DRM (Digital Rights Management) is a set of technologies used to control access to and usage of digital media content. In the context of video streaming, DRM encrypts video files so that only authorized viewers with valid licenses can play them. This prevents unauthorized copying, redistribution, and screen recording of protected content.
How DRM works
DRM protection involves three components: encryption of the video content, a license server that issues decryption keys, and a client-side module (CDM) in the browser or device that handles decryption and playback. The Encrypted Media Extensions (EME) API provides a standard interface between web browsers and DRM systems.
The video content is encrypted during encoding using AES-128 or CBCS encryption
The player requests a license from the DRM server, providing authentication credentials
The license server validates the request and returns decryption keys with usage rules
The browser's CDM (Content Decryption Module) decrypts and renders the video in a protected pipeline
Major DRM systems
Three DRM systems dominate the video industry. Each is tied to specific platforms, so multi-DRM support is required for cross-device compatibility.

Alternatives to full DRM
Full DRM (Widevine, FairPlay) requires complex infrastructure and licensing agreements. For many use cases, lighter protection mechanisms provide sufficient security at lower cost and complexity.
Signed URLs: time-limited, tamper-proof links that expire after a set duration
Domain restrictions: videos can only be embedded on authorized domains
Token authentication: viewers must present a valid session token to access content
Geo-blocking: restrict access based on the viewer's geographic location
Watermarking: invisible forensic marks to trace leaks to specific viewers
How Videas protects your content
Videas provides multiple layers of content protection without requiring complex DRM setup. Every video is delivered via signed URLs that are unique per viewer session and expire after a configurable duration. Domain restriction ensures your embedded player only works on authorized websites. For monetized content on Videas Channels, additional access controls enforce subscription and purchase requirements before granting playback access.
DRM stands for Digital Rights Management. It refers to encryption-based technologies that prevent unauthorized access, copying, and redistribution of video content.
Videas uses signed URLs, domain restrictions, and token-based authentication to protect content. These mechanisms provide strong protection for most use cases without the complexity and cost of full DRM licensing.
Not necessarily. Many successful VOD platforms use signed URLs and domain restrictions rather than full DRM. The right level of protection depends on the value of the content and the acceptable level of risk.
