Abstract

According to one embodiment, a wireless transmission device includes: a transmitter that transmits a signal to an external device; an internal rechargeable battery that supplies a power to the transmitter; a connector to which an external rechargeable battery inserted from outside is connected; and a controller that controls the internal rechargeable battery and the external rechargeable battery so that the external rechargeable battery recharges the internal rechargeable battery when the external rechargeable battery is connected to the connector, wherein the external rechargeable battery is charged when the transmitter transmits the signal to the external device.

Claims

1. A wireless transmission device comprising:

a transmitter within a housing, the transmitter configured to transmit a signal to an external device;

an internal rechargeable battery with the housing, the internal rechargeable battery configured to supply power to the transmitter;

a connector associated with the housing, the connector configured to connect to an external rechargeable battery;

an external rechargeable battery configured to recharge the internal battery while the external battery is connected to the connector;

the external battery further configured to connect to the external device, and

a controller configured to control recharge of the internal rechargeable battery by the external rechargeable battery,

wherein the external rechargeable battery configured to be charged while the external rechargeable battery is connected to the external device, and while the transmitter transmits the signal to the external device.

2. The wireless transmission device of claim 1, wherein the external rechargeable battery is housed in a casing with a receiver configured to receive the transmission signal from the transmitter.

3. The wireless transmission device of claim 1, wherein the external rechargeable battery is configured to be charged by the external device.

4. The wireless transmission device of claim 2, wherein the casing comprises a casing connector configured to connect to the connector of the wireless transmission device.

5. The wireless transmission device of claim 1, wherein the connector is compliant with the USB standard, the IEEE 1394 standard, and/or the HDMI standard.

6. The wireless transmission device of claim 4, wherein the casing connector comprises a connector based on the USB standard, the IEEE 1394 standard, and/or the HDMI standard.

7. The wireless transmission device of claim 4, wherein the casing connector is configured to connect to the external device.

8. The wireless transmission device of claim 1, wherein the connector is configured to connect to the external device with a cable, and wherein the controller is configured to control the transmitter to transmit the transmission signal to the external device through the connector and the cable.

9. The wireless transmission device of claim 8, wherein the cable is compliant with the USB standard, the IEEE 1394 standard, and/or the HDMI standard.

10. The wireless transmission device of claim 1, wherein the connector is configured to connect to the external device with a cable, and wherein the controller is configured to control the internal rechargeable battery so that the external device recharges the internal rechargeable battery through the connector and the cable.

11. The wireless transmission device according to claim 10, wherein the cable is compliant with the USB standard, the IEEE 1394 standard, and/or the HDMI standard.
