DPP Document Formats

As part of our aim to deliver a simpler and more effective global content supply chain, we publish a range of DPP technical documents.

DPP Published Documents

Each DPP document strand serves a specific purpose, with a defined governance model.

A DPP Recommendation is a normative document that defines specific technical parameters. It sets out to meet a defined set of business requirements with a technical solution. Implementers of a DPP Recommendation are expected to implement it in full. In line with many other organisations (such as W3C, EBU, ITU), we chose the name Recommendation.

DPP Guidance documents are informative, offering supporting information, guidelines, or suggested implementation parameters. They may include technical details, but they are usually suggestions rather than requirements. Implementers of a DPP Guidance document are free to choose which elements to implement.

DPP Business Requirements documents outline a set of business requirements, collected from our member companies and/or the wider industry. They are most likely to be published before work begins on a Recommendation or Guidance document, as they set the framework of requirements that subsequent document will fulfil.

DPP Delivery Requirements are template documents which can be used by content providers who commission content, to define their own delivery requirements. They are designed in line with DPP Recommendations or specifications such as AMWA AS-11 and SMPTE TSP 2121.

Governance

DPP documents using the above formats undergo a formal governance and approval process. The process begins with a working group made up of interested DPP members, who work on the document. This is followed by review by a stakeholder group, a broader group of interested DPP members. Any DPP member may request to join the stakeholder group for topics that interest them, by contacting the DPP team members listed on each individual project web page, or by contacting Head of Delivery and Growth, Rowan de Pomerai.

The document approval process is as follows:

  1. DPP working group prepares a draft.
  2. The working group chair and DPP project lead review the document with the working group and agree when to elevate the document to the stakeholder group.
  3. The topic is added to the agenda for the next stakeholder group meeting.
  4. The document is discussed at the stakeholder group meeting.
  5. The Stakeholder Group is invited to take part in a 2-week review period.
  6. Comments are submitted to the working group chair and DPP project lead, who make minor changes where necessary.
  7. If any of the feedback is substantive enough to require a redraft, the process begins again.
  8. If no substantive change is required, the Chair and DPP project lead propose the final document to the Head of Delivery and Growth for approval.
