  • Coupling a filter graph space to a network driver space
    Patent number: 7433937
    Abstract: A communication path is established that allows for communication between a filter graph space and a network driver space in a system. The communication path allows bi-directional communication between a filter graph driver in the filter graph space and a network driver in the network driver space. Addresses of data can be passed from the network driver to the filter graph driver, which allows the filter graph driver to communicate with a filter graph manager as necessary to configure the filter graph space to obtain data from the requested address. The data obtained from the address is then passed from the filter graph driver to the network driver.

  • Method and system for confirming receipt of data opportunistically broadcast to client computer systems
    Patent number: 6002852
    Abstract: A method and system for opportunistically downloading data from a server computer system to client computer systems. The server computer system has a point-to-point transmission mechanism for receiving data from each client computer system and has a broadcast transmission mechanism for broadcasting data to the client computer systems. Each client computer system has a broadcast receiver for receiving data broadcast by the broadcast transmission mechanism when the client computer system is in a receiving state. In a preferred embodiment, the server computer system selects data to be downloaded from the server computer system to the client computer systems, and broadcasts the selected data using the broadcast transmission mechanism. Each client computer system that is in the receiving state receives the broadcasted data and sends a confirmation that the client computer system has received the broadcasted data to the server computer system using the point-to-point transmission mechanism.
