By Engineers, For Engineers

In 1989, a former television station engineer who loved designing

and building video equipment, decided to start a new company.

He relished the idea of taking an existing group of equipment

and adding a few special pieces in order to create an even more

elegant ensemble. So, he designed and built his rst product and

the company was born.

Focused On What You Need

As the company has grown, more former TV station engineers have

joined Ensemble Designs and this wealth of practical

experience fuels the company’s innovation. Everyone at the

company is focused on providing the very equipment you need

Product Overview

BrightEye 5 is a Time Base Corrector with analog composite inputs and outputs. 12 bit digital signal

processing ensures the best signal handling and a solid output. BrightEye 5 will time base correct

signals from analog sources such as consumer VCRs, cameras and noisy microwave receivers.

The analog input is converted at 12 bits of resolution for digital processing. The signal is time base

corrected and frame synchronized to the reference input and converted back to analog for output.

BrightEye 5 auto detects the video standard of the input (NTSC or PAL), or can be set manually to

either NTSC or PAL if preferred.

Basic controls are provided on the front panel. With BrightEye Mac or PC software, you can control

video proc functions: Gain, Chroma, Pedestal, and Hue. The vertical interval can be passed or blanked.

A glossary of commonly used video terms is provided at the end of this user guide.

Functional Description and Block Diagram

As shown in the functional block diagram below, analog video is fed to the unit on a single BNC

connector. This analog input is converted at 12 bits of resolution for digital processing. The signal is

time base corrected and frame synchronized to the external reference input and converted back to

analog for output. The video standard of the input signal is automatically detected. For applications

with intermittent or low quality input signals, the video standard can be set manually to either NTSC or

PAL. This will improve performance when the input signal is compromised.

BrightEye 5 is powered by a 12 volt DC universal power supply. This power supply can accept an input

voltage between 90 and 230 volts, at 50 or 60 Hertz.

BrightEye 5 uses a standard IEC line cord and can be used anywhere in the world. It is normal for the

converter to be quite warm to the touch when operating.

Applications

Time Base Correction of Noisy Microwave Signal

One useful application for the BrightEye 5 is time base correction of an excessively noisy analog video

signal from a microwave receiver. This application utilizes the full functionality of BrightEye 5 by time

base correcting a noisy analog video microwave input signal and frame synchronizing it to a house

reference which is also feeding analog video devices.

Refer to the application drawing below for an example of using BrightEye 5 for this purpose.

Input and Output BNCs

There are four rear BNC connectors which are used as inputs and outputs as follows:

• Cpst In (Composite Input) – This BNC input accepts an analog composite signal, 525 or 625

line standard. The input standard is auto-detected.

Note: For applications with intermittent or low quality input signals, the video standard can

be set manually to either NTSC or PAL in the Input menu. This will improve performance

when the input signal is compromised.

• Ref In (Reference Input) – For synchronizing (genlocking) the input signal to an external

reference, connect a composite video signal (PAL or NTSC with the same line rate as the input

video) to the Ref In BNC.

• Composite Out 1 and 2 – Two timed composite outputs are provided for feeding analog

destinations. The output standard follows the input standard and must be the same standard

as the reference, if one is used.

Operation

Control and operation of the BrightEye 5 is performed from the front panel or remotely from a

networked PC with the BrightEye Mac/PC Control application software.

Note: Some control settings are only available with BrightEye PC or Mac. These parameters

cannot be monitored or controlled from the front panel.

Front Panel Controls and Indicators

The front panel of the converter, shown in the gure below, provides status and control indicators for

adjusting parameters from the front panel.

Status Indicators

• In (Input) – Illuminates green when a valid input is detected on the Cpst In BNC connector.

• Ref (Reference) – Illuminates green when a valid NTSC or PAL reference is detected on the

Ref In BNC connector.

Note: A reference is not required for operation.

• Pwr (Power) – The power indicator illuminates green when the BrightEye unit has power and

the internal voltage regulator is functioning correctly.

Adjusting Parameters from the Front Panel

Use the Mode, Right Arrow, and Left Arrow buttons to select and adjust parameters from the front

panel.

Pressing the Mode button activates the front panel for editing and tabs between each section of

editable parameters.

Pressing the Right Arrow or Left Arrow advances the selection within a given section of parameters,

or increases (Right Arrow) or decreases (Left Arrow) the value of a selected parameter.

Note: The LED of an edited parameter will blink for 15 seconds, after which time its value is

stored in memory. If power is interrupted before this 15 second timeout period has elapsed,

the edited state will not be not saved.

The controls and their indicators are described below: .

• Timing – The timing function operates in one of three modes:

1. When the TBC/Frame Sync control is turned On and a proper reference signal is

connected to the Ref In BNC, the video output of the unit will be synchronous and locked

to the external reference. The output may be timed with respect to the Ref In using the

timing controls. In this case, the unit will accept asynchronous video and time base errors

will be corrected.

2. When the TBC/Frame Sync control is turned On and no reference signal is connected,

the unit will act as a time base corrector only. The output will not be synchronous to any

reference, including the input. This mode allows a noisy analog input signal to be time base

corrected for a clean stable output.

3. When the TBC/Frame Sync control is turned O, any reference signal to the Ref In BNC

is ignored. The video input is synchronous to the video output when a nearly perfect, clean

video input signal is present (SDI or analog video with no time base correction required).

The output timing of the module can be adjusted with the following controls when the TBC/Frame

Sync is turned On:

Vert – Adjust the vertical timing in lines with reference to the Ref In.

Hor – Adjust the horizontal timing in clocks with reference to the Ref In.

Fine – Adjust the timing in subpixels with reference to the Ref In.

• TBC/Frame Sync – This control enables the Frame Sync genlock function and the timing

controls when an external reference is present on the Ref In BNC.
