ViewCast Introduces ViewCast Online EZStreamSM at NAB2001

End-to-End Streaming Solution Puts Streaming Content on Business Web Sites with No Hassles

DALLAS(April 24, 2001) – Putting streaming video on a corporate Web site is now as easy as point-and-click with EZStreamSM, a complete streaming media service for businesses from ViewCast Online, a division of ViewCast Corporation (NASDAQ: VCST), a leading provider of Internet and networked video solutions.

EZStream will be demonstrated April 23-26 at NAB2001 in Las Vegas (Booth E2905 in the lower level of the Sands Exposition Hall), and will be available from the company’s new video solutions portal www.viewcastonline.com on April 30.

According to Jupiter Media Metrix, business use of streaming video is forecast to grow from $140 million to $2.8 billion by 2005.

“The types of new tools, packaged products and end-to-end support offered by ViewCast Online are essential for businesses to take advantage of the benefits of Internet video and for the market to reach its potential,” said John Caulfield, president of ViewCast Online Solutions. “ViewCast Online makes Internet video easy for small to mid-size businesses that might not have the time, resources or necessary skill sets to incorporate this effective new communications medium into their web site.”

EZStream combines software and specially packaged services that enable businesses to capture, edit, encode, publish, host and deliver streaming video/rich media content on corporate Web sites. With EZstream, communicating via video online is as easy as click, create and view.

Prior to the introduction of EZStream, getting video on the Internet involved a multitude of separate steps – everything from capturing, encoding, and editing video to setting up streaming servers, intricate Web site coding and negotiating for favorable bandwidth rates. EZStream from ViewCast Online automates the entire process into a single, point-and-click procedure performed directly from the company’s web site (www.viewcastonline.com).

EZStream processes the video and publishes it to ViewCast Online’s high-performance content delivery network. The business need only paste a provided link onto its Web site for any visitor to view. EZStream also enables businesses to click-and-create content from scratch and then publish their content.

Managing accounts is equally simple. Business clients can change or renew hosting rate plans, change account profiles and set up or change e-mail notification flags for traffic and usage metrics information and alerts.

“Businesses have known ViewCast for streaming video expertise and streaming capture cards from Osprey Video,” said Caulfield. “Now businesses can come to ViewCast for a complete end-to-end streaming solution – from hardware to software, and services.”

ViewCast products also appear in the Hitachi (Booth L6414), Microsoft (Booth I5921) and RealNetworks (Booth I6726) booths at NAB2001. The company will be giving away popular Osprey-210 audio/video capture cards at all locations. In addition, ViewCast will hold a drawing during the show for a Niagara Streaming System at the ViewCast booth.
