Patent ID: 7430681

Claim:
A method of transmitting encoded computer display images from a first computer system to a second computer system, the second computer system having a display controller, the first computer system deriving timing information from the display controller, the display controller configured to transmit a sequence of image sections to a display device, the method comprising: establishing a display session between the first computer system and the second computer system over a nondeterministic computer network, during which image data is transmitted from the first computer system to the second computer system; and until the display session is terminated, repeating the acts of: the second computer system requesting at least one section of an encoded computer display image of a plurality of image sections from the first computer system at a predetermined time in advance of when the requested at least one section is to be transmitted by the display controller; the second computer system receiving the at least one section at a received time, the received time having a received time value; comparing the received time value of the at least one requested section from the first computer system to a display controller timing value; determining whether the received time value is outside of range of time values that are within an acceptable delivery time limit with respect to the display controller timing value; and adjusting the predetermined time if the received time value is outside of the range of time values.
