Summary - J.1041 (03/2025) - Digital rights management for video and audio content distribution – System Architecture

Recommendation ITU-T J.1041 is Part 2 of a multi-part deliverable composed of four parts. Part 2 describes the system architecture of digital rights management (DRM) for video and audio content distribution (DRMVACD), including system functional architecture, content encryption mechanism, license format, license acquisition protocol, and DRM server-side architecture, and certificate format.
The service requirements for the application of new generation video and audio technologies, along with the new video service models coupled with a diverse range of consumer devices used for the reception of content, bring new demands and opportunities to the video industry, especially broadcast and television video services, and raise higher requirements for DRM, described in Recommendation ITU-T J.1040. The DRM system not only needs to have well-defined security levels to meet the content protection requirements of different quality and different distribution window periods, but also needs to have sufficient platform compatibility to cover various terminal devices. In addition, higher encryption/decryption efficiency and encryption/decryption modes decoupled from content encapsulation are required to match the rapid development and transformation of video and audio technologies. In addition, an interoperability mechanism is required to achieve a more open DRM ecosystem.
