The present invention relates to a general telephone having a DMB receiver. More specifically, the DMB broadcasting can be viewed, and when a call is received during broadcasting, the call is displayed on a display, and data communication with an external device such as a TV or a computer is performed. A general telephone with a possible DMB receiver is provided.

Digital Multimedia Broadcasting (DMB), which allows users to watch broadcasts through DMB receivers, is emerging as a new concept of next-generation broadcasting that enables users to conveniently watch high-quality and high-quality broadcasts anytime, anywhere on the move. DMB is defined as' a digital multimedia broadcasting that can provide CD-level sound quality and data or video service, and provide excellent fixed and mobile reception quality'.DMB is further divided into terrestrial DMB and satellite DMB according to the data transmission method. do.

Terrestrial DMB uses only the network of the terrestrial network and uses frequencies corresponding to 174-216 MHz (42 MHz). This frequency range corresponds to over-the-air TV channels 7-13. Using this frequency domain, 18 CD-level audio channels can be obtained at a frequency of 6 MHz corresponding to one TV channel.

Satellite DMB will provide services using satellite networks and Gap Fillers. Satellite DMB uses frequencies from 2,605 to 2,655 MHz (50 MHz). It is possible to provide 10 or more video channels using this frequency domain.

The object of the present invention is to provide a general telephone with a DMB receiver having excellent economic feasibility by combining two functions by combining a DMB receiver and a general telephone which enables to watch a DMB broadcast as described above.

It is an object of the present invention to provide a general telephone with a DMB receiver that visually informs viewers that a call has been made by displaying a call when a call is received while watching a broadcast.

An object of the present invention is to provide a general telephone having a DMB receiver capable of data communication with an external device such as a TV or a computer by including a data transmission interface in the DMB receiver.

A general telephone having a DMB receiver of the present invention for achieving the above object,

A receiver which receives a broadcast signal transmitted from a satellite DMB broadcasting station or a terrestrial DMB broadcasting station;

A demodulator for demodulating the broadcast signal received by the receiver;

A demultiplexer for restoring the broadcast signal demodulated by the demodulator;

A decoder which decodes the broadcast signal encoded by the inverse weighting unit;

A video / audio processor for processing the broadcast signal decoded by the decoder to be output as video and audio; And

And an output unit configured to output an image and a sound through the display and the speaker by processing the broadcast signal processed by the image / audio processor.

And when the call is received while watching the DMB broadcast, characterized in that it further comprises a notification unit for displaying on the display of the output unit,

The DMB receiver further includes a data transmission interface to enable data communication with an external device.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, which shows a perspective view of a general telephone 1 having a DMB receiver 2 according to an example of the present invention, the present invention is integrated with a general telephone 1 and a DMB receiver 2. . More specifically, the telephone 1 is provided with a handset 16 and a keypad 19, like the conventional telephone 1, and has a DMB with the display 27a and the speaker 14 exposed to the outside. The receiver 2 is hinged to the general telephone 1 so that the viewer can adjust the angle at a comfortable viewing angle.

Hereinafter, a schematic block diagram of a general telephone 1 having a DMB receiver 2 according to the present invention will be described with reference to FIG.

The DMB receiver 2 includes a receiver 21 for receiving a multiplexed broadcast signal transmitted from a satellite DMB broadcast station or a terrestrial DMB broadcast station, and a demodulator 22 for receiving and demodulating the broadcast signal output from the receiver 21. (Demodulator), a demultiplexer (24) for receiving and restoring the demodulated broadcast signal of the multiplexed compressed state output from the demodulator (22), and output from the demultiplexer (24) A decoder 25 to decode the restored and encoded broadcast signal, and a video / audio processor to process the decoded broadcast signal output from the decoder 25 to be output as video and audio. And an output unit 27 for outputting a broadcast signal output through the video / audio processing unit 26 as an image and sound through the display 27a and the speaker 27b.

The data transmission interface 28 is connected to the output side of the demodulator 22. The data transmission interface 28 is composed of an I / O terminal, ear jack, multimedia terminal, IEEE1394, USB terminal, etc., and is connected to an external device 4 such as a TV or a computer to transmit data related to DMB broadcasting. do. In this case, data transmission from the data transmission interface 28 to the external device 4 is generally performed through a wire, but may be performed through a short range wireless communication such as Bluetooth.

The telephone 1 includes a connector C for connecting with a telephone line, a ring detector 11 for detecting a ring signal, and a hook switch 12 for switching a call enabled state by turning on / off a telephone receiver. And a DAA (Data Access Arrangement) 13 for appropriately controlling the impedance or current of the telephone set required by the telephone station, the telephone line in which the high voltage is generated, and the telephone operated at the low voltage in a circuit. The hybrid 14 for transmitting the caller information (CID) signal to the codec 15, the CID relay 17 for transmitting the CID signal from the telephone line to the hybrid 14 under the control of the microcomputer 18, and the telephone line. A voice processing codec 15 for processing voice signals input and output via the microcomputer 18, a microcomputer 18 for controlling each function of the telephone, a handset 16 for transmitting and receiving voices with the other party, a telephone number It comprises a keypad (19) comprising a letter and various function keys.

The microcomputer 18 of the telephone 1 and the display 27a of the DMB receiver 2 are connected via a notification unit 3. The notification unit 3 displays a call on the display 27a of the output unit 27 when a call is received while watching a DMB broadcast, so that the viewer does not hear the ringtone and does not receive a call. .

The telephone signal displayed on the display 27a will normally blink the text "Called (example)" with a color with excellent identifiability. It would be more desirable to include additional sender information here.

However, caller information is transmitted from the telephone company, and usually only limited information such as time, date, and phone number is transmitted. However, the receiver (ie viewer) needs more specific caller information. For example, we want caller information such as name, title, and relationship with the recipient.

In order to display more detailed caller information as described above, the notification unit 3 includes a memory 3a, which is connected to the keypad 19 through the microcomputer 18. The memory 3a stores a plurality of telephone numbers entered by the receiver through the keypad 19 and caller information (name, title, relationship, etc.) associated with each telephone number.

The notification unit 3 compares the telephone number transmitted from the telephone station with the telephone number stored in the memory 3a and displays the caller information for the matching telephone number on the display 27a.

In the above description of the present invention, a general telephone having a DMB receiver having a specific shape and structure has been described with reference to the accompanying drawings, but the present invention can be variously modified and changed by those skilled in the art. It should be interpreted as falling within the protection scope of the present invention.

As described above, the present invention integrates a telephone and a DMB receiver, which is excellent in economic efficiency, and when a call is received while watching a broadcast, the viewer visually displays the caller information including the caller information on the display so that the viewer cannot answer the call. It will prevent you from occurring.
