Introduction

Features

AJA HDP2 HD-SDI/SDI to DVI-D Video and Audio Converter

The HDP2 is a miniature HD-SDI/SDI to DVI-D converter for digital display
devices (graphics and video), such as LED, LCD, DLP and Plasma monitors (and
projectors). Using a very high quality scaling engine, the HDP2 will
automatically size 4:3 or 16:9 inputs to many DVI-D monitors. For appropriate
monitor configurations, scaling is automatically 1 to 1—for example, displaying
1920x1080 video on a WUXGA (1920x1200) monitor. Where appropriate, the
HDP2 can automatically adapt the input frame rate for monitor compatibility.
In addition, the HDP2 provides 8 channel embedded audio over HDMI, 2
channel analog audio monitoring, and a looping output of the SDI input.

The HDP2 is designed for general monitoring, perfect for use in applications
such as: General post-production reference monitoring, Client monitoring,
Presentation, Projection, Corporate displays, Kiosk applications...and much
more!

Deep color is supported in RGB and YCbCr. USB connectivity allows for easy PC/
Mac setup and field upgrades.

About Monitor Compatibility

The HDP2 is designed to work with most DVI-D monitors. HDMI monitors are
also supported with a standard, inexpensive DVI-to-HDMI cable (user supplied).
The HDP2 uses the industry standard EDID communication protocol (within
the DVI or HDMI link) to communicate with the monitor, and then adjust the
HDP2’s internal scaling engine to scale the input video to the native resolution
of the monitor. However, due to the hundreds of variations of DVI formats
currently in use, proper operation with all monitors cannot be guaranteed.

To ensure the greatest compatibility with today's available digital display devices,
the HDP2 will, by default, provide VESA or CEA standard timing.

Frame Locking

Auto: Use this mode to ensure greatest compatibility with other monitors. The

HDP2 will use standardized output timing for most monitors. If the
attached monitor (such as an HP DreamColor) is recognized as having
enhanced capabilities, then special, frame-locked timing will be used.

Manual: Selecting an output frame rate that matches the input frame rate will

provide a vertically locked signal to the monitor, and may yield the best
results. Note that not all monitors will be able to accept these signals.

Recommended Monitors

The monitors listed below have been verified to work with one or more of the
manual frame rate selections.

HP 24" LP2480zx DreamColor
Apple 23" HD Cinema, model M9178LL/A (aluminum bezel)
Sony 23", model SDM-P234
Viewsonic VP231wb
Dell 2405FPW
Barco LC-42
Barco LC-47
Westinghouse LVM-37wl
Sony Bravia Series
Sharp Aquos Series

Optimal Performance with HP LP2480zx DreamColor

When using the HDP2 with an HP LP2480zx, the best results are obtained by
using the default HDP2 “Auto” selections (no action required—unless you’ve
changed the factory defaults using the Mini Config software supplied).

Automatic 720p or 1080p Support

Monitors that report 1280x720 or 1920x1080 in their “Preferred Timing Mode”
section of EDID readback will receive a 1280x720 or 1920x1080p signal,
respectively, from the HDP2.

Manual 720p or 1080p Support

The HDP2 can be configured manually for 720p or 1080p. This is discussed under
“USB Control and Setup” later in this manual.

Note:

that a monitor capable of displaying the “Full 1080p” image be used.

VESA and CEA Timing

By default, the HDP2 will automatically output standardized VESA rate graphics where
appropriate when a computer resolution is detected, and standardized CEA rate video
when a video device, such as an HDTV is detected. Not all VESA rates are synchronous
to SMPTE standard video input rates. However, the HDP2 can be configured manually
by selecting an output frame rate that matches the incoming frame rate. By doing so,
enhanced timing signals will be generated that will be locked to the incoming video.

Note:

Some monitors may not be able to handle some of these enhanced timing
modes. For best results, refer to the list of recommended monitors that have been
tested to lock at one or more of the user-selectable frame rates.

Motion Adaptive De-interlacing

1

Video displayed on DVI progressive display devices requires de-interlacing technology
to properly display the video from its native interlace format. HDP2 uses advanced
motion adaptive de-interlacing to predict motion in the video stream and output a
quality picture using spatial and temporal comparisons on individual pixels.

10-bit and Deep Color Support

HDP2 supports the HDMI 1.3a specification for Deep Color bit depths. In operation,
HDP2 can support Deep Color bit depths up to 30 bits/pixel (1.073 billion colors).

Video Scaling

As shown in the graphic below, the HDP2 will scale the input video to the best fit for a
given monitor and video input. In cases where the input video and the monitor are
already the same or similar, the HDP2 automatically turns off scaling. For example, a
1920 x1080 video and a 1920 x1200 monitor will not be scaled.

Note:

If the HDP2 scaling is set to 1:1 via the control panel, the input raster will be displayed
unscaled. This means that input rasters smaller than the monitor appear as a “floating”
image surrounded by black. For example, a 1280 x 720 image on a 1920 x 1200 monitor
only fills about 40% of the screen. Standard definition inputs unscaled on a 1920 x 1200
monitor only fill about 20% of the screen. This mode will only work when the input
raster is smaller than the monitor resolution.

6

Vertical Locking

If the HDP2 scaling is set to “Auto”, the HDP2 will scale the image to best fit the screen
while preserving the aspect ratio. In some cases, a letterboxed or pillarboxed image
can be expected.

Depending on the input frame rate and the capabilities of the monitor in use, the
HDP2 will provide a vertically locked signal to the monitor. Because most DVI
monitors have their own internal scaling, the internal scaler of the monitor may or
may not lock vertically to the HDP2 output. The recommended monitor list shown
earlier lists only monitors which have been tested for proper vertical lock. The HDP2
works with many LED/LCD/DLP/Plasma monitors not shown on the recommended
monitor list—however, these monitors may have one of two types of issues
associated with not being vertically locked:

Frame add/drop: The monitor occasionally adds or drops a frame of video which

appears as discontinuous motion. For example, a moving object may appear

to briefly pause or jump ahead.

Motion tearing: The monitor displays video from 2 different fields or frames on screen.

This appears as a horizontal discontinuity in the video during motion. For

example, a moving object may appear to be split horizontally with the upper

part ahead or behind the lower part.

Frame Rates

Block Diagram

When the HDP2 is manually configured for a particular output frame rate, the output
will run in lock-step with the video input. For best results, (without any added or
dropped frames), select an output frame rate that matches the incoming video frame
rate.
