    I've been watching Freeview hooked up to my PJ and the compression on the channels somtimes is terrible, the pictures are clear but when you see the banding with skin tones up close etc. it looks really pixelly and you lose the feeling of watching a big tv (and it looks the same on my tv also - just alot smaller).

    I'm using a Nokia 9850T ondig box and was thinking of switching over to sky and want to know if sky has the same problem's with its bbc/itv channels and to what extent the premium channels are affected eg. Sky One/E4/Paramount/Premier etc.

    Cheers

    In my experience, Freeview was abyssmal. Sky is (mostly) transparent to artifacts anywhere near as bad. They are there though.

    I use sky and a stb for freeview and I find the picture is usually equally as bad - on certain channels -with both systems. Blocky lego look ect, if you know what I mean.

    When its really bad I usually go back to watching analogue. In fact my BBC 1 analogue reception is usually excellent so I don't bother watching it on digital anyway.

    I'm not sure if the platform makes much difference.

    It's the source material and carriage that counts in terms of quality...

    Have watched a few movies on the BBC channels on Freeview and have almost been fooled into thinking I was watching a DVD on occasions (e.g. the broadcast of Out of Sight was superb).

    I wonder why it seems to vary so much, we were watching Jonathan Creek last saturday night and it was quite pixelly in places, mostly where mpeg2 has real problems skin tone, dark areas etc.

    Would certainly like to know if it can be improved in anyway, do the newer ondig/sky box's do this better??

    Well SG and me both have DTVAs and reckon they are excellent but not quite up to Sony IDTV tuner modules for sheer picture quality

    @ Martin

    You seem to always rave about how good the sony is...

    but have you seen pictures from the Philips DW 6557

    I have one and it's absolutely fantastic, clear and sharp

    anyone considering a iDTV should get the Philips DW 6557

    Haven't seen any Philips IDTVs but I have seen Pixel Plus and thought it was yuck - very pixelly!

    I have had 3 TVs in my life all still work all are Sony, I like the Trinitron tube, and Wega were the first flat tube TVs.

    But liking the TV is the most essential thing:)

    But I do like anamorphic RGB pictures! (RGB inside TV)

    IDTVs seem to be getting better, mine had the picture quality but text is not that quick.

    It is good that people can buy one now with confidence.

    Which tube in the DW6557?

    I think it has the LG Phillips tube (no dots on the side)

    Text is also a bit on the slow side on the Philips as well, but i dont mind especially when the picture is SO good !!

    DVB-T Tuner is connected via RGB rather than PAL composite

    Thanks very much for your help Martin I appreciate it!

    I may appear dumb, but I have a further question! You mention anamorphic RGB pictures. Is this something different from a widescreen picture ie something only provided by a digital tuiner ?

    Digital Tuners output a proper widescreen picture for 16x9 TVs

    I would never buy a PAL only 16x9 TV.

    BBC 1,2,3,4,News24
    ITV 1,2
    C4,C5

    All in 16x9:smashin:

    ***********

    By PAL only set do you mean a non IDTV?

    Is there a then difference then between viewing a prog using the digital tuner in a IDTV and viewing using aRBG skartconnection between an extenal digibox and a similar but non integrated set ? If so could you explain why .Thanks for your help

    I have both sky and freeview and find picture quality much better on
    freeview.Its obvious to see that most channels are running higher bit
    rates on freeview.ITV1 and ITV2 are amongst the best looking channels
    on freeview with BBC THREE not far behind .

    Only SKY NEWS and CHANNEL FIVE look better on the sky digital platform and
    do seem to be running higher bit rates on sky than freeview and look amongst the best sky has to offer along with its sky sports channels.

    Presumably, unless one has the circuit diagram of a particular set ,there's no way of knowing whether the signal within an IDTV is transferred between the digital tuner circiut and the next stage as RGB or a better way such as chrominance and lumimance or even component signal which, of course I suppose could be the case ---Do you have any inside(sorry!) knowledge about this??
