Help coming up with Anti-BLUESCREEN device

I don't quite understand the attitude everyone has on this forum... I fully realize that if the original video gets corrupted to the point of static that the data is gone, but at the same time every older tv can show static, as well as many other devices such as my dvd player, there are also other devices such as various dvrs capable of outputting the video feed static and all. There was someone else who used lm1881 to detect loss of sync then use the arduino to generate them back plus a resistor to lower the noise below the sync signal. There must be a chip that can process the video and output it back which is why I asked in here... Everyone on this forum likes to point out skill levels which is the entire point of a forum like this, to expand upon ones knowledge and share it with others. If a $10 device can do it there is no reason it cannot be produced diy style.
