 Microspace          Communications and DTV Plus Broadcast IP Over HDTV at mCast 2000
         
         Raleigh,          N.C. — Microspace Communications          Corporation, provider of satellite-based video and high-speed data          networks for businesses; and DTV Plus,          provider of datacasting via digital television and satellite-based technologies,          will be participating in the Multicast Splash project during the mCast          2000 event at the San Francisco Airport Marriott, February 7-9, 2000.          
During the mCast event,          Microspace Communications will demonstrate streaming IP multicast content          via satellite into Cisco’s IP/TV player. In addition, for the first          time in history, an IP Multicast stream will be sent over a combination          of satellite and digital television signals via Microspace and DTV Plus.          
DTV Plus is one of          the first vendors to showcase its ability to multicast IP content, using          satellite and DTV signals via the Center for Datacasting Innovation (CDI)          which was formed by Intel and KICU in Silicon Valley, CA. “We are excited          about being the first company to combine satellite and digital television          datacasting to deliver web files and streaming video via IP multicast,”          said Sam Matheny, Vice President and General Manager of DTV Plus. “This          combination provides content producers with broadband reach not possible          until now.” 
The mCast 2000 (IP          Multicast Summit) event is focused on the technologies, business and management          of Multicast in IP networks. The Multicast Splash project is a demonstration          of “multicast in action” by members of the IP Multicast Initiative. According          to Joe Amor, Vice President and General Manager of Microspace, “IP          Multicasting over satellites is ideal for broadcasting to large geographic          distribution. IP Multicasting over High Definition Television is an exciting          broadcasting medium for more local distribution. We are delighted to be          showing how these two distribution mediums complement each other.”          
IP Multicast is an          open, IETF standard that enables efficient bandwidth usage for applications          that distribute data to multiple recipients. Unlike traditional bandwidth-hungry          “unicast,” which creates a separate, point-to-point data stream between          the sender and each receiver, multicast sends a single stream of data          that can be accessed by any recipient desiring the information. 
DTV Plus is devoted          to developing and deploying a nation-wide datacasting network using satellite          and digital television technologies to deliver on its vision. Microspace          provides a reliable and economical point-to-multipoint satellite broadcasting          solution for delivery of digital video and high-speed data. The Microspace          network is the largest of its type in the world and totals over 300,000          remote sites, internationally.
