Abstract
A method of transmitting encoded computer display images between computers over a nondeterministic network is disclosed. During a display session in which images are transmitted from a host to a client, the client requests sections of encoded image updates at a predetermined time in advance of when the requested at least one section is to be transmitted by the display controller. When the requested section is received, a time value is compared to a display controller timing value and, if the difference between the compared times is outside of an acceptable range, the client adjusts a predetermined time at which time the client requests image sections from the host.
