Connect many TV together

Connect many TV together

Connect many TV together

(OP)
Hello,

I have a question, what do I need if I want to broadcast the channel on TVs at the same time & when I change one they all change like in a TV store.
What is the connection?
I mean are they all connected through a splitter to a DVD?
or how it works?
This is something I am asking out of curiosity,hope this is the right section

Thx

RE: Connect many TV together

In order to sell modern HD TVs, many stores have been forced to install expensive HDMI splitters to send the full bandwidth HD signals around the shop floor. In that sense, it's not a 'channel'.

In the old days (a couple of years ago), they'd just take the RF output (typically channel 4 in North America) and used amplified splitters to split the RF signal and send it around the shop floor.
