Webinar: Transforming creative workflows: Making great content in the cloud

Posted on 18th April 2019 by Russell Trafford-Jones

Join IBC365 on Thursday 25 April at 4pm BST to explore why creators are turning to cloud to transform the way they make great content and how virtualised workflows are unlocking the ability to work in new ways: faster, more collaborative, more efficient and more creative.

This webinar goes inside some of the world’s leading content creators, production and post-production operations to hear how they are embracing cloud technology to transform the creative processes used to make, produce and deliver video.

The webinar will cover ways in which cloud is enabling more collaboration, access to more talent, round-the-clock working, more content security, and slicker workflows. There’s also a dose of reality, as the human and technology challenges and the potential pitfalls of virtualising creative workflows are explored.

Case studies focus on using cloud for:
•Streamlining content creation in the field
•Transforming production and post-production processes
•Efficient content delivery and backhaul

Video: Power Talks – ATSC 3.0

Posted on 17th April 2019 by Russell Trafford-Jones

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: 2019 Display Trends and Hot Display Apps

Posted on 16th April 2019 by Russell Trafford-Jones

Display technology has always been deeply intertwined with broadcasting. After all, when John Logie Baird first demonstrated his working television, he had to invent both the camera and the display device, then known as at the televisor. He himself worked tirelessly on improving television and less than 20 years after his black and white debut was working on a colour television which used two CRT (Cathode Ray Tubes) to produce its picture culminating in the world’s first demonstration of a colour TV in 1944 – incidentally discovering, demonstrating and patenting 3D TV on the way!

So it is today that the displays define what we can show to viewers. Is there any point in mastering a video to show at 10,000 NITs if there is no display that can show something so bright? Pushing all of Europe and the US’s television programmes to 8K resolution is of limited benefit when 8K TVs are in limited supply and in few homes.

This talk looks at the state of the art of display technology seeing where it’s being used and how. Digital Signage is covered and of course this is where the high brightness technology is developed, for signs outside, some of which could influence more conventional TVs on which we want to watch HDR (High Dynamic Range) video.

When OLED technology first came along it was quickly slated as a great option TVs and yet all these years later we see that its adoption in large panels is low. This shows the difficulty, sometimes, in dealing with the technical challenges of great technologies. We now see OLEDs in wearable devices and smaller screens. The number of the screens is quickly increasing as IoT devices, watches and other electronics start to adopt full screens instead of just flashing LEDs. This increase in manufacturing should lead to renewed investment in this field potentially allowing OLEDs to be incorporated in to full-sized, large TVs.

The talk finished with a look at the TV market covering quantum dots and what people really mean when they mention ‘LED TVs’.

This webinar is from the Society for Information Display and is produced in partnership with SMPTE.

Video: Making Video Streams QUICer

Posted on 15th April 2019 by Russell Trafford-Jones

There are many ways to speed up live streaming and much work has gone in to reducing chunk lengths for HLS-style streaming, WebRTC has arrived on the scene and techniques to speed up chunk delivery are in production in CDNs around the world.

But we shouldn’t forget lower down in the detail, we have how the web sites are actually saved to customers – the venerable HTTP. Running on TCP/IP, HTTP packets are delivered using very thorough acknowledgement mechanisms within TCP/IP. Furthermore, it’s immune to spoofing attacks due to a three way handshake to set up the connection.

However, all this communication ads latency as even for low latency connections, these communications can add up to a significant latency and affect the speed of the throughout of the connection.

This talk introduces QUIC which is a replacement for HTTP developed by Google which uses UDP as its underlying delivery mechanism, thus avoiding much of this built-in two way comms.

At the Mile High Video event, Miroslav Ponec from Akamai introduces this protocol which is undergoing standardisation at the IETF explaining how it works and why it’s such a good idea.
