Hello,


Do anyone have any comments on whether HTPC with dscaler or best progressive players does a better job on deinterlacing?


It seems that Dscaler can do 3:2 pulldown detect and 2:2 pulldown detect and as well as very cool deinterlacing alogrithms.


Any thoughts?

Different people will give you different answers.


It depends on what you're looking for: something easy to use, high picture quality, etc.


DScaler is not a replacement for the best progressive player. If you use DScaler, you're still going to need an external SDI player for the highest PQ. That SDI player is also progressive...

That's true. Ease of use is one important factor. But do you think dscaler does a better job than best progressive players in terms of deinterlacing. There must be some object tests that can decide once and for all.

No, personally I don't.


People use DScaler because it is a good way to integrade built-in DVD (Through TheaterTek, ATI DVD player, WinDVD or PowerDVD) and TV viewing or external DVD players.


DScaler in itself has a good film mode detection, but its video mode detection is only now starting to catch up to Silicon Image and Faroudja chip based deinterlacers.


An HTPC can become an excellent scaler. A good input board (like Holo3DGraph) can let you have a fantastic looking image if you have the right output card (Radeon), a strong computer and a good audio card.


A progressive DVD player outputs 480p, so scaling is done on the display (projector, plasma, etc.) which can detract from the image.


Still, this is not a fool proof way to create a video scaler. There are occasional frame losses (when memory runs out, or the OS has to get something urgently from the harddisk at the most suspenceful part of the movie). There are other problems like usability, lip sync delay, and a high maintenance compared with embedded solutions.


Overall, it's like comparing a dog with a carrot and asking which one changes a lightbulb better. The answer is :they're both different...

Are you using this on a system that accepts a VGA signal? I assume yes since you're asking about Dscaler. Dscaler is intended more for the scaling of external analog sources, not necessarily DVD. This is because if you have a computer to use dscaler, it's assumed you would use the same computer to play DVDs. A DVD rom drive can be had for 30 bucks easy, and computers are fast enough now that you can even do software video decoding and get excellent results on an HDTV, much better than any stand alone DVD player is capable of. If not, even an old 32MB ATI card is more than up to the job.


I'd say if you're not interested in using a computer to do DVD playback, it's not worth the trouble of setting up a computer to only run Dscaler instead of a good progressive scan DVD player. I personally would think that would be an impractical setup.
