Video: Broadcast and OTT monitoring: The challenge of multiple platforms


Is it possible to monitor OTT services to the same standard as traditional broadcast services? How can they be visualised, what are the challenges and what makes monitoring streaming services different?

As with traditional broadcast, some broadcasters outsource the distribution of streaming services to third parties. Whilst this can work well in broadcast, there any channel would be missing out on a huge opportunity if they didn’t also monitor some analytics of the viewer using their streaming service. So, to some extent, a broadcaster always wants to look at the whole chain. Even when the distribution is not outsourced and the OTT system has been developed and is run by the broadcaster, at some point a third party will have to be involved and this is typically the CDN and/or Edge network. A broadcaster would do well to monitor the video provided at all points through the chain including right up to the edge.

The reason for monitoring is to keep viewers happy and, by doing so, reduce churn. When you have analytics from a player telling you something isn’t right, it’s only natural to want too find out what went wrong and to know that, you will need monitoring in your distribution chain. When you have that monitoring, you can be much more pro-active in resolving issues and improve your service overall.

Jeff Herzog from Verizon Digital Media Services explains ways to achieve this and the benefits it can bring. After a primer on HLS streaming, he explains ways to monitor the video itself and also how to monitor everything but the video as a light-touch monitoring solution.

Jeff explains that because HLS is based on playlists and files being available, you can learn a lot about your service just by monitoring these small text files, parsing them and checking that all the files it mentions are available with minimal wait times. By doing this and other tricks, you can successfully gauge how well your service is working without the difficulty of dealing with large volumes of video data. The talk finishes with some examples of what this monitoring can look like in action.

Video: Remote Production In Pajamas

Remote production (AKA REMIs) has been discussed for a long time – but what’s practical today? Teradek, Brandlive and Vimond share their experiences making it work.

The main benefit of remote production is reducing costs by keeping staff at base instead of sending them to the event. Switching video, adding graphics and publishing are all possible in the cloud, but how practical this all is and which people stay behind very much depend on the company; their quality standards, their workflows, complexity of the programme etc.

This panel at the Streaming Media East looks at when remote production is appropriate, how much does a service provider needs to be present, redundancy, the role of standards and is a wide ranging discussion on the topic.

Video: User-Generated HDR is Still Too Hard

HDR and wide colour gamuts are difficult enough in professional settings – how can YouTube get it right with user-generated content?

Steven Robertson from Google explains the difficulties that YouTube has faced in dealing with HDR in both its original productions but also in terms of user generated content (UGC). These difficulties stem from the Dolby PQ way of looking at the world with fixed brightnesses and the ability to go all the way up to 10,000 nits of brightness and also from the world of wider colour gamuts with Display P3 and BT.2020 (WCG).

Viewing conditions have been a challenge right from the beginning of TV but ever more so now with screens of many different shapes and sizes being available with very varied abilities to show brightness and colour. Steven spends some time discussing the difficulty of finding a display suitable for colour grading and previewing your work on – particularly for individual users who are without a large production budget.

Interestingly, we then see that one of the biggest difficulties is in visual perception which makes colours you see after having seen bad colours look much better. HDR can deliver extremely bright and extremely wrong colours. Steven shows real examples from YouTube of where the brain has been tricked into thinking colour and brightness are correct but they clearly are not.

Whilst it’s long been known that HDR and WCG are inextricably linked with human vision, this is a great insight into tackling this at scale and the research that has gone on to bring this under automated control.

Video: Monitoring and Measuring IP Media Networks

nn

The transition from point-to-point SDI based infrastructure to IP essence flows requires a very different approach to fault-finding. Although new IP diagnostic tools are already available on the market, engineers need combined broadcast and IT knowledge to fully understand the flow of video, audio and data across the switching fabric – including packet jitter, latency, and buffer over/underflows causing dropped packets.

In this video Michael Waidson from Tektronix presents methodologies involved in monitoring IP media networks. The following topics are covered:

  • Strategies for choosing IP Address, Port Number and Payload Type for easier identification of the streams
  • Troubleshooting basics (fibres and SFPs types, checking switch ports)
  • PTP synchronisation
  • Checking syntax of decoded streams (Layer 5 RTP, Marker Bit, Payload Type, Sequence Number, Timestamp)
  • Packet transmission (multiple paths, out of order packets in receiver, jitter, PIT Histogram)
  • Timing (reference clock, RTP timestamps, checking PTP lock, PTP and RTP offset, transmission traffic shape models)
