What is the difference between encryption and protection? And what method suit you best and offers the better protection. Well lets start with encryption, this is simply the masking or dissembling or fragmenting of data, while protecting your data, takes on a different practice completely, it would generally mean using some password on your content. There is however another way, a more hybrid approach , which would entail using both to offer a more consummate defence to pilfering, we never really know, but in todays tech space when someone or websites say they offer encryption, it may simply mean they encode the data with password protection, so be careful. Make sure to choose companies that offer encrypted video streaming or cloud video encryption and feel safe.As I continue writitng this post, lets have the common understanding that when encryption(is the process of as we said masking your video) is mentioned it means the masking of data using keys specifically HLS or via DRM (Digital Rights Management). We already spoke about HLS in a previous article, please click the link on HLS above in order find out more information.
Lets now discuss DRM because it has many different components or layers of protocols which make up the protocol:
- Different Video Streams
- Video availability by region
- Video availability by device
- Video availability by software
- Last but not least, Adaptive streaming
Different qualitative and quantitative
So basically , encryption is broad blanketed preventative measure which is binary, meaning, it is either you have rights to access the video content or not, while DRM has different layers of filtration .so lets discuss each method individually:
Different qualitative and quantitative streams for different price brackets
This is the first component or layer we will discuss. It is basically a pay per quality model, where the highest quality offered is 4k , and the lowest being SD. If you pay the highest price, you get 4k and if you choose the lowest payment model , you get , you guessed it, the standard definition quality content. The rate of the stream is affected which immanently affects the resolution and quality so it is by definition qualitative.
Premièring in one place exclusively? Then you don’t want any other country to see it first. Want to control the market and distribution (like they tried for DVD and failed)? Or, are you barred by law to show certain videos in certain places? Then, you need region-specific management of your encrypted video streams.
This is location specific, so if you have content which you want to be aired in North America, but not anywhere else, then this layer is what would be chosen, so this is why it is called Region specific video.
This is vendor specific, so companies may brand or their media so it can only be play by specific branded media device, example appleTV, Amazon Kindle, itunes etc
There are some NLEs that refuse to play certain video codecs, primarily because of operating system constrains and it doesn’t support the type of codecs unless a license is paid for.
