Keynote to Reveal Findings of First-Ever Performance Monitoring Study of Streaming Video Quality at Top User-Generated Video Web Sites

Keynote (Nasdaq:KEYN), The Mobile and Internet Performance Authority™, today announced that it will reveal the findings of its first-ever performance monitoring study of streaming video quality at popular user-generated video (UGV) Web sites including YouTube, Yahoo! Video, Revver, MetaCafe, Grouper and others during an upcoming Webinar. The Webinar will take place on Thursday March 8th, 2007 at 11:00 AM Pacific (2:00 PM Eastern) and is produced by Streaming Media magazine and StreamingMedia.com. In addition to revealing the results of the UGV performance monitoring study, the experts from Keynote and AccuStream will identify the companies that are succeeding in this highly competitive space, illustrate why and how they are doing it, and provide insights into which sites are the best bets for both content and advertising. Leading the discussion will be Jeff Geiser, global director of streaming media at Keynote and Paul Palumbo, research director for AccuStream iMedia Research. Eric Schumacher-Rasmussen, Editor-in-Chief of Streaming Media Magazine will moderate the online event. The Webinar will also cover the following topics: Analysis of the types of content that draw the most eyeballs; UGV advertising metrics and what drives views; How technical factors — connect time, buffer time, latency, availability, and more — affect video site performance; and What does it all mean for advertisers and content publishers who leverage these sites? The Keynote study of user-generated video Web sites, the first of its kind, monitored the stream quality of the top-rated video at 20 of the leading Web destinations for user-generated video (including UGV specialists, such as YouTube and Revver, as well as portal players like Yahoo! Video) using Keynote’s Streaming Perspective™ streaming quality test and measurement solution. Measurements took place from Jan. 1st to Jan. 31st, 2006 with a total of 230,000 total measurements taken over the course of the study. Keynote then assessed the performance of those streams based on metrics that include availability, connect time and buffer time. Performance measurements were taken from 14 cities worldwide, with bandwidth limited to 500kbps for all sites/streams to provide a level playing field. Streaming Perspective is a commercially available on-demand service that measures the quality and reliability of streaming media delivery the way users experience it. Streaming Perspective is an extremely effective early warning system for alerting key stakeholders to service availability issues or user experience deterioration, allowing them to measure the quality and reliability of audio and video streams from multiple geographic locations around the world, all from the end-user perspective. It is used by major Content Delivery Networks (CDNs) and Fortune 500 companies to measure and improve the quality of their streaming media delivery. "User quality of experience will increasingly become a key factor in determining which UGV sites are able to maintain high levels of user adoption and retention,” said Jeff Geiser, global director of streaming media and VoIP at Keynote. "Content producers and advertisers will similarly evaluate the quality of delivery when choosing distribution channels for their content and advertising campaigns." User-generated video hosting and distribution sites have emerged as viable outlets for individuals, as well as semi-professional and professional content producers over the past two years. UGV sites have also expanded to include branded content channels from rights holders such as CBS, NBC and others creating unique identities in UGV environments. UGV views totaled over 30 billion in 2006, up over 450% from 2005, according to AccuStream iMedia Research. The segment is gaining additional momentum now that high production value content from rights holders and advertisers is entering these libraries. Further, with abundant metadata produced during engagement of UGV content, there is a new opportunity to carve out performance-driven advertising value from this rich back channel. "User-generated video is evolving quickly into both a lean forward and lean back experience,” noted Paul A. Palumbo, research director with AccuStream. "Much like the medium itself, audiences are getting more sophisticated — and quickly. They are browsing UGV libraries in rapid discovery mode to seek out what might be enjoyable, but also searching for specific files of interest and then hitting play, including longer form content. In both orientations, performance matters. UGV is about the community, and the community’s visual voice. With libraries containing millions of files, it is incumbent on these sites to ensure experiences that fully enable the experience of finding what is entertaining.” To find out more and to register for the Webinar, interested parties are directed to visit: http://www.streamingmedia.com/webevents/details.asp?eventid=207&src=kn 10 (Due to its length, this URL may need to be copied/pasted into your Internet browser's address field.
