 (WO 01/28255) DIGITAL AND ANALOG TELEVISION SIGNAL DIGITIZATION AND PROCESSING DEVICE   (Site not responding. Last check: 2007-11-06)
(57) A digital and analog television signal digitization and processing device that performs the digitization and processing functions using a common reference frequency source that is used to generate multiple subclock signals, wherein the reference frequency source is independent of any synchronizing characteristic of the input signal.
For dual channel analog signal processing, the common frequency source is not locked to either channel/input signal.
Advantageously, the present invention allows all of the analog-to-digital converters and decoder circuitry/logic necessary for simultaneously digitizing and processing several analog and digital television signals to be integrated on a single integrated circuit as well as eliminating duplicate frequency generation circuits.

 Over the Air Reliance   (Site not responding. Last check: 2007-11-06)

Under this policy, there would be a gradual cessation of analog service, whereby (a) analog service would be shut off on a rolling geographic or market basis, coupled with (b) a decrease in analog power levels over time as digital broadcasters increase to full power.
