Webinar: HDR Dynamic Mapping

HDR broadcast is on the rise, as we saw from the increased number of ways to watch this week’s Super Bowl in HDR, but SDR will be with us for a long time. Not only will services have to move seamlessly between SDR and HDR services, but there is a technique that allows HDR itself to be dynamically adjusted to better match the display its on.

Introduced in July 2019, content can now be more accurately represented on any specific display, particularly lower end TVs. Dynamic Mapping (DM), is applies to PQ-10 which is the 10-bit version of Dolby’s Perceptual Quantizer HDR format standardised under SMPTE ST-2084. Because HLG (ARIB STV-B67) works differently, it doesn’t need dynamic mapping. Dynamic Metadata to support this function is defined as SMPTE ST 2094-10, -40 and also as part of ETSI TS 103 433-2.

Stitching all of this together and helping us navigate delivering the best HDR is Dolby’s Jason Power and Virginie Drugeon from Panasonic in this webinar organised by DVB.

Video: The End of Broadcast? Broadcast to IP Impacts

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.

Webinar: DVB-I service discovery and programme metadata

DVB-I is an initiative to develop technical standards for television to be delivered over IP, whether over-the-top or over the internet. DVB-I works with DVB-T (terrestrial), DVB-S (satellite) and DVB-C (cable) broadcast standards so accessing services feels the same whichever delivery channel is used.

DVB-I makes the best use of the different capabilities of each channel:
– People who don’t have broadcast television can still receive services
– Devices that don’t include DVB tuners can still receive services
– New services are possible which wouldn’t be possible on conventional broadcast platforms

There are many separate ways of achieving a hybrid of OTT-delivered and broadcast-delivered content, but they are not necessarily interoperable. DVB aims to solve the interoperability issue, along with the problem of service discovery with DVB-I. As the internet is global, also DVB-I will allow global distribution of programming, whilst still honouring licensing agreements and regulatory requirements.

This webinar from DVB will cover what DVB-I is, the key use cases, it’s current status and the future timeline. The webinar will also look at service discovery, service lists and end by discussing programme metadata.

You can look at the current approved DVB-I standard here.

Video: HbbTV and ATSC 3.0 sees broadcasters striking back

Should HbbTV and ATSC 3.0 be seen as the last flailing attempts for over-the-air broadcasters to remain relevant, or an important step forward in terms of keeping in step with changing viewership? Both technologies enable traditional broadcast to be mixed with internet-based video, entertainment and services as part of one, seamless, experience.

ATSC 3.0 has taken hold in the US and some other countries as a way to deliver digital video within a single traditional VHF channel – and with the latest 3.0 version, this actually moves to broadcasting IP packets over the air. HbbTV, on the other hand, is more commonly found in Europe and Asia with deployments in nearly 40 countries.

ATSC 3.0 is ready for deployment in the US and is now at a turning poin. With a number of successful trials under its belt, it’s now time for the real deployments to start. In this panel discussion as part of the IBC 2019 conference we hear that CES 2020 will be the time to listen out for major ATSC announcements.

The approach to digital TV in most other places, through DVB, is to bring together many broadcasters in to one multiplexed signal. In the initial iterations of DVB-T, broadcasters have banded together under the same name: In the UK and Australia, for instance, it’s ‘Freeview’. So when moving to something like HbbTV, in contrast to the ATSC plan, it’s natural to do the same.

This panel brings together companies who are pushing the technologies forward from the Europe and the US.
