Technology moves ahead….Technology moves ahead….

and keeps moving ahead….and keeps moving ahead….

High Definition is Here!High Definition is Here!

Manufacturers in every part of the video industry are

embracing the concept and standard of HD

But for an interactive application like video

conferencing, HD is more than just a resolution

Why does UltimateHD matter?Why does UltimateHD matter?Organizations are facing incremental communications challenges:

Globalization, mergers/acquisitions and outsourcing/offshoring

Travel restrictions/security, cultural/language differences, workforce mobility and telecommuting

UltimateHD enhances every communication allowing customers to:

Make informed decisions…faster

Experience every critical detail…perfectly

Share their complete work…demonstrate their full value

Enhanced communications delivers the competitive edge

Reduce product development cycle and speed time to market

Increase collaborative teamwork and efficient knowledge sharing

Improve relationships across the organization and extended teams

Leverage resources and increase profitability

What are the benefits of UltimateHD?What are the benefits of UltimateHD?

High definition is only a measure of image resolution

UltimateHD is an experience!

Polycom HDX improves each communication experience in

every way with UltimateHD HD Voice allows you to distinctly hear every sound you need to

hear and none that you don’t

– Eliminating conference fatigue while adding richness and clarity to each voice and audio input

HD Video provides the sharpest, clearest images in vivid, natural color and full motion

– Never miss a single expression and savor every detail

HD Content allows you to share your work in any application

– From PC screens to HD doc cams and DVD players your value will come through in perfect detail and full motion

UltimateHD is for….UltimateHD is for….

Organizations committed to faster time to market,

gaining a competitive edge, and saving valuable

resources

Organizations that work globally over distance and/or

interact with global customers, vendors or partners

Organizations that value the power of clear

communication and leverage that as a key asset

Organizations that see the benefits of technology as a

way to enhance their productivity as well as encourage

and reward their employees

Design/ManufacturingDesign/Manufacturing

Current Challenges: Dispersed project groups In person meetings are, at times, the only option Communicating with vendors and suppliers

Benefits of UltimateHD: Enables disperse groups to work together to accomplish

tasks faster, easier and with more synergy Share even the smallest details over HD Increase time to market and gain competitive edge

Polycom RPX Telepresence ExperiencePolycom RPX Telepresence ExperienceOnly true immersive telepresence solution that is

standards-based and interoperable with traditional video

conferencing

Highest quality audio and video in a truly immersive

environment

Seamless visuals and

transparent technology

make this the best

immersive experience

in the market

Video over IP Deployment ChallengesVideo over IP Deployment Challenges

Existing networking infrastructure is not “media-aware” Firewalls block Media (Video/Audio) calls Network Address Translation (NAT) breaks addressing Video/Audio and data traffic on shared WAN pipes degrades

voice and video quality

User Concerns Dialing concerns How do I call them? What should I dial?

– Do I have to register with them?

– Why can’t they call me?

Designing around the above problems is difficult and

expensive with legacy CPE hardware

How do you fix the problem?How do you fix the problem?

NAT Avoidance Uses techniques to avoid a firewall / NAT May require additional CPE

NAT Traversal Video calls traverse the firewall / NAT Multiple methods available

Application Layer Gateway (ALG) Decentralized solution Enables a firewall to become media aware without compromising

security

H.460 Based Traversal ITU defined NAT/FW traversal method Centralized solution Service provider model Works with legacy firewalls

Application Layer Gateway (ALG)Application Layer Gateway (ALG)

Resolves Network Address Translations issues

Media and protocol aware Preserves all features (Encryption/Content Sharing)

Uses Stateful Packet Inspection Dynamically opens and closes ports

Provides topology hiding to protect the H.323 Components

(endpoints, bridges, gatekeepers) and data devices

Application Layer Gateway (ALG)Application Layer Gateway (ALG)ALG Pros Security (intrinsic Firewall)

– Dynamic Port utilization for call duration

Scalable - Enables Shortest Path Media Routing Less costly – no extra bandwidth Ideal for “fixed” video installations Video endpoint registration not mandatory Flexible dialing Works with any endpoint

ALG Cons Not practical for mobile work force

H.460 – H.460 – Traversal of H.323 across NATs and FirewallsTraversal of H.323 across NATs and Firewalls

H.460 ITU Standard Extension to H.323 Developed by Polycom, Radvision, Tandberg Approved August 2005

H.460 enables H.323 signalling and media to traverse

NAT/FW installations

Utilizes a Traversal Server (TS) at a central location

Requires H.460 aware endpoints to register with Traversal

Server (Polycom V/VSX Series Version 8.5 available now)

H.460 – Traversal ServerH.460 – Traversal ServerH.460 Pros Allows for IP calling with legacy firewalls

– IP and Port issues resolved at Traversal Server

Simplistic for registered H.460 endpoints Ideal for mobile users (road warriors / hot spots / home

users)

H.460 Cons Extra bandwidth may be needed at Traversal Server

location Requires endpoints to register with the Traversal Server Scalability - all traffic routed through the host location

(signaling and media) Less Secure (Traversal Server may not be a Firewall)

V2IU in Traversal Server Mode (H.460)

IP Cloud

Mobile user registers with TS

and calls host location using alias.
