US 9,313,273 B2 · Pull-configured distribution of imagery

Abstract

The present invention is a method, system and apparatus for flexible image sharing. In a system for flexibly distributing imagery in an image sharing session, an image cache can be disposed between an application sharing host and a plurality of application sharing viewers. Additionally, a multipoint communications server can be disposed between the image cache and the application sharing viewers and can be communicatively linked to the application sharing host. Importantly, a pull-based subscription model can be implemented in an image cache server hosting the image cache. In particular, the model can have a configuration for registering respective ones of the application sharing viewers to receive notifications of available updated imagery.

A system for flexibly distributing imagery over a computer communications network comprising:

an image sharing host comprising at least one computer with memory and at least one processor and communicatively coupled to a plurality of image sharing viewers over a computer communications network;
and,
an image cache disposed between the image sharing host and the plurality of image sharing viewers;
the system being configured to generate an image frame update of a screen for a shared application being commonly viewed by the image sharing viewers, to cache in the image cache the image frame update for the screen for the shared application, to notify registered ones of the image sharing viewers of said image frame update for the screen for the shared application, and to serve from the image cache said cached image frame update for the screen for the shared application to requesting ones of said image sharing viewers that had been notified.
