Did anyone ever write a TBC filter in software? It might be a bit dependent on picture content, but it strikes me it ought to be possible to do something that would match up the horizontal position of rows of pixels by minimising contrast between adjacent lines..
I don't know of one, but that doesn't mean too much. I do remember a discussion a few years ago with some math/video people about using FFT-based frequency analysis to detect horizontal shifting, so it ought to be possible; beyond my math skills.
