streaming video is all the rage these days but convenient as it may be it's
0:04
still limited by a number of things how fast your internet connection is whether
0:09
you're subject to the more and more common data caps on your service and
0:14
whether you're willing to deal with recurring billing from someone like
0:17
Netflix so maybe it isn't too surprising that Blu-ray discs have found popularity
0:22
among people who are serious about movies and home theater enthusiasts
0:26
despite the fact that Optical media as a whole is in Decline which you can learn
0:30
more about up here it might seem like a
0:33
shame that the optical disc is seen as a technology that's becoming obsolete
0:38
since Blu-ray has only been on the market for about 10 years back in the
0:41
early mid 2000s it became clear that HDTV would be as commonplace as old
0:47
school TVs in the near future so there was a lot of interest in developing a
0:51
disc format that had high enough capacities to hold full 1080p movies
0:56
especially as standard DVDs generally can't even hold an hour of HD video so
1:01
the solution was to develop a disc that used blue lasers instead of the
1:05
traditional red lasers you see blue light has a shorter wavelength than red
1:10
meaning that the little Pits on an optical disc that store the information
1:14
can be made smaller the result was that many more of these little pits could be
1:19
burned into a Blu-ray than a DVD in fact standard Blu-ray discs can hold over
1:24
five times as much data as their DVD counterparts and although Blu-ray had to
1:29
comp compete against a rival format called HD DVD for a few years that used
1:34
similar technology Blu-ray ended up winning this new VHS versus betamax
1:38
style format War due to Major Movie Studios supporting Blu-ray the
1:42
incorporation of Blu-ray drives into the PlayStation 3 and consumer confusion
1:46
over the difference between HD DVD and normal DVD so with that Blu-ray stands
1:51
alone as the one format of choice for HD video but what does it offer that
1:56
streaming services can't other than the obvious ability to function even if your
2:00
router cuts out or because your roommate had to microwave his freaking burrito
2:04
one of the biggest draws isn't the video but the audio Blu-ray discs have enough
2:09
capacity to support lossless audio formats like Dolby true HD and dtsh HD
2:14
Master audio which offer up to eight discrete channels and Incredibly
2:18
detailed sound as long as your speakers and receiver are up to par we're also
2:22
seeing movie studios release extras like deleted scenes exclusively on Blu-ray
2:27
meaning they often aren't available on streaming Services the tech isn't
2:31
resting on its Laurels either as higher capacity Blu-rays holding fulllength 4K
2:36
movies are set to hit the market this year along with support for new digital
2:40
audio standards like Dolby Atmos and dtsx which offer much more precise
2:46
spatial orientation of sound than traditional multi Channel setups by
2:51
contrast streaming services don't yet offer lossless audio even 4K video alone
2:55
is too much for the internet speeds that many average users have and can chew
3:00
through 300 GB of a monthly data cap quite quickly so if you're a real movie
3:05
buff you might not want to start thinking of optical discs as coasters
