Thank you.. Now I m getting outout, the font size is bigger though for a 21" tv. I wanted to ask this. If I construct the circuit diagram part of the MAX7456 as in datasheet except taking care of /HSYNC, LOS (output) and /VSYNC, and I apply an input CVBS through a camera (which has capability of connecting to tv), will I get a background picture from camera without changing any settings of the above program?? If not, what settings should I change ?? Please assist. Thank you.
