Latest Patents

One of Crowther's latest patents is a system for decoding transmitted scrambled signals. In a pay television system, a program signal is transmitted scrambled to prevent unauthorized reception. The scrambled signal is accompanied by authorization codes for each authorized subscriber, a subscription key, and a pay-per-view key. At the receiver, if the appropriate authorization code is received, the receiver functions in subscription mode, allowing the subscription key to descramble the program signal. If the appropriate authorization code is not received, the receiver switches to pay-per-view mode, enabling descrambling upon request. This innovative approach ensures that subscribers can access content even if there is a delay in receiving the authorization code.

Another significant patent involves authorizing coded signals in a transmission system. This system transmits authorization codes to allow subscribers to receive scrambled signals intelligibly. Instead of assigning each subscriber a unique authorization code, which would be time-consuming for national broadcasts, Crowther's arrangement includes a multi-bit binary code word unique to a group of subscribers. This code word is followed by a train of binary pulses, with each subscriber allocated a unique pulse position that either authorizes or inhibits their access to the scrambled signal.
