Abstract: A display monitor (12) operates in a time-multiplexed fashion to display a plurality of viewer-selected video channels on a single display screen. A visual apparatus (22) worn by the viewers is synchronized to the operation of the display monitor for enabling each of the viewers to observe the display screen only at times when the viewer-selected video channel is being displayed.

Abstract: Apparatus and a method are disclosed for operating a data processing system that is coupled to a data communications network. The method includes a first step of storing a plurality of Bookmarks, individual ones of which refer to one of a plurality of data communications network sites, wherein each of the plurality of data network communications network sites provides a similar type of information. A second step designates one of the plurality of Bookmarks as a currently active Bookmark based on at least one criterion. In one embodiment the step of designating is executed in response to a user selecting a Multiplexed Bookmark that comprises the plurality of Bookmarks, while in another embodiment the step of designating is executed periodically. The at least one criterion can be, by example, a time of day, a location of the data processing system, or a bandwidth of a data communications link between the data processing system and the data communications network.
