Display system with nested information display
First Claim
1. An information display system comprising:
- connection means for establishing selective connection between the display system and a number of different information sources to obtain information therefrom,a display device for the display of information obtained from said information sources,central processor means connected to said display device and said connection means for determining from which information source information is to be obtained and displayed,interface apparatus connected to said central processor means and operating under user control to generate and apply to said central processor means signals representing any selected point on a display area of the display device, andlogic control means included in said central processor means causing the display on the display device of frames of available options which pertain to said information sources, said logic control means comprising;
(a) means for producing, on initialization, a first display frame defining at least two discrete areas which are identified as pertaining to different facility options assigned to said areas, said first display frame further defining within at least one of said discrete areas at least one discrete sub-area which is identified as pertaining to one or more further facility options assigned to said sub-area,(b) means for producing a second display frame in response to the selection by said interface apparatus of a point which is within one of said areas but not within a sub-area of that area, said second display frame defining at least sub-areas which are identified as pertaining to different facility options assigned to said sub-areas, and(c) means for producing a third display frame in response to the selection by said interface apparatus of a point which is within a sub-area, said third display frame defining at least two discrete sub-sub-areas within said sub-area which are identified as pertaining to different facility options assigned to said sub-sub-areas, and if said selected area or sub-area pertains to a single facility option, providing a visual indication of the selection of that facility option,the logic control means then causing said central processor means to operate said connection means to establish connection to the information source pertaining to the selected facility option.

Abstract
An information display system which can produce an information display (e.g. on a television monitor) from any one of a plurality of different information sources. The information sources are associated with different facilities such as teletext and viewdata. In order to obtain information from a particular information source, the associated facility option is selected from the available facility options by selecting from the television screen "nested" areas which pertain to one or more facility options. The selection can be effected using a touch-sensitive screen which overlies the television screen. The selection process may comprise the display of a number of successive display frames containing "nested" areas. The selection of an area in one frame produces a fresh display frame which redefines areas which are nested within the selected area.
