Latest Patents

One of Auld's latest patents is for an "Enhanced security for a cable system." This invention incorporates video inversion with mode signals included in the vertical blanking interval of a scrambled television signal. It allows for the identification of the proper mode for a video inverting/non-inverting amplifier at a subscriber station. An encoded mode control signal is sent periodically with the scrambled television signal to select the operative mode signals. The receiver applies these mode signals to the video amplifier, while a microprocessor decodes the mode control signal to ensure proper operation. A new decoding algorithm can be periodically downloaded to subscriber stations to enable changes in the encoded mode control signal.

Another significant patent is the "Dual in-band/out-of-band CATV system." This invention features a dual receiver that includes a coupler for input signals to a tuner and decoder. It allows for the demodulation and recovery of in-band data, as well as out-of-band data through an FSK receiver. The outputs from both the decoder and FSK receiver are coupled to a data switch, which controls the operation of the tuner/decoder microprocessor. This system defaults to in-band data whenever a channel change occurs, ensuring seamless operation.
