Video is transmitted via radio waves, and don’t need a “medium”. Earth is blasted by radio waves generated by all kinds of fun stuff in space like quasars and suns. Video encodes radio waves (similar to how a computer encodes electricity) and receivers decode and reassemble radio waves into audio and video.
Radio waves travel at roughly the speed of light, and therefore takes about 10 minutes to travel between Earth and Mars. Strangely if you google this question the answer supplied states 3-20 minutes, so perhaps electro magnetic interference may slow this signal? (Edit: I realized after posting that the variance is based on where Mars’ orbit is in relation to Earth... 3 minutes is possible considering this)
Sound is a vibration and thus requires a “medium” but vibrations and electromagnetics have nothing else in common.
Why is it impossible to send a video feed over a long distance?

Wouldn't where each 'planet' is in their 'orbit' affect the time?
