It seems that it’s possible to do OSD without the LM1881, and a fairly simple circuit. Granted this does not have the syncing ability, but if one was just wanting simple OSD would this be a feasible alternative to the LM1881 setup?
The reason I am asking, is because I am wanting an easy / cheap way to do the black background behind the text. The text on a white background is hard/impossible to read. So upon researching I found the forum post above.
There is now a LM1881 version of this OSD however the Pin usage is different than what is used in the Video Experimenter. There are many of these board out there, some sold by flytron.com. Personally, I see an opportunity to breath some new life into the LM1881 OSD with the usage of this Arduino-TVOUT providing some bright and talent person would take up the challenge. 😉
