Which is better: Faroudja DCDi (DVD) or Pioneer Pure Cinema (Plasma) Deinterlacing?

[McKinley]

Having recently bought a 42" Pioneer plasma, I'm interested to see if the picture quality of my Pioneer DV585 currently connected via component can be improved upon. The Pure Cinema deinterlacing of the plasma is fantastic, removing all traces of 3:2 pulldown that I could see. Note: This is a different (better) version of Pure Cinema than found in the Pioneer DV696 etc.

I have a budget of around £250.

I was considering getting an Oppo 981 as this seemed the most likely to offer picture improvements over my 585 at this price level. HOWEVER, the 981 does not allow 480i/576i output via HDMI, which means that I couldn't use the Pure Cinema deinterlacing in the plasma if I wanted to. It does have Faroudja DCDi though.

Please can anyone tell me:

1. How Faroujda DCDi and Pioneer Pure Cinema (plasma) compare as deinterlacing solutions?

2. Is Pure Cinema (plasma) good for 2:2 deinterlacing?

3. Does Faroudja have the macroblocking bug on 480p/576p resolutions?

4. If there's no real difference between the two solutions, what are the best players for use as a transport (i.e. outputting 480i/576i over HDMI). I'm only aware of the Oppo 970 or the Pioneer 696 both of which use a mediatek mpeg decoder. Are there any better options at this price level?

Thanks

hey I too am curious to see responces on this thread, I am a very happy Pio DV-575 owner. Personaly I wouldnt buy anything DVD player that has a faroudja chip in it, read far too many posts etc about macro-blocking problems with them. I was looking at the Denon DVD-1930 but wont buy one because of this. Im hanging on for the next gen of Pioneer players myself

I have a 696 and a 427, pure cinema is switched off on the plasma, (and will always be). For my money, the dvd picture output at 720p is fantastic, very difficult to criticise it at all. I'm no dvd geek, so I have no idea what 3:2 pulldown is, but I get one hell of a good picture!

3:2 pulldown is motion judder introduced into NTSC movies as result of converting the 24 frame film to 60 frames (frames are repeated).

The plasma features a deinterlacing system that can eliminate this by combining it with a 72hz refresh rate. The Pioneer 696 cannot do this.
Outputting 720p means that the deinterlacer in the plasma is bypassed, and the one in the DVD player (not as good) gets used instead.

My DV585 (which is basically the 696 without HDMI) looks worse when outputting progressive into the plasma than if I output interlaced into the plasma and switch on pure cinema.

The pure cinema badge on the DVD player is misleading as it is not the same technology as in the plasma.

They are both impressive solutions for deinterlacing but have different strengths and weaknesses.

Not really spent a huge amount of time with it.

MB is at all resolution and is a 'chip' thing, however with proper calibration it is not really an issue here with Oppos. Other players, it has been.

Not that I have found. Given your budget however I think I would buy a 981 as a proven performer unless you can get you plasma to regenerate a 48Hz signal from a 480i input.

Thanks Nic.
I don't really understand your last answer I'm afraid.

I thought the plasma (when set to 75hz mode and pure cinema) will take an incoming interlaced ntsc 60hz/pal 50hz signal and inverse telecine it to a multiple of the refresh rate (I realise that ntsc would be 24*3=72hz, rather than 75hz). Is this not the case? - I thought this was why Pure Cinema ntsc was so smooth.

Why would I need to regenerate a 48hz signal?

The DV-585 is not 696 without HDMI. The DV-585 uses the MediaTek 1389EE, just as the DV-575, whereas the DV-696 is based on the newer and improved Mediatek MT1389EXE and includes an additional MT1392E HDMI upscaler. See http://pioneerfaq.info for more detailed information.

I'm aware that the 696 includes an upscaling chip. However, can you tell me what the difference is in MPEG decoding performance between the MT1389EE and MT1389EXE? I'm not interested in upscaling via the player - my plasma will still have to scale 720p to 768p and it will not be as good.

I am also curious as to the difference between the Mediatek MT1389EE and MT1389EXE chips. If anyone knows it'l sure be appreciated?

I don't have a Pioneer here but as far as I am concerned whether it displays at 48 or 72 is irrelevant, they are essentiall the same thing as far as what we are talking about here but I know this is not always possible to do this on all progressive signals hence the comments above.

One important difference is that the MT1389EXE is the first MTK chip that deinterlaces PAL content correctly (the MT1389EE in the DV-470/575/585 and the MT1389FE in the DV-490 could not do this, for a description of the problem in the DV-490, see http://www.dvdtimes.co.uk/content.php?contentid=61831). In addition to this, the MT1389EXE is DivX Ultra certified, while the MT1389EE and MT1389FE are only DivX Home Theater certified. This last suggests that the MT1389EXE has more raw processing power than its predecessors and should perform better in more demanding situations.

Visually, I cannot find much difference between the MT1389EE-based DV-470 and the MT1389EXE-based DV-696 (I have both) when connected over component at 480p/576p, but then I do not have the PAL DVDs mentioned in http://www.dvdtimes.co.uk/content.php?contentid=61831 for which the PAL deinterlacing of the DV-490 has been observed to be particularly bad. HDMI at 480p/576p is very similar to component (I have the DV-696 connected to a Sony 32v2500). However, HDMI at 720p provides a very noticeable improvement, especially on lower-quaility material which the DV-696 seems to upscale and clean up much better than the Sony. The difference between the DV-470 and DV-696 on DivX is literally night and day.

Hi Peri thx for your input! I have read that link on the DV-490 before, althought I did wonder if that particular model was designed specificly for NTSC because if you notice in the players menu you have options for 720 x 480i and 720 x 480p.

480 is the horizontal resolution of NTSC PAL is 576 so I wondered why in the players menu there was no option for 720 x 576? This makes me wonder if the player reviewed was designed just for NTSC?

This is from the first page of Lyris's review of the DV-490, the DV-696 behaves identically:

(Note that the resolution option in the player's menu changes to reflect the last disc you had in - 480 for NTSC, 576 for PAL.)

ahh right I see the player "see's" the resolution of the disk, I understand. So I understand that the DV-490 then uses the 1389EE chip and therfore cannot deinterlace PAL correctly but the DV-696 has the new 1389EXE which can? Is that about the sum of it?

On the surface, yes. Finer differences between the MT1389EE/FE and the EXE would be more difficult to quantify, apart from the pronounced improvement in DivX decoding. One interesting observation is that in the States the DV-696 is marketed as one of the 'premium' Pioneer DVD players, Pioneer Elite DV-46AV, the first of the Elite series to carry a MTK chip.

By the way, the highly regarded Oppo 971H uses MT1389FE for MPEG decoding (see the pictures in http://www.avsforum.com/avs-vb/showt...9&page=6&pp=30), and I assume that the newer 981HD that many people are raving about is based on the same chip. So, the 'budget' Pioneer DV-696 does seem to have an ace up its sleeve...
