Overview

Content Protection for broadcasters and multimedia delivery is highly important for protecting Intellectual property. This course examines the technical architecture of Digital Rights Management (DRM) systems used by broadcasters and for Internet delivered Multimedia Service in a practical engineering environment. It identifies the objectives and key techniques necessary for successful system implementation, examines the architectures used by the major commercial systems and compares the functions of each.

The course will examine the typical server functions that are responsible for providing the licenses to users and for serving the keys. It will compare and contrast the main DRM technologies (Microsoft PlayReady, Google Widevine, Apple FairPlay, Adobe Primetime, Marlin MS3) and identify which player platforms are supported. Practical implementation of DRM within players will be considered and the mechanisms for troubleshooting studied.

Many service providers do not wish to produce different encoded and encrypted versions of content for playing on a variety of different systems. The course will therefore provide a solution using Common Encryption (CENC) with multiple License servers. The course will also look at how these techniques can be implemented in practice on a player deployed for MPEG-DASH delivered content.

Objectives

Upon completion candidates will be able to:

  • Identify the functions of Digital Rights Management systems

  • Compare cryptographic techniques employed in DRM to identify strengths and weaknesses

  • Analyse building blocks of a generic DRM system

  • Identify how Common Encryption can be deployed in multi-DRM environments

  • Compare options for Player Technologies on multiple platforms

  • Compare rights expression languages and determine how rights can be defined

  • Describe different Digital Rights Management servers needed in a full service

  • Compare Microsoft PlayReady, Google Widevine, Apple FairPlay, Adobe Primetime and Marlin MS3 DRM systems

Target Audience

Project Managers, Systems Engineers, Systems Integrators, Developers and service delivery engineers who have and interest in learning about the security of Multimedia content over an IP network.

Additional Information

The course will be available for delivery either on-site or at a Public course location. Attendance in person to the site of the course is always the preferred option. However where this is not possible students may connect to the execution via Citrix GoToTraining whether the course is running on-site or at a public location subject to good enough Internet services being provided at the host site.
