Abstract: A method for updating a subset of a frame of an image is provided. The frame of the image is subdivided into a plurality of tiles. The method initiates with providing a fixed-size queue having a stationary last packet at a bottom of the fixed size queue. Then, a plurality of packets is stored in a time sorted order above the last packet, the plurality of packets corresponding to a frame of an image. Next, an updated packet is received, the updated packet corresponds to a previously received packet of the plurality of packets. Then, the previously received packet is replaced with the updated packet while maintaining the time sorted order. Replacing the previously received packet includes: identifying the previously received packet adjusting any pointers pointing at the previously received packet to point at a packet below the previously received packet; and moving the previously received packet to a top of the fixed size queue. An apparatus and system for distributing packets through a multi point dispatcher between multiple clients is also provided.

Abstract: A technique that reduces the size of an existing JPEG file or set of DCT coefficients to satisfy a certain bit budget by setting to zero coefficients whose magnitude is below a certain threshold and which occur after a certain ordinal number in the zig-zag scan. The cutoff ordinal number is chosen using a clever savings calculation strategy. This strategy is implemented by filling appropriate savings values in an array of savings values, Savings[1], . . . , Savings[63]. The value Savings[n] is exactly the number of bits saved by reducing the thresholding cutoff ordinal number from n +1 to n. When a non-zero coefficient is set to zero, bits are saved because two runs of zeros (the one preceding it and the one following it) get combined into a single, longer run of zeros. The exact number of bits saved can be calculated by adding the bits needed to code the previous and next runs, and subtracting the bits needed to code the combined run. Some special conditions (runs longer than 16 and end-of-block conditions) need to be carefully factored into the computation.

Abstract: In an example embodiment, a calibration module in a projector platform establishes an initial configuration of settable exposure attributes for a digital camera. The calibration module projects a preview image onto a surface and captures the projection of the preview image with the digital camera and receives input from a user identifying regions of interest in the capture of the preview image. Next the calibration module projects an exposure image onto the surface. The calibration module then computes a final configuration of exposure attributes for the digital camera by iteratively: (a) capturing the projection of the exposure image with the digital camera; (b) measuring descriptive statistics relating to the color channels of pixels in the regions of interest in the capture of the exposure image; (c) evaluating the descriptive statistics with an evaluation function determined by a calibration process; and (d) establishing a revised configuration of exposure attributes.
