|  Dotcast’s
patented dNTSC® technology enables over-the-air distribution
of a high-speed digital broadband data stream. Using our technology,
digital data is inserted into the video spectrum of the analog signal
at the broadcast tower. Data is inserted in quadrature, and then
pre-distorted so it won’t impair the analog signal.
Dotcast receiving technology can be incorporated into the TV itself,
as well as into a set-top box, a sidecar, a PC or a home media server.
There, the digital data is extracted from the analog signal and
then loaded to a digital shelf which is trickle charged over time.
This allows large amounts of data to be stored and accessed on demand
by the viewer.
