What is HLS Encryption? Is HLS Encryption effectively secure against piracy?

HLS Encryption

HLS Streaming ( HTTP Live Streaming) is a streaming protocol that is used for the video content across computers and mobile devices. HLS encryption refers to video streaming using HLS protocol where the video files are encrypted by using  AES-128 algorithms. The key exchange takes place through the secure HTTPS protocol and also allows for the usage of initialization vectors to optimize the protection.

You can protect your videos with 128bit AES (Advanced Encryption Standard) HLS encryption to protect your videos from unauthorize download attempts with tools and video downloaders such as Internet Download Manager. Making it by far one of the most secure platforms to stream and secure your videos and it makes sure that your videos are secured using the latest protection technologies.

How To Protect Videos Using AES – 128?

The HLS mentions only one aspect of key retrieval which is by using the URL from which the key can be loaded should be a part of the manifest file. Most often, we see a number of different approaches for protecting the decryption key:-

 1. By Protecting the manifest:-

This is the way through which we can hide the URL to the decryption key. It does not provide more strong security as the URL might leak or could be intercepted on the network.

2. Using Authentic Cookies:- 

Authentic cookies can be sent by the video player with the request key. This allows the server key to check which user is requesting the key. If the user is not allowed to access the stream, the key will not return back and the user who has proper authentication will receive the decryption key.

3. Using Signed URL(HLS Encryption):-

Signed URLs can be used for providing unique representation to each user. A user-specific representation will then contain a link for the decryption key which will contain an authentication token. The server can then check the authentication token and determine whether the key can be accessed or not.

Is AES-128 protection Safe?

The first question while dealing with video protection is “How safe is this protection?”  AES is a symmetric encryption algorithm that is designed to be efficient in both hardware and software. This algorithm is adopted as the standard encryption algorithm by the U.S. government for encrypting sensitive data. The usage of AES encryption has recently become the part of common encryption and it might be safe to say this level of AES encryption will not able to replace soon.

Which is More Important? FPS or Video Resolution.

What’s supposed to be a nice design feature that adds to the overall impression of a website can turn into a nuisance for visitors if they have to wait for all elements to load and display correctly. one way for optimizing video resolution for web design is to reduce the video’s file size, which will help to drastically improve page load times and playback performance.

However, as each of these factors Frame rate and Video resolution affect the size of the video. Having a high Frame rate and a good Video resolution would increase the size of the video, it may be in the best interest of a web designer to go for both frame rate and resolution so it becomes confusing to understand which one is more important.

Videos are main aspect, used in 90% of sites mainly 34% promotional videos, 31% demonstration videos, 31% demonstration videos, 26 % entertainment videos, 22% news videos, 4% User Generated Content (UGC), 3 Other. It should be optimized with mobile phones as 63% of web surfing is done on Mobiles.[1]…

Why Does Frame Rate Matters?

The term FPS stands for “frames per second” and is also called “frame rate”, referring to both recording and playback speed when talking about video. In regards to shooting, the frames per second measurement are how many frames or images are taken in one second. Frame Rate is the frequency at which the display refreshes. Frame rate options are 24 or 30, 60, 120 and 240. 24 or 30 is determined by the “base frame rate”. 

While it won’t make your image look sharper, it only improves usability and makes animations and effects appear nicer and better on the screen.

Why Does Video Resolution Matters?

Video resolution in a display device refers to the number of distinct pixels that could be displayed in each dimension. It is usually quoted as width× height. The video resolutions you see like 360p, 480p, 720p, or 1080p represent the number of horizontal lines a video has from top to bottom. A 480p video is made up of 480 lines stacked one on top of another, with each line being 852 pixels wide. In other words, a 480p video has a resolution of 852×480 pixels.

For comparison, a 720p HD video has 720 lines that are each 1,280 pixels wide, this means that it is more than twice as sharp as the same video at 480p and can be viewed on a much larger screen.

Conclusion – 

Higher quality video is always the most desirable. As a web designer if I have to go with these two then I will shake hands with the video resolution because while designing a web the video size matters a lot so it’s better to choose a video of higher resolution rather than FPS. A video of lower size and higher resolution will consume less time to load and will provide a great experience to the users.
