C-COR To Show Live Demos of 10 GigE Optical Packet Digital Video Delivery and Edge QAM Processing at Cable-Tec Expo.

STATE COLLEGE, Pa. -- Will Feature Delivery of HDTV and Other Digital Services Over Advanced Transport

C-COR.net Corp. (Nasdaq:CCBL) will demonstrate the latest advances in its end-to-end digital video delivery solutions at the 2004 SCTE (Society of Cable and Telecommunications Engineers) Cable-Tec Expo (Booth #856), June 16-18, in Orlando, Florida. C-COR will show live demonstrations of four key areas of digital transport:

--Delivery of HDTV content over 10 Gigabit multi-service packet transport for standard and high definition audio/video, high-speed Internet, business data, voice, and network management using C-COR's MPS (Metro Packet Switch) Platform.

--Broadcaster-to-cable headend interconnect for standard and high definition video using C-COR's DV6300 optical transport system and multi-port DVB-ASI/SMPTE 310 modules.

--Cable operator Regional Network Interconnect for analog video/audio, digital video/audio, and packet video, using C-COR's DV6000(TM) digital fiber optic transport system and DAP4 controller module with plug-in optical receiver.

--VOD (Video-on-Demand) transport from centralized video servers to edge QAM devices, using C-COR's CHP GigE Max and Edge Max5500 to provide Gigabit Ethernet transport and conversion to QAM RF.

About C-COR's Optical Packet Digital Video Delivery

The MPS platform is the next-generation packet-based transport technology for C-COR's popular DV6000 family of digital video products. With operational deployments worldwide by major telecommunications companies, CATV providers, and private video network operators, the DV6000 is the global first name in video transport. The MPS, acquired by C-COR through its recent purchase of Lantern Communications, combines 10 Gigabit optical packet transport with advanced bandwidth and Quality of Service (QoS) management to enable an infrastructure on which thousands of deterministic and Ethernet-based services are supported simultaneously, including T1 telephony and Gigabit Ethernet for VOD streams and Internet access.

About C-COR's VOD Transport Solution with Edge QAM Processing

C-COR's Edge Max5500 provides edge QAM processing of up to 240 single program transport streams in a scaleable 1RU shelf. Cable operators can start with a 12 QAM channel unit and scale the configuration to 24 QAM channel while maintaining their initial investment. C-COR's CHP Max5000 Converged Headend Platform provides digital transport using the GigE Max Gigabit Ethernet module and enables forward path optical transport into the HFC network using field-proven direct modulated transmitters. The scalable GigE Max performs grooming and transport using an internal packet switch for processing of Gigabit Ethernet streams from video servers to remote Edge Max5500 devices. The GigE Max internal layer 3-packet switch grooms traffic at the video server end for efficient WAN (Wide Area Network) transport. At the edge QAM device end, the switch scales traffic providing the Edge Max5500 the exact amount of video streams without stranding bandwidth. In the event of a service interruption or maintenance time for the Edge Max5500, the GigE Max can re-direct traffic to an alternate unit, maximizing service availability.
