Abstract

A system that incorporates teachings of the present disclosure may include, for example, a presentation device having a controller that performs operations including enabling a supply of power to a portable battery operated device from a presentation port where the presentation port is a high definition multimedia interface port by trickle charging a rechargeable battery of the portable battery operated device through the presentation port, and receiving from the portable battery operated device an audio-visual signal for presentation at the presentation device through the presentation port. Other embodiments are disclosed.

Claims

1. A set top box comprising:

a memory that stores instructions;

a high definition multimedia interface port;

a rechargeable battery coupled to the high definition multimedia interface port; and

a processor coupled to the memory, the high definition multimedia interface port, and the rechargeable battery, wherein responsive to executing the instructions, the processor performs operations comprising;

determining whether the high definition multimedia interface port receives power from an external source;

responsive to determining that the high definition multimedia interface port receives power from the external source;

receiving power from the high definition multimedia interface port, and

trickle charging the rechargeable battery via the high definition multimedia interface port.

2. The set top box of claim 1, wherein the high definition multimedia interface port receives power from the external source, and wherein the external source comprises a presentation device coupled to the set top box via the high definition multimedia interface port.

3. The set top box of claim 2, wherein the presentation device comprises a high definition television.

4. The set top box of claim 2, wherein the operations further comprise:

decoding audio-visual information into a high definition multimedia interface standard format;

generating a signal for presenting the audio-visual information at the presentation device; and

transmitting the decoded audio-visual information to the presentation device via the high definition multimedia interface port.

5. The set top box of claim 4, wherein the operations further comprise storing the decoded audio-visual information in the memory.

6. The set top box of claim 1, wherein the high definition multimedia interface port receives power from the external source, and wherein the operations further comprise determining whether the power is sufficient for operation of the set top box.

7. The set top box of claim 1, wherein the high definition multimedia interface port does not receive power from the external source, and the set top box is powered by the rechargeable battery.

8. The set top box of claim 1, wherein the operations further comprise:

interfacing with a communication device by way of a radio frequency or an infrared source of the set top box; and

interfacing with a communication network via a network interface of the set top box.

9. The set top box of claim 8, wherein the network interface comprises a wireless interface.

10. A media processor comprising:

a memory that stores instructions;

a first high definition multimedia interface port;

a rechargeable battery coupled to the high definition multimedia interface port; and

a processor coupled to the memory, wherein responsive to executing the instructions, the processor performs operations comprising;

determining whether the first high definition multimedia interface port receives power from an external source enabling trickle charging of the rechargeable battery; and

in response to determining that the first high definition multimedia interface port receives power from the external source;

receiving power via the first high definition multimedia interface port, and

trickle charging the rechargeable battery using a second high definition multimedia interface input port of a presentation device coupled to the media processor.

11. The media processor of claim 10, wherein the operations further comprise detecting whether the high definition multimedia interface port supplies sufficient power to enable the trickle charging of the rechargeable battery.

12. The media processor of claim 10, wherein the media processor is directly powered from the high definition multimedia interface port.

13. The media processor of claim 10, wherein the operations further comprise:

in response to detecting that the high definition multimedia interface port does not receive power from the external source, powering the media processor using the rechargeable battery.

14. The media processor of claim 10, wherein the presentation device comprises a high definition television.

15. The media processor of claim 10, wherein the operations further comprise:

decoding audio-visual information into a high definition multimedia interface standard format;

generating a signal for presenting the audio-visual information at the presentation device; and

transmitting the decoded audio-visual information to the presentation device via the high definition multimedia interface port.

16. A method comprising:

determining, by a processor, whether a high definition multimedia interface port of a portable set top box receives power from an external source; and

in response to determining that the high definition multimedia interface port receives power from the external source;

receiving, by the processor, inline power through the high definition multimedia interface port, and

charging, by the processor, a rechargeable battery by trickle charging using the inline power.

17. The method of claim 16 wherein, in response to determining that the high definition multimedia interface port does not receive power from the external source, the portable set top box is powered by the rechargeable battery.

18. The method of claim 16, wherein the external source comprises a presentation device coupled to the portable set top box via the high definition multimedia interface port.

19. The method of claim 18, wherein the presentation device comprises a high definition television.

20. The method of claim 16, further comprising determining whether the high definition multimedia interface port supplies sufficient power to enable the trickle charging of the rechargeable battery.
