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