Video: Tech Talk: Production case studies – the gain after the pain

Technology has always been harnessed to improve, change and reinvent production. Automated cameras, LED walls, AR, LED lighting among many other technologies have all enabled productions to be done differently creating new styles and even types of programming.

In this Tech Talk from IBC 2019, we look at disruptive new technologies that change production, explained by the people who are implementing them and pushing the methods forward.

TV2 Norway’s Kjell Ove Skarsbø explains how they have developed a complete IP production flow and playout facility. This system allows them more flexibility and scalability. They did this by creating their own ESB (Enterprise Service Bus) to decouple the equipment from direct integrations. Working in an agile fashion, they delivered incremental improvements. This means that Provys, Mayam, Viz, Mediator amongst other equipment communicate with each other by delivering messages in to a system framework which passes messages on their behalf in a standard format.

Importantly, Kjell shares with us some mistakes that were made on the way. For instance, the difficulties of the size of the project, the importance of programmers understanding broadcast. “Make no compromise” is one of the lessons learnt which he discusses.

Olie Baumann from MediaKind presents live 360º video delivery, “Experiences that people have in VR embed themselves more like memories than experiences like television” he explains. Olie starts. by explaining the lay of the land in today’s VR equipment landscape then looking at some of the applications of 360º video such as looking around from an on-car camera in racing.

Olie talks us through a case study where he worked with Tiledmedia to deliver an 8K viewport which is delivered in full resolution only in the direction the 360º viewer and a lower resolution for the rest. When moving your head, the area in full resolution moves to match. We then look through the system diagram to understand which parts are in the cloud and what happens.

Matthew Brooks with Thomas Preece from BBC R&D explain their work in taking Object-based media from the research environment into mainstream production. This work allows productions to deliver object-based media meaning that the receiving device can display the objects in the best way for the display. In today’s world of second screens, screen sizes vary and small screens can benefit from larger, or less, text. It also allows for interactivity where programmes fork and can adapt to the viewers tastes, opinions and/or choices. Finally, they have delivered a tool to help productions manage this themselves and they can even make a linear version of the programme to maximise the value gained out of the time and effort spent in creating these unique productions.

Video: Analysis of emerging video codecs: coding tools, compression efficiency and complexity

There continues to be fervent activity in codec development and it’s widely expected that there won’t be a single successor to AVC (h.264). Vying for one of the spots is AV1 but also MPEG’s VVC.

In this talk at SMPTE 2018, Julien Le Tanou from MediaKind compares the coding tools used by VVC and AV1 and explains the methodology he uses to compare the two codecs. We see the increase in decoding time compared to HEVC required for VVC as well as the famously slow AV1. We also see the bitrate savings with VVC performing better.

Julien also presents subjective results which are not correlated to the objective results and explains reasons for this.

Video: OTT Moves Toward Microservices


 

Using microservices is a way of architecting your software platform to be nimble, simple and is just as applicable to on-premise platforms as cloud. As scaling is important for OTT providers, it’s not surprising that much work is being done in the OTT sector to utilise microservice architectures.

Even companies that are not yet actively operating on a microservices architecture are looking for vendors who at least have a strategy to cater to it for the future. This session will examine the core benefits (including redundancy, dev ops, scalability, and self-healing), the different approaches (including containerisation and orchestration via Docker, Kubernetes, and Mesos, as well as native microservices models like Erlang), and the complexities of migrating a generic architecture to a microservices architecture.

This panel covers:

    • Why is OTT so suited to microservices?
    • How microservices enable companies to be flexible to changing customer demands
    • How microservices reduce complexity
    • Benefits of continuous deployment

plus much more!

Video: SRT – Achieving Low-Latency, Reliable, Video Streaming over Public Networks

Real-life use cases on this innovative Open Source technology from the SRT Alliance recorded at IBC 2018.

SRT, Secure Reliable Transport, is an open source video transport protocol and technology stack that optimises streaming performance across unpredictable networks with secure streams and easy firewall traversal, bringing the best quality live video over the worst networks.

The SRT Open Source project, driven by the SRT Alliance, is a collaborative community of industry leaders and developers striving to achieve lower latency internet video transport by continuously improving open-source SRT.

At the end of the day, a technology is only as good as what it can actually do rather than what people promise and, in this talk, there are only real-world case studies from major companies. Including some brief words from Microsoft Azure’s Satish Annapureddy discussing Microsoft’s recent membership of the SRT alliance.
