Ask HN: Tips and resources for learning video DSP

I've been working on video DSP systems for a few months. I'm the sole engineer on a project that involves HDMI I/O on an FPGA using several memory buffers in internal memory and DDR3. All of this is self taught.

I spend a lot of time debugging video output. I have discovered a few rules that help pinpoint issues. A couple examples: -If data is early. This may be a FIFO overrun or a shortened data valid signal. -If the video is scrolling down or right, the data is late. This may be a starved FIFO or an extended data valid signal. -If the image looks stable, but has odd artifacts on edges, you may be sampling data on the wrong clock edge. Switch from rising to falling or vice versa.

Does anyone have similar video DSP debugging tips or resources (websites, books, forums, etc.) for this type of work?
