eli5: In a world of instant communication via satellite, why does news anchors connecting with field reporters live still involve a 3 second silent pause?
In: Physics
Hey, I did my thesis on something relevant!
Basically if you go the satellite way then the signal.has to travel all the way to the satellite and then be relayed all the way back to earth. This process alone takes almost half a second.
The instant communications we are used to usually are communication where the signal doesn’t have to leave the earth. For example the cellular networks that our phones use.
There is the option for news agencies to go this way, but sending a high definition video and with enough frames to look good on those big TVs we have demands a lot more data than an average video call does and ends up being quite costly.
