How to Use.........
- Before use, the circuit's jumper need to be set. Take a look at the table below:
MacroVision Type Upper Start Line Upper End Line Lower Start Line PAL 0x05 0x0F 0x126 NTSC 0x06 0x0E 0xF2. - To set the jumpers, first convert the line numbers to binary. You will end up with three binary digits, one for each set of line numbers. Bit 0 is least significant, bit 8 is most significant. Now simply open the jumpers at the 0 bits and close the jumpers at the 1 bits.
- Connect your video source to "Composite Video In". As the label suggests, this circuit accempts composite video signals only. The corrected video signal is sent to the "Composite Video Out" jack.
- With the two "Video" terminals disconnected the circuit passes video through without modifying it. Jumping the "Video" terminals enables the MacroVision removal.
- As with all circuits involving CMOS (4000 series) ICs, you must tie the unused inputs of those ICs to ground. This is not shown on the schematic for clarity.
- Supply voltage is 12V.
Try it and Enjoy.............
