De-interlacers and upscalers can differ in quality, like how well they process moving diagonal lines, for example, but they can't manufacture added resolution that never existed in the first place.
IMO DVD players, and to a lesser extent AVRs, that upscale 480 to 1080i are more hype than anything else. True you have to upscale at some point to see it on your 1080p display, but I'd think generally a $3000 HDTV can do that better than a $100 DVD player.

Thank for your reply.
However, Horizontal Detail have nothing to do with De-Interlacing. De-Interlacing have relation with Vertical Detail. Ofcource As you know, Scaling have much to do with both Horizontal and Vertical Detail.
So, I think my problem is not caused by De-Interlacing process of SR876.
In my opinion, this is cause by improper setting of Low Pass Filter in the Video Decoder(in other words, Video A/D converter).
If I feed YPbPR 480p to SR876, the blur problem decrease(but still not good).
By the way,
What is truth is that - Both 480p and 480i have same Horizontal Detail !.
So, the H/W LPF in input circuitary can not be the reason of this problem(Since H/W gives same amount Filter Characteristic alwas~)
My guess is that, the Video Decoder(for A/D Conversion) for Analog Video Input of SR876 have different Low Pass Filter Parameter for 480i and 480p.
example : heavy LPF for 480i, and light LPF for 480p).
Anyway, I don't know Other User have this problem or not.
I would be gratful if someone gave me more advise and opinion.
And, if possible, Please let me know your own test result.















. I had in front of me a DTS "white paper" that plainly stated that the sample rate for MA was 96kHz. But of course it was an error. Other publications at the DTS have wording like this, "from source files with sample rates up to 96kHz and in stereo from source files with a sample rate of 192 kHz".
