Yes! Digital wireless video systems is relative high cost and of cause over budget for most people, but the technology is getting closer to what we can reach in our UAV projects. Lets hope these systems will reach prices we all can handle.
Here is a system who fits perfect in a small UAV.
Receiver case is even made with small 7" TFT screen in a nice strong Case.

Comments
Of course, one could (using up a bit of payload weight) simply strap a USB 4G modem, a USB travel router with 100Mbit ethernet, and any one of hundreds of embedded ARM boards with ethernet on them. Payload weight? Probably about one kilogram at this stage, including short runs of cables. Everything runs on +5VDC. With the embedded ARM board, get yourself one with a USB slave port (so this leaves out the useless RaspberryPi) so you can connect to a PhoneDrone through Linux-ADK drivers - if there is interest, I'll fish the link out of my bookmarks. Also with the embedded board, you can simply connect thermal cameras (I know of one on Kickstarter that uses Bluetooth and a thermopile array) and other odds and ends, streaming the data back to the ground, and even allowing the ground station to also be portable, on the 4G network.
Just to bump this forward, here's a great product from my buddy Zoltan at NGH.
