New Product Introduction -- Astria(R) VSP -- The company is debuting the Astria(R) Video Services Processor (VSP), its new carrier class IP-to-RF video edge modulation platform. The Astria VSP provides unparalleled scalability in a single chassis, enabling telcos and MSOs to utilize IP for video transport and then converting the IP video streams to RF for last-mile delivery of analog and digital TV over FTTP/FTTH and coax networks (see separate press release issued today for more detail).

Real-time MPEG-4 AVC Encoding -- Tut Systems will demonstrate how its new MPEG-4 AVC encoder for its Astria(R) Content Processor (CP) family of products reduces required video compression rates up to 50% while simultaneously improving overall video quality.

Forward Error Correction & MPEG-2 4:2:2 Video -- Tut Systems will demonstrate Forward Error Correction (FEC) applied to its MPEG-2 4:2:2 encoding/decoding solution; the demo provides a side-by-side comparison of impaired and corrected video streams to demonstrate the inherent need for and benefits of FEC when delivering digital video over IP networks.
