How to Create a DRM System in VOS Cloud

VOS Cloud offers the possibility to secure the OTT services using DRM. 

Prior configuring the DRM on the services, you must first configure the DRM systems & settings.

This is performed using the 'Scrambling App - DRM systems':

DRM System Name: The name of the configured DRM system.

Requestor ID
: A universally unique identifier (UUID) of the device. The requestor ID must be unique among all devices that connect to the same DRM system.

Encryption Interface: This is the used protocol to interface with the DRM server. You can choose between Widevine and Harmonic KMS. More information on Harmonic KMS, can be found here.

KMS URL: URL of the DRM provider service (you can define a main and a back-up).

Resources: The DRM Resource allows you to configure the following parameters: 

  • Name: Set the name of the configured DRM resource
  • Packaging Type: Choose the targeted packaging (HLS, MPEG-Dash, MSS)
  • Resource ID: This is the resource ID or the asset to be encrypted (also known as Content ID)
You can have several resources per DRM system.

How to Activate DRM on a Multiscreen Service

When using VOS Cloud, you have the possibility to activate content protection on the multi-screen service. This is performed by checking 'Add-on' when creating or modifying the service:

  • Activate the 'DRM' by setting it to ON:

  • Then select the 'DRM system' and 'Resource' for each packaged output

This feature can be activated through the 'Scrambling - DRM Setting':

Packaging Format with DRM Key Rotation Enabled
: Select the targeted standard for the key rotation

Key Rotation Period: Define the key period (in seconds)
