The lightest video-capable satellite terminal that I, a mere civilian, know of weighs around 3kg. Even as a satellite equipment, it's relatively expensive to buy and operate. Its power requirements are also non-trivial, both because of the need for highly compressed video and the high-power radio transmission. I think you can do the math from there.
