Abstract

A device is provided for use with an audiovisual device and a cable having a first end and a second end. The audiovisual device can receive digital television audiovisual signals. The cable includes a data channel, a control channel and a power line and can transmit the digital television audiovisual signals. The first end can connect to the audiovisual device, whereas the second end can connect to the device. The device includes a connector, a detecting portion and a power source. The connector can connect to the second end. The detecting portion can generate a connection signal based on a connection of the connector to the second end. The power source can provide power based on the connection signal.

Claims (28)

1. A battery-powered mobile device comprising an audiovisual source, the battery-powered mobile device for use with an audiovisual sink device and with a cable having a first end and a second end, wherein:

the audiovisual sink device is configured to receive digital television audiovisual signals, and

the cable includes a data channel, a control channel and a power line; the cable being configured to transmit the digital television audiovisual signals, the first end being configured to connect to the audiovisual sink device for transmitting the digital television audiovisual signals from the cable to the audiovisual sink device, and the second end being configured to connect to the battery-powered mobile device for receiving the digital television audiovisual signals from the battery-powered mobile device;

the battery-powered mobile device comprising:

a connector configured to receive the second end of the cable and configured to connect to the cable, wherein the connector is configured, when connected to the cable, to transmit the digital television audiovisual signals from the battery-powered mobile device via the cable to the audiovisual sink device;

a detecting portion configured to generate a connection signal based on detection of a connection of the connector to the cable, wherein the detecting portion is configured to detect a change in voltage or current in a transition minimized differential signaling (TMDS) line communicatively coupled to the connector; and

a power source in the battery-powered mobile device, the power source configured to provide power from a battery, wherein the power source steps up a voltage of the power from the battery to a constant voltage of 5V and steps down a respective current of the power from the battery, the power being provided through the cable from the battery-powered mobile device to the audiovisual sink device based on the connection signal indicating connection of the connector to the cable.

2. The battery-powered mobile device of claim 1 , wherein the power source comprises a 5V charge pump.

3. The battery-powered mobile device of claim 1 , wherein the detecting portion comprises a comparator and a reference voltage supply mechanical switch.

4. The battery-powered mobile device of claim 1 , wherein the detecting portion comprises a comparator and a reference voltage supply.

5. The battery-powered mobile device of claim 4 , wherein the detecting portion further comprises:

a mechanical switch for generating the connection signal based on the connection of the connector.

6. The battery-powered mobile device of claim 5 , wherein the connection signal comprises an enable signal configured to enable the power source to provide power.

7. The battery-powered mobile device of claim 4 , wherein the connector is configured to provide a signal when connected to the cable, wherein the comparator is arranged to compare a voltage from the reference voltage supply with the signal, and

wherein the comparator is configured to output the connection signal based on the comparison.

8. The battery-powered mobile device of claim 7 , wherein the connection signal comprises an enable signal configured to enable the power source to provide power.

9. A method of using an audiovisual sink device and a cable having a first end and a second end, the audiovisual sink device being configured to receive digital television audiovisual signals from a battery-powered mobile device comprising an audiovisual source, the cable including a data channel, a control channel and a power line and being configured to transmit the digital television audiovisual signals, the first end being configured to connect to the audiovisual sink device for transmitting the digital television audiovisual signals from the second end to the audiovisual sink device, the second end being configured to connect to the battery-powered mobile device for receiving the digital television audiovisual signals from the battery-powered mobile device, the method comprising:

connecting the cable to a connector of the battery-powered mobile device configured to receive the second end, wherein the cable is configured, when connected to the connector,

to transmit the digital television audiovisual signals from the battery-powered mobile device via the cable to the first end;

generating, by a detecting portion that is configured to detect a change in voltage or current in a transition minimized differential signaling (TMDS) line communicatively coupled to the connector, a connection signal based on the connection of the connector to the cable; and

providing power from a battery, via a power source in the battery-powered mobile device, wherein the power source steps up a voltage of the power from the battery to a constant voltage of 5V and steps down a respective current of the power from the battery, the power being provided through the cable from the battery-powered mobile device to the audiovisual sink device based on the connection signal indicating the connection of the connector to the cable.

10. The method of claim 9 , wherein the providing, via the power source, power based on the connection signal comprises providing, via a 5V charge pump, power based on the connection signal.

11. The method of claim 10 , wherein the detecting portion comprises a mechanical switch for generating the connection signal based on the connection of the connector to the cable.

12. The method of claim 10 , wherein the detecting portion comprises a comparator and a reference voltage supply for generating the connection signal based on the connection of the connector to the cable, the generating further comprising:

providing, via the connector, a signal when the connector is connected to the cable;

comparing, via the comparator, a voltage from the reference voltage supply with the signal; and

outputting, via the comparator, the connection signal based on the comparison.

13. The method of claim 12 , wherein the connection signal comprises an enable signal configured to cause the battery-powered mobile device to enable the power source to provide power.
