IP video deployment is no easy task

Today, we’ll continue our discussion of IP video and will share our own business experiences of IPV and how enterprise video can be useful. We’ll highlight some tips from AT&T on IPTV based on an enterprise content data network.

First some personal experiences with IPV from Larry. As an industry analyst, Larry’s work schedule includes frequent briefings, trade shows, and analyst conferences. In the past two weeks alone, Larry has noticed an uptick in the use of video where:

* One in four briefings has added a live video window over the Internet that included presenter “head shots” via a desktop Webcam, the presentation, and a chat window.
* Two PowerPoint presentations that were delivered via a WebEx screen included embedded video clips.
* Two YouTube videos accompanied separate briefings; one video was an “introduction” to the presenter and the second was a product installation demo.
* Cisco’s annual analyst conference offered the option (which Larry took) to attend sessions remotely via video feed over the Internet – saving both time and travel expense. While the audio-video feed was one-way from Cisco, the simultaneous conference application also offered the same kind of interactive features used in a WebEx meeting. The conference and presentations were also available for viewing later from a secured Web site.

To get access to the video, Larry used only his laptop connected to the Internet. As a reference point, Larry’s total network capacity demand for a typical hour-long briefing that included live video averaged about 2.8 Megabits downloaded and 0.5 Megabits uploaded over a one-hour period. And while the video quality was “YouTube” like in quality, Larry found that the video additions significantly enhanced the briefing messages and product demos.

And while video should be made easy for the desktop user, the reality of enterprise video is not so simple. AT&T recently suggested in a recent white paper that enterprises consider an “Integrated Content Delivery Networks Approach” solution for what AT&T calls “Enterprise IPTV.” In the paper, Enterprise IPTV is defined as a solution that is used to “produce and broadcast live and on demand video to internal (employees) and external (partners, customers, investors, analysts) audiences.” In the AT&T solution, the video is delivered over IP to auditoriums, conference rooms or desktops, and viewed with media players on desktop computers, or from dedicated set top boxes and multimedia appliances. The AT&T approach described here is based on an AT&T Enterprise CDN solution that uses the Cisco Application and Content Networking System (ACNS) platform, the AT&T Intelligent Content Delivery Service (iCDS) and a Jubilant ERM2 Platform for IPTV Management.
