So as I try to absorb all this great information that is being discussed on the AVS forums...I have sort of come to the conclusion that there are afew companies out there that are building video processing chips and they are slowly being implemented into consumer BD players.

Going to the various websites of these chip makers does not really tell me if one is better than another or does the same things better or worst.

I guess maybe I am hoping that some on here would be able to try and simplify some of the features and functions of these different chips and allow me to some how rank them in my mind.

THANKS!

The other major company is Sigma: http://www.sigmadesigns.com/public/Products/vxp_selection_guide/vxp_selection_guide.html

The simple answer is to read every recent post by cpcat.

Don't forget that simply having a given secondary video processor installed in a player (or receiver) does not guarantee a great product if the device manufacturer drops the ball with implementation.

And...although is is getting very long in the tooth and outclassed by the products mentioned above, the Faroudja DCDi (http://gnss.com/) solution is still very commonplace in lower priced units and probably deserves a mention.

If you compare the Anchor Bay (VRS (http://www.anchorbaytech.com/products/semiconductors/index.php)) to the IDT (HQV Reon (http://www.hqv.com/)) to the Marvell (Qdeo (http://www.clearlyqdeo.com/)) to the Sigma (VXP (http://www.sigmadesigns.com/public/Products/vxp_selection_guide/vxp_overview.html)) one common theme emerges: they are all very good. In addition, the VRS, VXP, and HQV chipsets have all been used in external video processors with excellent results.

What we are experiencing now is very commonplace in the electronics world. These products and technologies start out in high-priced specialty equipment and eventually migrate downward to consumer level products.

Don't forget that the Marvell solution has been used in an external video processor too. Sure it is for a 4K projector, but it still counts.

Good point!

Thanks :)

I'd want to see some less regarded stuff as well so people can get an idea of just how much better a RadianceXD would be than their crappy TV.

How about Pixelworks? Mediatek? Or do you ONLY want chips that'll show up in BD players?

well...when I started the post, it was for chips that are showing up in BD players and then slowly in TVs...
but any discussion or insight on the what the various chips/processors are doing would always be good knowledge to have.
Thanks

Heres some good background reading to begin with:

Basically, what these processing solutions are doing is:

1. Noise reduction
2. De-interlacing
3. Scaling

And their particular claim to fame (when they came out) is they could do it to HD video as well as SD. Other processor families have emerged as well. The latest Faroudja solutions don't seem to be as competitive as they used to be, but Pixelworks seems to be pretty good second tier processors.

Much of the performance comes from the implementation as well as the chip type, though.

Edit: I wouldn't chose a player or amplifier because of the video processor type, as long its one of VRS/HQV/VXP/QDEO. The real things to watch out for are whether the processor will process both digital and analogue video, and SD and HD video. Sadly you cant take that for granted.

Just so no one is confused, that is a 4K resolution projector. The pj and vp are sold together by Meridian and it costs 185K dollars.:eek:

I take it that when you say process HD video that you are not including 1080/24 correct?
And so, how will we know if its processing SD and HD?...owner's manual?

In general you'd want to leave 1080p24 alone and unprocessed. There may be advantages in applying noise reduction, but this depends on the user.

Whats it processing? It depends on the serttings of the source equipment. Many video processors have useful information displays that give input and output video formats.
