# Live feed from a Rocket traveling near the speed of light?

Okay, odd question popped up in my physics class today. If a rocket ship is traveling at .99c for 1 year, and is streaming a video at 30 frames/sec to earth, how would the earth feed be affected? Would it show the video at a much slower rate, would it remain constant, or would it be sped up?

Also, what if you added a time counter to the video feed? How would that change? I don't understand relativity that well, and this question is quite puzzling to me.

So let's say the rocket has a camera that's supposed to take a frame every $1/30$-th of a second. From the earth's point of view, this frequency will be reduced (by how much exactly is left for you as an exercise). Let's just for the sake of simplicity say that on earth it looks like the camera takes just one frame every (earth-)second.
Next comes the transmission of the stream back to earth. Let's say the rocket sends each frame individually in a single specially shaped pulse of light. Then in earth time, it sends out a frame every second. But during that second, it'll have flown another $.99c \cdot 1s$ further away from earth. Hence, the time between pulses is actually $1s + 0.99 = 1.99s$.
So instead of receiving 30 frames per second, earth only receives $1/1.99 \approx 0.5$ frames per seconds, or about 1 frame every 2 seconds.
