Abstract

A method is described, comprising: forwarding a request for data to an Internet site on behalf of a portal device; receiving the data from the Internet site on behalf of the portal device; converting the requested data to a format which the portal device can interpret to produce converted data; and transmitting the converted data to the portal device.

Claims

1. A portal system comprising:

a portal device comprising a processor for processing native program code and an interpreter module for interpreting bytecodes and converting the bytecodes into the native program code for processing by the processor;

a portal server to forward a request for data to an Internet site on behalf of a said portal device;

receive said data from said Internet site on behalf of said portal device;

the portal server comprising

a content conversion module to convert said requested data to bytecodes which said interpreter module on said portal device can convert into native program code; and

discard portions of said requested data which said portal device is incapable of processing;

the portal server to transmit said bytecodes to said portal device;

wherein said interpreter module comprises a modular networking interface for communication over a wireless network according to a specified network protocol; and

wherein converting said requested data further comprises;

determining said portal device'"'"'s graphical capabilities; and

converting said requested data to a particular bytecode format based on said graphical capabilities, said interpreter module converting said particular bytecode format into video format directly processable by said processor.

2. The portal server as in claim 1 wherein said bytecodes are Java bytecodes.

3. The portal server as in claim 1 wherein said request for data is transmitted to said portal server by said portal device over a wireless link.

4. The portal server as in claim 3 wherein said request for data is transmitted using a cellular digital packet data (“

CDPD”

) standard.

5. The portal server as in claim 3 wherein said request for data is transmitted using a third generation (“

3G”

) wireless standard.

6. The portal server as in claim 1 further comprising:

a cache for storing bytecodes based on a caching policy.

7. The portal server as in claim 6 wherein said caching policy factors in how long said bytecodes have been stored in said cache.

8. The portal server as in claim 6 wherein said caching policy includes a determination as to whether said bytecodes are current.

9. The portal server as in claim 1 wherein converting said requested data further comprises:

determining said portal device'"'"'s audio capabilities; and

converting said requested data to a particular bytecode format based on said audio capabilities, said interpreter module converting said particular bytecode format into an audio format directly processable by said processor.

10. A computer implemented method comprising:

forwarding request for data to an Internet site on behalf of a portal device;

receiving said data from said Internet site on behalf of said portal device;

converting said requested data to bytecodes which an interpreter module on said portal device can convert into native program code which a processor on said portal device can process;

discarding portions of said requested data which said portal device is incapable of processing; and

transmitting said bytecodes to said portal device;

wherein said interpreter module comprises a modular networking interface for communicating over a wireless network according to a specified network protocol; and

wherein converting said requested data further comprises;

determining said portal device'"'"'s graphical capabilities;

said

converting said requested data to a particular bytecode format based on said graphical capabilities, said interpreter module converting said particular bytecode format into a video format directly processable by said processor.

11. The method as in claim 10 wherein said bytecodes are Java bytecodes.

12. The method as in claim 10 wherein said request for data is transmitted to said portal server by said portal device over a wireless link.

13. The method as in claim 12 wherein said request for data is transmitted using a cellular digital packet data (“

CDPD”

) standard.

14. The method as in claim 12 wherein said request for data is transmitted using a third generation (“

3G”

) wireless standard.

15. The method as in claim 10 further comprising:

storing bytecodes in a cache based on a caching policy.

16. The method as in claim 15 wherein said caching policy factors in how long said bytecodes have been stored in said cache.

17. The method as in claim 15 wherein said caching policy includes a determination as to whether said converted data are current.

18. The method as in claim 10 wherein converting said requested data further comprises:

determining said portal devise'"'"'s audio capabilities;

said

converting said requested data to a particular bytecode format based on said audio capabilities, said interpreter module converting said particular bytecode format into an audio format directly processable by said processor.

19. A portal system comprising:

a portal device comprising a processor for processing native program code and an interpreter module for interpreting bytecodes and converting the bytecodes into the native program code for processing by the processor;

a portal server to forward a request for data to an Internet site on behalf of said portal device;

receive said data from said Internet site on behalf of said portal device;

the portal server comprising

a content conversion module to convert said requested data to bytecodes which said interpreter module on said portal device can convert into native program code; and

discard portions of said requested data which said portal device is incapable of processing;

the portal server to transmit said bytecodes to said portal device;

wherein said interpreter module comprises a modular networking interface for communicating over a wireless network according to a specified network protocol; and

wherein converting said requested data further comprises;

determining said portal device'"'"'s audio capabilities; and

converting said requested data to a particular bytecode format based on said audio capabilities, said interpreter module converting said particular bytecode format into an audio format directly processable by said processor.
