hey guys im a bit confussed. i bought a sony bravia hd tv 40inch and a sony bravia theathre sync surround sound system that upscales to 1080i but not 1080p i did'nt hear of 1080p untill i bought the thing but im not cpmplaining about the quality of the picture' as i watched die hard four on it last night for the first time & i've never seen such a sharper or a more smoother picture before & the SOUND i'll leave that for another day, but my question is that is there a big diffrence between the two formats as one of my mates said that there was he seems to know about these things. so if anybody could shed some light on this would be much appreciated!!
I heard 1080i has better frame rate compared to 1080p, I don't think you would notice much of a difference in quality. Just make sure the DVD player is 1080i and the DVD's are 1080i for best results.
Don't worry about 1080p if your player is just a up converter. Your tv will scale it to its native resolution anyways. I think ChubbyInc is confused. All dvd's are 480p none are 1080i. Regardless of what your upscaler is set to you still just have a 480p source. If you get an hd-dvd or blue-ray player then the whole progressive, interlaced, frame rate, etc. will be more critical.
club42 you said some good things but just to clarify, DVDs are mastered in 480i not 480p! HD DVD and Blu-ray are mastered in 1080p/24 (for movies). The frame rate is never an issue as long as its matched properly to what the TV can except. 1080i doesn't have a better frame rate than 1080p. It depends on the source material and the quality of the video processing and compression. There will not be any difference between 1080i and 1080p that are derived from the same source as long as 1080i is properly de-interlaced (to 1080 progressive). Ced
so theres no real diffrence if the dvd player upscales to 1080? but say for instance i bought a blu-ray system will the quality greatly improve or would it be similar?
I think all newer blue-ray players on the market right now are 1080p. Thanks for the info diabolos. That makes sense that they would be 480i. So when a standard dvd player is set to 480p is the player de-interlacing so the tv doesn't have to?
Apparently I mis-read SNOOKERS original message, thought he had a 1080i player....... And I was referring to HD-DVD's or Blu-Ray discs not SD-DVD 1080i has double the frame rate due to interlacing, but half the resolution of 1080p, might not matter for movies, but is more important in gaming or for watching sports shows. Your TV might not support interlacing, so that wouldn't be important. All next-gen movies are encoded in 1080p
Again I think you a confused of the concept here. 1080 i and p both have 1080 lines and the same amount of information. If 1080 were displayed on an interlaced tv then yes you would have two 540 fields interwoven but since no current tv's are 1080i (just 720p capable of displaying 1080i) as all digital HD-TV's are progressive display's and no matter what source the tv will scale to it's native resolution. So if a player is outputting 1080i the tv will de-interlace the two fields before they are displayed. I would like to see a tv on the market not support interlacing. As for gaming I think you are confusing frame rate with "refresh rate" "response time" or "flicker" depending on the tv type.
Yes indeed. @ chubbyInc, I think you are a little mis informed as to what interlaced scan and progressive scan are. I also don't think you understand the role source material and Video Processing play in the world of digital tv.
