 Post subject: Upscaling Laserdisc 1080i or 1080p??

Hi,

I use my Onkyo TX-NR515 to upscale my LD. I find that it looks ever so slightly better at 1080i than 1080p, but Im unsure as to why this is. Can anyone explain please?

Thanks in advance.

What kind of display are you using? If it's not native 1080p that could be part of the reason. If it is native 1080p it would apply another level of processing to a 1080i signal. The end result may be more pleasing to your eye. It's hard to say.

Some tv sets have some enhancement options only available on lower resolutions. Your tv is definitelly deinterlacing into 1080p as no fixed pixel set is able to display 1080i.

There are many thumbs of rules. Most recommends least amount of conversion is likely to give best picture. But it all comes down to what looks best to you.

Ok, this makes sense. I tried displaying it at a lower resolution (480p and 720p), but it certainly wasnt as good as the 1080i and 1080p interpretations. Im not averse to watching the Panny LX900 straight into the TV, but it definitely looks better through my AVR thanks to its Qdeo chip, It makes the picture heaps cleaner and the colours seem more stable.

I have an Onkyo TX-NR626 and upscale to 1080i...saying that I don't currently have a 1080p display so I can't say if it looks better at p. I certainly think the Onkyo upscaling is exceptional though!

IIRC onkyo 626 has the HQV Reon chip for video processing. HQV was the benchmark in broadcast video. Their original HQV processor was 3 or 4 decks on top of each other filled with FPGAs. It retailed a hefty $80,000. In early 2000s, they spent so much of their resources into creating a SOC which will do all that for lower cost and space. This gave birth to HQV Realta. It replaced the 90s multideck super expensive unit into a tiny chip and much more affordable. Unfortunately this move was also the doom of HQV. They spent their entire resources and the return wasn't enough to compensate. They bankrupted and was sold to IDT.

IDT wanted to make Realta more affordable. They took the algorithm and created and asics. Its called HQV Reon. The difference is Realta has more processing power and also software upgradable. If better algorithm is available, you can upload it to a Realta chip. Reon has a little less processing power and can't be updated. Later IDT came up with HQV Vida which replaced Reon. The principal is the same but has similar processing power as Realta and runs on newer algolithm especially for noise reduction.

In video processing the chip used tell you too little as you can imagine. Its the implementation that matters. From what you said, onkyo must have implemented HQV Reon correctly.

I did a fair bit of reading on the Onkyo 626 and many other similar systems before buying it, I don't remember reading about HQV. According to the manual it uses Qdeo by Marvell for upscaling up to 4K. Having only a 1080i display 4K is a bit overkill for me but it certainly makes laserdiscs look lovely : )

When I can get my a** in gear, I am going to replace my Sony DA2ES AVR with a Sony DA3300ES AVR. The 3300 has the Faroudja trademark on the front of it. The Faroudja is software that can upscale 480i (or p) composite video to 1080i (or p) HDMI video. I have no experience with Faroudja so I hope that it will do the LD video justice.

Project 1:
I have to remove my 27" Wega SDTV first and that will be difficult as I just don't have the strength now. I am going to try to slide the Wega out onto a TV stand with casters so I can move the set out of the living room. Once that is complete, I will have to make 2 shelves to put in the place that the Wega was. The top shelf will be for the center channel speaker. The bottom shelf will be where the Sony Bravia HDTV will sit. Below the bottom shelf I will place my Sony UBP-X800 player on the left and on the right will be my Toshiba HD-A3 HD-DVD player. After the latter is complete, I will then replace the DA2ES AVR.

Project 2:
My next project is to assemble a set of heavy duty shelves capable of holding 330 lbs. per shelf. There will be 5 shelves so the total weight can be up to 1650 lbs. I plan on putting some 150-200 CED's on it so the shelves will have to be STRONG. (I may assemble the shelves before moving the Wega.)

Project 3:
Another project that I have to complete before snow flies is to install 2 snow melting mats on my deck. The 5 foot mats can melt snow at the rate of 2"/hour. Up to now, every winter I have had to fight snow on my deck. I had difficulty shoveling it. The wood deck (for some reason) converts snow to ice making shoveling it hard to do. I will have to buy at least 2 more mats to complete a path to the deck gate. It would be so cool to just turn on a switch and have a path on the deck appear after an hour or 2.

Ad nauseum.

Get that wire metal shelving, that holds I believe 400-500lbs per shelf.
They have it at any home store and also cosco very cheap.
Only issue is that you need to put something like cardboard or plastic on the bottom so nothing falls through.
They are also nice that they do have wheels and you can wheel them around.

I use them but only have a maximum of 2 shelves. not 3 or 4.

Too late. I already have the shelves. I do plan on putting oak plywood on top of the provided particle board to increase the shelf strength. Right now, I am trying to figure out what to put on top of the CED's to keep the dust off them. Towels and sheet plastic have been considered. Something will come to mind.

LOL Good deal.
Its really hard unless you build a closed cabinet type with doors on the front, but even then a little dust will get in.
Best to just keep the duster handy.

It is too bad that they don't make very large VCR covers that could fit over all the CED's on a shelf. I do agree that periodical dusting of the CED's maybe the only solution.

I just want to get these darn CED's out of the living room. They do take up a lot of floor space.

I find images looking "processed" when I let the iscan HD+ go beyond 720p
THe 4K Panasonic screen does it's magic when I leave all processing set to off.
720p for me :wave:
