25.Common encryption format for ISO BMFF (23001-7)

25.1Topics

25.1.1ISO/IEC 23001-7 2^nd Edition

This format defines a way to encrypt media (audio, video, etc.) in files of the ISO base media file format family. By using a common encryption format, a single media asset can be used by several services and devices using different digital rights management systems, and the implementation complexity that would be consequent on having duplicate files and formats for the same content can be reduced or eliminated.
