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. ------------------------------------------------------------------------- Kyler Laird I'm the NRA ky@en.ecn.purdue.edu
