With smart speakers, mobile phones and computers all sporting voice-controlled interfaces, it’s no surprise that smart TVs, Apple TVs and others can be voice controlled. This webinar looks at how much consumers expect control and what they expect.
Getting voice right, can be a really big differentiator in terms of enjoyment and confidence of a service and the speakers discuss how that can enhance retention and growth.
As seen with a recent update to Apple’s HomePod which allows it to recognise who’s speaking, voice can be used for personalisation, security and privacy when carefully applied to the service.
The webinar will also discuss fraud reduction and ecommerce opportunities.
MPEG DASH is a standardised method for encapsulating media for streaming similar to Apple’s HLS. Based on TCP, MPEG DASH is a widely compatible way of streaming video and other media over the internet.
MPEG DASH is now on its 3rd edition, its first standard being in 2011. So this talk starts by explaining what’s new as of July 2019 in this edition. Furthermore, there are amendments already worked on which are soon to add more features.
Iraj Sodagar explains Service Descriptors which will be coming that allow the server to encapsulate metadata for the player which describes how the publisher intended to show the media. Maximum and minimum latency and quality is specified. for instance. The talk explains how these are used and why they are useful.
Another powerful metadata feature is the Initialization Set, Group and Presentation which gives the decoder a ‘heads up’ on what the next media will need in terms of playback. This allows the player to politely decline to play the media if it can’t display it. For instance, if a decoder doesn’t supply AV1, this can be identified before needing to attempt a decode or download a chunk.
Iraj then explains what will be in the 4th edition including the above, signalling leap seconds and much more. This should be published over the next few months.
Amendement 1 is working towards a more accurate timing model of events and defining a specific DASH profile for CMAF (the low-latency streaming technology based on DASH) which Iraj explains in detail.
Finishing off with session based DASH operations, a look over the DASH workplan/roadmap, ad insertion, event and timed metadata processing, this is a great, detailed look at the DASH of today and of 2020.
Many people have little free time so there is hot competition amongst entertainment services for those precious minutes.
Red Bee Media’s Steve Russell explains how they have moved to a service based model for their platform which allows a single platform to be used by many customers. This allows them to focus on a single platform, making sure this can quickly iterate and provide new services the moment their customers think of them.
Simon Eldridge from SDVI tells us about he’s bringing manufacturing methodologies to the media industry allowing companies to work much more efficiently and Bill Gash talks about about how pay TV, mobile and Telco operators are consolidating to have the power to push back against the internet giants by combining customer attention, spending power and quality of customer experience.
The panel conversation starts discussing the ‘dark’ episode of The Game of Thrones which led to many complaints when viewers watched the episode in environments and on displays which didn’t show enough contrast – unlike the monitors in the grading suite – leading to people being unable to see what’s happening in parts of the episode. Quality of experience, says Bill Gash, is very difficult and the broadness of what constitutes quality of experience can be big challenge for producers who are new to directly delivering to the viewer.
Adapt and evolve is the ‘product management’ approach to launching services, explains Steve Russell, which bucks the trend of launching services which used to take a lot of Capex and a long project to set up. The more recent priorities are speed to market and constant iterations to improve the service.
iflix is a great example of an innovative service which has managed to achieve scale, from 50,000 to, now, 25 million subscribers in less than 3 years. Bill Gash gives this and other examples such as Formula 1, which show the possibilities of growing into and entering this larger market. This shows it’s not just about large players hitting back against the internet giants, but also a recognition that innovating can allow you to take those subs and those ‘minutes of attention’ away from other services.
The panel, from the Content Everywhere Hub, finishes by discussing the importance of adapting to the countries you’re operating it and by identifying the key advice for anyone developing their service in this market.
Twitch is an ambassador for new codecs and puts its money where its mouth is; it is one of the few live streaming platforms which streams with VP9 – and not only at, with cloud FPGA acceleration thanks to Xylinx’s acquisition of NGCODEC.
As such, they have a strong position on AV1. With such a tech savvy crowd, they stream most of their videos at the highest bitrate (circa 6mbps). With millions of concurrent videos, they are highly motivated to reduce bandwidth where they can and finding new codecs is one way to do that.
Principal Research Engineer, Yueshi discusses Twitch’s stance on AV1 and the work they are doing to contribute in order to get the best product at the end of the process which will not only help them, but the worldwide community. He starts by giving an overview of Twitch which, while many of us are familiar with the site, the scale and needs of the site may be new information and drive the understanding of the rest of the talk.
Reduction in bitrate is a strong motivator, but also the fact that supporting many codecs is a burden. AV1 promises a possibility of reducing the number of supported codecs/formats. Their active contribution in AV1 is also determined by the ‘hand wave’ latency; a simple method of determining the approximate latency of a link which is naturally very important to a live streaming platform. This led to Twitch submitting a proposal for SWITCH_FRAME which is a technique, accepted in AV1, which allows more frequent changes by the player between the different quality/bitrate streams available. This results in a better experience for the user and also reduced bitrate/buffers.
YueShi then looks at the projected AV1 deployment roadmap and discusses when GPU/hardware support will be available. The legal aspect of AV1 – which promises to be a free-to-use codec is also discussed with the news that a patent pool has formed around AV1.
