Scientific Atlanta bows switched digital video system
Scientific Atlanta  formerly took the wraps off a new switched digital video (SDV) system that's designed to help operators use their existing bandwidth more efficiently.
In this environment, operators can "switch" rather than broadcast niche programs that are on the end of the so-called "long tail" of content.
SA's platform enables operators to deploy an IP-based SDV system with gigabit quadrature amplitude modulation (GQAM) sharing support.
Designed for existing HFC networks, SA's SDV play can support legacy MPEG-based set-tops that cannot decode a DOCSIS or IP-based stream.
"With our IP-based solution, our customers can leverage the existing MPEG set-top infrastructure, take advantage of open, standard interfaces throughout the network elements, experience significant benefits through QAM sharing, and take an important step in the evolution toward an IP-based, next-generation architecture," said Michael Harney, president of SA's subscriber network systems.
