DPP Metadata

The Digital Production Partnership (DPP) is an initiative by UK public broadcasters to develop a common exchange format for television programs. The DPP defines an XML schema containing the technical and descriptive metadata for a program.

The Advanced Media Workflow Association (AMWA) created the AS-11 specification which defines a constrained MXF format used for program delivery. DPP metadata is embedded within an AS-11 MXF file.

Use the UkDppProgrammeInput property to identify a DPP XML input file. For example the following API request inserts DPP metadata into an AS-11 output:
