Hi Kepvin,
By looking at your post i belive you have lot of GYAN in this thing. Could you pl help me in deciding some thing, i am planning to buy denon 1910 primarily becauce of its upscaling feature. Now, i have a samsung LED Tv with Dish Tv connection , do you think if i conect my TV through this AVR ,the PQ will be pushed to further good levels? and this upscaling is a sales man blah blah in all the show rooms where in we can only test the sound quality and no where this upscaling is demonstrated [though they pitch this feature very much].
Pl help me with this , if this upscaling is not of importance then i will be better off saving some money.......Thanks in advance.
Hi Deshu,
that's an answer that you'll eventually need to get for yourself.
PQ, like SQ, but even more so, is pretty subjective.. some people love overblown contrast and saturation, and dont care about black or white crush, some like smooth, soft picture, others like sharp pictures, and are willing to live with edge artifacts. so what works for one, may not work for the other.
haveing said that, there are some empirical guidelines.
1. All flat panel displays have some sort of scaler / video processor, since they display in only one (native) resolution, they need to process signals of all other resolutions and convert to the native resolution. quality of scalers vary and you'll have to judge what works for you, but general rule of thumb is that higher end tvs have better scalers / picture processors. I guess your LED TV is not a low end tv.
2. DTH PQ, (esp tata sky, which I have, cannot empircally comment on the others) is compromised because of low bit rates. Mpeg compression is lossy, as bitrates reduce, more and more picture information is thrown away, so even an high end processor cannot reconstruct a hi rez picture when so much info is gone. this is especially true of fast motion scenes, such as sports, action movies etc. if you watched the IPL final - then during the award ceremony, there was a scane when they were raining down ticker tape ont he winning team... that was multiple fast motion elements, and on my tata sky plus it appeared as a huge white noise haze...
The bigger point I am making is that dth PQ is flawed at source. You may be disappointed as progressively higher quality processing does not yield equivalently improved results. OTOH, if you want to scale dvds (much, much higher bitr rates than DTH) you will definitely see an improvement with better processing.
to sum.. don't expect magic from the denon processor, there is only so much improvement you can do to current DTH transmission unless they improve either bitrate or coding efficiency (mpeg2->mpeg4-> mpeg4 AVC) -> at best you'll just mask those artifacts that annoy you most ( which you can do using the picture controls on your TV)
anyway don't buy the AVR for PQ alone, reviews on this forum indicate best in class SQ for the 1910.
pm me for any further clarifications.
