New description: [New technical field] The burial device is especially concerned with the case of stealing the detection unit and depending on whether the system has illegally stolen, and [previous technology] The tree of Wei Wei Tong has a program message and a lambda device.

TV channel signal. # [New content] The main purpose of this creation is to provide a cable TV system with theft detection device. The cable TV system is equipped with a pirate detection unit. The pirate detection unit mainly uses partial pressure. The device monitors and detects whether there is any disconnection, theft or other load abnormality. Once one of the above conditions occurs, the device will automatically stop immediately. Video signal to the user TV, because the video signal has been cut off, even if the knife device and the cable are reconnected, the user's TV can't display the image because the video signal is cut off. The only way is to Through the cable TV system operators will re-set the control unit, so cable TV system operators can make appropriate arrangements through telephone contact or on-site to find out the situation that cannot be viewed. The cable TV system's stolen detection provided by this creation The device, once it detects that there is a phenomenon of partial pressure abnormality, stops transmitting the video signal to the abnormal user terminal, unless there is a Wei Shi clerk who relies on the green condition and resets the (4) end, otherwise there is no • _Identified the problem that the technique does not record the money and make proper disposal, in order to maintain the rights of the paying user and the #. [Embodiment] The following is a more detailed description of the implementation of the creation with the schema and the symbol. Explain that 'the skilled person can implement this manual after studying this manual. Refer to the figure, the schematic diagram of the stolen detection device of the cable TV system of this creation. As shown in the first figure, the pirate detection device of the cable television system of the present invention includes at least a hacking detection unit 10, a control unit 3, and a signal output control unit 4 M435789. The (10) television system axis further includes other units. However, it does not affect the following two Hi-maps, and the creation of the stolen detection unit and the signal rotation control unit recognizes the β circuit diagram. It should be noted that the second picture is used to illustrate the creation of this work, and it is not the rib to limit the difficulty of this creation. Therefore, this creation is the other circuit design of the package. Referring to the second figure and please cooperate with the first figure, the created pirated 1 〇 TV LTV is connected with a voltage dividing device 6 〇, the pirate detection list: there is a wheel 101, an output 103, the first a comparison unit 105, a second comparison unit 107, and a load component, the input terminal 1() is connected to the input Vccl '. The output terminal 1G3 is the same as the client TV (10), and the first comparison unit 1〇5 has two first-input terminals. And the first input terminal 1 has one first input end having a first reference potential Vbl, and the second comparison unit 107 has two second input ends and a second output end D2, wherein one of the second input ends has a second reference potential Vb2. The potential connected to the other second input terminal and the other first input terminal is a divided piezoelectric position Vd', wherein the divided piezoelectric position" is compared with the first reference potential vw to generate a first output potential at the first output k D1 Comparing the divided piezoelectric position μ with the second reference potential Vb2, the second output potential is generated at the second output terminal D2, and the voltage between the peak potential Vd and the input terminal ιοί and the divided piezoelectric position... and the output terminal 1〇3 At least one of the connections is connected to at least the load element 109, or may be referred to between the divided piezoelectric position Vd and the input terminal 101 and between the divided piezoelectric position % and the output known > Each of the load elements 1 〇 9 is provided. The input voltage Vccl is at least higher than the second reference potential 2, and the second base 5 M435789 [main component symbol description] 10 hacking detection unit 30 control unit .50 signal output control unit 60 voltage dividing device 101 input terminal 103 output terminal 105 first comparing unit 107 second comparing unit 109 load element® 601 detecting element 603 splitter Vccl input voltage Vd divided piezoelectric position Vbl first reference potential Vb2 second reference potential LTV User TV NLTV non-user side Depending on the video signal S
