Integrating Polycom EagleEye Director with 
an HDX and SoundStructure System 

This

 

application

 

note

 

describes

 

how

 

to

 

use

 

Polycom’s

 

EagleEye

 

Director

 

with

 

an

 

HDX

 

Video

 

conferencing

 

system

 

that

 

is

 

integrated

 

with

 

a

 

SoundStructure

 

system

 

and

 

details

 

the

 

steps

 

for

 

creating

 

a

 

SoundStructure

 

project.

 

Integrating the HDX codec and the EagleEye Director 

The

 

Polycom

 

EagleEye

 

Director

 

for

 

HDX

 

delivers

 

an

 

affordable,

 

personalized

 

telepresence

 

experience

 

in

 

group

 

meetings

 

by

 

intelligently

 

emulating

 

professional

 

video

 

production

 

techniques

 

enabling

 

better

 

communication

 

and

 

more

 

productive

 

meetings

 

 

no

 

remote

 

control

 

or

 

user

 

intervention

 

is

 

required.

  

SoundStructure

 

solutions

 

offer

 

the

 

ultimate

 

in

 

audio

 

quality

 

and

 

flexibility

 

for

 

any

 

size

 

room.

  

Combining

 

these

 

components

 

together

 

is

 

a

 

natural

 

extension

 

of

 

the

 

HDX

 

codec

 

and

 

improves

 

the

 

overall

 

audio

 

experience.

 

As

 

shown

 

in

 

Figure

 

1,

 

when

 

the

 

EagleEye

 

Director

 

is

 

used

 

with

 

an

 

HDX

 

codec,

 

the

 

two

 

systems

 

are

 

connected

 

together

 

with

 

a

 

custom

 

cable

 

included

 

with

 

EagleEye

 

Director

 

that

 

connects

 

the

 

audio

 

outputs

 

(1L

 

and

 

1R)

 

from

 

the

 

HDX

 

codec

 

to

 

the

 

EagleEye

 

Director

 

and

 

connects

 

the

 

same

 

audio

 

to

 

the

 

Amplifier

 

via

 

additional

 

balanced

 

audio

 

cables.

  

In

 

addition

 

to

 

the

 

audio

 

cables,

 

there

 

is

 

a

 

video

 

cable

 

(red

 

in

 

this

 

figure)

 

for

 

taking

 

the

 

video

 

output

 

from

 

the

 

EagleEye

 

Director

 

into

 

the

 

HDX

 

codec.
