Abstract

An apparatus for receiving an image signal for reproduction from a multimedia device, which includes an interface for outputting the image signal for reproduction to the outside, and wirelessly transmitting the image signal to the outside includes: an interface unit, which is combined with the multimedia device via the interface of the multimedia device and then receiving the image signal for reproduction; and a Radio Frequency (RF) transmitter for wirelessly transmitting the image signal, which has been received via the interface unit, using a predetermined channel of an Ultra High Frequency (UHF) band. A method of transmitting an image signal to an image device, which receives the image signal transmitted using a channel of a UHF band and displays an image corresponding to the image signal, includes the steps of: receiving an image signal for reproduction from a multimedia device for outputting the image signal for reproduction to the outside by being combined with the multimedia device; and wirelessly transmitting the received image signal via a predetermined channel of the UHF band.

Claims

1. An apparatus for transmitting an image signal to an image device, which receives the image signal transmitted using a channel of an Ultra High Frequency (UHF) band and displays an image corresponding to the image signal, the apparatus comprising:

a multimedia device including an interface for outputting the image signal for reproduction; and

a wireless transmission apparatus, which is combined with the multimedia device via the interface, which receives the image signal for reproduction and wirelessly transmits the image signal for reproduction via a predetermined channel of the UHF band.

2. The apparatus of claim 1, wherein the multimedia device is one of a mobile phone, a multimedia player, a computer, and a digital multimedia broadcasting (DMB) receiver.

3. The apparatus of claim 1, wherein the image device is a television.

4. The apparatus of claim 1, wherein the image device selects the predetermined channel to receive the image signal wirelessly transmitted from the wireless transmission apparatus.

5. The apparatus of claim 1, wherein the wireless transmission apparatus receives power via the interface of the multimedia device.

6. The apparatus of claim 1, wherein the multimedia device supplies power to the wireless transmission apparatus via the interface if the wireless transmission apparatus is combined with the multimedia device via the interface.

7. The apparatus of claim 1, wherein the wireless transmission apparatus receives power from a self power supply.

8. The apparatus of claim 1, wherein the image signal comprises an audio signal and a video signal.

9. An apparatus for receiving an image signal for reproduction from a multimedia device, which includes an interface for outputting the image signal for reproduction to the outside, and wirelessly transmitting the image signal, the apparatus comprising:

the interface unit, which is combined with the multimedia device via the interface of the multimedia device, and which receives the image signal for reproduction; and

a Radio Frequency (RF) transmitter for wirelessly transmitting the image signal, which has been received via the interface unit using a predetermined channel of an Ultra High Frequency (UHF) band.

10. The apparatus of claim 9, wherein the interface unit receives power from the multimedia device.

11. The apparatus of claim 9, further comprising a self power supply for supplying internal power.

12. A method of transmitting an image signal to an image device, which receives the image signal transmitted using a channel of an Ultra High Frequency (UHF) band and displays an image corresponding to the image signal, the method comprising the steps of:

receiving an image signal for reproduction from a multimedia device for outputting the image signal for reproduction by being combined with the multimedia device; and

wirelessly transmitting the received image signal via a predetermined channel of the UHF band.

13. The method of claim 12, wherein the multimedia device is one of a mobile phone, a multimedia player, a computer, and a digital multimedia broadcasting (DMB) receiver.

14. The method of claim 12, wherein the image device is a television.

15. The method of claim 12, wherein the image device selects the predetermined channel to receive the image signal wirelessly transmitted.

16. The method of claim 12, further comprising receiving power from the multimedia device.

17. The method of claim 12, further comprising receiving power from a self power supply.

18. The method of claim 12, wherein the image signal comprises an audio signal and a video signal.
