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).

The control signals cause the VCR (10) to record the descrambled output of the descrambler (6).</p> |
