How bad do these artifacts get on 720p to 1080i if you are using a decent quality converter? primarily how good a job does the Pioneer Elite series do on this conversion?

I can't answer all of your question but the Pioneer Elite doesn't do any 720p conversion. It accepts 480i, 480p and 1080i. It does not accept 720p. The conversion from 720p to 1080i has to be done outside of the TV (in the STB).


It does convert 480i to 480p and it does that very well. I don't know which chip they're using but the Elite's have one of the best internal line doublers used in RPTV's.

What are the benifits and negatives of converting from one to the other?


Also, if given a choice would you:

A)convert 720p to 1080i

B)convert 1080i to 720p

C)Watch 1080i and 720p in native form
WHY?

DOOOOOH!

This is a good question and I wonder why most on this forum would recommend setting a model 6000 to display HD in 720p when the HBOHD source material is 1080i ?


Can 720p actually help a 1080i source since motion artifacts in the 1080i source cannot be eliminated ?


The horizontal resolution of 1080i is 1920 lines, right ? So when you convert it to 720p what happens to that horizontal resolution ? I would think that it stays at 1920 even though the 720p 16X9 standard calls for 1080 lines of horizontal resolution. So you wind up with 1920 X 720p !


Wouldn't it be common sense to just display the resolution of the native source ?

I remember reading somewhere that HBO-HD is not using 1920 lines of vertical resolution in there 1080i broadcast. They where using a smaller number. I do not know if that has changed since I read the article.

You are correct. It is nonsense to view 1080i downconverted to 720P. The result is a softened picture and any interlace artifacts are still visible. I have an Expressvu version of the 6000 and I watch ABC and CBS in their native formats.
