Abstract

A receiver of network data dynamically filters packets by packet type from a network device CPU based on usage information, such as time, day, location, and feature (e.g., “video” or “application”) selection.

Claims

1. A receiver of network data comprising:

a processor; and

a computer storage medium accessible to the processor and bearing instructions which when executed by the processor configure the processor for causing the receiver to filter network packets by packet type from a network device central processing unit (CPU) based on usage information, wherein responsive to a user selecting a “

video”

feature, the processor passes video packets but not binary application packets, wherein responsive to a user changing to an “

application”

feature selection, the processor passes binary application packets but not video packets.

2. The receiver of claim 1, wherein the usage information includes time.

3. The receiver of claim 1, wherein the usage information includes day of the week.

4. The receiver of claim 1, wherein the usage information includes location of the network device.

5. The receiver of claim 1, wherein the usage information includes feature selection.

6. The receiver of claim 1, wherein the receiver is implemented in the network device.

7. The receiver of claim 6, wherein the receiver wirelessly receives packets from the network and the network device is battery powered.

8. A method comprising:

receiving usage information pertaining to a network device;

based on the usage information, determining at least one desired packet type from a network; and

passing, from a packet receiver of the network device to a central processing unit (CPU) of the network device, only the packets determined to be desired, wherein responsive to a user selection of a “

video”

feature, the desired packet type includes video packets but not binary application packets, wherein responsive to a user selection of an “

application”

feature, the desired packet type includes binary application packets but not video packets.

9. The method of claim 8, wherein the usage information includes time of day.

10. The method of claim 8, wherein the usage information includes day of the week.

11. The method of claim 8, wherein the usage information includes location of the network device.

12. The method of claim 8, wherein the usage information includes user preference as indicated by input received from a user input device.

13. The method of claim 12, wherein the user preference is a “

video”

feature or an “

application”

feature of the network device.

15. The method of claim 8, wherein at least a first packet type is always passed to the CPU regardless of the usage information.

16. The method of claim 8, wherein the CPU executes the receiving and determining acts.

17. The method of claim 8, wherein the packet receiver executes the receiving and determining acts.

21. The method of claim 8, wherein the usage information is established by at least time of day, day, location of the network device.

14. (canceled)

18. Apparatus, comprising:

a data receiver;

a central processor unit (CPU) configured for receiving data from the data receiver, the CPU configured for having at least first and second operational states;

the data receiver configured for receiving packets having a first type and packets having a second type, the data receiver configured for sending packets having the first type to the CPU but not sending packets having the second type to the CPU when the CPU is in the first operational state, the data receiver configured for not sending packets having the first type to the CPU and sending packets having the second type to the CPU when the CPU is in the second operational state, the first type being video and the second type being binary application.

19. The apparatus of claim 18, wherein the operational state is based on time or day of the week or location of the apparatus.

20. The apparatus of claim 18, wherein the operational state is based on user preference.
