PRODUCT OVERVIEW

BrightEye 75 converts standard definition analog component or composite video,

or high definition analog component video to SDI with simultaneous conversion of

two channels of audio and embedding. A TBC/Frame Sync is a standard feature

and allows the BrightEye to work with any type of video input.

BrightEye 75 is versatile enough to handle applications from broadcasting to

desktop video with sources such as VTRs and incoming satellite feeds.

Basic controls are accessed on the front panel. The BrightEye Control application

provides access to video proc functions, input and output, and built-in audio mixer

controls that are not available from the front panel.

FUNCTIONAL DESCRIPTION

As shown in the functional block diagram below, analog video is converted at

14 bits of resolution and digitally decoded to YCrCb components (601). The signal

is then time base corrected and frame synchronized to the reference input. Proc

amp adjustments are provided for the converted video.

The audio is converted to digital and then passes through the built-in 2-channel

mixer with shuffle and level control.

The video and audio signals are joined in the embedder. This embedded signal

passes through a serializer to an SDI output on the rear of the unit.

BrightEye 75 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.

It 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

The BrightEye 75 is well-suited to applications using HD Cameras or other

devices with analog I/O. The built-in TBC/Frame Synchronizer allows you to feed

asynchronous or noisy signals to the BrightEye 75. These are then digitized and

time-base corrected by noise-tolerant tracking circuitry.

The example below shows a three-camera, live studio setup. Full bandwidth

analog video from an HD camera is fed to a BrightEye 75 and converted to HD SDI

digital video. The signal is time base corrected and frame synchronized to the

reference input. The signal is then sent to a Production Switcher and out to live

broadcast.

The analog audio from the cameras enters the BrightEye 75 two-channel

AtoDconverter.Adjustmentsforaudiomixing,audiolevels,andchannel

shuffling can then be applied to the audio before it is embedded into the SDI

output signal and fed to air.

BrightEye 75 - Page 13

Timing Menu

Use the Timing Menu to set the parameters of the TBC and Frame Sync

functions. The timing function operates in one of three modes:

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

is connected to the Ref In BNC, the video output of the unit is 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 Frame Sync control is turned On and no reference signal is

connected, the unit acts as a time base corrector only. The output is not syn-

chronous to any reference, including the input. This mode allows a noisy

input signal to be time base corrected for a clean, stable output.

3. When the Frame Sync control is turned Off, 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 (no time base cor-

rection required).

The following timing control is available when the Frame Sync function is On:

•Timing– adjust the vertical and horizontal timing of the signal with

respect to the reference input. Click the Default button to return to the

default value.

Use the following control to enable the Frame Sync function:

•FrameSync– set the Frame Sync function to On to genlock to the

reference input to the module, or to Off for no Frame Sync.

Config Menu

Use the Config menu to set the following output conditions for the output signal:

•SignalMute– select the condition for muting the output signal to

No Muting, Mute On Noise, or Freeze on Noise.

•AnalogSetup– set to On if setup is present on the analog input, or Off if

no setup is present.

•VBlanking– set the vertical blanking to Narrow (NTSC: lines 1-9,

PAL: lines 1-6) or Wide (NTSC: lines 1-20, PAL: lines 1-22).

•CombMode– set the comb filtering to Comb On or Comb Off.

•PeakIndicator– selects the amount of headroom used in determining

peak indication. Chose Clipping,2 dB Headroom,4 dB Headroom,

GLOSSARY

This is a brief glossary of commonly used terms associated with this product.

AES/EBU

The digital audio standard defined as a joint effort of the Audio Engineering

Society and the European Broadcast Union. AES/EBU or AES3 describes a serial

bitstream that carries two audio channels, thus an AES stream is a stereo pair.

The AES/EBU standard covers a wide range of sample rates and quantizations

(bit depths.) In television systems, these will generally be 48 KHz and either 20

or 24 bits.

Bandwidth

Strictly speaking, this refers to the range of frequencies (i.e. the width of the

band of frequency) used by a signal, or carried by a transmission channel.

Generally, wider bandwidth will carry and reproduce a signal with greater

fidelity and accuracy.

Beta

Sony Beta SP video tape machines use an analog component format that is

similar to SMPTE, but differs in the amplitude of the color difference signals. It

may also carry setup on the luminance channel.

Blanking

The Horizontal and Vertical blanking intervals of a television signal refer to the

time periods between lines and between fields. No picture information is trans-

mitted during these times, which are required in CRT displays to allow the

electron beam to be repositioned for the start of the next line or field. They are

also used to carry synchronizing pulses which are used in transmission and

recovery of the image. Although some of these needs are disappearing, the

intervals themselves are retained for compatibility purposes. They have turned

out to be very useful for the transmission of additional content, such as teletext

and embedded audio.

CAV

Component Analog Video. This is a convenient shorthand form, but it is subject to

confusion. It is sometimes used to mean ONLY color difference component

formats (SMPTE or Beta), and other times to include RGB format. In any case, a

CAV signal will always require 3 connectors – either Y/R-Y/B-Y, or R/G/B.

Checkfield

ACheckfieldsignalisaspecialtestsignalthatstressesparticularaspectsof

serial digital transmission. The performance of the Phase Locked-Loops (PLLs) in

an SDI receiver must be able to tolerate long runs of 0’s and 1’s. Under normal

conditions, only very short runs of these are produced due to a scrambling

algorithm that is used. The Checkfield, also referred to as the Pathological test

signal, will “undo” the scrambling and cause extremely long runs to occur. This

test signal is very useful for testing transmission paths.
