Wide Range of Choices

Product range from Telepresence to Desktop Video

Infrastructure Requirements differ for each choice

Service Components – Build versus Buy

Connecting through the IP Network

Integration with Unified Conferencing

Legacy connectivity

Business to Business Video Conferencing

Define the Application

What business process can benefit from video

conferencing?

What are the characteristics of this application? Conversations within the enterprise or outside the enterprise?

Are meeting members meeting for the first time or do they already

know each other?

Executive meetings? Team collaboration?

Will there be shared materials? Is this material on computers or is it

physical in nature?

Short meetings or long meetings?

Is the meeting space environment conducive to video conferencing?

(lighting, acoustics, noise level, stability)

Is a high bandwidth network available?

5


Different Requirements,

Different Solutions

Simple data

sharing

Low meeting fatigue Perfect eye contact

Ease of use

Room system

compatibility Low BW demand

Immersive experience

6


Return on Investment

Video conferencing is usually justified based on travel

reduction Travel reduction savings occur best with a top-down mandate

These savings can be real and can generate a 12-month ROI

The real value comes from improving business

processes: Allow more team members to ‘meet’ and establish relationships

across distance without travel

Connect more in-house ‘experts’ to in-house problems or to partners

/ customers / vendors

Speed up development or marketing processes, get to market faster

Improve the quality and speed of cross-company programs through

more frequent and higher quality interactions

Telepresence – What is it?

Special purpose conference room dedicated to video

conferencing meetings

Participants in the room face the video participants across a

‘common’ table

Immersive technology

Multiple cameras and screens for wide angle view

Life size (HD) images of remote participants

‘Common’ table

Careful lighting and acoustics

design

Stereo sound for directionality

Eye contact (camera

placement)

Simple to use

10


Room-Based Video Conference

HD Video is the underlying codec technology in

Telepresence

I define HD Video Conferencing as single codec

systems that use HD resolution

Some vendors label this ‘Telepresence’ as well

11


Room-Based Video Conference

Systems designed for a conference room

Systems have an optional second display for data

sharing content

Older systems use standard definition (CIF or 4CIF)

Newer systems have HD resolution (720p or 1080p)

Room systems come in

different packaging: Lecture hall / auditorium

Conference room

Rolling carts

12


Executive Desktop & Videophone

Integrated systems intended for executive

desktop use

Systems often double as additional PC

display

Desktop video phones intended to replace

telephone as well

Decide: Compatibility with telephony system?

Compatibility with room and

telepresence systems?

Who are you communicating with?

13


Desktop Video

Many vendors with proprietary

solutions Each creates a video island

Skype, Visimeet, ooVoo, Vidyo,

Google

Interoperable versions exist Polycom, Tandberg, RadVision,

Avistar

Images are smallWide angle lens – short distance

Environment is uncontrolled

Single person image may work

well for your application Pixels per face is high

14


Peripherals

Document cameras

Smart boards

Special application devices Medical instrumentation

Remote equipment debugging

Projectors

What are the specific needs for

your application?

Drive the decision process

based on solving a real

business need

15


Environment

Audio & Video environment must be managed

All these can ruin a video conference Poor lighting

Noise

Poor echo cancelation

Lessons of Telepresence Face the screen

Pixels per face

Lighting faces

Excellent audio is mandatory

Don’t put a video system at

the end of a boardroom

table – it doesn’t work!

16

High contrast (windows, direct sunlight)

Distracting background

Small images (too many people / screen)


Quality, Power, Bandwidth

17

Increasing resolution, frame rate & quality increases bandwidth

demand

Increasing power of video compressor decreases bandwidth

Transport vs. Signaling

Transport (Media) How video conferencing video and audio is carried between

endpoints

Most current implementations using IP network or moving to IP

network in the near future

Video/audio connects directly from endpoint-to-endpoint or

endpoint-to-bridge based on IP routing

Signaling How video endpoints find each other on the network to set up a call

Signaling options: Stand-alone videoconferencing

IP-Telephony-based

Unified Communications-based

Cloud (service) based

20


Enterprise Client-Server

Infrastructure resides

within the enterprise

Video is a stand-alone

communications solution

Call control managed by

H.323 gatekeeper or SIP

server

Local dialing plan

Often support remote workers

via VPN connections

Gateways required: Cross firewall for B2B calling

PSTN integration for ISDN video and for PSTN telephony integration

Capital $$$ investment, lower cost of operation

The Network

There is one more key component of the video

infrastructure, the Network!

Transporting video conferencing is a learning

experience Has all the real-time issues of VoIP

Plus it has an insatiable thirst for bandwidth

Ensure your network team is an integral part of the

video conferencing discussion

Determine network requirements for the video

conferencing deployment Transport bandwidth demand

Quality of Service needs

Service Level Agreement

25


Converged or Overlay Network?

Overlay – Separate network

carries video traffic

Isolates bursty data traffic

from voice & video

Simple to design and configure

Allows rapid and successful video deployment

especially for high visibility telepresence systems

Can be migrated back to converged over time

Converged Network Solution

Converged – All data,

voice & video on the

same corporate network

Provides best long-term

cost and manageability

Difficult to get it right

Requires new understanding about traffic support,

tools, QoS and bandwidth management

Will be a requirement for desktop-based video

Service Strategies

28


Understand your customer

Align the service with customer requirements

Define your enterprise service offering

Service features and service levels

Secure corporate sponsorship and budget

Deploy and manage the right technology

Endpoints, transport infrastructure,

media services, management platforms

Build an effective delivery organization

Centralized and remote support team

Skills and experience

Focus on Service Level Management

Quality-of-Experience, Capacity Utilization,

Cost Efficiency, Business Value

Manage to targets; proactively measure and report results

Your Role as Service Manager

29


Managed Services Providers can help

Most infrastructure components can be

outsourced via network links

Service providers bring a wealth

of knowledge about managing

a video conferencing environment

May have specialized tools for support of

video conferencing environment

Scheduling, billing, reporting

Small deployments benefit from concentrated

knowledge base of service provider

Think through bandwidth issues before outsourcing MCU to a

service provider Hosted – Service provider owns bridge, charges per call, needs high BW connection

Managed – Enterprise owns bridge, service provider manages, bridge located in enterprise

network
