Diplexer - Wikipedia, the free encyclopedia

Im using fios internet. Would it be as simple as hooking one diplexer up where the fios box feeds to the main coaxial line and then another one where the tv is (which also happens to be the same place where the modem is)? If i have coaxial cable going to multiple rooms in the house would complicate anything, or would i just need to split the single going out to additional rooms? It just seems real confusing to me.
