System for conveying and reproducing images for interactive applications

摘要

A system for conveying and reproducing images for use with interactive applications is described. The system includes one or more application modules producing images for a display, and a display server for deriving encoded representations of the images and forwarding them to one or more clients. The client includes one or more user input devices such as a touchpad or touchscreen, and forwards information derived from the data received from these devices to the display server. The information is also used locally to modify reconstructed images derived from the encoded image representations received from the display server. The modified reconstructed images are displayed on a video screen.

1. A system for conveying and reproducing images for use with interactive applications, said system comprising:
one or more interactive application modules producing images for display with selected characteristics responsive to user input; a display server operatively coupled to said one or more interactive application modules to encode initial encoded representations of said images with the selected characteristics and to modify the initial encoded representations responsive to the user input forwarded thereto to derive modified encoded representations; one or more clients, each including:
one or more user input devices operatively coupled to said display server to generate said user input and forward said user input to said display server;a virtual client display operatively coupled to said display server to receive and reconstruct the initial encoded representations of said images with the selected characteristics to form a first image reconstruction;a graphics processing unit operatively coupled to said display, said one or more user input devices and to said virtual client display to modify said first image reconstruction in response to said user input from said one or more user input devices to produce a second image reconstruction;wherein the virtual client display is operatively coupled to said display server to further receive and reconstruct the modified encoded representations of said images with the selected characteristics to form a modified image reconstruction; anda display operatively coupled to said virtual client display to sequentially display the first image reconstruction, the second image reconstruction, and the modified image reconstruction in this order.
