Webinar: Women in Technology: Now and in the Future

Posted on 26th February 2019 by Russell Trafford-Jones

Date: Wednesday 27th February 2019
12:30 PM EST / 9:30 AM PST / 17:30 GMT

Ofcom recently surveyed the 5 main UK broadcasters and found that women held only 25% of technical roles and so the report shines more light on a problem we all live with in this and many other industries. Pleasingly there are noticeable and increasing steps of late to actively counter the gender imbalance when it comes to workplace diversity.

More can always be done, but recent, successful, steps by IBC to even out male/female representation in the conference speakers is one example of taking concrete steps to ensure that the women who are in the industry are heard and seen. Fortunately IBC is not alone in this and many trade shows across industries have taken positive steps and, at the very least, included Women in Technology sessions in their agenda.

This webcast brought to you by SMPTE and SID, the Society for Information Display, looks at:
• Why Women in Technology activities are becoming more important in the high tech industry;
• How the display industry does in terms of diversity;
• What is next for the industry and how can women contribute to its success.

Video: RIST – an evolutionary video transport protocol

Posted on 25th February 2019 by Russell Trafford-Jones

Delivering low-latency live-video over the public internet, or any network which sees packet loss is ever a challenge, but recently there have been a number of protocols which have been created to allow this to work.

The problem to be fixed is that packets get lost and when you have a video decoder trying to output 50 images every second, there really isn’t time to deal with missing packets. Protocols such as SRT, Zixi and, now, RIST allow a mechanism which adds a small buffer and a mechanism to request missing data.

This isn’t a problem, in general, for live streaming to consumers on devices or computers such as Netflix or iPlayer because they use HLS or similar protocols based on TCP, but for low-latency streams this is not practical.

In this talk Kieran Kunhya explains more about these basics, the challenges to be overcome and the ways of dealing with them.

He covers:

UDP & TCP.
RIST and other similar protocols
Retransmissions
Negative Acknowledgements
Implementations of RIST
Future plans for RIST

Video: Scalable Video Coding in HEVC & AV1

Posted on 22nd February 2019 by Russell Trafford-Jones

While it has never played a big role in practical applications, scalable video coding has been around since the times of MPEG 2, and might actually have some advantages over the multi-rate transmission often applied today. The purpose of scalable coding is to efficiently compress multiple different versions of the same video in one “scalable” bitstream. Actually this sounds like the perfect solution for VOD and streaming applications, but unfortunately it has some downsides and few vendors ever used it. In this talk, Chrstian will review the basic idea of scalable coding, how it is enabled in modern coding standards and the pros and cons of implementing the technology in streaming applications.

Webinar: Build Your Own Video Workflows Using the Latest AWS Solutions

Posted on 21st February 2019 by Russell Trafford-Jones

Date: February 27, 2019 at 8am PT / 4pm GMT and a second session at 10am IST / 12:30pm SGT

Whilst The Broadcast Knowledge avoids product walkthroughs in favour of more educational videos and webinars, AWS is so large that, in some ways, just understanding it is helpful even if you don’t use it and the building blocks with which you build your systems is more or less replicated in other vendors’ platforms so it does pay to keep up. So here we have a webinar on the workflows you can build with AWS – and it’s on twice so you can’t use timezones as an excuse not to attend!

This webcast discusses how new video workflow solutions from AWS directly address the changes businesses are going through. Highlights include:
