Content Delivery

Content Delivery

Since its inception, the DPP has worked to make the exchange of content and metadata in the supply chain more seamless.

We've worked on important standards and specifications like AS-11 and IMF. We've defined metadata sets to help interoperability in specific use cases. And we've worked on recommendations for the exchange of live content.

We've also delivered outputs that help with ensuring that the process of content exchange is as smooth as possible:

Supplying the VOD Revolution

In 2020, the DPP published an in-depth analysis of the workflows and formats involved in delivering content to VOD platforms.

With a lack of commonality between organisations, it unearthed a picture of chaos, complexity, and inefficiency. However, a clear path to a more efficient future also emerged, leading to publications like Guidance DPP007 Content Supplier Onboarding and Recommendation DPP008 Business to Business Metadata Exchange.

Supplying the VOD Revolution

An extensive piece of research into the global supply of content to VOD platforms, Supplying the VOD Revolution defines a reference workflow for the supply of content from distributors and aggregators to platforms. It exposes the pain points felt by implementers of these workflows, and explores the web of standards and formats in use today. The report also asks: What practical steps can be taken to reduce complexity and enhance efficiency in this vital artery of our industry?

Onboarding

When a content distributor delivers content to a platform, the two organisations must first complete a process of onboarding to set up and test the workflows and technology.

Onboarding is a multi-step process requiring the distributor to build multiple profiles, create & validate test files, and configure automated systems. These steps are not always clearly defined, leading to mis-communication and delays.

Based on the input of major VOD platforms, content producers, and distributors, we published Guidance DPP007: Best Practices for Content Supplier Onboarding.

DPP007 - Content Supplier Onboarding

A successful onboarding process ensures content and data are shared efficiently between sender and receiver.


This guidance sets out commonly agreed best practices that are simple to implement and can drive significant time and cost savings.


It is recommended reading for both senders and receivers of VOD content.

Delivery to UK Broadcasters

Since 1st October 2014, UK broadcasters have accepted files using the AMWA AS-11 DPP file format. Each broadcaster's delivery requirements are based on a common DPP template document, with a live delivery template also available. Finally, a series of supplements provides additional information, including additional advice on Metadata, HDR, Surround Sound, 3D and Super16.

UHD Delivery

The current DPP delivery templates specify AS-11 X1 for UHD programme delivery, however some broadcasters have chosen to move to IMF as a preferred alternative. With this in mind, we are in the process of authoring a new template for UHD delivery, based on IMF Application DPP (ProRes), as specified in SMPTE RDD 59-1. We are currently working with the broadcasters to specify the scope of such a document, and will release it for use later in 2022.

Broadcaster delivery requirements

The delivery requirements for each UK broadcaster are available here:

Delivery Requirements: BBC

Delivery Requirements: ITV

Delivery Requirements: Channel 4

Delivery Requirements: Channel 5

Delivery Requirements: Sky

Delivery Requirements: BT Sport

Delivery Requirements: TG4

DPP template delivery requirements

Each broadcaster's delivery requirements are based on the common DPP template. The latest versions of these are as follows:

DPP AS-11 File Delivery Requirements [Template]

This document outlines the technical requirements for the delivery of programmes using the AMWA AS-11 DPP file format.

DPP Live Delivery Requirements [Template]

This document outlines the technical requirements for the delivery of Live programmes to UK broadcasters.

Supplements

A series of supplements give additional advice on PSE, HDR, Surround Sound, 3D, and Super16:

DPP Supplement - PSE Devices

Supplement for HDR

Supplement for Surround Sound

Supplement for Super16mm

Commercials and Promotions

Just as with programme delivery, it’s important to have common specifications for delivery of short-form content, such as Commercials, Sponsorship and Promotional material.

UK HD Commercials, Sponsorship, Promotions, and Presentation Events

Historically in the UK, each broadcaster used their own specifications for the delivery of Commercials and Sponsorship. A unified DPP delivery specification is now available, alongside an equivalent for Promotions and Presentation Events.

UK HD Commercials and Sponsorship [Template]

This document outlines the technical requirements for the delivery of HD Commercials and Sponsorship material to UK broadcasters.

UK HD Promos and Presentation [Template]

This document outlines the technical requirements for the delivery of HD Promotions and Presentation material to UK broadcasters.

AMWA AS-11 X5 and X6

AS-11 X6 has now been published by the AMWA and is in production use by broadcasters. The specification was defined by DPP members to facilitate delivery of air-ready video for short form content such as advertisements, promos, and music videos.

It is based on AVC-i 100 at 1080i50 and provides:

  • embedded subtitles (IMSC1.1 or OP-47)
  • advert-specific metadata
  • metadata for music videos

A corresponding draft specification exists for UHD resolutions: AS-11 X5. It is ready to be finalised whenever one of our members decides to receive deliveries in UHD.
