Rendering graphical data for presenting for display at a remote computer

摘要

A method and system for controlling the rendering of graphical data for remote display, e.g. for delivery over a network (6) to a remote client (7). At a source computer (1), graphical data is rendered and transmitted to the remote computer (7). At the remote computer (7), the transmitted rendered graphical data is received and presented for display. The rate of presenting at the remote computer (7) of the graphical data is monitored and the rate at which graphical data are rendered at the source computer (1) is controlled in response to the monitored rate of presenting at the remote computer (7).

1. A method of controlling rendering of graphical data for remote display comprising:
at a source server computer:
rendering graphical data and transmitting the rendered graphical data to a remote client computer; at the remote client computer:
receiving the transmitted rendered graphical data;presenting the graphical data for display; andmonitoring the rate of presenting at the remote client computer of graphical data for display; at the source server computer:
receiving information on the rate of presenting for display at the remote client computer of the transmitted graphical data; andcontrolling the rate at which graphical data are rendered at the source server computer in response to the monitored rate of presenting for display at the remote client computer;monitoring the size of an image to be displayed at the remote client computer and, upon detecting a change in the image size, removing control of the rate at which graphical data are rendered at the source server computer to allow graphical data to be rendered at the source server computer at an uncontrolled rate;following removal of control of the rate at which graphical data are rendered at the source server computer, receiving at the source server computer information on the rate of presenting for display at the remote client computer of transmitted graphical data rendered at the source server computer at the uncontrolled rate; andsubsequently controlling the rate at which graphical data are rendered at the source server computer in response to the information received at the source server computer on the rate of presenting for display at the remote client computer the transmitted graphical data rendered at the source server computer at the uncontrolled rate.
