Abstract

Video signals for a mobile terminal are converted to accommodate reproduction by an alternative display terminal. The video signal is processed to provide a converted video signal appropriate for an alternative display terminal that is separate from the mobile terminal. This converted video signal is then provided for the alternative display terminal to accommodate the corresponding video display on a screen provided by the alternative (e.g., external) display terminal.

Claims

1. A method for processing signals to accommodate reproduction by an alternative display terminal, the method comprising:

receiving by a conversion module a video signal appropriate for displaying a video content on a mobile terminal, the video signal being received by the conversion module from a cellular network communication that is sent to the mobile terminal and then received by the conversion module;

processing by the conversion module the video signal to produce a converted video signal for use by the alternative display terminal, wherein processing by the conversion module includes converting the video signal from a compression format appropriate for the mobile terminal to a display format for the alternative display terminal that is different from the compression format, such that the converted video signal produced by the conversion module comprises a display format appropriate for driving the alternative display terminal; and

providing the converted video signal from the conversion module to the alternative display terminal to accommodate displaying the video content by the alternative display terminal.

2. The method of claim 1, wherein the mobile terminal is a cellular phone.

3. The method of claim 1, wherein the mobile terminal is a personal digital assistant.

4. The method of claim 1, wherein receiving the video signal, processing the video to produce the converted video signal, and providing the converted video signal to the alternative display terminal is performed using power from a source that differs from the internal power supply of the mobile terminal.

5. The method of claim 1, wherein the conversion module resides in the alternative display terminal.

6. The method of claim 1, wherein the video signal received is part of a multimedia signal that is received in the cellular network communication.

7. The method of claim 1, wherein the alternative display terminal is an external display terminal.

8. A system for processing signals to accommodate reproduction by an alternative display terminal, the system comprising:

means for receiving a video signal appropriate for displaying a video content on a mobile terminal, the video signal being received from a cellular network communication that is sent to the mobile terminal and then received by the means for receiving the video signal;

means for processing the video signal to produce a converted video signal for use by the alternative display terminal, wherein processing by the means for processing the video signal includes converting the video signal from a compression format appropriate for the mobile terminal to a display format for the alternative display terminal that is different from the compression format, such that the converted video signal produced by the means for processing the video signal comprises a display format appropriate for driving the alternative display terminal; and

means for providing the converted video signal to the alternative display terminal to accommodate displaying the video content by the alternative display terminal.

9. The system of claim 8, wherein the mobile terminal is a cellular phone.

10. The system of claim 8, wherein the mobile terminal is a personal digital assistant.

11. The system of claim 8, wherein receiving the video signal, processing the video to produce the converted video signal, and providing the converted video signal to the alternative display terminal is performed using power from a source that differs from the internal power supply of the mobile terminal.

12. The system of claim 8, wherein the means for receiving the video signal, means for processing the video signal to produce the converted video signal, and means for providing the converted video signal to the display terminal reside in a conversion module within the alternative display terminal.

13. The system of claim 8, wherein the video signal received is part of a multimedia signal that is received in the cellular network communication.

14. The system of claim 8, wherein the alternative display terminal is an external display terminal.

15. An apparatus for processing signals to accommodate reproduction by an alternative display terminal, the apparatus comprising:

an interface module, which receives a video signal appropriate for displaying a video content on a mobile terminal, the video signal being received from a cellular network communication that is sent to the mobile terminal and then received by the interface module;

a signal conversion module, in operative communication with the interface module, which processes the video signal to produce a converted signal for use by the alternative display terminal, wherein processing by the signal conversion module includes converting the video signal from a compression format appropriate for the mobile terminal to a display format for the alternative display terminal that is different from the compression format, such that the converted video signal comprises a display format appropriate for driving the alternative display terminal; and

a device interface module, in operative communication with the signal conversion module, which provides the converted video signal to the alternative display terminal to accommodate displaying the video content by the alternative display terminal.

16. The apparatus of claim 15, wherein the mobile terminal is a cellular phone.

17. The apparatus of claim 15, wherein the mobile terminal is a personal digital assistant.

18. The apparatus of claim 15, wherein power to receive the video signal, process the video to produce the converted video signal, and provide the converted video signal to the alternative display terminal is from a source that differs from the internal power supply of the mobile terminal.

19. The apparatus of claim 15, wherein the apparatus resides in the alternative display terminal.

20. The apparatus of claim 15, wherein the video signal received is part of a multimedia signal that is received in the cellular network communication.
