Abstract

Techniques are provided for cloning a computer desktop to a wireless display surface. A source computer and a display in communication with a destination computer establish a wireless connection. A user console session of the source computer has a virtual display driver that corresponds to the wireless display. An application of the console session instructs the virtual display driver to render graphics to a display surface. The source computer takes this graphical information that, when executed on a processor generate an image, text, sound or input-encodes it with a remote presentation protocol. Through encoding and decoding image data, text, sound, and input of the user console session transmitted to a wireless display with a remote presentation protocol, fidelity and interactivity are improved.

Description

technical field [0001] The present invention relates to improved techniques for displaying screen data on a wireless display and enabling a computer desktop experience. Background technique [0002] It has become common to share computer desktops and applications with remote clients using Remote Presentation Protocol (RPP) technologies such as Remote Desktop Protocol (RDP) and Independent Computing Architecture (ICA). These shared computing systems are typically established by instantiating user sessions for RPP sessions on the session's server. In cases where the server's screen is to be shared with the session's client, the RPP session obtains this information from a console session local to the server. During an RPP session, the client transmits keyboard presses and mouse clicks or selections to the server, which sends screen updates back to the client over a network connection (eg, the Internet) in the other direction. In this way, the user of the client has the experi...
