AOD vs Blu-ray revisited...
- Thread starter PC-Engine
- Start date
I'm not too educated on the specifics of the various compression formats but it seems to me that MPEG4 is seeing wider application than initially intended (webstreams). And MPEG4 isn't just MPEG4, you have WMV9, QT6, h.264, DivX, Xvid and others. There is no doubt that MPEG4 is being targetted at HD content today.
I am sure those are just different MPEG4 implementation. MPEG4 is a standard afterall.
MPEG4 is seeing wider application, because its low bit rate. That's very attractive to everyone, things that cut corners for bandwidth, allows people to make more money for given resources, you would be a fool not too take advantage of it.
There are some interesting codec comparisons here:

WM9 isn't on this particular test, but there are other MPEG4 based ones.
If the coming generation of disk based formats are going to replace VCR's at some point, then high compression codecs like these can't possbily not be worth having. Then again, that isn't the Hollywood studios concern.

You are quite ignorant...
Do you know who is responsible for the the push in the industry and further development of Blu-Ray ? Sony's own Broadband Network Company.
Do you know who is the boss of BNC ? Ken Kutaragi.
Now, shut up.

Hey, 's why I'm asking. ^_^ It has to be at least 67% more efficient to catch up with the storage discrepency, and of course if it does it through a process that makes other concessions, those are going to be kept in mind too. (And I can't even IMAGINE if it's talking about worse scratch resistance and such. They wouldn't last a week at Blockbuster.cybamerc said:
I get enough fragged DVDs as it is.)There just seems to be little information on the comparisons at all levels, which is why I question people's absolute claimss at this point in time.

Eh 40% should do it. Anyway, since they're different codecs they produce different results and as such you can't make a direct comparison but at low bitrates MPEG4 is widely considered to be 5-7 times more efficient. The difference may decrease (and I don't really know if that holds true) as the bitrate increases but keep in mind that with MPEG4 you can make a great looking HD movie (1080p) that fits a DVD and HD-DVD offers more than 3.5 times the capacity of a DVD9.

If that were actually the case from their perspective--and there were no other concerns--the industry wouldn't even bother switching ROMs, just making DVD players that support new codecs and continue along the same way. Players would pretty much be as cheap as ever, stamping the disks the same as ever... They'd just be selling movies in "Widescreen Edition," "Fullscreen Edition," and "HDTV Edition." Hehe... I'm guessing there's a bit more involved, from cost, technical, and other perspectives. (Like content control and all that jazz the RIAA and MPAA are champing at the bit for.)

Well, there are several red laser HD formats being proposed. The problem is getting others to support them.
Also, you need higher capacity media for data storage, video recording and so forth. Compression only takes you so far.

Im still praying for those Taiwanese guys to commercialize their thin film near-field optical lensing material ... in theory it can work (flat lenses have been proven to exist, both in the microwave region and more recently for optical wavelengths too). It will make blue laser tech extremely expensive trash (the wavelength of the light isnt all that relevant to the spot size with near field lenses, so you might as well stick to lasers which are not expensive to produce and unreliable).

HD-DVD isn't really made for HD content.....its just DVD modified to use a Blue laser with some add data storage and not much at that.
Um what are you talking about??? So 1080p isn't HD? Did you even read any of the posts in this thread??? If HD-DVD is not for HD content than what is it for then??? Are you saying HD-DVD will contain standard definition films and have 10-20GB left over for extras just so it can be contained on a single disc???

To be honest i don't really care "who the winner is". All i care is that they give us an understandable and reliable standard, possibly cheap too. If it turns out to be HD-DVD, cool. If it's Blue Ray, cool. It's just a name after all. It's not like they're very different after all...
Just as long as we don't have 2 different standards, with a group of companies supporting one standard and another group of companies supporting another standard. Forcing us to have 2 players.... Nah not for me, i'm geeky but not THAT geeky...
