60% amplitude range upon a 50% level, therefore range
between 20% and 80% levels.
For comparison to these peak limits, flat pedestals at 80% and
20% levels are present on the left side of the pattern. The set
of packet frequencies used in each pattern is determined by the
maximum bandwidth of the output format.
For 4:2:2 YCbCr formats, one multiburst pattern consists only of
a Y channel signal, up to the maximum frequency limit, and the
second multiburst pattern is identical for all three channels, up to
half of the Y channel frequency limit.
For 4:4:4 formats, each multiburst pattern is identical for all three
channels.
(SD formats only) Three channel pattern with packet frequencies
of 0.5, 1.0, 1.5, 2.0, and 2.75 MHz.
(SD formats only) Y channel pattern with packet frequencies of
0.5, 1.0, 2.0, 3.0, 4.0 and 5.75 MHz.
(HD and 3G formats only) Three channel pattern with packet
frequencies of 1, 3, 6, 9, 12, and 15 MHz.
(HD formats only) Y channel pattern with packet frequencies of
15, 18, 21, 24, 27, and 30 MHz.
(4:4:4 and fast-progressive 3G formats only) Three channel
pattern with packet frequencies of 15, 18, 21, 24, 27, and 30 MHz.
(Fast-progressive 3G formats only) Y channel pattern with packet
frequencies of 35, 40, 45, 50, 55, and 60 MHz.
Zone plate test signal with real-time parametric controls. Select
a zone plate signal and press the ENTER button to adjust the
parametric controls.(See page 111, SDI Zone plate signals.)
Color reference chart, used with permission of DSC Laboratories.
The pattern consists of a series of DSC standard color patches
representing the six primary colors, 18 evenly spaced intermediate
colors, and four skin tone reference patches. The 24 primary
and intermediate colors will show as a hexagonal shape on a
vectorscope display, providing a reference for comparison with a
camera-generated image of a physical DSC ChromaDuMonde
chart. The pattern also includes an 11-step crossed grayscale
section and a center section with 0% black and 100% white
patches.
