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 number of cameras capture a scene and send corresponding video sub-streams to an acquisition PC. Each sub-stream is made up of a plurality of sub-frames. The acquisition PC sends the sub-streams over a network to a playback PC. The playback PC stores each sub-frame in a queue corresponding to an associated sub-stream. For each sub-stream the playback PC calculates a sub-stream average period to produce a plurality of sub-stream average periods. It then calculates a composite average period by averaging the plurality of sub-stream average periods, and calculates a playback frame rate as a reciprocal of the composite average period. The playback PC then reads the sub-frames from their corresponding queue in synchronism with the calculated playback frame rate to display the plurality of sub-streams.

Abstract translation: 许多摄像机拍摄场景并将相应的视频子流发送到采集PC。 每个子流由多个子帧组成。 采集PC通过网络将子流发送到重放PC。 播放PC将每个子帧存储在与相关联的子流对应的队列中。 对于每个子流，重放PC计算子流平均周期以产生多个子流平均周期。 然后，通过对多个子流平均周期进行平均来计算复合平均周期，并且将重放帧速率计算为复合平均周期的倒数。 然后，播放PC与所计算的播放帧速率同步地从其对应的队列中读出子帧，以显示多个子流。

Abstract: A best blending function from among a plurality of blending functions is determined. Each of the plurality of blending functions smoothes an overlap region of at least two projected images. The overlap image is captured and a processing unit analyzes the stored overlap image for color value linearity to calculate a first smoothness result. The processing unit analyzes the projection of the first or second image for color value uniformity to calculate a second smoothness result. These smoothness results for one blending function are paired and compared to smoothness result pairs corresponding to other blending functions to determine a best blending function from among those being analyzed.

Abstract: The display of a Windows Desktop is modified using one or more processors (e.g. CPUs and/or GPUs) that re-direct drawing of the Desktop to mirrored swap chain buffers; modify the contents of the a front buffer of the mirrored swap chain buffers; and draw the Desktop using the modified contents of the front buffer of the mirrored swap chain buffers. To modify the displayed Desktop, Windows needs to draw into these mirrored swap chains instead of its own. To accomplish this, all Direct3D functions that use a swap chain are hooked so that they return the mirrored swap chain, and any function that uses the contents of the swap chain are hooked. Basically any function that takes a Direct3D surface or texture is hooked and the respective item from the mirrored swap chains is returned if it is in the mirrored swap chain data structures.
