Dotcast Inc. has unveiled a platform that boosts cable capacity by up to 400 Mbps for services such as video-on-demand and HDTV.

Delivering digital services over legacy analog cable lines, Dotcast's dNTSC encodes cable signals at the headend with a digital sub-carrier. At the customer home, a dNTSC-enabled cable box decodes the signal.

The company claims its technology can eliminate the need for costly, system-wide plant conversions to digital. The dNTSC platform can add system-wide, digital capabilities "at a fraction" of the cost of a full plant upgrade, the company claimed.

"Cable operators are sensitive to the consumer's hunger for all-digital systems that provide better picture quality, greater flexibility in viewing choices, and value-added services. But not every cable operator can afford to replace their existing systems with all-digital equipment, and even those who can need an effective transition strategy," said Dotcast President Douglas Evans, in a release.

The Walt Disney Corp.-run MovieBeam video-on-demand service uses Dotcast's datacasting technology.
