The integrated solution is targeted at manufacturers' intent on gaining strategic advantage in the high-definition STB market.

"S3 has a wealth of experience both with OpenTV products and also with ST and Nagravision systems and their coLinkTV solution brings clear benefits in time-to-market for advanced, interactive, high definition STBs."

Referring to the announcement, Paul Kavanagh, Product Marketing Manager at S3, said, "This is a key activity for S3, demonstrating the rapid introduction of OpenTV Core 2.0 on new STMicroelectronics designs. We believe that our coLinkTV software has a major role to play in the rollout of high definition TV services around the world, and we look forward to continuing this collaboration."

Eric Chaubert, VP of Business Development at Nagravision, said, "Nagravision is pleased to collaborate with S3, OpenTV, and ST on this exciting project. The combination of the S3 coLinkTV solution integrating the Nagravision Conditional Access Kernel and OpenTV Core 2.0 really makes sense to many of our customers and will speed their deployments of new solutions based on ST’s latest designs."

"coLinkTV is the missing link between OpenTV and the driver software for our STB710x device and we believe that the S3 software will enable our customers to rapidly deploy new designs based on our STB710x series," added Christos Lagomichos, VP of Home Entertainment Group at STMicroelectronics.
