Particularly, in the embodiment of the present invention, a block diagram of a high definition television (HDTV) receiver employing a moving picture expert group (MPEG) standard is illustrated in FIG.

First, referring to the block configuration of the HDTV receiver 136, the tuner 102 receives a digital television broadcast signal received through the antenna 100 and selects a channel under the control of the microprocessor 124. Outputs an IF (Intermediate Frequency) signal according to the station. The IF module 104 converts the IF signal output from the tuner 102 into a baseband signal. The channel decoder 106 reproduces the data bit stream by channel decoding the baseband signal output from the IF module 104. The TS (Transport Stream) decoder 108 separates audio data, video data and additional data from the data bit string reproduced by the channel decoder 106. The audio data among the separated data is applied to the audio decoder 110, decoded according to the MPEG standard or the Dolby AC-3 standard, processed by the audio processing unit and the output unit 112, and then the speaker 114 is moved. Is output through voice. The video data is applied to the video decoder 116, decoded according to the MPEG standard, and applied to the OSG (On Screen Graphic) Mixer (118) to be combined with OSG data under the control of the microprocessor 124 to process the video and After processing at the output unit 120 is output on the screen through the water pipe (122). The OSG data is data for the microprocessor 124 to display various types of information on the screen as a graphic or a text.

The microprocessor 124, which is a control unit of the HDTV receiver 136, includes a keypad 130 and an infrared receiver 132 through a user interface 128. The IR transmitter 134 is connected. The microprocessor 124 performs an operation according to a command input from the remote controller 148 through the keypad 130 or the IR receiver 134 according to a program stored in the memory unit 126, and through the IR transmitter 134. Various additional information is transmitted to the remote controller 148. In addition, the memory unit 126 may include a read only memory (ROM) for storing a program of the microprocessor 124 and a random access memory (RAM) for temporarily storing data according to program execution of the microprocessor 124. Memory) and EEPROM (Electrically Erasable And Programmable ROM) for storing various reference data.

Referring to the block configuration of the remote controller 148, the microcomputer 138 generates an overall control signal to each part of the remote controller 148, and corrects the time of the remote controller 148 according to the time information provided from the HDTV receiver 136. do. The IR receiver 140 receives time data applied as an infrared signal from the HDTV receiver 136 and applies it to the microcomputer 138. The IR transmitter 142 transmits various numeric and function key signals of the remote controller 148 to the IR receiver 134 of the HDTV receiver 136 as an infrared signal. The key input unit 144 has a plurality of numeric keys and function keys, and applies key data according to the key input to the microcomputer 138. The display unit 146 displays the current time and various states of the remote controller 148.

2A is a flowchart illustrating a process of transmitting current time information from a HDTV receiver to a remote controller according to an exemplary embodiment of the present invention. The operation according to the flowchart of FIG. 2A is programmed in the memory unit 126 to be performed by the microprocessor 124 of FIG. An embodiment of the present invention will now be described in detail with reference to FIGS. 1 and 2A.

First, the microprocessor 124 of the HDTV receiver 136 checks whether a power key is input from the remote controller 148 in step 200. At this time, if the power key is input from the remote controller 148, the microprocessor 124 proceeds to step 202 to check whether the power of the current HDTV receiver 136 is in the "on" state. At this time, if the power of the HDTV receiver 136 is "on" state, that is, the HDTV receiver 136 is turned on, the microprocessor 124 proceeds to step 204 to "turn off" the power of the HDTV receiver 136. Let's do it.

In contrast, if the power of the HDTV receiver 136 is in the "off" state, that is, the HDTV receiver 136 is turned off, the microprocessor 124 proceeds to step 206 to turn on the power of the HDTV receiver 136. "I will. In operation 208, the microprocessor 124 checks the current time from the time information provided from the broadcasting station, and then transmits information on the current time to the remote controller 148 in step 210. The microprocessor 124 proceeds to step 212 and checks whether there is any key input from the remote controller 148. When there is a key input, the microprocessor 124 returns to step 208 and again (208) to (212). Follow the steps. On the other hand, if no key is input from the remote controller 148, the operation ends. In the above, the microprocessor 124 is " on " whenever the power of the HDTV receiver 136 is " on " by the keypad of the HDTV receiver 136 or by the remote controller 148. In this state, whenever there is any key input from the remote controller 136, it is programmed in advance to transmit the current time information to the remote controller 136.

2B is a flowchart illustrating a process of newly updating a time of a remote controller according to current time information transmitted from an HDTV receiver according to an exemplary embodiment of the present invention. An embodiment of the present invention will now be described in detail with reference to FIGS. 1 and 2A.

First, the microcomputer 138 of the remote controller 148 checks whether current time information is received from the HDTV receiver 136 in step 300. If the current time information is received from the HDTV receiver 136, the microcomputer 138 proceeds to step 302 and newly corrects the time of the remote controller 148 to the current time received from the HDTV receiver 136. The microcomputer 138 proceeds to step 304 to display the newly corrected time on the display unit 146 of the remote controller 138.

Therefore, the time of the remote control is corrected to the current time transmitted from the HDTV receiver whenever the power of the HDTV receiver is "on" and whenever there is any key input from the remote control while the power of the HDTV receiver is "on". The time can always be kept accurate.

As described above, the present invention provides a remote control unit with an IR receiver unit and a television unit with an IR transmitter unit so that the remote control unit is controlled every time the power source of the television unit is "on" and the power source of the television unit is "on". There is an advantage that the time of the remote control can always be kept accurate by correcting to the current time transmitted from the television device whenever there is any keystroke from.
