The present disclosure includes a prescriptive engine system and a method of using the prescriptive engine system. The method includes receiving information on actions and receiving information on participants, the information on the participants including first suitability information of at least one participant for at least one of the actions, generating, based on the first suitability information, second suitability information for a set of participants for at least one action, allocating, based on the second suitability information, the at least one action to the set of participants, deploying the at least one action to the set of participants, receiving, after the at least one action has been performed, results of the at least one action for each participant in the set of participants, and updating, based on the received results, the first suitability information of each participant in the set of participants for the at least one action.

In accordance with the teachings of the present invention, a system and method for bit stream compatible local link encryption are provided. In particular embodiments of the present invention, the method includes generating a random number stream using an active line count of a frame of video as an input to a first random number generator in a playback server; encrypting data at the playback server based upon a first deterministic mapping between the first random number stream and the data, wherein the first deterministic mapping prevents the generation of prohibited codes; transporting the encrypted data from the playback server to a digital video projector; generating a second random number stream using the active line count of the frame of video as an input to a second random number generator in the digital video projector; and decrypting the encrypted data at the digital video projector based upon a second deterministic mapping between the second random number stream and the encrypted data.

In accordance with the teachings of the present invention, a system and method for transporting an ancillary data packet in the active area of a video stream are provided. In particular embodiments of the present invention, the method includes coupling a playback server and a digital video projector with a DVI link; placing an ancillary data packet of link encryption metadata in a false line of video in an active area of a frame of video at the playback server, a remainder of the active area comprising true lines of video; transmitting the ancillary data packet from the playback server to a digital video projector through the DVI link; extracting the ancillary data packet from the frame of video at the digital video projector; and displaying the remainder of the active area of the frame of video at the digital video projector.

A method and apparatus for a signal encryption device constructed to perform synchronous stream cipher encryption for a sequence of input words with restricted codes. The encryption device includes a keystream generator for producing a sequence of pseudorandom words from a key, and an adder that is used to sum the output of the keystream generator and the input words. A lookup table of size substantially twice the number of possible input words provides encrypted codes excluding restricted codes from the summed signal. A signal encryption and decryption system is constructed by including a second keystream generator for producing a second sequence of pseudorandom words from the key, and a second adder to produce a second summed signal from the output of the second keystream generator and the encrypted codes. A corresponding lookup table provides decrypted codes excluding restricted codes from the second summed signal.

Method and apparatus for synchronous stream cipher encryption with reserved codes

A method of producing an image. Image data word comprising image data bits for a portion of the image is received at a first frame rate. At least two threshold data values are selected. A first portion of the image data word is compared with the threshold data values. A second portion of said image data word is displayed at a frame rate at least two times said first frame rate. Image data based on the comparison between the first portion of the image data word and the threshold data values is displayed at a frame rate at least two times the first frame rate.

Parallel dithering contour mitigation

A method and system for displaying fractional bit data in order to increase the bit depth of a PWM display without requiring the use of an excessive number of bit planes. One embodiment of the present invention combines the outputs of two random number generators ( ) with the outputs of a row counter ( ) and column counter ( ) to yield row and column indexes into two 32&times;32 cell blue noise masks. The row and column indexes select a blue noise mask threshold for a given pixel. The threshold from the first blue noise mask ( ) is applied to a comparator ( ) where it is compared to the fractional bit portion of the pixel data. A first blue noise bit, BN( ), is generated based on this comparison. Typically, BN( ) is a &ldquo;1&rdquo; when the fractional portion of the pixel data exceeds the threshold value from the mask. The same threshold data is also processed by inverter ( ) to produce the threshold that would be shored in an inverted form of Mask A. Inverter ( ) prevents the circuitry from having to store four separate blue noise masks. The output of the inverter ( ) is also compared to the fractional pixel data to produce a second blue noise bit, BN( ). In the same manner, the second blue noise mask ( ) is used to generate two additional blue noise bits. The four blue noise bits are then used alternately in the quad-frame display of FIG. with the integer portion of the pixel data.
