1. No worries. I'll try my best to keep the discussion non-technical and try to explain the technical bits in an easy to understand manner. 2. The 1080p resolution is just a standard. Pretty much the industry got together and decided that that was a sweet spot based on where TV technology (and prices) were heading, how much storage (and how costly) it was going to be, etc. It's just a standard resolution. If the industry wanted they could store (less) higher resolution content on a Blu Ray disc but they have the standard so that all the TV's, Blu Ray players, etc. are compatible with one set of rules. I'm trying to think of a standard in a non-tech realm... hmm... How about the beverage industry. There's a standard can size for soft drinks. Sure somsone could make a bizarre triangle based prism as their can but the standard around the industry utilizes the cylindrical base, which is why cup holders are cylindrical and vending machines are designed to dispense such a form factor. 3. Yes, bit rate is also a concern of playback. Pretty much you can't put more cars on a highway than there is road on the highway... unless you mean to create disaster. I'll speak more on this below when I comment on the Wikipedia stuff but they've (the movie industry) pretty much created a standard top bit-rate for audio/video on DVD movies so that all DVD players can play all the content. And now I'm pretty much going to repeat what I just said for the Wikipedia stuff As for what Wikipedia had to say, it's simply listing best practices and standards of audio/video (content) quality on DVD's (medium) for the movie industry in order to maintain mass compatibility. These standards are huge in the movie industry so any dvd (or blu ray which has its own set of movie industry standards in terms of max bit-rate/resolution) player can play all the content that it is meant to play with no problems. These playback devices are highly specialized and designed to perform certain tasks very efficiently (and the standardization also makes them cheap to build as parts are made in bulk to perform these tasks). A game console doesn't have to follow these same restrictions and guidelines for audio/video in the context of a game. So the video/audio quality of cutscenes in games don't follow these guidelines as they aren't being played back by any random home DVD player. |
i just realized i still dont understand the benefit of faster bitrate and such. does bluray have a higher theroretical bitrate, what does that mean for its visual quality.
which brings me to my next point.
cnet.com had a recent article about different 3D tech, and they said that bluray is the only way right now to get full 1080p/24 3D (i know no ps3 game can do this). as it has a much higher bandwidth than broadcast TV, and i assume DVD. So it can do framepacking 3d (2 frames stacked on top of each other, each at 1080p/24). while broadcast Tv does either side by side or top and bottom 3D, which severly cuts down the resolution.
So i was wondering, with the recent rumors of xbox having an update to be able to finaly do true stereo-scopic 3D. how will it be able to do framepacking 3D, like the PS3 can (though obviously its not 1080p) due not only to bluray, but also due to it higher bandwidth HDMI 1.3b port. xbox uses DVD and HDMI 1.2. so can DVD do framepacking, does HDMI 1.2 even allow for that.
if DVD can do it, why have there been framepacking, stereoscopic 3d for DvD(as far as i know).
