Simplified-file hyper text protocol
View Patent ↗A system is provided wherein relatively low-end computers, such as portable, battery-powered computers ordinarily incapable of sophisticated Internet browsing functions may be used to browse the Internet. The enhanced computing ability for such portables is provided by a unique Internet server adapted for transposing data files to alternative, low-information-density form, preferably comprising simplified or single files suitable for rapid processing and display by connected portable and other low-end computers In embodiments wherein batter-powered field units are used, battery life is exhibited far beyond what would be expected for a battery-powered computer with computing power for browsing the Internet directly. In some embodiments of the invention adapted files are saved and identified for future use in communicating with specific devices over Internet connections.
1. A digital picture system comprising:
a field unit comprising a digital camera;
a data server;
a proxy server; and
a client comprising a display, wherein
the data server is communicatively coupled to the field unit and to the proxy server;
the field unit comprises instructions for sending to the data server digital picture data associated with a digital picture taken by the digital camera;
the proxy server is communicatively coupled to the client;
the client comprises instructions for:
sending to the proxy server client display data indicative of a capability of the client display to display images; and
sending requests for digital picture data to the proxy server, and
the proxy server comprises instructions for:
storing the client display data;
receiving a request for digital picture data from the client;
obtaining the digital picture data from the data server in response to the request for digital picture data from the client;
transposing the digital picture data to reduce information density of the digital picture data in accordance with the stored client display data; and
transmitting the digital picture data with reduced information density to the client.
2. The system of claim 1 , wherein the field unit further comprises instructions for emailing the digital picture data to the data server.
3. The system of claim 1 , wherein the data server is communicatively coupled to the Internet.
4. The system of claim 1 , wherein the proxy server comprises instructions for transmitting the digital picture data to the client over the Internet.
5. The system of claim 1 , wherein the client display data comprises information selected from the group consisting of a display type, a display size, and a display resolution.
6. The system of claim 1 , wherein the client display data is associated with a client identifier, wherein the request for digital picture data comprises the client identifier, and wherein the instruction for transposing the digital picture data to reduce information density of the digital picture data in accordance with the stored client data comprises instructions for:
comparing the client identifier sent in the request for digital picture data to other client identifiers stored in the proxy server;
selecting client display data associated with the client identifier sent in the request; and
transposing the digital picture data using the selected client display data.
7. The system of claim 1 , wherein the proxy server further comprises instructions for simplifying a protocol associated with the digital picture data, and wherein the digital picture data with reduced information density transmitted from the proxy server is received by the client according to the simplified protocol.
8. The system of claim 1 , wherein the field unit further comprises a microphone and wherein the field unit comprises instructions for sending to the data server audio data received by the microphone.
9. The system of claim 8 , wherein the client further comprises instructions for:
sending to the proxy server client sound data indicative of a functional capability of the client to reproduce sound; and
sending a request for audio data to the proxy server; and
the proxy server further comprises instructions for:
storing the client sound data;
receiving a request for audio data from the client;
obtaining the audio data from the data server in response to the request for audio data from the client;
transposing the audio data to reduce information density of the audio data in accordance with the stored client sound data; and
transmitting the audio data with reduced information density to the client.
10. The system of claim 1 , wherein the client comprises a display and a processor, and wherein the processor comprises instructions for displaying the digital picture data in each of a plurality of user-selectable display modes.
11. The system of claim 1 , wherein the client further comprises instructions for displaying the digital picture data with reduced resolution such that the digital picture may be displayed entirely on the display.
12. The system of claim 1 , wherein the client further comprises instructions for processing the digital picture data to display a portion of the digital picture and for receiving user input to pan over the digital picture.
13. The system of claim 1 , wherein the client further comprises instructions for displaying a portion of the digital picture and for receiving user input to zoom into or out of the digital picture.
