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 device, a video signal appropriate for displaying a video content on a mobile terminal, the video signal being sent from a wireless network communication;

processing, by the conversion device, the video signal to produce a converted video signal for use by the alternative display terminal, wherein processing by the conversion device includes converting a signal format appropriate for the mobile terminal to a display format for the alternative display terminal that is different from the signal format, the display format being a high definition digital format, such that the converted video signal produced by the conversion device comprises the high definition digital format for output to the alternative display terminal; and

providing the converted video signal from the conversion device 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 signal to produce the converted video signal, and providing the converted video signal to the alternative display terminal are 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 device resides in a housing of the alternative display terminal.

6. The method of claim 1, wherein the video signal received by the conversion device is part of a multimedia signal that is originally received by the mobile terminal in a cellular network communication before it is received by the conversion device from the mobile terminal.

7. The method of claim 1, wherein the wireless network communication includes a cellular network communication.

8. The method of claim 1, wherein providing the high definition format of the converted video signal from the conversion module to the alternative display terminal is through a high definition multimedia interface (HDMI).

9. The method of claim 1, wherein the conversion device resides in the mobile terminal.

10. The method of claim 1, wherein the conversion device includes the mobile terminal and an intermediary between the mobile terminal and the alternative display terminal.

11. A non-transitory computer readable medium storing program code for operating a conversion device, the program code being executable to perform operations comprising:

receiving, by the conversion device, a video signal appropriate for displaying a video content on a mobile terminal, the video signal being sent from a wireless network communication;

processing, by the conversion device, the video signal to produce a converted video signal for use by the alternative display terminal, wherein processing by the conversion device includes converting a signal format appropriate for the mobile terminal to a display format for the alternative display terminal that is different from the signal format, the display format being a high definition digital format, such that the converted video signal produced by the conversion device comprises the high definition digital format for output to the alternative display terminal; and

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

14. The computer readable medium of claim 11, wherein receiving the video signal, processing the video signal to produce the converted video signal, and providing the converted video signal to the alternative display terminal are performed using power from a source that differs from the internal power supply of the mobile terminal.

15. The computer readable medium of claim 11, wherein the conversion device resides in a housing of the alternative display terminal.

16. The computer readable medium of claim 11, wherein the video signal received by the conversion device is part of a multimedia signal that is originally received by the mobile terminal in a cellular network communication before it is received by the conversion device from the mobile terminal.

17. The computer readable medium of claim 11, wherein the wireless network communication includes a cellular network communication.

18. The computer readable medium of claim 11, wherein the high definition format of the converted video signal is a high definition multimedia interface (HDMI) format, and providing the converted video signal from the conversion device to the alternative display terminal is through an HDMI interface.

19. The computer readable medium of claim 11, wherein the conversion device resides in the mobile terminal.

20. The computer readable medium of claim 11, wherein the conversion device includes the mobile terminal and an intermediary between the mobile terminal and the alternative display terminal.

21. An apparatus for converting video signals, the apparatus comprising:
