Three of the nation's largest MSOs are introducing set-top boxes which will open the way for more IP-enabled services in the home.
Docsis Set-to Gateway (DSG) set-tops can act as residential gateways, VOIP terminals, and other IP-enabled devices, supporting such new convergence services as video email and caller ID on the TV screen. They also can be used for unicasting, or delivering a unique video stream to each home and even set-top.
Richard Rioboli, VP of product platform engineering for Comcast, said the MSO's embrace of DSG technology is part of the company's drive to standardize different configurations. Without such standardization it would be tough for the company to introduce new cable services and applications quickly on a national basis.
Time Warner, Comcast, and Cox are beginning to introduce OpenCable Application Platform (OCAP)-equipped set-top boxes and TV sets in select markets. The OCAP middleware stack enables cable operators to offer the same interactive and on-demand services throughout the country. Plus, interactive application developers can create a single piece of software to run their applications on many different cable systems.
Comcast executives plan lab trials to start this winter as well as live OCAP deployments in several undisclosed markets before the end of the year. Meanwhile, Cox has begun testing several interactive TV services in Gainesville. Plans call for expanding the OCAP trial to other Cox cable systems later this year. In those new markets, Samsung intends to try out OCAP-based HD set-top boxes as well.
