Abstract

A system for establishing and effectuating a conference session includes a plurality of participants. In turn, the participants include a source capable of operating in a fixed network environment, and at least one destination capable of operating in a cellular network environment. The participants are capable of establishing a conference session where one of the participants is a host and the other participants are members. During the conference session, then, the host is capable of sharing content with the members by reformatting content rendered for a local display into a vectorized format, and reformatting at least one update to the rendered content into a vectorized format. The host can transfer the reformatted content and reformatted update(s) to the members, which are then capable of rendering the respective reformatted content and reformatted update(s) in a manner at least partially in synch with the host rendering of the respective content and update(s).
