发明名称 Method for downloading a scrambled television signal and receiver therefor.
摘要 <p>A scrambled television signal is downloaded for recording on a video cassette recorder (VCR) (10) by receiving a scrambled signal via an antenna (2) and a tuner (4). A descrambler (6) determines whether or not the signal contains a predetermined data code and if the data code is present enables operation of the descrambler (6) as well as generating an "access granted logic signal" to enable operation of a microprocessor/logic control circuit (8). The microprocessor/logic control circuit generates control signals for the VCR (10) and these may be via an infra-red control unit (18). The control signals cause the VCR (10) to record the descrambled output of the descrambler (6).</p>
