Portable high speed internet access device priority protocol
First Claim
1. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that the priority of sending information is dependent upon the current position of a remote device display, in relation to the rendered virtual display.

Abstract
The present invention aims to provide a system that allows multiple users operating a PDA (Personal Digital Assistant) to access the Internet or the World Wide Web (WWW), and to be able to view and interact with these images remotely on a display screen. The invention provides a client and server system to facilitate multiple PDA users simultaneously on a single server, which has multiple virtual machines contained within, with each virtual machine containing a web browser. The invention relates to the priority in which packets or blocks of information are transferred to and displayed on the screen of the PDA device. The invention also relates to the interlacing of blocks and the construction of such blocks displayed on the PDA screen. The invention further relates to the sending, receiving, and acknowledgement of these blocks between the PDA and server.

- 1. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that the priority of sending information is dependent upon the current position of a remote device display, in relation to the rendered virtual display.

3. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that the priority of sending the information depends on the intent of the user to move a device display in a particular direction with respect to the virtual display.
- 6. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that a first priority is to download information of primarily text portions of a lower bit depth and a picture portion at a higher bit depth.

8. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that only limited information is downloaded to the device before acknowledgement is sent of previous information.
-
9. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that no information is sent to the device until the browser has fully rendered the information in its memory.
-
10. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that priority of download depends on history of user visiting information in the past.
-
11. A host computer which receives information from an outside source, contains a browser with a window which renders this information onto a virtual display in its memory, whereby a software program reduces the color depth of the rendered virtual display, compresses this reduced virtual display and sends it to a remote device capable of receiving, decompressing, storing into memory and displaying it to a user such that some information comprising the remote device display area is first sent to the remote device for display, whereby more information is sent at a later time to display all information within the remote device display area.
