For FPV/OSD, it seems as if the 2 options for viewing are using a monitor or goggles. Both use A/V and RCA cabling it appears, so does that mean that most (all?) FPV/OSD is analog? Does anyone know if it is possible to use a typical tablet, rather than monitor? Is it possible to get an adapter that takes the A/V signal from the RCA plugs and converts it to a digital signal via a USB plug. Is that the stumbling block, i.e. that FPV/OSD is analog and tablets are digital?
Or am I talking apples and oranges?

There have been some success getting this to work with Google Nexus tablets. A Russian forum user was able to convert his Nexus tablet into a rear view car monitor using EasyCap. It required a custom firmware for the tablet and a custom built driver for EasyCap. I spent quite a few hours trying to get it to work with my cheap Chinese made tablet, but the hardware was just different enough that I couldn't get it to work.
One thing to keep in mind is the brightness of tablets. I wouldn't want to use mine as a primary FPV monitor.
using a android tablet with USB OTG, and a video capture device, you could display the captured video.
those devices cost very little on ebay, but I doubt the drivers are in the kernel, so whoever would program such cool app, would need to get driver from manufacturer or linux kernel.
