    Hi,

    I am currently planning out a Home Cinema and I am current looking at the cabling side.


    Do Scalers/processors perform a conversion switching function? So that you only need to run one cable (say DVI) to a Projector.

    Or do you need to running a cable for each source component?

    Cheers

    Yes you would only need to run one cable from the scaler to your display - as well as scale / covert or whatever it'll also switch. I run a single lead from my scaler to the plasma. Now all I gotta do is bury that cable in the wall... ;)

    Hi Dan,

    Thanks for the reply. Do you have an recommendations as I have no experience of scalers/processors and need a nudge in the right direction.



    Cheers

    Hiya, I bought an iScan HD to sit between my sources and my screen and while I am very (*very*) happy with it I cannot really advise "buy X not Y" because I have no experience of any others in operation! In the same way that all "what plasma should I buy?" threads turn into an "I bought a X and I love it" vs "I bought a Y" posting competition, I'll start by saying the iScan made my NTL Digital box's pictures watchable on my 50 incher, because when sent straight to the screen I could've cried! And on top of that it is (relatively) cheap. Next month Gordon's coming round to ISF me, when that's done the source -> scaler -> screen will arguably look as good as it is ever gonna look so I'll be in a better position to judge just how fab it all is. I'll get back to you!

    Dan.

    Thanks for that, Dan.

    Is the ISF calibration expensive?


    Cheers

    When looked at in terms of the number of DVDs or pints of beer I could buy instead - yes it is, very! But since I've already spent nigh-on six grand on a plasma + scaler + DVD player + my monthly sub to NTL, I consider it worth the cost to make sure I'm definitely getting the max out of the money I've already spent. I ummed and ahhed for a long while about getting it done - if you do a search for "ISF plasma" you'll find all the same posts I did which eventually convinced me to go for it!

    Most Video Processors do act as video switchers and will accept a range of varied Input signals and bring them all together as one output signal.

    If your planning a Home Theatre the 'big' question is if your sticking to a single display device (plasma) or possibly two display devices (plasma + projector).

    Many Video Processors can potentially have Two output memories set up to enable you to have different settings to suit multiple displays - though mostly the Video Processors only have a single output so you may need to add a Digital (DVI or HDMI) or Analogue (RGBHV or YUV) Video distribution amp 'down stream' of the Video Processor.

    Its also not unheard of to have a third display device to 'preview' your video sources if you have the kit in a separate room or a cupboard - where you cant actually see you main display; a small LCD PC monitor is often used.

    You also need to plan carefully if you want to be able to record any video sources to DVD, VCR or PC - your not likely to find a recorder that works with the scaled output from the Video Processor so you have to send the 'un processed' source signal to a Recorder plus the Video Processor.

    Any questions please shout.

    Hi Joe,

    I will be sticking to a single display device, a projector (not decided which one yet).

    I think mine will be a fairly simple set-up:


    DVD
    SkyPlus
    X box
    Playstation2

    all connected to the scaler.

    Have you any recommendations to get me started?


    Cheers

    Gary
