W h i t eP a p e rPersonal Video ConferencingHow mobility is changing the video conferencing landscape:Industry trends and deployment best practicesExecutive SummaryPersonal video conferencing can be defined as theuse of video conferencing software on a personalcomputer, tablet or smartphone or, more generally,without additional, dedicated equipment. It contrastswith “room video conferencing,” where participantshave to move to a dedicated conference roomequipped for video conferencing.In the last few years, personal video conferencingSales of tablets, as a whole (consumer andenterprise), will grow at a CAGR of 75.6%to reach 294 million units by 2015, withApple expected to maintain the largestmarket share with its iPad line(see “Forecast: Media Tablets by OperatingSystem, Worldwide, 2010-2015”).became part of the daily processes and communicationroutines within companies and organizations ofevery size and in every industry, all over the world,Gartner says that more than 130 million workerscomplementing—and in some cases replacing—worldwide will use corporate-supplied videotraditional room systems.conferencing on their desktops or mobile devices by2015, compared to 7 million in 2008, while spendingPERSONAL VIDEO CONFERENCING DEFINITIONThe use of video conferencing on a personalon dedicated soft clients will grow at a compoundannual growth rate of 22.9% by 2015.1computer, tablet or smartphone without theThis white paper analyzes the latest trends in personalneed for additional, dedicated equipment.video conferencing, including the benefits, some casestudies and the best practices for its deployment.1 Gartner, Market Trends: Videoconferencing, Worldwide, 2011, 28 April 2011Personal Video Conferencing3

W h i t eP a p e rPersonal Video ConferencingApplications & BenefitsThe applications for video communications areendless, and when video conferencing is properlydeployed, it tends to supplement or replace businessmeetings, educational trainings and other formsof communication. Video conferencing via mobileand personal devices, instead of holding traditionalmeetings and events, takes advantage of the greatestbenefits of all forms of video conferencing: travel costsavings and increased productivity.Certain applications, however, are unique to videoconferencing on personal devices due to theand smartphones perfectly embody the concept ofconducting business anywhere.Simplicity and flexibilityPlacing a video call shouldn’t be any more difficult thanmaking a phone call. With personal video conferencing,users can take advantage of the power of video fromany device they’re familiar with, including laptops andsmartphones.Scalability and manageabilityAdding new users to a personal video conferencingsystem requires only a software client and credentialsto be provided to anyone who needs them; it does notunmatched benefits it provides in terms of mobility,require new hardware or time-consuming setups.simplicity, flexibility, scalability and manageability.Moreover, customers are finding new, innovative waysto use personal video conferencing every day. See theMobilityWhile traditional video conferencing equipmentchart below for a selection of applications.cannot be moved from dedicated rooms, tabletsCHART 1 Personal Video Conferencing ApplicationsApplicationDescriptionMobile andremoteworkforceNine out of 10 employees don’t work at corporate headquarters, and even the ones who do are oftenon the road. Having the opportunity to join meetings from an airport lounge, a hotel room or even a cardecreases idle time and increases productivity during business travel.Meet on the flyEveryone can easily engage in an ad-hoc meeting with a remote colleague working on the same projectand get critical information on the fly without needing to book a room or use dedicated equipment.RecruitingVideo interviews are a great substitute for face-to-face meetings, and they reduce not only travel expensesfor suitable candidates but also the time involved in the recruiting process. Candidates are not likely to havepersonal conference rooms or the willingness to pay for one, but they are likely to have a laptop or a tabletthat they can use to join the video conference.ManufacturingThanks to the extreme versatility of mobile devices, performance inspections can be conducted on aremote production site without flying in an engineer or technician.Elderly careVideo conferencing can be used to provide elderly care services, including video connections to hospitals,emergency centers and relatives. Refer to Case Study A.DistancelearningNot every school can afford dedicated video conferencing equipment. Thanks to personal videoconferencing, any tablet or desktop with a webcam can turn a classroom into a video conferencing roomwith guest lecturers from anywhere joining students. Refer to Case Study B.Personal Video Conferencing5

W h i t eP a p e rCASE STUDY AElderly Care ServicesA Dutch services company needed to extend itsoffering to a larger number of customers and serviceproviders.The company offers its services through an interactiveportal featuring a range of different services, fromvideo conferencing and video on demand to homeautomation function, and its biggest challengewas interoperability among different videocommunication standards.“Even if some enterprises such as hospitals and majorcare institutions use H.323 systems and are willing toinvest in expensive video conferencing infrastructure,the possibility to interact with their customers relieson the capability to interoperate with SIP-basedclients, said the company’s ICT technical consultant.Thanks to the addition of LifeSize ClearSea to itsportal, the company has enabled its subscribers toconnect with their peers, caregivers and relativesthrough easy-to-use devices, such as touch-screentablets on their existing Internet connections.The company is now involved in the development ofan elderly-care project that will allow each customerto have a personalized and dedicated range of services,including video connections to hospitals; emergencynumbers of relatives; and on-demand video contentregarding self-medication, bank/insurance productsand home functions.CASE STUDY BDistance LearningEducational Service Centers assist schools in providingquality products and services that improve studentperformance while decreasing costs. This case studyfocuses on one region’s ESC.The center adopted video conferencing to deliverdistance learning to classrooms beginning in theearly 1990s, but it was working with many schooldistricts that had limited broadband Internet accessand limited funds to acquire video conferencingequipment. As a result, they couldn’t participate fullyin many of the academic, remediation and enrichmentprograms offered through the center’s statewideeducational network.LifeSize ClearSea offered the center a turnkey solutionthat fits its needs, as it provides a standards-compliantvideo solution that can utilize schools’ existingnetworks as well as 3G/4G to allow existing devicesto connect with any H.323 or SIP video solution.With LifeSize ClearSea, rural-area schools can turntheir existing PCs, Macs, smartphones and tablets(Android and iOS) into video endpoints, improvingtheir efficiency with video conferencing and enablingthem to participate in programs they had difficultyconnecting to before, all without having to buydedicated appliances. The coordinator of distancelearning programs said that after only a month, atleast five new elementary classrooms were able toparticipate in programs that they had never hadaccess to before, and new requests for access hadbegun to pour in from all over the region.Employees of the center have also been able toconnect to ongoing conferences from the palmsof their hands and have even used the videoconferencing solution to stream a regional meetingto a half dozen schools.Schools in the region also plan to use LifeSizeClearSea to allow some of their engineeringstudents to participate in “Ask the Expert” eventsvia video conference.Other applications are being found all the time.Administrators who used to view only streamedmeetings to avoid having to travel to videomeeting rooms now interact in real time usingLifeSize ClearSea, improving both participationand productivity.Personal Video Conferencing6

W h i t eP a p e rKey Requirements for an EnterprisePersonal Video Conferencing SystemThe fact that video conferencing has now becomeeasier to use shouldn’t prevent companies fromcarefully analyzing how the technology best fits intotheir existing environments, focusing on what makes ita high-value choice and a key asset for the company.integrate with existing infrastructure.
