Abstract

There is provided a method of adjusting power consumption by a wireless device having a codec and a battery, where the codec has a plurality of states of operation and the battery has a plurality of power levels. The method comprises operating the wireless device at a first power level of the plurality of power levels and a first state of the plurality of states of operation, while in communication with a remote device; receiving a power level indication indicative of a second power level of the plurality of power levels; selecting a second state of the plurality of states of operation for the codec corresponding to the second power level of the plurality of power levels; and modifying the codec to operate at the second state of the plurality of states of operation.

Claims

1. A method of adjusting power consumption by a wireless device having a codec and a battery, said codec having a plurality of states of operation, said battery having a plurality of power levels, said method comprising:

operating said wireless device at a first power level of said plurality of power levels and a first state of said plurality of states of operation, while in communication with a remote device;

receiving a power level indication indicative of a second power level of said plurality of power levels;

selecting a second state of said plurality of states of operation for said codec corresponding to said second power level of said plurality of power levels; and

modifying said codec to operate at said second state of said plurality of states of operation.

2. The method of claim 1, wherein said second power level is lower than said first power level, and wherein said second state consumes less power than said first state.

3. The method of claim 2, wherein said codec operates at a lower average bit rate in said second state than in said first state.

4. The method of claim 2, wherein said codec has a plurality of modes, wherein in said first state, said codec operates in a first mode of plurality of modes, wherein in said second state, said codec operates in a second mode of plurality of modes, and wherein said second mode consumes less power than said first mode.

5. The method of claim 4, wherein said first mode is mode 0 of the VMR-WB and said second mode is mode 1 of said VMR-WB.

6. The method of claim 1, wherein said second power level is higher than said first power level, and wherein said second state consumes more power than said first state.

7. The method of claim 6, wherein said codec operates at a higher average bit rate in said second state than in said first state.

8. The method of claim 1, wherein said wireless device is a wireless telephone and said codec is a voice codec.

9. The method of claim 1, wherein said codec is a video codec.

10. The method of claim 9, wherein said selecting selects said second state of said plurality of states of operation for said codec corresponding to said second power level of said plurality of power levels and a size of video data.

11. The method of claim 1, wherein said codec is an image codec.

12. The method of claim 11, wherein said selecting selects said second state of said plurality of states of operation for said codec corresponding to said second power level of said plurality of power levels and a size of image data.

13. The method of claim 1 further comprising:

receiving said power level indication indicative of a third power level of said plurality of power levels;

selecting a third state of said plurality of states of operation for said codec corresponding to said third power level of said plurality of power levels; and

modifying said codec to operate at said third state of said plurality of states of operation.

14. A wireless device having adaptable power consumption, said wireless device comprising:

a battery having a plurality of power levels;

a codec having a plurality of states of operation; and

a power management module configured to monitor a power level of said battery and provide a power level indication to said codec based on said power level;

wherein said wireless device operates at a first power level of said plurality of power levels and a first state of said plurality of states of operation, while in communication with a remote device, and wherein said power management module provides said power level indication to said codec indicative of a second power level of said plurality of power levels, and wherein said codec selects a second state of said plurality of states of operation corresponding to said second power level of said plurality of power levels and modifies said codec to operate at said second state of said plurality of states of operation.

15. The wireless device of claim 14, wherein said second power level is lower than said first power level, and wherein said second state consumes less power than said first state.

16. The wireless device of claim 15, wherein said codec operates at a lower average bit rate in said second state than in said first state.

17. The wireless device of claim 15, wherein said codec has a plurality of modes, wherein in said first state, said codec operates in a first mode of plurality of modes, wherein in said second state, said codec operates in a second mode of plurality of modes, and wherein said second mode consumes less power than said first mode.

18. The wireless device of claim 17, wherein said first mode is mode 0 of the VMR-WB and said second mode is mode 1 of said VMR-WB.

19. The wireless device of claim 14, wherein said second power level is higher than said first power level, and wherein said second state consumes more power than said first state.

20. The wireless device of claim 19, wherein said codec operates at a higher average bit rate in said second state than in said first state.

21. The wireless device of claim 14, wherein said wireless device is a wireless telephone and said codec is a voice codec.

22. The wireless device of claim 14, wherein said codec is a video codec.

23. The wireless device of claim 22, wherein said codec selects said second state of said plurality of states of operation for said codec corresponding to said second power level of said plurality of power levels and a size of video data.

24. The wireless device of claim 14, wherein said codec is an image codec.

25. The wireless device of claim 24, wherein said codec selects said second state of said plurality of states of operation for said codec corresponding to said second power level of said plurality of power levels and a size of image data.

26. The wireless device of claim 14, wherein said power management module provides said power level indication to said codec indicative of a third power level of said plurality of power levels, and wherein said codec selects a third state of said plurality of states of operation corresponding to said third power level of said plurality of power levels and modifies said codec to operate at said third state of said plurality of states of operation.
