Technology moves ahead….
and keeps moving ahead….
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?
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
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….
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/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 Experience
Only 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
THANK YOU
Video 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?
NAT Avoidance


Uses techniques to avoid a firewall / NAT
May require additional CPE
NAT Traversal


Video calls traverse the firewall / NAT
Multiple methods available
One approach – Avoid the NAT problem

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)
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 – Traversal 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 Server
H.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)
V2IU Traversal Server
Mobile user registers
with TS and calls host
location using alias.
IP Cloud
Polycom can provide a hybrid solution
Outside user
does not have to
register with
Traversal Server
