Webinar: Talking to the TV: Transforming the viewing experience with voice control

Posted on 13th May 2019 by Russell Trafford-Jones

Thursday 16th May 2019, 16:00 BST / 11am EDT / 8am PDT

Controlling services by voice is on the rise. Recently we have seen Google move all their Nest hardware control into Google Assistant and the abilities of Alexa and Siri continue to grow. All of these smart speakers and voice-controlled AI assistants have seen rapid adoption in homes, the UK being the biggest adopter with voice assistant devices now used in more than a quarter of all households.

With a shift away from the on-screen EPG and clunky remote controls to a world where any content is a voice command away, who owns the voice interface with the consumer and the vast amount of valuable data it creates? Does this put more power in the hands of the Silicon Valley tech giants as their voice assistants and AI algorithms become a new gatekeeper? And how should content owners respond?

This webinar explores the value of voice control for content, and finds the best strategies for broadcasters and platform operators to develop voice interfaces and maintain control of the user experience.

Video: Per-title Encoding at Scale

Posted on 11th April 2019 by Russell Trafford-Jones

MUX is a very pro-active company pushing forward streaming technology. At NAB 2019 they have announced Audience Adaptive Encoding which is offers encodes tailored to both your content but also the typical bitrate of your viewing demographic. Underpinning this technology is machine learning and their Per-title encoding technology which was released last year.

This talk with Nick Chadwick looks at what per-title encoding is, how you can work out which resolutions and bitrates to encode at and how to deliver this as a useful product.

Nick takes some time to explain MUX’s ‘convex hulls’ which give a shape to the content’s performance at different bitrates and helps visualise the optimum encoding parameters the content. Moreover we see that using this technique, we see some surprising circumstances when it makes sense to start at high resolutions, even for low bitrates.

Looking then at how to actually work out on a title-by-title basis, Nick explains the pros and cons of the different approaches going on to explain how MUX used machine learning to generate the model they created to make this work.

Finishing off with an extensive Q&A, this talk is a great overview on how to pick great encoding parameters, manually or otherwise.

Video: Using CMAF to Cut Costs, Simplify Workflows & Reduce Latency

Posted on 5th March 2019 by Russell Trafford-Jones

There are two ways to stream video online, either pushing from the server to the device like WebRTC, MPEG transport streams and similar technologies, or allowing the receiving device to request chunks of the stream which is how the majority of internet streaming is done – using HLS and similar formats.

Chunk-based streaming is generally seen as more scalable of these two methods but suffers extra latency due to buffering several chunks each of which can represent between 1 and, typically, 10 seconds of video.

CMAF is one technology here to change that by allowing players to buffer less video. How does this achieve this? An, perhaps more important, can it really cut costs? Iraj Sodagar from NexTreams is here to explain how in this talk from Streaming Media West, 2018.

Iraj covers:

A brief history of CMAF (Common Media Format)
The core technologies (ISO BMFF, Codecs, captions etc.)
Media Data Object (Chunks, Fragments, Segments)
Different ways of video delivery
Switching Sets (for ABR)
Content Protection
CTA WAVE project
Wave content specifications
Live Linear Content with Wave & CMAF
Low-latency CMAF usage
HTTP 1.1 Chunked Transfer Encoding
MPEG DASH

Webinar: State of the Broadcast Industry 2019

Posted on 6th February 2019 by Russell Trafford-Jones

Ooyala heroically compile a report and webinar discussing the state of the media and broadcast industry each year and Jim O’Neill is here to talk us through it for 2019. The report itself discusses penetration of 4K screens, the demographics of online streaming, 5G, ATSC and much more and this webinar looks at:
