FRAMEWORK FOR SCREEN CONTENT SHARING SYSTEM WITH GENERALIZED SCREEN DESCRIPTIONS

摘要

A framework for a screen content sharing system with generalized screen descriptions is described. In one approach, a screen content update message is sent from a client device to a control plane where the client device wishes to share its screen content with a remote device. The remote device sends a message indicating an interest in receiving said update. The control plane subsequently retrieves a detailed description from the client device. Based on the computational context of the remote device, the detailed description may be trimmed to a more compatible format. In some embodiments, the detailed description is sent to the remote device and includes a screen description and a content description. The content of the shared screen is described and the content is subsequently retrieved from a service router. A shared screen content is assembled based on the screen description and the content retrieved from the service router.
