The production, scheduling, transmission, and reception of content are all digitized. The Integrated Services Digital Broadcaster is a digital 15 broadcast system capable of transmitting multi-channel television programs, multimedia services, and other materials containing image text. The development of integrated service digital broadcasters is mainly in response to the era of digital broadcasting in the 2nd century. Integrated service digital broadcasters use MPEG-2 digital signal compression coding and multiplex technology, which can be transmitted via satellite or cable. Different transmission media broadcasts such as terrestrial wireless, the more fruitful one is the 1SDB-T system for terrestrial broadcasting. The ISDB-Τ system was officially publicized on November 12-14, 1997. On the following day, the Tokyo area began trial broadcast 'It uses the same 6MHz frequency as the current NTSC analog TV system' and 525 continuous scanning (pr〇gressive Scannjng) image format, which can not only transmit high-quality TV (HDTV) The program, in the anti-ghost and shift 5 1307243 analog TV system, Japan expects that the function of the official end of the market at the latest in 2012 is far better than the current official digital terrestrial TV broadcast in 2003.

In this way, the user can use this timer to perform the functions of making a reservation, or downloading digital program information. [Embodiment] This month is about a liquid crystal television device with two-stage power control. First, please refer to FIG. 1 for a system architecture diagram of a preferred embodiment, and FIG. 2 is a schematic diagram of a preferred embodiment of the present invention. Among them, the liquid crystal television device 1 includes a power supply device u, a micro control board 12, a side panel 13 remote controller 14, and a transmitting end 15. In this embodiment, the LCD TV device! It is used in conjunction with a DVD recorder 3, wherein the DVD recorder 3 includes a receiving end 31. In Fig. 1, a power supply device 11 is provided for supplying power to the liquid crystal television device 1. The micro control board 12 has a trigger pin 121 and an RS_232 interface 122. And the micro control board 12 is electrically connected to the power supply device 丨J. The RS-232 interface 122 includes a receiving end 123 (Rx), a transmitting end 124 (Τχ), 7 1307243, and a control ## end 125. In the present invention, the operation mode of the micro control board 12 includes a power on mode, a standby mode, and a power saving mode. In the present invention, the 'ISDB control board 13 is electrically connected to the micro control board 12, and transmits a predetermined potential to trigger the trigger pin 121 of the micro control board 12. The isdb 5 control board 13 includes a timer 13 and an RS-232 interface 132. The RS-232' interface 132 is provided with a receiving end 133, a transmitting end 134, and a control signal 135, the ISDB control board 13. The micro-control board 12 is connected to the micro-control board 12 via an rs-232 interface 132. The receiving end 123 of the micro-control board 12 is connected to the transmitting end 134 of the 181) 3 call control board 13; the transmitting end 124 of the micro-control board 12 is connected. To the receiving end 133 of the 10 ISE>B control board 13, the control signal terminal 125 of the micro control board 12 is connected to the control signal terminal 135 of the ISDB control board 13. The remote controller 14 wirelessly controls the operation of the micro control board 12 of the liquid crystal television device 1. The transmitting end 15 is electrically connected to the micro control board 12. Referring to Figure 3, a flow chart of a preferred embodiment of the present invention is shown. First, first, the timer 131 of the ISDB control board 13 is set, and the liquid crystal television device is turned off, and the micro control board 12 will enter a power saving mode to save power consumption. When the user sets the timer 131 of the 1SDB control board π, and the timer 131 § ten o'clock, the ISDB control board 13 sends a preset potential to the trigger pin 121 of the micro control board 12, thereby triggering the micro control board 12 When the pin 121 is triggered, the 20 micro-control board 12 will enter a standby mode, and the ISDB control board π transmits the program information to the micro-control board 12 through the RS-232 interface 132, and then outputs the output to the DVD recorder 3 via the transmitting end. End 31, and optionally send program information to a DVD recorder 3 for recording, or downloading a digital television program listing. In this 8 1307243, the pre-three potential of the trigger pin 121 sent by the ISDB control board 13 to the micro-control board 12 is a positive potential.
