Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. First, in adding reference numerals to the components of each drawing, it should be noted that the same reference numerals have the same reference numerals as much as possible even if displayed on different drawings. In addition, specific details appear in the following description, which is provided to help a more general understanding of the present invention, and the present invention may be practiced without these specific matters. Will be self-evident. In the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a block diagram of a wireless terminal capable of receiving television according to the present invention.

FIG. 1 illustrates an example in which a TV reception package 100 capable of HD TV reception using a MPEG (Moving Picture Expert Group) standard and a general wireless terminal 160 are connected as an example of a digital TV receiver.

In the television receiving package 100, a tuner 108 tunes an RF channel selected by a user in a broadcast reception signal through the antenna 106 according to the control of the microprocessor 126. The tuner 108 outputs the channel-selected intermediate frequency (IF) signal, converts the IF module 110 into a baseband signal, and outputs the signal to the channel decoder 112. The channel decoder 112 reproduces the TS (Transport Stream) data stream by channel decoding the baseband signal input from the IF module 110. The data stream thus reproduced is TS decoded by the TS decoder 114 and separated into audio data, video data, and additional data, respectively. The audio data is applied to the audio decoder 116, decoded according to the MPEG standard or the Dolby AC-3 standard, and transmitted to the controller 150 through the interface unit 127 processed by the audio processing and output unit 118. The controller passes through the signal processor 154. Output to the speaker. The video data is applied to the video decoder 120, decoded according to the MPEG standard, and applied to the OSG (On Screen Graphic) mixer 122 and merged with the OSG data under the control of the microprocessor 126 to be processed by the video processing and output unit 124. After that, the control unit 150 is transmitted through the interface unit 127 and the controller 150 is output on the screen through the display unit 152. The OSG data is data for the microprocessor 126 to display various types of information on a screen in a graphic or text form. The display unit 152 may receive a high-definition television as a thin film transistor (TFT) liquid crystal display (LCD). The microprocessor 126 of the television reception package 100 adjusts the channel according to the interface value inputted through the key input unit 151 through the interface unit 127. Real Time Clock (RTC) 138, coupled to microprocessor 126, provides current time data to microprocessor 126. As such, using the current time data provided from the RTC 138, the microprocessor 126 may provide a conventional time display or a program reservation service according to the present invention. The memory unit 128 includes a read only memory (ROM) for storing a program of the microprocessor 126, a random access memory (RAM) for temporarily storing data according to program execution of the microprocessor 126, and various references. EEPROM (Electrically Erasable and Programmable ROM) for storing data is provided. The interface unit 127 interfaces the audio processing and output unit 118, the video processing and output unit 124, and the signal output from the microprocessor 126 to the control unit 150.

The controller 150 of the wireless terminal controls the overall operation of the wireless terminal. The memory 153 includes a ROM that stores an operating program, an electrically programmable EEPROM, and a RAM. The display unit 152 is a display device capable of receiving high-definition television such as TFT LCD (THIN FILM TRANSIST0R). The display unit 152 displays the state of the wireless terminal or the progress of the program under the control of the controller 150 and displays an image in the television reception mode. The key input unit 151 includes a plurality of numeric keys and function keys for performing various functions, and outputs key data to the controller 150 by an external operation. The RF unit 150 is controlled by the controller 150 and transmits a signal to the base station. In addition, the RF unit 150 converts and outputs a radio signal received through the antenna. The signal processor 140 modulates the voice signal input from the microphone and converts the voice signal into voice data, demodulates the voice data input from the RF unit 150 into a voice signal, and outputs the voice signal through the speaker.

2 is a control flowchart for performing a television function according to an embodiment of the present invention.

In step 200, the controller 150 determines whether a key for selecting a television reception mode is input through the key input unit 151. When the key is input, in step 210, the controller 150 controls the microprocessor 126 of the television reception package 100 through the interface unit 127 to perform a television reception operation. In this case, the controller 150 selects a channel to be received through the microprocessor 126 according to a specific key value input through the key input unit 151. In addition, the controller 150 adjusts and outputs the volume output to the speaker according to a specific key value input through the key input unit 151. In step 220, the controller 150 determines whether a key for ending the television reception mode is input through the key input unit 151. If a key for terminating the television reception mode is input, in step 240, the controller 150 terminates the television reception mode and performs a call function of the terminal. If the end key is not input, the controller 150 checks whether there is a call in step 230. If there is a call, the flow proceeds to step 240;

In the present embodiment, the built-in form of the terminal is taken as an example. However, if the television reception package has a connection terminal for connecting with the wireless terminal 160, and the wireless terminal 160 has a connection terminal for connecting with the television reception package, Receive package is independent and can be used by plugging in the external TV receiving package as needed.

Meanwhile, in the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the present invention has a merit that a user can receive a television as well as a communication which is a function unique to the terminal through the terminal by receiving a television with a television reception package in the wireless terminal.
