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

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

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)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.
