Does anyone know of a relatively ready-to-use solution for sending serial data over an existing SD video stream? Maybe during the vblank section of each frame?
I'm hoping there might be an existing solution that would let me stream in serial data, encode it into the video, which would be transmitted and received, and then decoded out of the video, and sent to a microcontroller as serial data.
Or maybe I'll just have to bite the bullet and add another radio system on yet another frequency...
Thanks for any ideas!
