  • Patent number: 4604650
    Abstract: The invention comprises a system for scrambling, transmitting and descrambling the video portion of a TV signal. In the preferred embodiment two serial memories (charge coupled devices) are utilized to store data representing selected portions of the video to be scrambled. The charge coupled devices are selectively clocked to interchange portions of video, with the point at which the interchange occurs determined by a code pattern generator and changing in a predetermined manner. The point of interchange is updated or changed as determined by a code pattern generator and changing every three lines of the TV signal. Descrambling is accomplished by an identical hardware arrangement with the exception that the code pattern generator at the descrambler is synchronized with the code pattern generator in the scrambler. Synchronizing information can be transmitted to the descrambler in any convenient fashion including inserting the data in an unused video line of the vertical retrace interval.

  • Patent number: 4547802
    Abstract: Apparatus for scrambling and descrambling the video portion of TV signals is disclosed. The video portion of the TV signal is stored in a serial memory such as a charge coupled device. Scrambling is accomplished by shifting the end portion of the lines of video to the beginning by recirculating the data stored in the charge coupled devices for a portion of a line of the video signal. Two charge coupled devices are provided so that when the data stored in one device is being recirculated for scrambling the subsequent line can be stored in a second device. Descrambling is an inverse operation and is accomplished in essentially identical hardware.

  • Patent number: 4521896
    Abstract: A dual transport channel charge coupled device for coherently processing two analog signals in a bandwidth compression mode of operation, especially for use in a high resolution coherent radar system, is disclosed. An input charge injection stage is included for each transport channel. The input stages are dependently operative to simultaneously inject charge quantities correspondingly representative of concurrent samplings of the two analog signals being processed into their corresponding associated transport channels. Each transport channel comprises N multi-phase controlled stages in an in-line arrangement with the stages of one transport channel respectively corresponding to the stages of the other, the stages being operative to transport the simultaneously injected charge quantities concurrently along their corresponding channels.

  • Patent number: 4488163
    Abstract: An array of photodetectors is described incorporating a PNP vertical structure in a monosilicon substrate with individual photodetectors optically and electrically isolated from one another by open or oxide filled grooves. Both PN junctions of the PNP structure or originally reverse biased with one junction acting as the photodetector may operate in the forward biased photovoltaic mode with high radiant energy intensity. The minority carriers injected into the N region are absorbed by the other PN junction providing base-collector transistor action to prevent blooming.
