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 could be made smaller the result was that many more of these little pits could be burnt 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 compete against a rival format called HD DVD for a few years that use 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 freakin 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 ts HD master audio which offer up to 8 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 full-length 4k movies are set to hit the market this year along with support for new digital audio standards like Dolby Atmos and DTS X 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 gigabytes 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 quite yet lynda.com on lynda.com you can learn tons of different kind of things with very passionate and well-informed teachers with video courses on demand so you can learn on your own schedule and at your own pace not at the pace of that really passionate well-informed teacher you just learn they just help you don't worry about it you can browse each course transcript to follow along just in case you missed something or searched for an answer and skip to that point in the video if you need to have something we spoken to you you can take notes as you go and refer to them later on you can download the tutorials to watch them on the go including access on devices like iOS and Android you can create and save playlists of courses you want to watch or customize your Learning Path or share it with friends and colleagues and team members or when you can make a group of people that are all trying to learn one thing it's all fine your lynda.com membership will give you unlimited access to training on hundreds of topics all for a flat rate just starting at $25 per month whether you're looking to become an industry expert you're passionate about a hobby or just want to learn something new check out lynda.com slash tech quickie and sign up for a free 10-day trial today if you liked the video like it if you dislike the video dislike it check out the comment section down below leave a comment if you want to do other cool videos and you have ideas for it check out channel super fun there's really super fun things over there thanks for watching don't forget to subscribe we'll see you next time
