What is the signal format of the data coming out of a usb webcam? Is there a signal for the beginning of a new 'frame' or something like that ? How do I get a 'snap shot' from the data?

The web cam has software that takes either video or single frame
pictures at different resolutions.

I want to mount a cam in a model airplane and transmit a frame at whatever resolution requires the least amount of initialisation (probably just the power up default for the web cam) and transmit it a frame at a time to the ground station receiver (to be processed by my own written software), as soon as one frame has been transmitted I will wait for the start of the next one? Can I do this ?

I think that half of the intelligence of a web cam is in the device
driver in the computer. I think a cctv type camera is easier to get
output from. Essentially the camera chip gives a standard video
signal that can go to the transmittter. There are wireless
cameras for home surveillance systems about the size of a golf
ball.

Ok I will look into a cctv camera. I hope it is not too expensive or limited on signal power. In the mean time do you know what the data format is from the web cam of am I going to have to get my oscilloscope out ?
