ISO/IEC 23001-11:2015 specifies metadata for energy-efficient decoding, encoding, presentation, and selection of media.
The metadata for energy-efficient decoding specifies two sets of information: Complexity Metrics (CM) metadata and Decoding Operation Reduction Request (DOR-Req) metadata. A decoder uses CM metadata to vary operatin ## Source - https://isopublicstorageprod.blob.core.windows.net/opendata/_latest/iso_deliverables_metadata/csv/iso_deliverables_metadata.csv Last verified: 2026-08-05.
