Abstract (en)
[origin: WO02058382A1] A set-top box (STB) in a subscriber unit of a combined digital television and communication system is described. The STB includes a controller and a quadrature amplitude modulation (QAM) based tuner operatively controlled by the controller to selectively enable shared use of the QAM based tuner between the following two functions: tuning to a digital television frequency; and providing a downstream cable-modem link. Related apparatus and methods are also described.
