摘要:
One embodiment of the invention relates to an apparatus comprising an input, a descrambler unit and a re-scrambler unit. The input is adapted to receive scrambled content. The descrambler unit is coupled to the input. The descrambler unit descrambles the scrambled content in order to recover unscrambled content and concurrently routes both the unscrambled content over a first communication link for display on a display device and the unscrambled content over a second communication link. The re-scrambler unit is coupled to the second communication link. The re-scrambler unit is adapted to scramble the unscrambled content to produce re-scrambled content for transmission.
