Abstract

Disclosed is a system and a method for receiving digital broadcasts by using a mobile communication terminal. The system includes a digital broadcast receiving device for receiving digital data from a contents provision unit by using a wired/wireless communication network and transmitting the digital data; and a mobile communication terminal for receiving the digital data from the digital broadcast receiving device, decoding the digital data, creating video and audio signals, and outputting the video and audio signals. The mobile communication terminal replaces circuits of the digital broadcast receiving device, which are in charge of predetermined functions. This simplifies the construction of the digital broadcast receiving device and reduces the cost for implementing the device.

Claims

1. A system for receiving and outputting digital data for digital broadcasts provided from a contents provision unit by using a wired/wireless communication network, the system comprising:

a digital broadcast receiving device for receiving the digital data from the contents provision unit by using the wired/wireless communication network and transmitting the digital data; and

a mobile communication terminal for receiving the digital data from the digital broadcast receiving device, decoding the digital data, creating video and audio signals, and outputting the video and audio signals.

2. A system for receiving and outputting digital data for digital broadcasts provided from a contents provision unit by using a wired/wireless communication network, the system comprising:

a digital broadcast receiving device comprising a wired/wireless communication unit for receiving the digital data from the contents provision unit by using the wired/wireless communication network, a receiver control unit for controlling data and signals of the digital broadcast receiving device, and a receiver short-range communication unit for transmitting the digital data; and

a mobile communication terminal comprising a terminal short-range communication unit for receiving the digital data from the receiver short-range communication unit, a terminal input unit for receiving an input of a command or data for controlling the mobile communication terminal, a terminal storage unit for storing the digital data, a terminal control unit for controlling data and signals of the mobile communication terminal, a terminal decoding unit for decoding the digital data, creating video and audio signals, and transmitting the video and audio signals, and a terminal output unit for receiving the video and audio signals and outputting images and sounds.

3. The system as claimed in claim 2, further comprising a video/audio output device for outputting images and sounds so that the terminal output unit transmits the video and audio signals to the video/audio output device and controls the video/audio output device to output images and sounds.

4. The system as claimed in claim 2, wherein the digital broadcast receiving device further comprises a receiver storage unit for storing the digital data.

5. The system as claimed in claim 2, wherein the digital broadcast receiving device further comprises a receiver input unit for receiving an input of a command or data for controlling the digital broadcast receiving device.

6. The system as claimed in claim 2, wherein the digital broadcast receiving device and the mobile communication terminal are adapted to confirm mutual connection, enter into a standby mode when mutual connection has been confirmed, and conduct communication with each other.

7. A method for receiving and reproducing digital data for digital broadcasts provided from a contents provision unit by using a wired/wireless communication network, a digital broadcast receiving device, and a mobile communication terminal, the method comprising the steps of:

(a) connecting the digital broadcast receiving device to the mobile communication terminal so that the digital broadcast receiving device and the mobile communication terminal enter into a standby mode;

(b) receiving the digital data from the contents provision unit via the wired/wireless communication network by the digital broadcast receiving device;

(c) receiving the digital data from the digital broadcast receiving device by the mobile communication terminal;

(d) decoding the digital data and creating video and audio signals by the mobile communication terminal; and

(e) outputting images and sounds based on the video and audio signals by the mobile communication terminal.

8. The method as claimed in claim 7, further comprising a step of (a1) receiving an input for watching real-time broadcasts or VOD by the digital broadcast receiving device after step (a).

9. The method as claimed in claim 8, further comprising a step of (b1) storing the digital data by the digital broadcast receiving device after step (b) when the digital broadcast receiving device has received an input for watching VOD in step (a1).

10. The method as claimed in claim 7, further comprising, after step (a), the steps of:

(a2) receiving an input for watching real-time broadcasts or VOD by the mobile communication terminal; and

(a3) transmitting a request for watching real-time broadcasts or VOD to the digital broadcast receiving device by the mobile communication terminal.

11. The method as claimed in claim 10, further comprising a step of (c1) storing the digital data by the mobile communication terminal after step (c) when the mobile communication terminal has received an input for watching VOD in step (a2).
