Abstract
Abstract A display system that uses a digital storage and processor having stored therein a plurality of sources of binary coded information representative of a plurality of display messages and patterns. A graphic generator converts coded information into analog stroke or painted display information. This stroke information and/or asynchronous display information from other sources is converted into television raster information which is then cyclically stored on a magnetic disk, together with displays from other synchronous noncoded and coded sources as well as live television. A plurality of remote stations can select any display information which is converted as necessary to raster video information. These frames may be recorded on one or more tracks of the magnetic disk. This information is then applied to the television monitor at the station. The operator at the station can then control the processing of the binary coded information and request other display material while viewing the monitor and in addition, can correlate portions of images on the CRT display with the originating digitally controlled stroke information. Furthermore, raster information of several selected tracks as well as synchronized video from other sources can be compared and/or mixed.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
161 words
Display system comprising: digital processing means including memory means having binary coded information representative of a visual display; converTer means operative to convert said coded information into non-coded television raster information that can be applied to a television display device for producing a visual display thereon; cyclic storage means connected to said converter means for cyclically storing said noncoded television raster information, wherein said converter means includes generator means for converting said coding information to non-coded display information, and scan converter means synchronizing said noncoded display information with said cyclic storage means; television display means; transducer means for manually identifying by XY coordinate signals a portion on said display and means comparing the signals of said generator means with the XY coordinate signals of said transducer means; and connecting means for selectively connecting said storage means and said display means to regenerate said non-coded television raster information and effect a continuous application thereof to the visual display on said display means.
Claim 2
Dependent Claim
161 words
Display system comprising: digital processing means including memory means having binary coded information representative of a visual display; converTer means operative to convert said coded information into non-coded television raster information that can be applied to a television display device for producing a visual display thereon; cyclic storage means connected to said converter means for cyclically storing said noncoded television raster information, wherein said converter means includes generator means for converting said coding information to non-coded display information, and scan converter means synchronizing said noncoded display information with said cyclic storage means; television display means; transducer means for manually identifying by XY coordinate signals a portion on said display and means comparing the signals of said generator means with the XY coordinate signals of said transducer means; and connecting means for selectively connecting said storage means and said display means to regenerate said non-coded television raster information and effect a continuous application thereof to the visual display on said display means.
Claim 3
Dependent Claim
31 words
Display system as set forth in claim 1 wherein said portion of said display is a rectangle determined by a pointer and preselected coded boundary signals in said digital processing means.
Claim 4
Dependent Claim
54 words
Display apparatus as set forth in claim 1 wherein said memory means includes a plurality of discrete binary information representative of a plurality of visual displays, wherein said cyclic storage means stores and cyclically regenerates a plurality of noncoded information, and means comparing the raster of one display with the raster of another display.
Claim 5
Dependent Claim
168 words
A display system for digital and analog information, said system comprising a digital processor having a plurality of storage locations therein, each of said storage locations having binary coded information representative of a discrete image; a graphic generator coupled to said digital processor for transducing the binary coded information into X, Y, Z signals capable of deflecting an electron beam; scan converter means coupled to said graphic generator for converting the X, Y, Z signals into television type raster information of an analog or digital nature; track selector means connected to the output of said scan converter means; magnetic storage means connected to the output of said track selector means, said magnetic storage means having a plurality of endless tracks formed thereon for storing and cyclically regenerating raster information received from said scan converter means; a distribution network connected to an output of said magnetic storage means; and a plurality of television monitors coupled to said distribution network for displaying the discrete image stored in said digital processor.
Claim 6
Dependent Claim
168 words
