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 method, comprising:

transmitting a high definition multimedia interface signal containing decoded audio-visual information in a high definition multimedia interface standard format from a portable set top box device to a presentation device by way of a high definition multimedia interface port of the portable set top box device, wherein the portable set top box device comprises a rechargeable battery; and

powering the portable set top box device inline through the high definition multimedia interface port of the set top box device, wherein the powering comprises powering the rechargeable battery by way of trickle charging using a high definition multimedia interface input port of the presentation device responsive to the portable set top box device being coupled to the presentation device.

2. The method of claim 1, comprising interfacing with a communication device by way of a radio frequency or an infrared source of the portable set top box device.

3. The method of claim 1, comprising interfacing with a communication network via a network interface of the portable set top box device.

4. The method of claim 1, comprising storing audio-visual content in a digital video recorder hard drive within the portable set top box device.

5. The method of claim 1, wherein the presentation device is a high definition television that has the high definition multimedia interface port that powers the portable set top box device inline through the high definition multimedia interface of the portable set top box device.

6. The method of claim 1, comprising decoding in the portable set top box device audio-visual information into the high definition multimedia interface standard format to generate the high definition multimedia interface signal.

7. The method of claim 6, comprising detecting, by the portable set top box device, one of:

whether the high definition multimedia interface port supplies sufficient power to enable the trickle charging of the rechargeable battery;

direct powering of the portable set top box device from the high definition multimedia interface port;

or whether the rechargeable battery solely powers the portable set top box device.

8. A non-transitory computer-readable storage medium, comprising computer instructions that, when executed by one or more processors, causes the one or more processors to perform operations comprising:

decoding audio-visual information into a high definition multimedia interface standard format in a portable standalone battery operated device; and

generating a signal used for presentation of the decoded audio-visual information on a presentation device, wherein the portable standalone battery operated device is at least partially powered by the presentation device responsive to the portable standalone battery operated device being coupled to the presentation device;

enabling the application of power to the portable standalone battery operated device inline through a high definition multimedia interface port on the portable standalone battery operated device, wherein the presentation device is a high definition television that has a high definition multimedia interface input port; and

enabling the trickle charging of a rechargeable battery of the portable standalone battery operated device using the high definition multimedia interface input port of the high definition television.

9. The non-transitory computer-readable storage medium of claim 8, comprising computer instructions for enabling the receipt of power at the portable standalone battery operated device when coupled to the presentation device through the high definition multimedia interface input port which transmits the signal containing the decoded audio-visual information in the high definition multimedia interface standard format to the presentation device.

10. The non-transitory computer-readable storage medium of claim 9, comprising computer instructions for interfacing with a communication device using a radio frequency or an infrared source of the portable standalone battery operated device to enable remote control of the portable standalone battery operated device.

11. The non-transitory computer-readable storage medium of claim 9, comprising computer instruction for interfacing with a communication network via a network interface in the portable standalone battery operated device.

12. The non-transitory computer-readable storage medium of claim 8, comprising computer instruction for storing audio-visual content in a digital media recorder in the portable standalone battery operated device.

13. The non-transitory computer readable storage medium of claim 8, wherein the portable standalone battery operated device is a portable set top box device.

14. The non-transitory computer-readable storage medium of claim 13, comprising computer instruction for enabling powering the portable standalone battery operated device with the rechargeable battery when the high definition multimedia interface port is not externally powered.

15. The non-transitory computer-readable storage medium of claim 13, comprising computer instruction for detecting one of:

whether the high definition multimedia interface input port supplies sufficient power to enable trickle charging of the rechargeable battery;

direct powering of the portable set top box device from the high definition multimedia interface input port;

or whether the rechargeable battery solely powers the portable set top box device.

16. A presentation device, comprising:

a memory storing computer instructions; and

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

enabling a supply of power to a portable battery operated device through a presentation port, wherein the presentation port is a high definition multimedia interface port, wherein the supplying of power comprises 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.

17. The presentation device of claim 16, wherein the controller, responsive to executing the computer instructions, performs operations comprising presenting the audio-visual signal on a display of the presentation device.

18. The presentation device of claim 17, wherein the presentation device corresponds to a portable television and wherein the portable battery operated device comprises a set top box.

19. The presentation device of claim 17, wherein the presentation device comprises a non-portable television.

20. The presentation device of claim 16, wherein the presentation port supplying power to the portable battery operated device trickle charges the rechargeable battery in the portable battery operated device through the high definition multimedia interface port and receives the audio-visual signal for presentation as decoded audio-visual information in the high definition multimedia interface format.
