Description

셋탑박스와 전원선을 이용한 가전기기의 시간세팅방법Time setting method of home appliance using set top box and power line

본 발명은 가전기기의 시간세팅방법에 관한 것으로서, 더욱 상세하게는 셋탑박스가 수신하는 앰펙(MPEG)데이터 중에서 현재시간에 대한 정보를 이용하여 가정내 가전기기의 현재시간을 전원선을 통신선로로하여 세팅할 수 있는 셋탑박스와 전원선을 이용한 가전기기의 시간세팅방법에 관한 것이다.The present invention relates to a time setting method of a home appliance, and more particularly, using the information on the current time of the MPEG data received by the set-top box to the current time of the home appliance in the power line communication line It relates to a time setting method of a home appliance using a set-top box and a power line that can be set.

일반 가전기기들에는 마이컴을 이용하여 다양한 기능들을 수행하고 있는 바, 예약기능을 가진 가전기기들은 현재 시간이 정확해야 사용자가 원하는 기능을 정확한 시간에 동작시킬 수 있다, 그러나, 초기에 가전기기를 설치할 때 정확한 시간을 세팅한다하더라도, 시간이 경과하면 오차가 발생하거나, 정전이 되면 현재시간을 잃어버리게 된다. 따라서, 사용자는 시간을 재설정해야 하는 번거로움이 있다.In general home appliances, a variety of functions are performed using a microcomputer, and home appliances with a reservation function can operate a desired function at an accurate time only when the current time is correct. Even if the correct time is set, an error occurs when time passes or the current time is lost when a power failure occurs. Therefore, the user has a hassle to reset the time.

또한, 동축케이블이나 광케이블과 같은 넓은 대역을 전송할 수 있는 매체를 통해 영상/음성과 같은 정보를 가입자에게 전송하기 위해 출현된 CATV(Community Antenna Television)는 초기에 난시청 해소를 목적으로 공용안테나를 설치하여 텔레비전방송을 가입자에게 단순히 전송하는 방식으로 시작하였으나. 현재에는 단순한 분배서비스를 넘어서 가입자에게 자주방송, 홈쇼핑등과 같은 쌍방향기능을 첨가하여 미래 정보화사회를 앞당기는 중요한 미디어로 떠오르고 있으며, 최근에는 공중파 전파에 의한 텔레비전 방송에 대응하여 케이블을 이용한 텔레비전이라는 의미로써 CABLE TELEVISION 약자로써 사용되고 있다. 이와 같은 CATV를 시청하기 해서 사용자는 아날로그신호로 처리되는 일반 텔레비전수상기외에도 디지털로 전송된 영상/음성데이터를 복원하여 일반 텔레비전수상기에서 인식할 수 있는 신호로 변환하는 역할을 하는 셋탑박스를 구비해야한다. 이 셋탑박스의 주요기능은 MPEG 방식으로 압축된 영상신호를 복호(Decoding), 복조(Demodulation), 신장(Decompression)하는 것이나, 이는 전송매체별 전송방식에 따라 다소 차이가 있다.In addition, CATV (Community Antenna Television), which emerged to transmit information such as video / audio to subscribers through a medium capable of transmitting a wide band such as coaxial cable or optical cable, initially installed a common antenna for the purpose of eliminating astigmatism. We started by simply sending television broadcasts to subscribers. Nowadays, it is emerging as an important media to advance the information society by adding two-way functions such as independent broadcasting and home shopping to subscribers, beyond the simple distribution service. In recent years, it is a television using cable in response to television broadcasting by airwaves. It is used as an abbreviation for CABLE TELEVISION. By watching such a CATV, the user should have a set-top box that restores the image / audio data transmitted digitally and converts the signal into a signal that can be recognized by the general television receiver in addition to the general television receiver processed as an analog signal. . The main function of the set-top box is to decode, demodulate, and decompress the video signal compressed by the MPEG method, which is somewhat different depending on the transmission method for each transmission medium.

또한, 이와 같은 MPEG 데이터에는 현재시간에 대한 정보가 수록되어 전송되어진다.In addition, such MPEG data includes information on the current time and is transmitted.

본 발명은 셋탑박스가 수신하는 앰펙(MPEG)데이터 중에서 현재시간에 대한 정보를 이용하여 가정내 가전기기의 현재시간을 전원선을 통신선로로하여 세팅할 수 있는 셋탑박스와 전원선을 이용한 가전기기의 시간세팅방법을 제공하는 것을 그 목적으로 한다.The present invention is a home appliance using a set-top box and a power line that can set the current time of home appliances using a power line as a communication line by using the information on the current time of the MPEG data received by the set-top box To provide a time setting method of the purpose.

도 3에 도시된 방법은 수신된 MPEG 데이터로부터 현재시간정보를 추출하는 과정(S300), 추출된 현재시간정보를 전원선모뎀을 통해 가전기기의 마이컴에 전달하는 과정(S302) 및 전달된 현재시간정보를 이용하여 자신의 현재시간정보를 갱신하는 과정(S304)으로 이루어진다.The method shown in FIG. 3 is a process of extracting current time information from received MPEG data (S300), a process of transferring the extracted current time information to a microcomputer of a home appliance through a power line modem (S302), and the current time delivered. In step S304, the current time information is updated using the information.

이어서, 도 1 내지 도 3을 참조하여 본 발명의 동작을 설명하면 다음과 같다.Next, the operation of the present invention will be described with reference to FIGS. 1 to 3.

수신된 MPEG 데이터로부터 현재시간정보를 추출한다.(S300) 즉, 데이터 수신부(100)는 네트웍이나 위성으로부터 영상과 음성데이터인 앰펙데이터를 수신하고 앰펙데이터 프레임 내에 Private 데이터 영역에는 각종 데이터를 실어 보낼 수 있는데 현재시간정보 및 방송프로그램에 대한 정보를 실어보낼 수 있다. 그중 현재시간정보를 추출한 앰펙복조부(101)가 인터럽트로 CPU(102)에 알리도록 설정한다.The current time information is extracted from the received MPEG data (S300). That is, the data receiving unit 100 receives amplification data, which are video and audio data, from a network or a satellite and sends various data to a private data area in the amplification data frame. It can send the current time information and information about the broadcast program. The amplifier demodulation unit 101, from which the current time information is extracted, is set to notify the CPU 102 by an interrupt.

S300과정에서 추출된 현재시간정보를 전원선모뎀(104)을 통해 가전기기의 마이컴(203)에 전달한다.(S302) 즉, 앰펙복조부(101)에서 현재시간정보 수신인터럽트가 발생하면, CPU(102)는 그 데이터를 복조부(101)로부터 수신하여 이를 현재시간정보 전송데이터로 가공하여 전원선모뎀(104)으로 전송하면, 이 신호는 전원부(103)의 전원선을 타고 가전기기로 전달된다. 따라서 도 2에 도시된 바와 같이 가전기기는 전원선모뎀(202)을 구비하고 있으므로, 전원부(201)의 전원선을 통해 입력되는 현재시간정보 신호를 가전기기의 마이콤(203)에 전달한다.The current time information extracted in step S300 is transmitted to the microcomputer 203 of the home appliance through the power line modem 104. (S302) In other words, if the current time information reception interrupt occurs in the amplifier demodulator 101, the CPU When 102 receives the data from the demodulator 101, processes the data into the current time information transmission data, and transmits the data to the power line modem 104, the signal is transmitted to the home appliance via the power line of the power supply 103. do. Therefore, as shown in FIG. 2, since the home appliance includes the power line modem 202, the home appliance transmits a current time information signal input through the power line of the power supply unit 201 to the microcomputer 203 of the home appliance.

S302과정에서 전달된 현재시간정보를 이용하여 자신의 현재시간정보를 갱신한다.(S304) 즉, 현재시간정보를 수신한 가전기기 마이콤(203)은 현재시간정보로 복구하여 자신의 시간데이터를 수정 또는 갱신한다.The current time information is updated by using the current time information transmitted in step S302 (S304). That is, the home appliance micom 203 which receives the current time information recovers the current time information and corrects its own time data. Or update.

상술한 바와 같이 본 발명에 따른 셋탑박스와 전원선을 이용한 가전기기의 시간세팅방법에 의하면, 셋탑박스와 가전기기간에 데이터를 전달하기 위한 통신선을 설치할 필요가 없으며, 정전시 가전기기 마이콤이 리셋되어 현재시간을 잃어버렸을 경우에도 셋탑박스가 동작하게 되면 현재시간에 대한 정보를 수신할 수 있으므로 사용자가 현재시간을 재설정하지 않아도 되며, 특히 현재시간을 기준으로 예약녹화등을 수행할 때, 정확한 현재시간을 설정할 수 있는 편리함을 제공한다.As described above, according to the time setting method of the home appliance using the set top box and the power line according to the present invention, there is no need to install a communication line for transferring data between the set top box and the home appliance, Even if the current time is lost, the set-top box can receive information about the current time when the set-top box is operated so that the user does not have to reset the current time. Particularly, when the scheduled recording is performed based on the current time, Provides the convenience of setting.
