ViewCast Corporation (OTCBB: VCST), a global leader in the design and manufacture of the world’s most advanced media encoding products, today announced the retirement of Horace Irwin, senior vice president of sales and business development at ViewCast as of June 30, 2007. A search for his replacement is in progress. In accordance with new business initiatives, ViewCast is aggressively moving to launch new products in new markets. "Horace has worked hard to build brand recognition and visibility for ViewCast’s Osprey and Niagara product lines,” said Dave Stoner, president and chief operating officer of ViewCast Corporation. "We appreciate all of Horace’s contributions, and wish him well in the future.” During the past year, ViewCast implemented an aggressive strategy to introduce new cutting edge products, promote existing product lines and establish strong strategic partnerships with other OEM and VAR customers such as Multicast Media Technologies. This spring, ViewCast introduced five new products including the Osprey-240, a video card that combines PCI Express compatibility with professional analog inputs to deliver high bandwidth capture for sports, entertainment, news, and other high quality content distribution, and OSPREY-700 HD high-definition video capture card.

"This is an exciting time for ViewCast,” Stoner noted. "With so many new product introductions, sales continue to grow rapidly. While we will miss Horace as the company moves into a new phase of expansion, the business relationships he helped establish will make it easier for others to follow.” About ViewCast ViewCast develops communication products for live and on demand video and audio content deliverable via a variety of network types and protocols.
