ELI5: How far into space can we go before video or voice transmission would cease?

Even if the home base would not be on earth, what is the distance, if there is any, that would stop communication.

No distance would be too far.  The only limit is the lifespan of the people trying to talk to each other.  All forms of light travel at the speed of light.  This includes radio waves, which is how you might communicate.  If you broadcast such a signal, it will travel out into space forever and ever.  However, if you're trying to talk to someone who is 1 lightyear away, it will take one year for the message to arrive.  And a further year for their message to make it back to you.

Move the speakers further apart, and it takes even longer.  Imagine asking a question, and then telling your descendants to wait around for the answer.
