Chroma 22291/23291 Video Pattern Generators combine the
signals of analog (250MHz) and DVI (165MHz) / HDMI V1.2a
(150MHz) to provide the VESA standard video signal source
for LCD Monitor/ multi-media Monitor, it also integrates the TV
(NTSC / PAL / SECAM) / SDTV / HDTV signal to fit in the multi-
media display applications for the newly risen LCD TV, PDP TV,
projector industries.
HDMI (High Definition Multimedia Interface) is the first industry-
supported, uncompressed, all-digital audio / video interface.
HDMI provides an interface between any audio/video source,
such as a set-top box, DVD player, A/V receiver, amplifier and
an audio and/or video monitor, such as a digital television
(DTV). Chroma 22291/23291 supports standard, enhanced, or
high-definition video, plus multi-channel digital audio on a single
cable. It transmits HDTV standards and supports digital audio,
with bandwidth to spare to accommodate future enhancements and
requirements.
The video signal type of HDMI output is RGB/YCbCr and the
sampling modes are 4:4:4 / 4:2:2. The audio output of HDMI
V1.2a has 8 channels with built-in low distortion sine wave that
can be input by Optical and Coaxial cable. The audio sample rate
is 32.0 / 44.1 / 48 / 88.2 / 96 / 176.4 / 192KHz.
The function of HDCP provided with Chroma 22291/23291 is
a specification to protect digital entertainment content across
the DVI & HDMI interface. The HDCP specification provides a
robust, cost-effective and transparent method for transmitting and
receiving digital entertainment content to DVI & HDMI compliant
digital displays.
For Analog signal RGB output, its pixel frequency can up to
250MHz and meet the RS-343A standard. It also supports Y, Pb,
Pr / Y, Cb, Cr / Y, R-Y, B-Y and sync signals for tri-level output
to fulfill the test requirements for HDTV. The digital signal is in
TMDS output, the pixel frequency of TMDS is 25˜165MHz and test
screen resolution supports over UXGA.
As to the TV output spec, the image and chromaticity of
22291/23291 meet the regulations of NTSC and PAL that
contain CVBS composite signal with BNC and Y/C (Luminance/
Chrominance) image/chromaticity separation signal as well as
S-Video output connector.
Chroma 22291/23291 have the functions of Closed Caption and
V-chip for TV (NTSC). The ratings of MPAA for movie, USA TV,
Canada English, and Canada French are available for selection.
Closed Captions are captions that are hidden in the video signal.
The V-Chip is a standard for placing program rating information
on a television program, so that parents can choose to filter what
program their children can watch.
Model 23291
Teletext is the generic name for a system of information broadcast
as pages of test alongside the television signal for PAL system,
22291/23291 has 5 sets of default teletext code TEST 1 to TEST
5, and 640 packets available for users to download. Following
the rising market of multi-media display the competition and
demand for product quality are getting more and more severe
as consumers often request and search for higher pixels with
less bad dots as well as low cost video display products before
purchasing. Under this circumstance, the Chroma 22291/23291
Video Pattern Generators with high resolution test quality and
multi-output can meet the multimedia display applications at
present, and the features described above make the Video Pattern
Generator a indispensable testing tool for the RD engineers and
production manufacturers.
