Abstract
Abstract The disclosure herein describes a system and a process for recording cartographic information on a videodisk; it comprises the steps of converting into digital raster format printed information displayed on geographic maps and charts; computer processing the converted information to create video frames; converting each raster frame into a video composite signal to form an analog frame; recording each analog frame onto an analog magnetic tape; and producing a videodisk containing the information obtain from the tape.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
70 words
A process for recording in high resolution form printed cartographic information contained on charts and maps onto videotape, the process comprising the steps of: scanning said printed cartographic information into digital raster format to form raster frames of said information; converting each of said raster frames into a video composite signal in the form of an analog frame; and, recording each of said analog frames onto an analog magnetic tape.
Claim 2
Dependent Claim
70 words
A process for recording in high resolution form printed cartographic information contained on charts and maps onto videotape, the process comprising the steps of: scanning said printed cartographic information into digital raster format to form raster frames of said information; converting each of said raster frames into a video composite signal in the form of an analog frame; and, recording each of said analog frames onto an analog magnetic tape.
Claim 3
Dependent Claim
88 words
A process for recording in high resolution form printed cartographic information contained on charts and maps onto a videodisk, the process comprising the steps of: scanning said printed cartographic information into digital raster format to form raster frames of said information; converting each of said raster frames into a video composite signal in the form of an analog frame; recording each of said analog frames onto an analog magnetic tape; and, thereafter creating a videodisk from information obtained from said analog frames recorded on said analog magnetic tape.
Claim 4
Dependent Claim
88 words
A process for recording in high resolution form printed cartographic information contained on charts and maps onto a videodisk, the process comprising the steps of: scanning said printed cartographic information into digital raster format to form raster frames of said information; converting each of said raster frames into a video composite signal in the form of an analog frame; recording each of said analog frames onto an analog magnetic tape; and, thereafter creating a videodisk from information obtained from said analog frames recorded on said analog magnetic tape.
Claim 5
Dependent Claim
144 words
A process for recording in high resolution form onto videotape printed cartographic information contained on charts and graphs, for later creation of a videodisk using the information recorded on said videotape, said process comprising the steps of: scanning said printed cartographic information into digital raster format; computer processing said scanned information to create video frames, said processing comprising cutting said scanned information into portions representing cartographic areas smaller than the total scanned cartographic area and creating raster frames corresponding to said smaller areas, digitally processing said raster frames to improve the video quality thereof, indexing and creating library files for each of said frames to indicate geographic coverage corresponding to each of said frames; converting each of said raster frames into a video composite signal in the form of an analog frame; and, recording each of said analog frames onto an analog magnetic tape.
Claim 6
Dependent Claim
144 words
A process for recording in high resolution form onto videotape printed cartographic information contained on charts and graphs, for later creation of a videodisk using the information recorded on said videotape, said process comprising the steps of: scanning said printed cartographic information into digital raster format; computer processing said scanned information to create video frames, said processing comprising cutting said scanned information into portions representing cartographic areas smaller than the total scanned cartographic area and creating raster frames corresponding to said smaller areas, digitally processing said raster frames to improve the video quality thereof, indexing and creating library files for each of said frames to indicate geographic coverage corresponding to each of said frames; converting each of said raster frames into a video composite signal in the form of an analog frame; and, recording each of said analog frames onto an analog magnetic tape.
Claim 7
Dependent Claim
160 words
A process for recording in high resolution form onto videotape printed cartographic information contained on charts and graphs, and later creation of a videodisk using the information recorded on said videotape, said process comprising the steps of: scanning said printed cartographic information into digital raster format; computer processing said scanned information to create video frames, said processing comprising cutting said scanned information into portions representing cartographic areas smaller than the total scanned cartographic area and creating raster frames corresponding to said smaller areas, digitally processing said raster frames to improve the video quality thereof, indexing and creating library files for each of said frames to indicate geographic coverage corresponding to each of said frames; converting each of said raster frames into a video composite signal in the form of an analog frame; recording each of said analog frames onto an analog magnetic tape; and, creating a videodisk from information obtained from said analog frames recorded on said analog magnetic tape.
Claim 8
Dependent Claim
160 words
A process for recording in high resolution form onto videotape printed cartographic information contained on charts and graphs, and later creation of a videodisk using the information recorded on said videotape, said process comprising the steps of: scanning said printed cartographic information into digital raster format; computer processing said scanned information to create video frames, said processing comprising cutting said scanned information into portions representing cartographic areas smaller than the total scanned cartographic area and creating raster frames corresponding to said smaller areas, digitally processing said raster frames to improve the video quality thereof, indexing and creating library files for each of said frames to indicate geographic coverage corresponding to each of said frames; converting each of said raster frames into a video composite signal in the form of an analog frame; recording each of said analog frames onto an analog magnetic tape; and, creating a videodisk from information obtained from said analog frames recorded on said analog magnetic tape.
Claim 9
Independent Claim
175 words
An apparatus for recording in high resolution form onto videotape printed cartographic information contained on charts and graphs, and later creation of a videodisk using the information recorded on said videotape, said apparatus comprising: digital scanner means for scanning said printed cartographic information into digital raster format; digital computer means for processing said scanned information to create video frames, said processing comprising cutting said scanned information into portions representing cartographic areas smaller than the total scanned cartographic area and creating raster frames corresponding to said smaller areas, digitally processing said raster frames to improve the video quality thereof, indexing and creating library files for each of said frames to indicate geographic coverage corresponding to each of said frames; converter means for converting each of said raster frames into a video composite signal in the form of an analog frame; video recorder means for recording each of said analog frames onto an analog magnetic tape; and, videodisk recorder means for creating a videodisk from information obtained from said analog frames recorded on said analog magnetic tape.
Claim 10
Independent Claim
