How does video on demand protect copyright?

Video on demand (VOD) platforms protect copyright through several measures:

  1. Digital Rights Management (DRM): DRM technologies encrypt the video content, making it unreadable without the appropriate decryption key. This ensures that only authorized users can access the content.

    • Example: A VOD platform uses DRM to encrypt a movie. When a user subscribes and tries to watch the movie, the platform verifies their subscription and provides the decryption key to play the movie.

  2. Content Licensing Agreements: VOD platforms obtain licenses from content owners, specifying the terms under which the content can be distributed and accessed. These agreements often include restrictions on usage and copying.

    • Example: A streaming service signs a licensing agreement with a movie studio, allowing it to stream a film for a specified period, with certain limitations on how the film can be used.

  3. User Authentication and Access Control: Platforms require users to log in and may use various methods to verify their identity. Access controls ensure that only authorized users can view specific content.

    • Example: A user must create an account and log in to access a premium movie on a VOD platform. The platform checks their subscription status before granting access.

  4. Watermarking: Some VOD services embed watermarks into the video content, which can help trace unauthorized copies back to the source.

    • Example: A watermark is placed in the corner of a movie streamed on a VOD platform. If someone records and shares this movie, the watermark can identify where it was originally accessed.

  5. Monitoring and Enforcement: VOD platforms actively monitor for copyright infringement and take action against unauthorized distribution or copying.

    • Example: The platform uses automated tools to scan for illegal uploads of its content and works with law enforcement to remove infringing material.

For cloud-based solutions, Tencent Cloud offers services like Tencent Cloud Media Processing Service (MPS), which supports DRM encryption to protect video content. This service allows content providers to securely manage and distribute their videos, ensuring compliance with copyright regulations.
