1. Field of the Invention
This invention falls into the field of using Global Positioning Satellites with a storage device wherein the position is utilized in combination with a cartographic or topographic representation, chart, atlas, etc. to either retrieve or store information.
2. Description of Prior Art
Existing portable Global Positioning Systems work by receiving a plurality of (three or more in general) artificial satellites and measuring the current position of the receiver by using the received radio signals. This signal may optionally be displayed on a display device embedded within the portable GPS. Moreover, map files selected on the basis of the signals received may also be displayed on the display embedded into the portable GPS device. Drawbacks with this system include the embedding of fragile display devices within the portable display, and having to incorporate both significant processing power within the portable device for the display and manipulation of map files and the geographic position of the portable device, and having to provide very large data storage capacity required by data-rich map and other geographic data files.
The present invention has been made in consideration of the above problems in the prior art, and has as its object the use of a Global Positioning Systems device within a remote control controlling a Digital Video Disc player and the placement of the display component in a separate display device connected to the same Digital Video Disc player. The data and some computer programs are stored on removable Digital Video Discs played in this same Digital Video Disc Player, and part of the processing load for selection, display, and manipulation of these map and other geographical data files is be done by processors in the same Digital Video Disc player. Selection of map and other geographical data is done using processing both from the reception of artificial satellite signals through which geographic position may be calculated, and using processing from user input on the remote control input devices such as keys. wherein the Global Positioning System device means a device capable of receiving and processing a plurality of radio signals from artificial satellites and processing these to calculate the geographical position of that same device. wherein the remote control means a portable (usually handheld) device that contains at least some keys for input as well optionally other devices for input such as dials. This same remote control then processes and transmits this input to a separate electronic device that is designed to receive the signals and carry out the requested electronic tasks. wherein a input device on a remote control is an electronic mechanism producing a signal that elicits a predefined reaction in the electronic device which it controls via the use of predefined key codes, usually infra-red in substance. wherein the Digital Video Disc player refers to an electronic machine capable of reading and processing the content of digital video discs for further tasks such as video and audio output according to that signal. wherein processing a signal refers to reception of that signal and digital or analog processing carried out by an electronic microprocessor to transform that signal into a new signal. wherein a map refers to a cartographic display of geographical data. wherein a geographical file refers to a data file containing data with at least some geographical positional information, but not necessarily with a cartographic display component. wherein artificial satellites refer to devices placed in the atmosphere by humans to emit signals of use on the surface of the earth. wherein selection means the electronics choice of files as guided by a microprocessor processing a signal. wherein display means video output to a device recognizable to the human eye wherein manipulation means use of the displayed map files, other geographic data files, and the signal from the Geographic Positioning System device to carry some electronic task requested by the user of the remote control.
