Technical conceive of the present invention is, by the high speed logic device counting count information of paper money counter and Currency Type information are added on the dynamic video signal with the form of color character, and the two-path video signal carried out overlap-add procedure, promptly earlier one tunnel vision signal (client's appearance) is dwindled, show with another road vision signal (sales counter overview) stack again.
Technical scheme of the present invention is as follows:
The character video frequency superimposing technique, its feature may further comprise the steps:
Step 1: analog video signal 1 and analog video signal 2 are converted to digital video signal 3 and digital video signal 4 by video decoding chip.
Step 2: the counting count information of paper money counter and Currency Type information are added on the dynamic digital vision signal 3 with the form of color character.
Step 3: FIFO carries out sample process to digital video signal 4 by the control of high-speed programmable logical device, and sampled signals is merged into a frame with the digital video signal 3 of the paper money counter information that superposeed.
Step 4: the digital video signal 5 after will handling by video coding chip is converted to analog video signal 6.
Further comprising the steps of:
The viewing area of determining digital video signal 4 by the capable field sync signal and the Dot Clock signal of digital video signal 3;
The information of paper money counter output is given the conversion of character pattern generation module after giving processor processing by the RS485 bus transfer, character pattern signal after will changing is again delivered to the high speed logic device, and the high speed logic device is added to paper money counter information on the dynamic video signal in the mode of color character again.
Digital video signal 3 and digital video signal 4 can switch by the total line traffic control of RS485, promptly realize the function of changeable demonstration key frame and secondary picture.
Described high speed logic device can adopt CPLD, FPGA etc.
