Abstract

A system and method to manage processes of a mobile device based on available power resources is disclosed. In a particular embodiment, an apparatus is disclosed that includes an interface configured to receive a user selection of a scheduled program to be received at a mobile device. The apparatus also includes a battery threshold calculator configured to determine a battery charge threshold based on at least one of a duration of the scheduled program and a processing complexity of the scheduled program. The apparatus includes an alert generator configured to generate a battery alert notification prior to receiving the scheduled program in response to a determination that a battery charge of the mobile device at a starting time of the scheduled program does not satisfy the battery charge threshold.

Claims

1. An apparatus comprising:

an interface configured to receive a user selection of a scheduled program to be received at a mobile device;

a battery threshold calculator configured to determine a battery charge threshold based on at least one of a duration of the scheduled program and a processing complexity of the scheduled program; and

an alert generator configured to generate a battery alert notification prior to receiving the scheduled program in response to a determination that a battery charge of the mobile device at a starting time of the scheduled program does not satisfy the battery charge threshold.

2. The apparatus of claim 1, wherein the interface is further configured to present an electronic program guide that lists one or more programs and wherein the electronic program guide provides an indication of at least one of the duration of the one or more programs and the processing complexity of the one or more programs.

3. The apparatus of claim 1, wherein the processing complexity includes at least one of:

a resolution type including at least one of standard definition or high definition;

a bit rate;

a frame rate; and

a spatial resolution complexity.

4. The apparatus of claim 1, wherein when the scheduled program is to be received at a present time, the battery threshold calculator is configured to determine the battery charge threshold based on a remaining duration of the scheduled program.

5. The apparatus of claim 4, wherein when the alert generator determines that the battery charge at the present time does not satisfy the battery charge threshold, the alert generator immediately generates the battery alert notification.

6. The apparatus of claim 1, wherein when the scheduled program is to be received at a future time, the battery charge at the starting time of the scheduled program is estimated based on a measured battery charge at a present time and an estimated amount of battery drain between the present time and the starting time of the scheduled program.

7. The apparatus of claim 6, wherein the alert generator is configured to determine at one more times in advance of the future time whether the estimated battery charge satisfies the battery charge threshold.

8. The apparatus of claim 1, wherein the alert generator is further configured to preemptively cancel receipt of the scheduled program prior to the receipt of the scheduled program when the estimated battery charge does not satisfy the battery charge threshold.

9. The apparatus of claim 1, wherein the alert generator is further configured to detect when an external power source is connected and to receive the scheduled program when the external power source is connected.

10. The apparatus of claim 1, further comprising a device selected from the group consisting of a portable television, a portable media player, a communications device, and a computer, into which the interface, the battery threshold calculator, and the alert generator are integrated.

11. A method of scheduling receipt of content at a mobile device, the method comprising:

receiving a user selection of a scheduled program to be received at the mobile device;

determining a battery charge threshold based on at least one of a duration of the scheduled program and a processing complexity of the scheduled program;

determining a battery charge of the mobile device at a starting time of the scheduled program; and

generating a battery alert notification prior to receiving the scheduled program in response to determining that the battery charge of the mobile device does not satisfy the battery charge threshold.

12. The method of claim 11, further comprising presenting an electronic program guide that lists one or more programs, wherein the electronic program guide provides an indication of at least one of the duration of the one or more programs and the processing complexity of the one or more programs, and wherein the user selection is received via the electronic programming guide.

13. The method of claim 11, wherein the processing complexity includes at least one of:

a resolution type including at least one of standard definition or high definition;

a bit rate;

a frame rate; and

a spatial resolution complexity.

14. The method of claim 11, wherein when the scheduled program is to be received at a future time, the battery charge at the starting time of the scheduled program is estimated based on a measured battery charge at a present time and an estimated battery drain between the present time and the starting time of the scheduled program.

15. The method of claim 11, further comprising determining at one or more times between receiving the user selection of the scheduled program and the starting time of the scheduled program whether the battery charge is predicted to satisfy the battery charge threshold at the starting time of the scheduled program.

16. The method of claim 15, further comprising preemptively canceling receipt of the scheduled program prior to receiving the scheduled program when an estimated battery charge or a measured battery charge does not satisfy the threshold battery charge.

17. The method of claim 11, further comprising stopping generation of the battery alert notification in response to detected connection of an external power source.

18. An apparatus for scheduling receipt of content at a mobile device, the apparatus comprising:

means for receiving a user selection of a scheduled program to be received at the mobile device;

means for determining a battery charge threshold based on at least one of a duration of the scheduled program and a processing complexity of the scheduled program;

means for determining a battery charge of the mobile device at a starting time of the scheduled program; and

means for generating a battery alert notification prior to receiving the scheduled program in response to determining that the battery charge of the mobile device does not satisfy the battery charge threshold.

19. The apparatus of claim 18, further comprising means for presenting an electronic program guide that lists one or more programs, wherein the electronic program guide provides an indication of at least one of the duration of the one or more programs and the processing complexity of the one or more programs, and wherein means for receiving the user selection receives the user selection via the electronic programming guide.

20. The apparatus of claim 18, wherein the scheduled program is to be received at a future time, the battery charge is estimated based on a measured battery charge at a present time and an estimated battery drain between the present time and the starting time of the scheduled program.

21. The apparatus of claim 18, further comprising means for determining at one or more times between receiving the user selection of the scheduled program and the starting time of the schedule program whether the battery charge is predicted to satisfy the battery charge threshold at the starting time of the scheduled program.

22. The apparatus of claim 18, further comprising means for preemptively canceling receipt of the scheduled program prior to receiving the scheduled program when an estimated battery charge or a measured battery charge does not satisfy the threshold battery charge.

23. A computer-readable medium comprising one or more computer-executable instructions, that when executed by a computing system, cause the computing system to:

receive a user selection of a scheduled program to be received at the mobile device;

determine a battery charge threshold based on at least one of a duration of the scheduled program and a processing complexity of the scheduled program;
