High end receiver with their Upconverting VIDEO

doggie750

Is this a fact that these receivers do convert 480 to 1080? Please advise. If so why do we need to invest on something like BLURAY and HD players??????????????
:mad: :eek: :cool: :rolleyes:

For starters ...

- "These Receivers" and "High End" are at least imho mutually exclusive terms ...
- Why do you care if ANY receiver or preamp upconverts ? ... go direct to the display from the source ...

Beyond that ...

- Any upconverted signal regardless of how good the hard / firm / soft ware is will not look as good as a signal that originated as higher definition ...

Poor example but ...

If I have a hockey stick and ...
I break it into 1000 pieces and ...
I then remove and destroy 500 of the pieces and ...
I then by some means guess at what the 500 missing pieces should look like and ...
I then some how build them and ...
I then combine my 500 original and 500 reconstruted pieces ...

Will the finished product be as good as my original hockey stick ?

A possibly better example ...

Think of a video image at any given instant as containing a screen full of boxes containing color ... for the sake of simplicity we'll make these square boxes with our screen containing 8 across by 4 down ...

|X|O|X|O|X|O|X|O|
|O|X|O|X|O|X|O|X|
|X|O|X|O|X|O|X|O|
|O|X|O|X|O|X|O|X|

Assume that all the information represented by the X's and O's are in the original HD picture but that all the information made up by the O's won't be present in a SD picture i.e. it will only contain information represented by the X's. An upconverting player will attempt to recreate the O's based on the information it has in the X's and while it may do at least a fairly "intelligent" job of this it will still not be as good or the same as what was in the original HD source material.

We all know that.......Whatever the input signals couldn't be generated a higher definition regardless the system is. However the technology still states that it is do able...Argument still open......:cool:

PolkWannabie

I think you better read your reply ... Maybe it makes sense to you but I can't make heads or tails out of it ...

If you are asking if HD can be generated from SD ... The answer is yes it can ... But it won't be the same as the original source material in HD for the reasons stated previously ...

If that's enough for your purposes then it is ...

I know but my argument is seeking from one in this forum had demo and conducted some analysis. :cool:

PolkWannabie

Demo ? ... Yes I've seen the difference ( Side by Side ) ... Good upconversion is just that ... The problem from my perspective at the moment any way is I'd rather not have two $1k decks for different formats ... But I suppose that won't get resolved any time soon.

At the moment I'm okay with upconversion until the dust is more settled then it is now ...

I have a HT that uses a front projector with HD. My inputs to the projector are DVI, component, S-Vid, and Video. My VHS, DVD and TV box are connected directly to the projector. The audio is connected to the reciever. When I change from HD TV to DVD I need to switch the audio on the reciever and then switch the video with the remote to the projector. This can be a pain in the ****. I would like to get a new reciever that allows me to change both audio and video with just the reciever remote. So I think I need a reviever that converts all the video input signals to component or DVI.

PolkWannable are you saying that this video convertion will degrade my VHS video signal? Will the switching in the reciever degrade my HD TV and DVD signal also?

Currently these are my connections to the projector.

VHS1=S-VID
VHS2=Video
HD TV=DVI
DVD=component

Degredation is not related to conversion per se ... but it also doesn't need to be done in more then one place i.e. by an upconverting dvd player to the native mode of the tv or by the tv of an inbound cable and/or dish signal.

However, the more components one puts a signal through the more CHANCE there is a degredation in one way or another ... personally I like to keep the signal paths as simple and short as possible i.e. no need other then potential convenience to send a video signal through a receiver / preamp ...

It would seem ?! that the simpler solution would be to either use ( assuming you have ) or get an intelligent universal remote that allows one to program macro buttons to perform switching of multiple components i.e. audio and video simultaneously.

nope, NEC and a few others have announced they've got the chip/processor to do Blu-Ray/HD-Dvd/DVD/CD in one player, to be shown @ CEDIA possibly this year, mass production in 2008 supoosedly LG already has a prototype unit
.... But we will see.....

PolkWannabie

Nope ? ... Read the last line you quoted ... Again ...

doggie750

fair enough.................
"If they build it, we will see it...."
