Don’t Forget the Sound

With the addition of a DPS AS-475 or AS-575 four-channel audio syn-

chronizer module, the unit can provide dual stereo audio and video

synchronization in a single rack height package.The internal audio syn-

chronizer option supports balanced or unbalanced analog, AES/EBU

digital and embedded SDI audio I/O. All outputs are simultaneously

active, which enables both analog and digital audio devices to be con-

nected at the same time. Incoming stereo audio pairs can be selected

from the analog, digital or embedded SDI inputs. All four audio chan-

nels dynamically track the internal delay of the video synchronizer

whenever auto-track mode is enabled. Up to 1.75 seconds of total

delay can be specified, ensuring proper lip sync regardless of the pro-

gram source. All audio parameters are controlled from an easy to use

front panel menu. Four separate audio tone generators enable differ-

ent frequency test tones to be applied to each channel for easy

left/right channel identification. User-definable audio test signals or

arbitrary stereo waveforms can also be uploaded from a PC.

"Gimme Bars" Automatic Proc Amp Setup

With a known input signal (75% color bars), you can automatically and

accurately set the video proc amp controls with the press of a single

button. Manual adjustments without the use of a scope or a monitor

are also easy, since peak video levels are displayed as IRE units in real-

time.The digital proc amp controls enable the adjustment of all signal

parameters regardless of input source. This means you can even cor-

rect for color phase errors (hue) in SDI and component video streams.

For dynamic level adjustments, a switchable video AGC circuit moni-

tors sync-tip levels to continuously set video gain.

Video Framestore, Linear Keyer & Logo Inserter

An entire frame of video can be stored in the synchronizer’s non-

volatile memory. The still image can be displayed full screen or keyed

over live video. Stored images can include an associated linear key. Fill

and key information can be grabbed from live video in separate pass-

es or graphic files can be uploaded to the synchronizer using the sup-

plied Windows® software. The built-in framestore/keyer also makes an

ideal logo inserter or source I.D.generator. Multiple logos can easily be

stored in the available RAM. For even more pizzazz, animated logos

with synchronized audio are optionally available. Logo insertion can be

initiated from the front panel, from an RC-4000 remote control or via

GPI trigger. Two GPI inputs and one GPI output are standard.

DigiDuplex

™

Supports Bi-Directional Processing

DPS’ exclusive DigiDuplex feature provides bi-directional connectivity

between analog tape machines and digital routing systems.

DigiDuplex enables simultaneous transcoder and frame

synchronizer operation.DigiDuplex mode routes the syn-

chronizer’s SDI input directly to the analog video outputs

which feed the inputs of an analog tape machine. The

analog output of the tape machine can be simultane-

ously connected to one of the synchronizer’s analog

inputs where it can be processed and output via the SDI

port. Audio signals are handled in a similar fashion. DigiDuplex mode

supports both AES/EBU and embedded SDI audio.

Adjustable Digital Bandwidth Filtering

In addition to digital noise reduction, the DPS-475 and DPS-575 offer

adjustable 2D filtering with separate horizontal and vertical bandwidth

controls. For MPEG preprocessing applications, digital bandwidth filter-

ing provides entropy reduction prior to MPEG encoding.

Engineered for the Real World

The rugged yet lightweight chassis is plenty tough for mobile use.

Standard rear rack supports adjust for various rack depths and elimi-

nate the need for rack slides. The all metal front panel provides

expanded function buttons and additional status LEDs. A vacuum

flourescent graphical display (VFD) features variable sized fonts for

readability and can be dimmed to suit control room lighting condi-

tions. The VFD also provides real time audio VU meter and video level

indicators for peak luminance, minimum black and peak saturation.

Easily Upgraded in the Field

The DPS-475 and DPS-575 employ flash upgradable microprocessors

and field programmable gate arrays. Firmware updates can easily be

installed without disassembling the unit or replacing any integrated

circuits. Firmware updates are posted on the DPS web site, where they

can be easily downloaded and installed using a PC or laptop.

The World’s First Modular Pizza Box

Through the use of large-scale integration and surface mount compo-

nents, the DPS-475 and DPS-575 synchronizers offer incredible func-

tionality and I/O flexibility in a single unit of rack space. Even when

equipped with an audio synchronizer module, animated logo inserter

and DV I/O module, there is room to spare in our "pizza box" chassis.

We used that extra space for an optional expansion slot, which pro-

vides access to all of the digital I/O and memory functions of the syn-

chronizer. Optional processing cards are currently under development

that will enable the DPS-475 and DPS-575 to assume entirely new per-

sonalities. Check the DPS web site for the latest developments.
