| Splitting rca signals, audio and video? what would happen if i split the rca video and audio output from say a playstation to two tv sets? do i need a booster or will it be ok to a certain length of cable? will it damage the tv? will it damage/stress the playstation? |

| Why would you do that??? |

| Battleships? :p apparently the impedances need to be alike. |

| I pretty sure you can buy a splitter from DSE 1 into 2 etc. much easier than doing it yourself :P |

| Couldn't you justhook the second TV into the output jacks from the first? |

| Well actually i just used the playstation as an example. i dont actually own a playstation lol but yeah battleships is what i thought about too lol. im hooking up two tvs in two rooms over cat5 it seems to working well. its so the missus can watch tv shows and not have to use the bunny ears. |

| Wouldn't that mean that she has no control over the channels I'm guessing you're trying to run connections from a Sky or Freeview box?? |

| Save Time And Energy Get her some BUNNY-Ears! :) Or split the aerial cable :D |

| What happened to the rest of the Bunny costume ?... |

| It works with audio (it's not technically the correct thing to do but who cares), but I don't know about video. You won't damage anything by trying. You can buy distribution amplifiers that do both audio and video. |

| There was a thread on TmTech about using ethernet cables to transfer video and audio through a house. Month or 2 ago but im sure it will be somewhere at the top. Maybe it was you who created it? |

| ==I port sky to the main school staff room from the server room along cat5 but i am using the proper converters. Distance about 150m as the cable goes. |

| As you have seen picture goes darker - because now you have split the video signal there is 50% of the power going to each monitor/TV. Video is nominally a 1 volt peak to peak signal. Variations in voltage level control the luminance (brightness) of the picture. You have chopped the max brightness level in half and hence have low luminance so picture is darker. What you may or may not notice is that since you have reduced all video information by 50%, there is now less dynamic range for the luminance signal and so you might notice less granularity in brightness variations i.e pic might go from full light to quite dark with not much variation in-between. Sync pulse and Colour sub-carrier is also reduced but likely that presents no issues for a TV - But it will for a video recording device. |

| And as some here have said Audio 'should' be ok. This is because most broadcast audio sources are a low impedance source. This gives them the ability to line drive into a range of audio receiver impedances. If you halve the effective audio receiver impedance by commoning two receiver ports together it shouldn't matter much, as half of two high impedance receiver ports is still a relatively high impedance. This is what I think from what training I've had many moons ago. Could be wrong... |

| Mark, you are rather on to it Interesting stuff you know... |
| geek_seriouslycgi | August 28, 2008, 9:59 pm | #21 |
| Thanks mark so far so good, its running thru cat5 to two rooms both show a good picture. the only difference is the darkness when both are plugged in even if only one is runningits been real cheap to set up im just worried about damaging something, i have no backup lol ive hardly had to do anything. basically i chopped a patch cable and soldered it to rca plugs (split) then chopped another patch cable and soldered rca's to either end which go to the tv. thats it.. |
