Abstract
A host-client protocol facilitates delivery of screen images from a host to a remote access client when the host content is continuous or large (such as high definition (HD) content). To facilitate this operation, the protocol implements several functions and operations that provide the desired result of an HD stream viewable on the remote access client. These functions and operations include one or more of: frame rate adjustment, rate control, dynamic adjustment to the stream based on client-provided screen resolution or changes, eliminating portions of the host screen that are not in view on the remote access client, implementing client-initiated zoom/pan operations on the host instead of the client, performing zoom/pan operations, dynamic control over screen updates, and (where multiple clients are receiving the stream) delivering streams to different clients at different frame rates.
