BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile communication terminal, and more particularly, to a mobile communication terminal that receives and reproduces a video signal from the outside.

BACKGROUND ART In general, mobile communication devices such as mobile phones and PDAs have been developed to provide not only simple voice information but also text information, image information, and games to users. In addition, recently, an audio player function capable of reproducing an audio file such as an MP3 file and a digital camera function capable of capturing digital photos and images have been combined in a mobile communication terminal. Thus, the mobile communication terminal, which is being expanded in this way, is now a necessity of life.

In addition, the mobile communication terminal performs a function of playing a broadcast. More specifically, as a digital multimedia broadcasting (DMB), DMB originally started with the digital audio broadcasting (DAB) described above aiming at digital conversion of radio broadcasting, but is a comprehensive mobile multimedia service including video as well as voice.

DMB is a broadcast providing CD quality sound and data or video service through a mobile terminal in a mobile or fixed location. It is divided into terrestrial DMB and satellite DMB according to the transmission means.

DMB started with the intention to promote the digital conversion of domestic broadcasting media from the national level to increase the efficiency of frequency resource utilization and the digital conversion of terrestrial, satellite, and cable TV in earnest, and to radio broadcasting, which is the late digitization area.

It also means expanding the opportunities for new business participation by broadcasters such as terrestrial broadcasters and broadcasting channel operators (PPs), as well as wider choices for audiences and listeners.

As the government policies and detailed technical standards for terrestrial digital multimedia broadcasting (DMB) are gradually completed, companies in this field are actively developing terrestrial DMB equipment and solutions. Therefore, many products incorporating DMB in mobile communication terminals have been released.

Referring to FIG. 1, the mobile communication terminal is provided with a button 1 for executing DMB. When the button 1 is pressed, the DMB viewing menu is activated, and the user finds and executes a desired item. In this case, when the user is provided with an antenna to be drawn out in the mobile communication terminal, the user may watch the DMB by drawing out the antenna. Alternatively, the user may watch the DMB only by separately coupling an antenna to the mobile communication terminal. In other words, the user must perform the double operation of having to pull out or combine the click of the button 1 and the antenna.

The present invention has been made to solve the above-described problem, and provides a mobile communication terminal performing DMB when combining or drawing antennas.

One embodiment of the present invention provides a housing, an image display unit provided at one side of the housing, a processor provided inside the housing and receiving an image signal from the outside and outputting the image signal to the image display unit, an antenna drawn from the housing, and whether the antenna is drawn out. It provides a mobile communication terminal comprising a sensor for detecting a; and a controller for receiving whether the antenna is drawn from the sensor to drive the processor.

The controller may drive the processor when the antenna is drawn out.

On the other hand, another embodiment of the present invention is a housing, an English trademark portion provided on one side of the housing, a processor provided inside the housing and receiving an image signal from the outside and outputting the image signal to the image display portion, and detachably attached to one side of the housing. Provides a mobile communication terminal comprising an antenna coupled, a control unit for receiving the coupling of the antenna from the sensor to drive the processor.

The controller may drive the processor when the antenna is coupled.

In addition, the mobile communication terminal is characterized in that it further comprises a sensor for measuring whether the antenna is coupled.

In addition, the sensor is characterized in that consisting of a magnetic sensor.

Hereinafter, with reference to the accompanying drawings, embodiments of the present invention can be specifically realized the above object. In describing the present embodiments, the same names and symbols are used for the same components, and additional description thereof will be omitted.

In the present invention, the mobile communication terminal will be described taking a folder type mobile communication terminal as an example. Of course, the present invention can be applied to various types of mobile communication terminals, such as a slide type mobile communication terminal and a bar type mobile communication terminal.

The exterior of the mobile communication terminal 100 is formed by a housing 110. The housing 110 is made of one in the bar type, but made of two or more in the slide or clamshell. Since the clamshell mobile communication terminal 100 is described in the present invention, the housing 110 includes two or more. Here, the case where the housing 110 is composed of two will be described.

2 and 3 illustrate a mobile communication terminal 100 according to a first embodiment of the present invention.

The housing 110 forms an exterior of the mobile communication terminal 100 and includes a first housing 111 and a second housing 112 coupled to each other by a hinge.

 The first housing 111 is provided with an image display unit. The image display unit not only provides the user with the status and operation status of the mobile communication terminal 100, but also provides a video.

A battery pack for supplying electricity to one side is coupled to the second housing 112. And one side of the second housing 112 is provided with a keypad for the user to input a command. Here, when the first housing 111 and the second housing 112 are folded, the image display unit and the keypad are positioned in the first housing 111 and the second housing 112 to face each other. do.

In addition, the second housing 112 includes a main board and a mobile communication signal processor and a controller 150 mounted on the main board. Although not shown, the mobile communication signal processor includes a transmission signal processor (not shown) for processing and transmitting information input through the keypad and a reception signal processor (not shown) for receiving and processing radio waves from the outside. Transmitting and receiving circuits are provided. Here, since the configuration of the mobile communication signal processing unit and the control unit 150 for controlling them is similar to that provided in the conventional mobile communication terminal 100, further description thereof will be omitted.

In addition, a speaker and a microphone are provided in the first housing 110 and the second housing 112, respectively, so that a user can transmit and receive a voice through a mobile communication signal processor.

In addition, the mobile communication terminal 100 includes a processor 120 for receiving an image signal from the outside and outputting the image signal to the image display unit. Among the types of the processor 120, for example, DMB is called. DMB is an acronym for English Digital Multimedia Broadcasting. It is a new concept of mobile multimedia broadcasting service that combines broadcasting and communication. It is divided into terrestrial DMB and satellite DMB according to transmission method and network configuration.

DMB is called next-generation broadcasting service because it can provide CD quality sound and data service, and can watch multi-channel multimedia broadcasting while moving through mobile phone, PDA or car receiver.

The characteristics of terrestrial DMB and satellite DMB are as follows. Terrestrial DMB uses Eureka-147, the technical standard for European digital radio broadcasting (DAB), as its standard. As of 2004, the VHF No. 12 channel, which is empty, is used for multimedia broadcasting for mobile reception. If one channel is split, three blocks are generated, and each video and audio channel is generated per block. The frequency used by the DMB is 174-216 MHz, and the compression scheme uses MPEG4 technology. The radio waves used by DMB have diffraction characteristics suitable for long distances.

On the other hand, satellite DMB, unlike terrestrial DMB, uses satellites to provide broadcasting services. Therefore, urban areas with low reception receive broadcasts using a repeater called a gap filler. The frequency is more than 2.605 kHz, and the compression method is the same as the terrestrial wave.

On the other hand, in order to watch the DMB, the housing 110, among which the second housing 112 is provided with an antenna 130 which is drawn out. The antenna 130 is usually located inside the housing 110, and when the user views the DMB, the user draws it to the outside. Here, the antenna 130 may be used in common with the mobile communication signal processor.

The controller 150 determines whether the antenna 130 is withdrawn, and drives the processor 120. To this end, the mobile communication terminal 100 includes a sensor 140.

The sensor 140 is embedded in the housing 110, in more detail, the second housing 112, and detects whether the antenna 130 is withdrawn and transmits the result to the controller 150. Here, the sensor 140 is made of a magnetic sensor 140.

The controller 150 receives whether the antenna 130 is withdrawn from the sensor 140, and determines whether to drive the processor 120. Here, the controller 150 drives the processor 120 when the antenna 130 is drawn out. That is, when the user draws out the antenna 130, the controller 150 drives the processor 120 to watch the DMB even if the user does not input a separate command.

Meanwhile, when the mobile communication terminal 100 is stored in a bag or a pocket, the antenna 130 may be pulled out due to friction or hooking. The case of driving 120 occurs. To prevent this, the controller 150 drives the processor 120 when the antenna 130 is completely drawn out. In this case, the sensor 140 may continuously transmit the drawing state of the antenna 130 to the controller 150, and may transmit the state in which the antenna 130 is completely drawn out to the controller 150. Therefore, the controller 150 determines the position of the antenna 130 from the sensor 140 to determine whether to drive the processor 120.

Next, a second embodiment of the present invention will be described with reference to FIG. Here, the housing 110, the image display unit, the keypad, the battery pack and the like are the same as in the first embodiment, and are omitted in order to avoid redundant description.

In the mobile communication terminal 100 according to the second embodiment, the antenna 130 is coupled to one side. In addition, the controller 150 determines whether the mobile communication terminal 100 is coupled, and drives the processor 120.

Here, the controller 150 continuously sends a current to the antenna 130 to determine whether the antenna 130 is coupled, and if the current flows, the antenna 130 is coupled, and if not, the antenna 130 ) Can be determined not to be combined. Alternatively, the mobile communication terminal 100 may include a sensor 140, and measure whether the sensor 140 is coupled by the sensor 140 to the controller 150.

The controller 150 receives the coupling of the antenna 130 from the sensor 140 to drive the processor 120. Of course, the controller 150 drives the processor 120 when the antenna 130 is coupled.

As described above, the mobile communication terminal according to the present invention drives the processor for broadcasting by drawing an antenna without an overlapping operation, thereby providing convenience to the user.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the embodiments, but should be defined by the claims.
