1 ClearView Video Analysis System
The ClearView Video Analysis system is a full-reference video quality analysis system that provides all the
tools necessary for R&D laboratories, broadcasters, and transmission engineers to make deterministic
measurements of video quality.
Capture Features:
The ClearView systems allow the capture of video content from virtually any source -- file, SDI, HD-SDI, DVI,
VGA, HDMI, Component, Composite, and S-Video. Regardless of the input, the video is converted, based on
user choice, to fully uncompressed 4:2:2 Y’CbCr, 4:4:4 RGB, ARGB, or RGBA. Any inputted video sequence,
regardless of dimensions, can be cropped or matted to fit into the selected output raster.
Analysis Features:
Analysis begins on any two video sequences which share the same resolution and color space. The goal is to
calculate the video quality without human intervention – termed objective analysis. ClearView calculates the
pixel differences between the video sequences and displays them as A-B with thresholding and add-back.
Add-back shows where pixels are greater than the threshold. Without Add-back shows the actual value of the
pixel differences. The Pixel Value tool shows the Y’CbCr or RGB values at the pixel location for each video
sequence.
ClearView applies various objective metrics to each frame of the video sequences, generates graphs, and
logs the results. The current objective metrics supported include PSNR, SPATIAL, and TEMPORAL as
defined by ITU-T P.910. While development of more advanced algorithms are ongoing, ClearView offers
subjective viewing modes with objective measurements.
ClearView can easily be programmed to display video sequences for the expert viewers; while recording the
objective metric score. While the Mean Objective Score (MOS) cannot be repeated, the objective metric can
be easily and readily.
To aid in subjective video analysis, ClearView displays the video sequences at any rate in side-by-side,
seamless split, or split mirror.
Playout Features:
Output rates are independent from input rates; so any video sequence can be outputted at rates in excess of
120Hz. The user has control over shuttle rates, jog, color look-up tables, zoom/pan, and field display. The
video sequences are previewed within the ClearView Interface and sent to HD-SDI, SDI, Component, S-
Video, Composite, DVI, VGA, and HDMI. Normally, the video sequences are shown on the same display, but
using the Broadcast I/O DL module, each video sequence can be outputted via a separate HD-SDI/SDI link.
Video Sequence or a portion of the video sequence can also be exported as uncompressed BMP, RAW or
AVI files.

4 Unpacking ClearView
Prior to connecting the Video I/O cables (with the exception of your Windows Desktop Display), you should
first power up the system to make sure that it arrived intact.
After updating ClearView with any corporate IT required software, launch the ClearView icon on the desktop.
If you receive an error message, you have made a change to the machine ID. This is ok. You simply need to
copy the new machine name into an email, and send it to [e-mail]. Detailed
instructions for doing this are listed in the Licenses section.
After checking that everything is in working order, shut the system down, and connect all of the necessary
Video I/O. Information on the various module I/Os can be found in the Hardware Modules section.
Note: Due to DVI EDID specifications, the desired DVI monitor must be connected to ClearView’s DVI Output
at power-on time.

5 Windows Desktop Display
If you have purchased the DVI Output module, connect a DVI or VGA display to the lower connector
Note: A DVI to VGA converter is shipped with the unit
If you have not purchased the DVI Output module, connect a VGA display to the VGA connector
next to the Ethernet ports.
Note: to differentiate the DVI Output Module from the DVI Input Module, look for the S-video connector. This
is the DVI Output Module. This output is not supported but is useful for finding the proper card.

7.3 CV-DVI-Output Module
The DVI/VGA Output Module consists of a Dual-output DVI/VGA card. The primary output is the Windows
Desktop and the ClearView User Interface. The secondary output is a dedicated, video-only output controlled
by ClearView. When ClearView is not running, the output should be an extension of the Windows desktop.
Note: To send to a VGA monitor, use one of the included DVI/VGA adapters.
7.4 CV-DVI-I-720 Module
The model -720 has a single DVI Input connector and a single DVI pass-through connector. If your source
device looks for a monitor’s EDID, you must have a DVI monitor attached to the pass-through connector
which is capable of displaying the video format you would like to capture.
Note: unless you have the CV-DVI-Output module installed. In this case, you can attach the monitor to output
#2).

7.5 CV-DVI-I-1080 Module
The –1080 DVI Input Module actually consists of three physical DVI capture cards. Each card captures one
of the three DVI components (Red, Green, and Blue). The three streams are then combined into a single 32
bit ARGB video sequence, in a separate export process after the capture.
ClearView DVI-I-1080 Input Module including cables and DVI Distribution Amp.
The DVI Distribution Amplifier (from Gefen) takes the incoming DVI signal and sends it to all three DVI
capture cards. It also sends the signal to a DVI monitor for viewing the capture process.

DVI Input to ClearView
DV Power In
DVI Output to Monitor
To ClearView DVI Input 1
To ClearView DVI Input 2
To ClearView DVI Input 3
Nearly all DVI video sources detect the display device and restrict the sources outputs based on what the
display will accept. This standard is known as EDID (Electronic Device Interface Definition). In order to
capture DVI video from most sources, you will need to have a monitor connected to Output number one on
the DVI Distribution Amp which supports the desired video format. The DVI Distribution Amp looks to Output
Number one (bottom right) for the EDID information which is then passed back to the DVI source.
7.5.1 Connections:
Connect all DVI cable prior to powering on the DVI Distribution Amp.
DVI Output number one (1), located at the bottom right, must be connected to a DVI monitor capable of
supporting the video format to be captured.
The other three outputs connect to each of the three DVI Input Module’s connectors. It does not matter which
goes to which.
•Power on the Monitor
•Power on the DVI Distribution Amp
•Power on ClearView
•Power on the DVI source
The source should now read the EDID info from the monitor, through the DVI Distribution Amp.
7.6 DVB/ASI Input/Output Module
This module resides in a single card and allows for simultaneous input and output of DVB/ASI (Asynchronous
Parallel Interface). Use Low-Loss Serial Digital video cables for all connections to other DVB/ASI compliant
devices.
