    Hello everyone......first post in this forum.
    I now have what I regard as an excellent HC system.
    I currently have:
    Denon 3805.
    Pioneer DV656A-K component and coax to Denon.
    Sky+ JS RGB-YUV and optical to Denon.
    Component from Denon to PDP50MXE-1.
    I am looking at various options for my next addition/upgrade.
    One of these options is improving picture quality with a scaler or other device.
    I have had no experience with scalers, and I would like to know what your recommendations or suggestions are.
    I am fully aware of the HD issues regarding my display, but I would like your suggestions based on current and future compatibility.
    Thanks everyone.

    Johnny.

    Well the Lumagen Vision HDP looks pretty great on my 8" CRT with a 7' 16:9 screen :) It has a few operational bugs but nothing serious. The PQ on the other hand is outstanding and free software updates come out regularly meaning that it just keeps getting better :) It has DVI ins and outs as well as component, RGsB, RGBS, RGBHV, S-vid and composite. At the moment they are working on a 10 bit pathway for the processing which should produce some great results :thumbsup:

    So what will a scaler do for my Sky+ picture quality, and my DVD picture quality.
    Will a scaler show my DVD player up as an older piece of equipment and bring on an upgrade there too.
    Thanks.

    Johnny.

    A scaler will in general improve the picture quality. What is the resolution of your screen? The Lumagen is very flexible and will allow you to pixel match your display giving you the sharpest possible image :thumbsup: If you were then to get your system ISF callibrated it wil look the muts nuts! :smashin:

    From another post today, I now know that my Sky outputs at 576i.
    From what I am reading about Lumagen products, they only accept at 1080i.
    Am I misunderstanding something....?
    Also, does running Sky+ through a JS rgb-yuv affect anything.
    thanks.

    Johnny.

    The Lumagen will take just about anything, and is just about the most flexible scaler about for the money. I feed mine with 576i PAL / 480i NTSC from my DVD player and 576i from my x-box and Freeview box. It outputs a 720p signal for NTSC and a 768p signal for PAL, frequency matched to source of course :) You can dial in the output resolution that best matches your display device and have seperate settings for all sources :thumbsup: It will output anything from 480p up to 1080p :smashin:

    Thunder, could you please explain what this will do for Sky+.
    Will it sort out the pitch issue on football...?
    Also, what else do I get if I push it to the HDP Pro....
    Cheers.

    Johnny.

    The general opinion is that scaling seems to make Sky better, if not perfect :) "you cant make a silk purse from a sows ear" as they say. The best way to make a real improvement to Sky would be to get your box SDI modified to take the signal straight off the MPEG decoder and then into the Lumagen. For a more informed opinion on the effect a Lumagen would have on Sky it might be worth PM'ing Gordon as he's the distributor over here and knows them inside out :) The HDP gets you the ability to scale HDTV signals such as 720p etc up to 1080p (which will be usefull when HDTV/HDDVD turn up. It also has a much better upgrade path, this will be especially apparent when they implement the 10bit pathway. at the moment they use the popular SIL504 chip set for deinterlacing as used in the I scan products and many DVD players, but this only allows 8 bit resolution. They actually plan to bypass the SIL504 in a later firmware release using their own 10 bit deinterlacing algorythm. This gives you some idea of the flexibility of this machine :)

    A few more questions then.......... :)
    I have read up on all the threads regarding SDI,HDMI etc, but, will SDI defeat the need to prepare for HDCP, or will manufacturers find a way to block SDI mods already carried out.
    Am I better to wait until the HDMI issues are sorted out with the Lumagens, or
    is DVI just as good.................... :confused:
    Thanks for all your help Thunder.

    Johnny.

    According to Jim at Lumagen pressure is being applied to stop players being produced which can be SDI modded, and he certainly never expects to see an HD player capable of being modded. HDMI is definitely the future, though DVI+HDCP is viable a short-term solution.

    OK, one final question.
    Do you all recommend that I look towards HDMI.
    Do I go for a SDI scaler........... :confused:
    Or something in between all three.

    The DVI inputs on the Lumagen will take a HDCP encrypted HDMI signal with the appropriate adaptor cable :)

    So could you tell me what, in my situation, would the HDP Pro give me
    over the HDP.

    Cheers.

    Hello Johnny

    Just a quick recap - the Lumagen Vision range will work with DVI, DVI with HDCP, HDMI and SDI Inputs (the VisionDVI and HDP require an Optional SDI card).

    If the Input signal has HDCP applied so will the Processed Output signal - though there are now little 'black' boxes that may be the saving grace for all those with non HDCP DVI inputs on Displays and Projectors.

    Lumagen now have HDMI equipped Pioneer and Arcam players acting as 'Digital' transports - with the Players outputting 480i and 576i via HDMI to the DVI Input on the Vision Processor; very close to SDI without the requirement for modification kits.

    Going with the Pro over the HDP adds a few extra features - such as a front panel display and the potential for improved performance due to some of the design elements of boards and internal layout; the HDP will work well with your MXE1 and the Pro will add a bit of extra polish to the system.

    Whichever unit you go with we always recommend a install, configuration and ISF Calibration is included in the overall budget if you want to ensure you get the best out of your system.

    Best regards

    Joe

    PS And you get a full compliment of Input cables bundled with the Pro!!!

    Thank you for that Joe.
    Does this device bring lipsync problems into the equation.
    Thanks.

    Johnny.
