With Amazon, Netflix and so many other VOD services available, broadcasters like the BBC and Discovery are investing a lot in their own VOD services, known as Broadcaster VOD (BVOD) in order to maintain relevance, audiences and revenue.
With this in mind, IBC365 will discuss the business models, platforms and strategies being used by BVOD platforms. They will look at the BBC’s move to build a deep content library of free-to-view box sets, and to the importance of data, personalisation and addressable advertising models.
Further more, this webinar will talk about the commercial and technical requirements to build a BVOD to a standard that’s going to stand on its own in this increasingly crowded, but well-funded marketplace.
Measuring video quality is done daily around the world between two video assets. But what happens when you want to take the aggregate quality of a whole manifest? With VMAF being a well regarded metric, how can we use that in an automatic way to get the overview we need?
In this talk, Nick Chadwick from Mux shares the examples and scripts he’s been using to analyse videos. Starting with an example where everything is equal other than quality, he explains the difficulties in choosing the ‘better’ option when the variables are much less correlated. For instance, Nick also examines the situations where a video is clearly better, but where the benefit is outweighed by the minimal quality benefit and the disproportionately high bitrate requirement.
So with all of this complexity, it feels like comparing manifests may be a complexity too far, particularly where one manifest has 5 renditions, the other only 4. The question being, how do you create an aggregate video quality metric and determine whether that missing rendition is a detriment or a benefit?
Before unveiling the final solution, Nick makes the point of looking at how people are going to be using the service. Depending on the demographic and the devices people tend to use for that service, you will find different consumption ratios for the various parts of the ABR ladder. For instance, some services may see very high usage on 2nd screens which, in this case, may take low-resolution video and also lot of ‘TV’ size renditions at 1080p50 or above with little in between. Similarly other services may seldom ever see the highest resolutions being used, percentage-wise. This shows us that it’s important not only to look at the quality of each rendition but how likely it is to be seen.
To bring these thoughts together into a coherent conclusion, Nick unveils an open-source analyser which takes into account not only the VMAF score and the resolution but also the likely viewership such that we can now start to compare, for a given service, the relative merits of different ABR ladders.
The talk ends with Nick answering questions on the tendency to see jumps between different resolutions – for instance if we over-optimise and only have two renditions, it would be easy to see the switch – how to compare videos of different resolutions and also on his example user data.
It’s very clear that internet streaming is growing, often resulting in a loss of viewership by traditional over-the-air broadcast. This panel explores the progress of IP-delivered TV, the changes in viewing habits this is already prompting and looks at the future impacts on broadcast television as a result.
Speaking at the IABM Theatre at IBC 2019, Ian Nock, chair of IET Media, sets the scene. He highlights stats such as 61% of Dutch viewing being non-linear, DirecTV publicly declaring they ‘have bought their last transponder’ and discusses the full platform OTT services available in the market place now.
To add detail to this, Ian is joined by DVB, the UK’s DTG and Germany’s Television Platform dealing with transformation to IP within Germany. Yvonne Thomas, from the Digital Television Group, takes to the podium first who starts by talking about the youngest part of the population who have a clear tendency to watch streamed services over broadcast compared to other generations. Yvonne talks about research showing UK consumers being willing to have 3 subscriptions to media services which is not in line with the number and fragmented nature of the options. She then finishes with the DTG manifesto for a consolidated and thus simplified way of accessing multiple services.
Peter Siebert from DVB looks at the average viewing time averaged over Europe which shows that the amount of time spent watching linear broadcast is actually staying stable – as is the amount of time spent watching DVDs. He also exposes the fact that the TV itself is still very much the most used device for watching media, even if it’s not RF-delivered. As such, the TV still provides the best quality of video and shared experience. Looking at history to understand the future, Peter shows a graph of cinema popularity before and after the introduction of television. Cinema was, indeed, impacted but importantly it did not die. We are left to conclude that his point is that linear broadcast will similarly not disappear, but simply have a different place in the future.
Finally, head of the panel session, Andre Prahl explains the role of the Deutsche TV-Plattform who are focussing on ‘media over IP’ with respect to delivery of video to end user both in terms of internet bandwidth but also Wi-Fi frequencies within the home.

The important aspects of writing and developing streaming apps aren’t always clear to the beginner and adding video to apps high on the list for many companies. This can be a very simple menu of videos to delivering premium content for paid subscribers. This webinar is perfect for web developers, independent coders, creative agencies, students and anyone who has a basic understanding of programming concepts but little-to-zero knowledge of video development.
In this talk, Bitmovin Developer Evangelist, Andrea Fassina and Technical Product Marketing Manager, Sean McCarthy will share a variety of lessons learned, on topics such as:
What are the most common video app requirements and why?
What are common beginner mistakes with video streaming?
What are the key components of a video streaming service?
How do you measure the quality of a streaming service?
What are some quick tips to quickly improve video experience?
