Most of this week involved visiting FOSDEM, the Free and Open Source European Developers Meeting, where we were organising the Open Media track in conjunction with colleagues from the EBU and OpenHeadend.

We had an all-hands company meeting in Brussels on the Friday hosted at the lovely Radisson Red Brussels complete with crocodile meat for lunch nearby. Interestingly, the hotel was solar powered from a Tesla PowerPack.

 

During the week, we spent a long time chasing and bisecting a Blackmagic playback bug on very long-running streams that occurred between two driver versions. We also started the number crunching to produce various reports. 

FOSDEM itself had many interesting speakers, but for us the highlight was Gerolf Ziegenhain from the DFS Deutsche Flugsicherung GmbH. This was an incredible insight into how DFS manages Linux and other software that is safety-of-life critical. You would (understandably) think this is a very bureaucratic process but the speaker was able to eloquently explain the mix between the business requirements and the heavy technical knowledge DFS has. For example, they desolder and replace diodes on NVIDIA Graphics cards to improve reliability. Yet at the same time, it takes years of testing to roll out a new software release.

The broadcast industry has a lot to learn from this, many still think that IT hardware can’t be used for mission-critical purposes, yet as I fly to my weekend break in Berlin, it is IT equipment keeping me safe in the skies:

 

So, that didn’t last long...we’ve merged weeks three and four owing to various trips abroad.

We were pleased to attend the European Broadcasting Union Production Technology Seminar (EBU PTS) to hear about how broadcasters are looking forward to Ultra-HD and High Dynamic Range productions in the future, something we are also working on with a number of clients. Day Two culminated in the unique opportunity to watch Planet Earth II in UHD, WCG and HDR using a state of the art projector:

Day three was also very interesting since it was about IP production. We had a standards update about SMPTE 2110 from Wim Vermost. His key point was it must be implementable in software, unlike the current proposals which are heavily skewed to hardware implementations.

In a later session, we also heard from Sky UK about its plans to move its News and Sport MCRs to IP, in what appears to be the first public outing of this project. This ambitious project is something we have been working on with Sky for a while and our encoders/decoders form a significant proportion of the IP connected devices on the network.

The presenter described a workflow we are closely involved in, a reporter speaks at Downing Street, that feed is encoded and transported over IP, it’s then decoded to SMPTE 2022-6 uncompressed IP at the studio and routed as pure-IP.  Furthermore, this is a workflow that is entirely based on standard IT hardware, something industry “commentators” claim to be many years away.

In an unrelated development Sky also announced that it was planning to deliver its channels over IP, a major move for a nearly 30-year old satellite platform. We’ve been working with IPTV pioneers such as Free in France for many years delivering major channels to millions over IP. The technical decisions that Sky take remain to be seen, whether they take a traditional managed IPTV approach or an OTT approach and how this affects the viewer’s experience. Interestingly, the move to IP means that a number of our team can become Sky subscribers for the first time since they aren’t able to have satellite dishes at home.

 

Things we’ve been reading/watching:

Like any New Year’s resolution the difficult part is keeping going especially during London’s freezing wind and rain this week. But nonetheless, here is our Week 2 in review blog:

We believe that over the coming months, we will see more and more broadcasters adopting an IP approach. You can read our opinion on this, and why actually you should be going IT, in CSI Magazine: http://www.csimagazine.com/csi/broadcast-moves-to-IT.php

We started working on our paper and presentation for the NAB Broadcast Engineering and Information Technology Conference (BEITC), which will offer our insights into this field.

We’ve also fulfilled one of our customers’ biggest requests: branded server stickers. These are now available free-of-charge for existing customers and our products will now ship with these.

 

Technical work:

  • • Continued multivendor interoperability testing for SMPTE 2022-6, now extended to testing SD and 720p resolutions. When this will be complete it will be the most detailed analysis of a software based implementation of this standard and its real-world interoperability with numerous hardware implementations.
  • • Continued automated testing of version 1.3 and 1.4 of our decoder
  • • Started evaluating Kaby Lake CPUs from Intel

We were pleased to also be retweeted and liked by some famous British entertainers.

 



Firstly, a warm welcome to 2017! We thought we’d share the weekly goings on here at Open Broadcast Systems, both in our main London office and the rest of our team distributed around Europe.

Globecast SERTE deployment

Our French Partner Ekla Ingeniere installed 2x HD C-100 Decoders at the Globecast SERTE, the main French broadcast switching centre. This decoder has the capability to be software upgraded to 4x simultaneous HD decoders..

We worked with Ekla this week to integrate this unit into SERTE.

Supply Chain Improvements

We might be a software company but we’ve have developed a complex supply chain with parts from dozens of suppliers travelling around the world to numerous systems integrators. Things like customs delays and upstream supplier lead times has at times led to longer lead times than we hoped in 2016. Therefore, at the end of 2016, we started taking steps to reduce lead times, with some units now available within a week of order. In 2017, our goal is for all mainstream chassis to be available within a week.

Technical work

This week, some of our more technical work has included:

  • Continued evaluation of DVB-S2 PCIe boards in our downlink centre
  • Improving performance of 2022-6/7 output
  • Fixing decoder issues in 1.3 release
  • Continued development of automated tests for testing Web/SNMP layer in preparation for 1.4 release

Other Activity

We started planning for our trip to FOSDEM in Brussels at the end of the month.

We have also started planning our NAB booth and demos.

And, of course, the first week of the year means paperwork :(
