Since the digital television receiver of the present invention has precise power management, it can meet the special power supply specifications of the handheld device. The main technical means for achieving the foregoing objective is that the digital television receiver includes a body. The body is mainly provided with a connector and an antenna connector. The connector includes a power input pin 'a set of signal access terminals. The foot is further divided into: a digital television processor, which mainly comprises more than one power input end, more than one data access end and one or more signal receiving end, wherein a data access end is connected to the connector a signal receiving pin connection; an RF receiving module having an input end, more than one output end and a power input end 'the input end is connected to the antenna connection on the body, and the output end is connected to the digital TV processing The signal receiving end of the device; an authentication chip having an input end, an output end and a power input end, wherein the input end and the output end are respectively connected to the data access end of the digital television processor: a switched power conversion mode Group 'It has a power input and more than one power output'. The power input is connected to the power output of the connector M421659 The consumption is less than 10 milliamperes. Therefore, in the embodiment, when the digital television receiver is electrically connected with the handheld device, the communication mode between the digital television receiver and the handheld device adopts a universal asynchronous transmission receiving (uart) interface. The universal asynchronous transmission reception enables the digital television receiver to switch to the low power mode, so that the current consumed is less than 5 milliamps, and the digital television reception is received when the software of the handheld device is activated and begins to watch the digital television. The device switches to the normal mode through the universal asynchronous transfer receiving interface, and the current consumption thereof is about 97 milliamperes as described above, and the antenna 121 of the digital television receiver receives less than the digital signal or the software of the handheld device. When turned off, the digital TV receiver is switched to the low power mode through the universal asynchronous transmission reception, thereby further improving the power management efficiency. A further preferred embodiment of the present invention further provides a function of charging the handheld device. To implement the above functions, a power supply 13 is further disposed on the body 10 as shown in FIG. The power port 13 is a Micro USB interface having a power pin (VBUS). The power pin (VBUS) will provide a DC power supply (USB 5.0) and provide a charging signal (Charger ON). The digital television processor 20' is provided to the digital television processor 20 to determine whether the power port 13 is input with power to charge the handheld device. In this embodiment, the power pin (VBUS) of the power port 13 is further connected to the power output (5.0V) of the connector 11 through a protection device module 70 to prevent the output power source from overvoltage or overcurrent. Avoid damage to the handheld device. As shown in FIG. 4 , the protection device module 70 includes a detection device 71 , a power system 7 2 and an electronic switch 73 . The device 71 is configured to connect and detect the power input. The USB5.0V is 9 M421659. There is more than the rated voltage or current, and it is decided whether to drive the electronic switch 73'. In this embodiment, the electronic switch 73 is composed of a reinforced nm〇S, and its gate system and detector The wheel-out terminal of the measuring device 71 is connected, and the drain electrode is connected to the enabling end of the power system 72. The power system 72 converts the input power source USB5.0V of the power port 13 to the connector 11 through the connection. The device 1 1 charges the handheld device; as described above, if the detecting device 71 detects that the input power USB5.0V is abnormal, the electronic switch 73 pulls the voltage of the power pin (VBUS) of the power port 13 to the ground. On the contrary, the input power (USB5.0V) is outputted through the power supply system 72 to a stable voltage to be connected to the power output pin (5·0ν) of the connector 11 to charge the handheld device. In this way, when the environmental conditions permit, the handheld device can charge at the same time when viewing the digital television to supply a sufficient power to the handheld device.
