LV2 Video Overlay System
We chose to use:
- Decade Engineering (in OR): http://www.decadenet.com/ - BOB II = $79.95
Because of it's small size. Note that it just uses a simple ST part which we can integrate into the ATV node for the next generation design.
Here's a video capture of the overlay
Overlay Text Specification
The BOB-II gives us 28 columns by 11 rows. We'd like to display the FC status and GPS information. Here's a first cut at what we'd like to display:
