Question 1

Is AES encryption the same as DRM?

Accepted Answer

No. AES is the cipher that scrambles the video. DRM is the system that decides who gets the AES key, on which device and under what rules. Modern DRM still uses AES under the hood, so think of DRM as a governance layer sitting on top of AES, not something that replaces it.

Question 2

Is HLS AES-128 secure enough for paid content?

Accepted Answer

The encryption itself is strong. The problem is the key gets delivered to the client as a file, and a determined viewer can pull it out and rebuild a decrypted copy. Token-protected, expiring keys will deter casual ripping, but most studios and licensors won't accept plain AES for premium content, full stop. If you're carrying a paid or licensed catalogue, use multi-DRM.

Question 3

Why is single-DRM usually not enough?

Accepted Answer

Because each DRM only covers part of the device universe. FairPlay doesn't run on Chrome or Android. Widevine doesn't run in Safari on iOS. Go single-DRM and protected content simply won't play for anyone outside that one ecosystem, which is why most commercial services end up needing multi-DRM for full coverage anyway.

Question 4

What is multi-DRM exactly?

Accepted Answer

You package your content once with Common Encryption (CENC) and serve the correct license per platform through Widevine, FairPlay or PlayReady, all routed through Encrypted Media Extensions. One protected asset, and it reaches every major browser, phone, smart TV and console with whatever DRM that platform actually supports.

Question 5

Does multi-DRM stop all piracy?

Accepted Answer

Nothing stops all piracy. But multi-DRM paired with hardware security levels, Widevine L1 and FairPlay in particular, makes ripping genuinely difficult, adds HDCP output protection, and lets you enforce expiry, device binding and revocation. It's the highest practical bar you can set for streaming, and it's the level studios expect to see.

Question 6

Do I have to build the three license servers myself?

Accepted Answer

Not if you're on a managed platform. Doing it yourself means integrating Widevine, FairPlay and PlayReady license flows, building out CENC packaging and testing on real devices across every platform. Flicknexs bakes multi-DRM into the white-label platform, so you configure the policy and the platform handles packaging, licensing and player integration.
