Description of the invention (1) The present invention relates to a kind of electric face dongbo: W Jin Jin Er ^ + co-broadcasting method for locking the image screen of the people and the standard video signal and timing of the device. Displayed on Rongmu: Fang Press, now the TV image is displayed on the Lei Nai Kai TV box), only the TV tuner: TV 5 converter (commonly known as the signal sent directly to the conversion circuit "22 = R) The input signal does not meet the expected standard 'or the image signal loses the same 2 and the standard image cannot be rendered. Make the computer screen appear chaotic images, which is the main method of locking the picture and its device of the present invention # When providing a television box image signal, it will be repaired so that == non-standard image timing is obtained. Clearly displayed on the computer screen. 〇Indication of the image signal and the method described on January 1 'is to send the silk into the mountain and then send it out in the form of a pulse signal. The continuous image time point, * The method described, = Control :: = Judgment = fixed value' makes the micro-control The device calculates = set to a certain fixed but less than = period 'approximately i / rate or increase the signal level for: electrical inversion or removal of fixed point frequency The aforementioned method is selected by Jiang Zhizhi. Discontinuous circuit, used to filter out the image signal after the level is added. 俨 = In addition to the fixed point frequency or increase the signal, the aforementioned devices are included to form any discontinuous image time point of the standard image signal. Page 5 5. Description of the invention (2) The aforementioned signal of the numbering level, etc. The aforementioned signal of the synchronous image of the present invention is described in detail in the embodiment of the invention. Contains a synchronization signal in addition to the fixed point frequency number correction circuit rate and increase the letter for the main special picture system second picture system third circle system fourth picture system fifth picture system sixth picture system seventh picture system Explanation of the drawing number of the eighth perimeter system: 1 1 · Image is not 1 4 3 · Signal 1 4 1 · Signal 1 3 · Please refer to the above for synchronization), it is based on the picture, so it is mainly filtered as shown in Figure 1. The present invention, the present invention, the present invention, the present invention, the present invention continuously detects and buffers the electrical reverse electric signal to produce a picture, sequential scan, discontinuity points shown by lines and two and its, and more like a signal circuit program image The removal of the signal, the synchronization of the image, and the novelty of the waveform block diagram flow (discontinuous inversion electrical fixed point signal slow signal repair) will be matched with the following drawings, as shown in the figure: Figure. The test circuit ^ 1 2 ^ 15 generator 14 2 general image signal method from the point scan into the line between the line, is based on the image time point detection circuit circle diagram.
