Video: HDR Formats and Trends

As HDR continues its slow march into use, its different forms both in broadcast and streaming can be hard to keep track of and even differentiate. This talk from the Seattle Video Tech meetup aims to tease out these details.

Brian Alvarez from Aamzon Prime Video starts with a very brief look at how HDR has been created to sit on top of the existing distribution formats: HLS, DASH, HEVC, VP9, AV1, ATSC 3.0 and DVB. The way it does this is in a form based on either HLG or PQ.

Brian takes some time to discuss the differences between the two approaches to HDR. First off, he looks at HLG which is an ARIB standard freely available, though still with licencing. This standard is, technically, backwards compatible with SDR but most importantly doesn’t require metadata which is a big benefit in the live environment and simplifies broadcast. PQ, then, is next when we hear about the differences in approach from HLG and suggests that this gives better visual peformance than HLG. In the PQ ecosystem, Brian works through the many standards explaining how they differ and we see that the main differences are in in colour space and bit-depth.

The next part of the talk looks at the, now famous, venn diagrams showing which copmanies/products support each variant of HDR. This allows us to visualise and understand the adoption of HDR10 vs HLG for instance, to see how much broadcast TV is in PQ and HLG, to see how the film industry is producing exclusively in PQ and much more. Brian comments and gives context to each of the scenarios as he goes.

Finally a Q&A session talks about displays, end-to-end metadata flow, whether customers can tell the difference, the drive for HDR adoption and a discussion on monitors for grading HDR.

Video: How the BBC Built a Massive Media Pipeline Using Microservices

The BBC iPlayer is the biggest audio and video-on-demand service in the UK. It receives 10 million video playback requests every day and the service publishes over 10,000 hours of media every week.

Moving iPlayer to the cloud has enabled the BBC to shorten the time-to-market of content from 10 hours to 15 minutes.

In this session, the BBC’s lead architect, Stephen Godwin, describes the approach behind creating iPlayer architecture, which uses Amazon SQS and Amazon SNS in several ways to improve elasticity, reliability, and maintainability. You see how BBC uses AWS messaging to choreograph the 200 microservices in the iPlayer pipeline, maintain data consistency as media traverses the pipeline, and refresh caches to ensure timely delivery of media to users.

This is a rare opportunity to see the internal workings and best practices of one of the largest on-demand content delivery systems operating today.
