Question about Signals

    Is there any limit to the amount of DVBT or Saorviews signals you can have in your house?
    Im getting the tv guy around soon , and I am asking him to put the free to air signals into the four bedrooms and also the Irish signals.

    Also in two of the rooms I might be using a PVR for DVB-T so should I get him to put two signals into the rooms where I will be using a pvr recorder or can they be easily split by some gadget? Also getting him to put the wires inside the walls ,because they are currently running down the walls like snakes in the rooms where there are signals.

    The main room at the moment has a Freetoair box and signal and I have a satellite outside.

    A DVB-T PVR only needs one signal feed. Satellite PVR only works fully with two.
    . . . or can they be easily split by some gadget? Also getting him to put the wires inside the walls ,because they are currently running down the walls like snakes in the rooms where there are signals.

    In that case, he should install enough cables to avoid having to use a satellite/terrestrial diplexer.
    You'll also need at least a quad LNB for your dish.
    How many rooms in total do you intend feeding?

    Thanks, When I said DVB-T I meant the FTA satellitte feed. Just googled it and I think the term I should have used was DVB-S. So I guess I need two signals in the one room for a pvr.
    Well in total ,I want the four bedrooms done, the sitting room already has a feed.
    One of the bedrooms will require two feeds and I want a extra feed in the sitting room.
    So that will be seven fta satellite feeds over five rooms. Hes calling tomorrow to have a look at the job.

    Well hopefully he'll know what he's doing.
    It's no harm to install 2 sat. & 1 terr. cable to each room (or at least leave room to pull them in) in case you want to add more services in future. Maybe network cable too.

    Four twisted pairs of wire in a common cable, that might be screened. Cat5e is the the normal spec.

    Used for Ethernet from 10Mbps to 1000MBps (1Gbps).

    can also be used for HDMI (two screened cables), VGA (via balun), SCART (1 or 2 and Baluns depending on if RGB or composite), phone or DSL modem wiring, microphones, sound in or out, remote control.

    I have an internet tv in the sitting room but it requires a sony dongle which is expensive or I need the network cable, but seems a bit much to have the cable running all that way just for the tv.

    One more thing In one of the rooms which already has a saorview signal ,i use a spliiter , this one : http://www.argos.ie/static/Product/partNumber/5346147/Trail/searchtext%3EPHILEX.htm

    because I have one of the signals going into the computer tv card and one into the tv, should I get a proper second signal down or should I just continue using the splitter, there seems to be a good few glitches at the moment, would the splitter be affecting the signal quality?

    Explain the situation to the installer & he should ensure the distributed signal is good enough to supply two devices either by providing a single cable that can be split reliably or running two from the distribution amp.
    You can also use amps within the room to boost split signals if needs be.
