I intend to use a cheap FPGA, A HiSpeed USB PHY, and an Analog Devices Video A/D chip. I will nail down exact chip numbers later. The target platform driver and example code will be written for linux. This project is more a proof of concept and more for fun and excercise rather than to be practical. But I will take any advice and help that I can get and who knows what we might create here. Entire BOM should be less than $40 but we'll see. |
Yes I know about the Hauppage HD-PVR or whatever its called that Capures Component video at 720p. The problem is that device uses H.264 encoding, which is just way too expensive to decode, it takes a Dual Core 1GHz Machine at 99%. It is also not totally open to hacking. | Yes I know about the Hauppage HD-PVR or whatever its called that Capures Component video at 720p.
