1WELCOME TO HD3000
The HD3000 is a high-quality set-top conferencing system combining
videoconferencing, streaming video, and multipoint conferencing. The HD3000
provides several distinctive attributes and features which makes it an ideal solution
for many group videoconferencing environments.
The HD3000LT includes the same features of the HD3000, except for the
embedded MCU and streaming capability. The HD3000LT provides ideal solution
for organizations which already have already integrated multipoint conferencing
and streaming equipment on their networks.
In this User’s Guide, the term “HD3000” relates to both models, unless
specifically noted otherwise.

1.1 HD3000 Features
Feature HD3000 HD3000LT
TV-like video and crisp audio quality
HD3000 includes Emblaze VCON’s award-winning
technology and solutions for maintaining high quality
during video, audio and control transmissions. It
supports H.261, H.263, H.263+, H.263++, H.264, and
60 bps interlaced video mode. It also supports G.711,
G.722, G.723.1, G.728 and G.729 audio transmission.
Features such as Automatic Buffering, Automatic Lip
Synch Enabling, and Acoustic Echo Cancellation
(AEC) provide superior performance.

Variety of Single and Dual Display
Configurations
The HD3000 supports various single and dual
monitor setups of TV-type and VGA-type monitors
(VGA, XGA, SVGA). The dual TV and XGA+TV
configurations allow the streaming of People and
Content video using H.239 or DuoVideo technology.
In a dual monitor configuration, one monitor (TV or
VGA-type) displays the remote video and the other
monitor (TV) displays local video and the system
interface.

Emblaze VCON HD3000 User’s Guide 3
Multipoint Videoconferencing Through an
Embedded MCU
An embedded 4-port Multipoint Control Unit (MCU)
provides robust but easy-to-use multipoint
conferencing capabilities. Users can initiate and
control the Chair of multipoint conferences,
participants may receive the floor temporarily, or an
administrator can set up a dial-out conference,
instantly connecting all parties. The HD3000
implements audio and video transcoding which
enables all participants to receive the optimum
conference quality supported by their systems.
Additionally, the HD3000 employs speed matching,
allowing all participants to connect at different
speeds, as supported by their systems.
---
System and Call Security
Administrators may restrict access to the system’s
configuration, prevent unauthorized outgoing calls, or
lock the system completely.
The HD3000 supports the H.235 protocol, which
provides secure signaling, video and multimedia
communications in an H.323 conferencing
environment.

Quality of Service (QoS)
Emblaze VCON’s PacketAssist™ Architecture
preserves optimum quality of your videoconference
according to available bandwidth and network traffic.
The HD3000 applies mechanisms such as IP
Precedence to prioritize the video, audio and control
bits, and DiffServ to transfer packets according to the
HD3000’s specific needs.

Multicast and Unicast Streaming
The HD3000 applies HD Simulcast™ technology,
which provides multiple ways of streaming live
conferences out over your organization’s network and
over the Internet, where it can be viewed by any
authorized person with a streaming viewer. Users can
simultaneously stream a presentation and live video to
remote sites. The streaming functions may be
accessed through the HD3000’s Web-based
Management, allowing network administrators to
begin and end streaming, freeing the conference
leader (Chair) to control the meeting. H.239 support
enables video and data streams to appear in separate
windows on other systems that also support H.239.
---
Participation in Interactive Multicast
Using Emblaze VCON’s Interactive Multicast, all
parties in the videoconference see and hear the same
video, audio, and data sharing. HD3000 users may
temporarily receive the floor, in which their video and
audio are seen by the other parties until the floor
returns to the session’s controller (Chair).

Remote Management Through a Web
Browser
From any computer on the same network as your
HD3000, several functions may be accessed through
Microsoft® Internet Explorer.
