Video: TR-1001 Replacing Video By Spreadsheet

Here to kill the idea of SDNs – Spreadsheet Defined Networks – is TR-1001 which defines ways to implement IP-based media facilities avoiding some typical mistakes and easing the support burden.

From the JT-NM (Joint Taskforce – Networked Media), TR-1001 promises to be a very useful document for companies implementing ST-2110 or any video-over-IP network Explaining what’s in it is EEG’s Bill McLaughlin at the VSF’s IP Showcase at NAB.

This isn’t the first time we’ve written about TR-1001 at The Broadcast Knowledge. Previously, Imagine’s John Mailhot has dived in deep as part of a SMPTE standards webcast. Here, Bill takes a lighter approach to get over the main aims of the document and adds details about recent testing which happened across several vendors.

Bill looks at the typical issues that people find when initially implementing a system with ST-2110 devices and summarises the ways in which TR-1001 mitigates these problems. The aim here is to enable, at least in theory, many nodes to be configured in an automatic and self-documenting way.

Bill explains that TR-1001 covers timing, discovery and connection of devices plus some of configuration and monitoring. As we would expect, ST-2110 itself defines the media transport and also some of the timing. Work is still to be done to help TR-1001 address security aspects.

Video: Monetization with Manifest Manipulation

Manipulating the manifest of streamed video allows localisation of adverts with the option of per-client customisation. This results in better monetisation but also a better way to deal with blackouts and other regulatory or legal restrictions.

Using the fact that most streamed video is delivered by using a playlist which is simply a text file which lists the locations of the many files which contain the video, we see that you could deliver different playlists to clients in different locations – detected via geolocating the IP address. Similarly different ads can be delivered depending on the type of client requesting – phone, tablet, computer etc.

Here, Imagine’s Yuval Fisher starts by reminding us how online streaming typically works using HLS as an example. He then leads us through the possibilities of manifest manipulation. One interesting idea is using this to remove hardware delivering cost savings using the same infrastructure to deliver to both the internet and broadcast. Yuval finshes up with a list of “Dos and Don’ts” to explain the best way to achieve the playlist manipulation.

Sarah Foss rounds off the presentation explaining how manifest manipulation sits at the centre of the rest of the ad-delivery system.

Video: Power Talks – ATSC 3.0

ATSC 3.0 is the major next step in broadcasting for the US, South Korea and other countries and is a major update to the ATSC standard in so many way that getting across it all is not trivial. All terrestrial broadcasting in the US are done with ATSC as opposed to many other places, including Europe, which use DVB.

ATSC 3.0 brings in OFDM modulation which is a tried and tested technology also used in DVB. But the biggest change in the standard is that all of the transport within ATSC is IP. Broadcasters now, using broadband as a return path, have two-way communication with their viewers allowing transfer of data as well as media.

In this talk from Imagine Communications, we talk a look into the standard which, as is common nowadays, is a suite of standards. These standards cover Early Alerts, immersive audio, DRM, return paths and more. We then have a look at the system architecture of the ATSC 3.0 broadcast deployed in Phoenix.

South Korea has been pushing forward ATSC 3.0 and Chet Dagit looks at what they have been doing and how they’ve created high quality UHD channels to the consumer. He then looks at what the US can learn from this work but also DVB deployments in Europe.

Finally, Yuval Fisher looks at how the data and granularity available in ATSC 3.0 allows for more targeted ads and how you would manage both internally and harnessing it for ad campaigns.

Video: Building Large SMPTE ST 2110 Systems Using JT-NM TR-1001-1

With the SMPTE 2110 suite of standards largely published and the related AMWA IS-04 and -05 specifications stable, people’s minds are turning to how to implement all these standards bringing them together into a complete working system.

The JT-NM TR-1001-1 is a technical recommendation document which describes a way of documenting how the system will work – for instance how do new devices on the network start up? How do they know what PTP domain is in use on the network?

John Mailhot starts by giving an overview of the standards and documents available, showing which ones are published and which are still in progress. He then looks at each of them in turn to summarise its use on the network and how it fits in to the system as a whole.

Once the groundwork is laid, we see how the JT-NM working group have looked at 5 major behaviours and what they have recommended for making them work in a scalable way. These cover things like DNS discovery, automated multicast address allocation and other considerations.
