VOD (Video on Demand)

VOD (video on demand) is pre-recorded video that viewers can start watching whenever they choose, as opposed to scheduled live broadcast. Courses, film catalogs, and membership libraries are VOD. Protecting VOD means encrypting a stored catalog with DRM and controlling access, since the files persist and can be repeatedly targeted.

What is VOD?

VOD (video on demand) is pre-recorded video that viewers can start whenever they want, in contrast to live streaming that follows a schedule. Course libraries, film and series catalogs, and membership content are all VOD.

How VOD Differs from Live

VOD content is encoded, stored, and served on request, so viewers can pause, rewind, and rewatch. Because the files persist in a catalog, they can be targeted repeatedly by download and ripping attempts, which makes durable protection important.

Protecting VOD

  • DRM on the catalog: Encrypt stored renditions so downloads are useless without licenses.
  • Access control: Token or OTP playback ties each view to an entitled viewer.
  • Watermarking: Deters and traces screen recording of on-demand content.

For Platform Owners

Most course, EdTech, and membership businesses are primarily VOD. Their protection priorities are DRM, watermarking, and access control across a persistent library, plus secure offline downloads where viewers watch on the move.
