Exchange of Live Content
Whether sports, news, or major events, some of the most high value and exciting content in the world is live. The DPP's work includes:
- Recommended profiles for transmission of live video over IP networks. Learn more here.
- Best practices for exchanging live productions online. Learn more here.
- Delivery Requirements for contributing live shows to broadcasters. Learn more here.
Live IP Feeds
When contributing or distributing live content via IP, a huge array of different media coding options exist, along with many stream transport technologies. This variety of options makes the process of sharing content complex and costly.
Recommendation DPP001 Live IP Profiles for contribution and distribution of live content aims to maximise interoperability between parties and simplify their operations, by limiting the number of different profiles in use.
The DPP project group included broadcasters, systems vendors, and streaming technology providers. They defined a range of use-cases based on their business needs, covering audio, SD and HD video, plus some 4K cases. They then developed recommended media coding and streaming profiles, covering transport stream technology across various network types. The scenarios considered included contribution of live video to broadcast centres, and distribution of live video to DTT, DSAT, and OTT delivery platforms.

As business requirements change and technology evolves, new Media and Stream Profiles may be required. We'll continue to develop the profiles, and future releases of the DPP Recommendation will consider 4K UHD, lossless compression, streams for social media platforms, content with varied aspect ratios and digital program insertion into live IP streams.

Live Production Exchange
Traditionally, syndicated feeds for live events have been delivered using costly, managed, cable or satellite feeds. Increasing reliability, security and fault tolerance of IP-based feeds has ensured that distribution using commodity bandwidth is now a viable and cost-effective alternative.
This also allows for a greater level of automation in the process of acquisition, but there is not currently an agreed method for this process, and the associated commercial considerations, to be carried out.
Live Production Exchange is an active DPP project, looking to specify the metadata requirements associated with the publication of these live feeds. Working with a range of member companies, we will deliver a minimum viable product to provide the glue between the acquisition, distribution and reception points.
