Abstract
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. For obtaining information from a particular information source the associated facility option is selected. This selection is made 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 can involve the display of a number of successive display frames containing "nested" areas, the selection of an area in one frame causing the display of a fresh display frame which re-defines areas which are nested within the selected area.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
304 words
An information display system having connection means for establishing selective connection to a number of different information sources to obtain information therefrom for display on the screen of a display device, a particular one of said information sources from which information is to be obtained at any time being determined by central processor means of the system as a result of the selection of one of a plurality of facility options which pertain respectively to said information sources and which are selectable from interface apparatus by which the central processor means can be accessed, in which information display system the interface apparatus is operable to generate signals to represent any selected point on the screen of the display device, and the central processor means includes logic control means for producing on the screen of the display device a display frame of available facility options, and which information display system is characterised in that in respect of the selection of a facility option the logic control means is operable to produce a first display frame defining at least two discrete areas which are identified as pertaining to different facility options, 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 facility options, the logic control means being further operable in response to the selection by said interface apparatus of a point which is in one of said areas but not within a sub-area of that area, or which is in a sub-area,to produce a second display frame which, if said area or sub-area pertains to a single option facility, gives a visual indication of the selection of that facility option, said logic control means then causing said connection means to establish connection to the appertaining information source.
Claim 2
Dependent Claim
304 words
An information display system having connection means for establishing selective connection to a number of different information sources to obtain information therefrom for display on the screen of a display device, a particular one of said information sources from which information is to be obtained at any time being determined by central processor means of the system as a result of the selection of one of a plurality of facility options which pertain respectively to said information sources and which are selectable from interface apparatus by which the central processor means can be accessed, in which information display system the interface apparatus is operable to generate signals to represent any selected point on the screen of the display device, and the central processor means includes logic control means for producing on the screen of the display device a display frame of available facility options, and which information display system is characterised in that in respect of the selection of a facility option the logic control means is operable to produce a first display frame defining at least two discrete areas which are identified as pertaining to different facility options, 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 facility options, the logic control means being further operable in response to the selection by said interface apparatus of a point which is in one of said areas but not within a sub-area of that area, or which is in a sub-area,to produce a second display frame which, if said area or sub-area pertains to a single option facility, gives a visual indication of the selection of that facility option, said logic control means then causing said connection means to establish connection to the appertaining information source.
Claim 3
Dependent Claim
68 words
An information display system as claimed in Claim 1, characterised in that the logic control means is still further operable, when in said first display frame a selected area containing sub-areas pertains to a plurality of facility options, to produce an alternative second display frame which re-defines each sub-area of the selected area as a respective area which is identified as pertaining to at least one facility option.
Claim 4
Dependent Claim
34 words
An information display system as claimed in Claim 2, characterised in that said alternative second display frame includes at least one further area which is identified as pertaining to at least one facility option.
Claim 5
Dependent Claim
46 words
An information display system as claimed in Claim 2 or Claim 3, characterised in that in said alternative second display frame at least one of said areas has defined within it at least one sub-area which is identified as pertaining to at least one facility option.
Claim 6
Dependent Claim
63 words
An information display system as claimed in Claim 1, characterised in that the logic control means is still further operable when in said first display frame a selected sub-area pertains to a group of facility options, to produce a different alternative second display frame which defines a plurality of areas which pertain to respective facility options or to respective pluralities of facility options.
Claim 7
Dependent Claim
56 words
An information display system as claimed in Claim 5, characterised in that in said different alternative second display frame at least one of the areas which pertains to a plurality of facility options has defined within it at least one sub-area which pertains to a single facility option, or to a plurality of related facility options.
Claim 8
Dependent Claim
40 words
An information display system as claimed in any preceding Claim; characterised in that said interface apparatus is of a type which can generate co-ordinate signals to represent the co-ordinates of any selected point on the screen of the display device.
Claim 9
Dependent Claim
34 words
An information display system as claimed in Claim 7, characterised in that said interface apparatus is a touch sensitive screen device having a touch sensitive screen which overlies the screen of the display device.
Claim 10
Dependent Claim
46 words
An information display system as claimed in any preceding Claim, characterised in that the logic control means is arranged to drive a video signal generator which provides video display signals such that the various areas and sub-areas are made distinctive in colour and/or shape and/or size.
Claim 11
Dependent Claim
39 words
An information display system as claimed in Claim 5, characterised in that said video display signals further define in respect of each active selection area the same characteristic feature which indicates that the area is an active selection area.
Claim 12
Dependent Claim
20 words
An information display system as claimed in any preceding Claim, characterised in that said display device is a television monitor.
