I'd like to experiment with creating some TV accessories. They would require
digitized video. I was flipping through an '88 Newark catalog and noticed that
TI makes/made a 40/50MHz video processor chip and support chips for color
operation. I don't know what the limitations are with the complete setup.
Questions:
1) What are the requirements for a decent picture? Isn't the vertical res.
~350 lines? What's an acceptable horiz.? How many colors?
2) Are there chips/chip sets available to do this job? My girlfriend's VCR
has a digital still frame that seems to be based on essentially what I'm
looking for.
3) What is the difference between DRAM and VRAM?
E-Mail or posting fine; I think it's an interesting topic so I'll post a summary
of E-mail responses.
