Currently, this requires two sets of files, one for HLS and one for DASH, though this will change over the next few years (more on this below). That’s because you’ll need HLS to reach Apple devices in the browser, and you’ll need DASH for most other devices. By way of background, all the DRM tools we’ll discuss will be implemented within either the HTTP Live Streaming (HLS) or Dynamic Adaptive Streaming over HTTP (DASH) architectures, though many producers will need to support both. Second, whoever has the decryption key can decrypt the video there’s no additional authorization between player and server to verify that the viewer should be able to watch the video. First, at some point during the retrieval of the decryption key, it’s available in the browser cache, where it can be easily be grabbed. There are two major problems with this approach. Simple encryption protects the key via HTTPS. In this schema, access to the keys would only be available to members or employees who have access to protected content in the HTTPS site.įigure 1. Simultaneously, the browser seeks to retrieve a decryption key from the location specified in the manifest file, typically from an HTTPS server so you can require authorization before the key is downloaded. During playback, the player clicks the link with the content and starts the download, often from an HTTP server (see Figure 1). To deploy AES 128-bit encryption, you encrypt your content during packaging. Since simple encryption is both cheaper and easier than true DRM, it’s a useful distinction to understand, so let’s start there. This concept of third-party DRM platforms is one of the key features that separates true DRM from simple encryption like what’s available for HLS via AES 128-bit encryption.

In this tutorial, we’ll describe what DRM is, how it works, which DRM technologies you’ll need to implement, how to choose a technology partner, how to encrypt, and how to license acquisition to your video player. Perhaps it’s to protect premium content that you’re selling, or perhaps to control access to training, marketing, sales, on-boarding, or other proprietary or confidential videos. You’ve been distributing unsecured video from your website, and you’ve decided that you need content protection in the form of digital rights management (DRM).
