A method for determining a median value in a sliding window environment is provided. The method includes creating a merge tree defining leaf nodes associated with columns corresponding to a first position of a sliding window. A display controller and a computer readable medium having program instructions for determining a median value in a sliding window environment are also provided.

A videoconferencing system configured to utilize peer-to-peer videoconferencing software to provide a multi-participant conference environment for a plurality of participants is provided. The system includes a client component defining a conference client enabled to execute peer-to-peer videoconferencing software. The client component includes a client monitor configured to monitor both, whether the conference channel is active and events within a video window displayed by the conference client, wherein the events within the video window are communicated across a back-channel connection. The back-channel connection is established when the conference channel is active. The system includes a server component having a back-channel controller in communication with the client monitor through the back-channel connection. The server component provides a client configurable audio/video stream for each of a plurality of participants. A graphical user interface and methods for providing a multi-participant conferencing environment are provided.

A method for determining a k order statistic is provided. The method initiates with identifying at least two sorted sets. Then, a recurrence configured to eliminate elements of the at least two sorted sets is defined. Next, an index value associated with a k order statistic is reduced through the recurrence to obtain a base case. After obtaining the base case, a minimum value of remaining elements is selected from the at least two sorted sets. The minimum value corresponds to the k order statistic. A display controller having circuitry for determining a median value and a computer readable medium having program instructions for determining a k order statistic are also provided.

A multi-participant videoconference system incorporating a back-channel connection and a client video mixer is disclosed. The multi-participant videoconference system includes a client component and a server component. The server component provides a composite conference video signal to the client component. A region is defined in the composite conference video signal and the size and coordinates of the region are communicated to the client component by the server component over the back-channel. The client component captures local video and mixes local video into the composite conference video signal using the size and coordinates received from the server component for display.

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.
