Claims
- 1-32 (Canceled).
- 33. A method of copy protecting signals flowing from a descrambler module to a receiver via a link, said copy protecting method in the receiver comprising the steps of:
(a) receiving a digital signal in the receiver, said digital signal including a scrambled signal; (b) generating a copy protection data signal by utilizing a scheme which uses random number generation; (c) transmitting said digital signal from the receiver to the descrambler module via the link; (d) receiving a copy protected signal, which has been descrambled and copy protected using said copy protection data signal, from said descrambler module; and (e) reconverting said copy protected signal to the descrambled signal in the receiver using said copy protection data signal.
- 34. The method of claim 33, further comprising the step of transmitting said copy protection data signal from the receiver to the descrambler module via the link.
- 35. The method of claim 33, wherein said digital signal in step (a) is encoded and scrambled.
- 36. The method of claim 33, wherein the descrambler module comprises a PCMIA card.
- 37. The method of claim 33, wherein the link comprises one or more communication mediums configured for carrying digital signals.
- 38. The method of claim 33, wherein the receiver and the descrambler module utilize IS679 compatible interfaces for communication via the link.
- 39. The method of claim 33, further comprising the step of decoding the descrambled signal in the receiver after the step of reconverting.
- 40. A method of copy protecting signals flowing from a descrambler module to a receiver via a link, said copy protecting method in the receiver comprising the steps of:
(a) receiving a digital signal in the receiver, said digital signal including a scrambled signal; (b) transmitting said digital signal from the receiver to the descrambler module via the link; (c) receiving a copy protected signal, which has been descrambled and copy protected using said copy protection data signal, from said descrambler module; and (d) reconverting said copy protected signal to the descrambled signal in the receiver using said copy protection data signal.
- 41. The method of claim 40, further comprising the step of generating a copy protection data signal by utilizing a scheme which uses a random number generation in the receiver.
- 42. The method of claim 41, further comprising the step of transmitting said copy protection data signal from the receiver to the descrambler module via the link.
- 43. The method of claim 41, further comprising the step of descrambling said digital signal and converting said descrambled signal into the copy protected signal using the copy protection data signal.
- 44. The method of claim 40, wherein said digital signal in step (a) is encoded and scrambled.
- 45. The method of claim 40, wherein the descrambler module comprises a PCMIA card.
- 46. The method of claim 40, wherein the link comprises one or more communication mediums configured for carrying digital signals.
- 47. The method of claim 40, wherein the receiver and descrambler module utilize IS679 compatible interfaces from communication via the link.
- 48. The method of claim 40, further comprising the step of decoding the descrambled signal in the receiver after the step of reconverting.
