As wal-dog2 said, that may be all you need to do. However, even though it's not rocket science (once the satellie is in the sky), your wiring may be slightly different.
Here's a link that has a few documents that will give you an idea as to how it's all connected.

Here's some things to consider:
What type of LNBF and/or Switch are you using to feed the receivers?
a. Maybe a DishPro Plus Twin LNBF to feed 2 satellites to 2 dual receivers, each receiver has a DP Separator to feed the 2 sat inputs.
b. Maybe a DishPro Plus 44 (DPP44) switch to receive 1-4 satellites at upto 4 dual tuner receivers, each receiver has a DP Separator to feed the 2 sat inputs.
With a DPP44 switch, there is a Power Inserter (power supply) that needs to go in a certain place, Port 1 after any diplexers, etc.... Remember this if you change or move cables.
You may be using or not using Diplexers (in pairs) which allows you to send the satellite signal down to the receiver, while using that same cable to send an RF signal, either in the same direction or opposite direction. If multiple cables are available, then diplexers are not needed.
When you remove the sat receiver from the bedroom, the bedroom TV will need to be adjusted/tuned/new channel scan/etc... to pick up TV2 and/or TV1 Outputs, since you removed the S-Video connector.
There's plenty of people here with advice. If later you need some help, just post with what equipment you are using, receivers, switch, separators, etc...
NOTE: Diplexers and Separators are
not splitters, but you may also have splitters to feed the RF outputs to multiple locations.
