Holographic Versatile Disc....1 Tbytes...

[Paul2]

HVD 1 Terabytes

I got this from a different forum...and imagine that it can store all the episodes of the Simpsons in 1 disc.

First time comes to my mind when i see 1 Terabytes of storage on the same 12 cm optical disc is...

umcompressed high defintion video and mulitple uncompressed 24/96 surround sound, that means producer can storage 24/96/6.1 surround sound in english, audio2 in spanish 24/96/6.1, audio 3 in french with 24/96/6.1, and it goes on...

and maybe perhaps 3-D video.  similiar to how the a guy put many cameras around 360 degrees and shoot video in it for the PlayStation 2 demo disc DVD.  I watch the video and i was surprised to find out that i can rotate the video angle in 360 degree with my dual shock 2 controller.

Think of this 1 Terabytes disc possibly call holographicc versatile disc as the "uncompressed High def 1080p" of the lossy compress high def 1080p find in Blu Ray and HD-DVD.

Another good example is, such as DVD-A 24/96/5.1 versus Dolby Digital 5.1 or DTS 24/96/5.1 compression.

I thought after HD-DVD/Blu Ray, we will probably be able to watch lossless video compression of 1080p/30 if it manage to get to about 125 GBytes single layer and 250 Gbytes dual layer.  But this, this HVD can store up to 4 layers, each 250 Gbytes making it possible to store "uncompressed 1080p video".

But of course, we want flexiblities too.  Meaning, it can support uncompressed audio/video in high defs, lossless compressions, and the current and old lossy compression of MPEG-2, MPEG-4, and WMV-9, or VC-9 all in a single player.  So the producers can decide if they want to just put the all the simpsons episodes in 1 optical disc in lossy compression, or they wanted to put a 2 hours long movies say Finding Nemo in 1080p uncompress video....

I think the problem with this is, can the general audiences be able to tell the difference between lossy compression over uncompress HD 1080p?

Because we already seen how great the picture look in 480p dvd video in MPEG-2, and i once had convert a save pic from BMP (uncompress picture) to JPEG with about 12x compressions or 12:1, and at normal view.  i can\'t tell a difference at all.  Nor can my friend.  Unless I be looking really hard and close up, and do A-B comparison, i can tell the JPEG looks a grainer then the BMP...

anyway,

i am a math psychotic, so let do this math problem... :nut:

1920 x 1080 x 60 x 24 x 60 x 120 = 21,499,084,800,000 bits of digital information.

Or about 21.5 Tbits or Terabits of information...tera = trillion...

divided by 8 = about 2.68 Terabytes of information.

*put face in shame*:shy:, even with this much storage, its not possible to store up to 2 hours of video in uncompress video...its require up to 2.68 Tbytes and with sound and all, it will make it up to 3 Tbytes or more...

well, then lossless compression....:thepimp:

If you are curious on how i got those math numbers that seem to come out of no where and multiply them....

well

1920 x 1080 is the pixels or resolution.

24  is 24 bits RGB.

60 is 60 frames per second.

another 60 is 60 second in 1 minutes.

and 60 minutes in an hour.  or "120" minutes for 2 hours...

and then you mulitply them all to get total storage, bit rate...

if you have any question about this math, ask me and i would love to explain it. :nut:

[Paul2]

anyway, since i double post the above post.  I might as well give you this slight correction.

actually, film runs at 24 frames per second.

So, its possible to store up to 2 hours in 1080p/24fps/24bits color...

but of course, not feastible.  One can reduce the color bitrate to even safe more data, say from 24 bits RGB (4:4:4 YUV sampling) to 20 bits 4:3:3 YUV or 16 bits 4:2:2 YUV..  But still not enough bandwidth actually for other stuff to throw in (like audio, extra, etc)...

But if you want the best, and if a digital high defintion video camera can record the 1920x1080 x 60fps x 24 bits color then...it wouldn\'t be enough...

*enough rambling, me runs and hide*

[Paul2]

*damn it, triple post* :shy:

since i accidently triple post it,

i might as like to add that after Blu Ray/HD-DVD, we will get a new format similar to HVD (holographic versatile disc) for the next\'s generation media as early as around 2010ish...

timeline table....

*1983-1984 ....first introduction and release of a new optical disc containing digital data that change the way we listen to music.  Its call CD player... Storage 650 Mbytes.

1996-1997 ...first DVD player to hit the market changing the way we watch movies and video and listen to music too. Storage 4.38 Gbytes...or rounding to claim it 4.7 Gbytes or 4,700 MBytes, single layer and 8.5 Dual layers or 8,500 Mbytes. *in reality, when divided it in 1024, its roughly 8 Gbytes, aka 8,000 Mbytes...

future....
*?2005-2006?
Blu Ray and HD-DVD...it got everything that dvd player got but more.  Such as High Definition video and support 1080p HD video, lossless compression 24/96kHz audio and more....
storage: HD-DVD AOD, 15 Gbytes single layer and 30 Gbytes dual layers.
Blu Ray, 27 Gbytes single layer and 50 Gbytes dual layer.

*?2010ish?
HVD format...or the such...
storage: 1 Tbytes quadruple layers...each with about 250 Gbytes.

and beyond...

:nut:

Not exactly on topic:Which PS2 DVD demo are you talking about?

[Paul2]

ok, finally get the chance to answer your question...

i believe it was back in early 2002 when i used to subscribe to OPSM2 magazine.  It contain a DVD demo disc for each issues.  One issue, it contain the show of E3...electronic expo e?  of 2001.  In it, a guy come up with cameras where you can record 360 degrees of video.  He place it on the floor in E3 and move it around and he try to be careful not to let the camera record him as he move the camera around the place in E3.  Then it was edited in the computer to match each camera video pictures to a 360 degree...  Its pretty cool and neat because i can rotate it to watch this angle of this part or that  angle to see layout of E3.  I saw FFX of Tidus pic on this ball...

Around that time, a music video for Britney Spears also uses that technique 360 degree angle where she was sitting on a car with some dancers singing while the car is driving.  You can rotate it to see the front of the car, the back, the side as these dancers and people were dancing around...

Thanks for the info and math Paul.  HDV has been years in the running but nice to see some progress from a mostly European competitor.  Hi-Res audio is planned for both formats, and what I\'ve been hearing is lossless support.

Here\'s anothe blurb on a 2TB memory card:

And just fyi these topics are better suited in OT.  You and I are the only ones who are keeping up with it.

[Paul2]

dman

a very small memory card can hold up to 2 TB...i remember seeing that somewhere too...

and a decade ahead of HVD?

interesing...

[Evi]

That\'s a LOT of information...wow. I can\'t imagine what video is going to look like in years to come. I think they really need to UP the quality at the movies significantly than they are now...blah!!

http://www.beyond3d.com/forum/viewtopic.php?t=16690

the ability to do at least the newest MPEG-4 AVC High Profile video codec at 1920x1080p/24 and 1920x1080p/30 with 16 Megabits/sec or greater VBR that can visually match a D-5 master tape (that spec. right there hands down beats the pants off a filtered 1080i D-VHS tape)... and either 6 channels of uncompressed LPCM at 24/192 resolution or 8 channels of uncompressed LPCM at 24/96. ~27 Megabits/sec would be alloted for just audio. That would seem to point towards a total bitrate of 54 or even 72 Megabits/sec.

 I\'m not much into Sony hype but I\'m extatic they\'re even considering 8 channel LPCM.

[Paul2]

I am not too thrill about 8 channels since my living isn\'t that super big, its roomy enough for my house, but imagine placing 8 speakers around my house....

To me, 6.1 channels sound perfect for small-medium living room...

oh, most people remember that film are 24 frames per second, but they didn\'t realize that the audio they record are 20 bits 48 kHz....

so, its will uses less bandwidth than its needed...in uncompressed format of course or lossless compression...

20 x 48,000 x 7 channels...

about 6.5 Mbits...

with 3:1 lossless compression = 2.1 Mbits....

maybe with this much higher storage that Blu Ray and HD-DVD is given out, newer film may record higher than 20/48....

[Paul2]

oh,

I would like to see how well each 3 codecs will look side by side comparisons:

such as MPEG-4 versus WMV9 versus MPEG-2 by doing a fair comparisons of same bitrate and resolution and stuff...

Its a good thing Blu Ray and HD-DVD included MPEG-2 because for its to be backward compatible with DVD player, it has too...and more flexibility.

They\'re doing 24/96 audio.  DD and DTS are already downmixed to 48kHz.

From my experience WM9 (VC-1) looks better at low bitrates and MPEG-4 the winner at higher bitrates.  WM9 likes to smooth everything out while the other exhibits blocking if you don\'t give it enough juice.  Give both a high bitrate though and mpeg-4 edges out for clarity and sharpness.  People still report seeing color banding on VC1 encoded discs.

When you throw in the money factor licesning for VC1 is less than half of what mpeg-4 costs.  VC1 is just MS by istelf while MPEG-4 is almost all the big players, including Sony, Apple, and even Microsoft.

Bottom line is both are nice, efficient codecs and neither blows the other one out of the water.

OMG.... thats crazy
