The Fox Report Barry Fox’s technology column Real vs virtual events – the good, the bad and the tough I f more proof were needed that Zoom-style online conferencing is no substitute for a live event, the DTG (Digital Television Group) Summit 2022 – Television Beyond Imagination – hosted on a real stage at Kings Place in London, offered it in spades. Not just any old live event, of course. The speakers have to know their subject and not indulge in blatant product plugging, or run over time and spoil things for others who follow. Otherwise, the audience just buries their heads in mobiles, catches up on email or leaves the hall for a well-earned cup of tea. Metaverse? Despite a few niggles, the DTG was an object lesson in how to do it right. I had gone along with one main object in mind. To find out what people really mean when they talk about the Metaverse; and whether people who talk about the Metaverse really know what they mean by it. David Sidebottom, principal analyst at Futuresource, says the figures show that 64% of everyone are ‘aware of the Metaverse, but most do not know what it is’. I would have liked to have passed on some of the other statistics which Futuresource offered, but the data was displayed as projected slides, with tiny text and graphics, camouflaged by light colour fonts on a white background that were largely illegible from halfway down the hall. Likewise, although Prof Lucy Kueng, strategic advisor, senior fellow Reuters Institute, University of Oxford had useful things to say about the way the TV and streaming market is fragmenting, so that viewers find it increasingly hard to find what they want to watch, and then tame the tech needed to watch it, she too disguised her offering by using slides which were similarly illegible. You’d think that tech and PR/comms gurus at a conference devoted to techbased media could master Powerpoint in an audience-friendly way, but it seems there are still lessons to be learnt. Despite this, it was a useful and informative event. 10 Yet more streaming Today’s streaming giants like Netflix, Prime, Britbox and Mubi are battling for a finite pool of paying subscribers. There are more on the way – a service from Paramount will be bundled with Sky Cinema and via other routes as well. Speaking as someone with a cupboard full of streaming boxes and dongles (Roku, Now, Shield, Fire, YouView…) which are all able to get some streaming services but not others, I asked Dan Fahy senior VP in charge of streaming at Paramount UK, what I would needed to watch the new service on a big screen. Fahy appeared surprisingly well informed for a sales boss and assured that all devices, including Amazon Fire sticks, but with the exception of Freesat receivers, would be able to pull in Paramount. The Freesat exclusion makes sense because Paramount is in bed with Sky, and the last thing Sky wants is to encourage punters to watch programmes for free with a Sky dish and Freesat box, instead of a Sky dish and Sky box. Rufus Radcliffe, managing director ITV On Demand, fleshed out plans for a new ITV streaming service – curiously called ITVX – he needed to explain that it is not X-rated content! Matthew Brooks, lead R&D engineer, BBC R&D talked intriguingly about the BBC’s work on ‘object-based media’ which makes raw content easier to edit automatically, for instance to fit a TV programme to an available time slot. Everything relies on metadata, embedded in the content alongside picture and sound. You can play with some software tools here: www.bbc.co.uk/makerbox Paul Nesbitt from kids’ creator interactive community platform Twitch, Rhys Hancock of Metavision, Jo Redfern of 24 Watts, Robin Cramp from Production Park for XPLOR, John Cassy of Factory 42, and Zillah Watson, former Head of BBC VR and now a ‘media & metaverse consultant’, all had views on where the Metaverse is going, and what Gen Z undersixteens born into the age of streaming are doing with it. Some of the speakers fell into the trap of lumping together all young people of a similar age, when anyone who talks to teens knows they have hugely disparate behaviour patterns – some semi-permanently sequestered in warm dark rooms with screens and others out on a cold soccer pitch. The consensus is probably best distilled down to the Metaverse is a mash-up of gaming, entertainment and education experienced with a variable mix of conventional TV screen viewing, virtual reality and augmented reality. While outdoor kids want to kick real footballs with trendy trainers, indoor kids want to create an alternative existence in a virtual environment with a personalised avatar wearing expensive virtual trainers. No one talked about practical issues, like how people will handle real life in the real world without a VR headset. Several speakers agreed that young people want a ‘low-friction’ seamless experience with no need to download apps or submit to multiple sign ins. But so do older people – although they have learned the hard way that the Internet is thick with thieves, scammers and conmen waiting to pounce on any security short cut. Virtual McAfee A few days after the DTG event, McAfee, the computer security company that was taken over by Intel ten years ago in a tortuous string of deals, and which then went solo again earlier this year with more tortuous dealing, had little choice but to hold its 10th Annual ‘Labs Day’ as a virtual event, since its speakers from Holland, Dallas Texas, France, Germany and the UK were talking to journalists spread right across Europe. I hope next year’s event will be live again because the virtual gathering went on for far too long for virtuality (five painful hours with only a 15-minute break) and offered too little technical content. Real speakers in a real room would surely have sensed a loss of audience interest. Nevertheless, it was good to be reminded that hackers are now hijacking PCs and using them to mine cryptocurPractical Electronics | July | 2022 rency. The tell-tale signs are busy hard drives and racing fans when the PC should be idle; but the way Windows carries out housekeeping, such as indexing during idle hours can disguise a hijack. It’s to be hoped that good protection against malware will block the intrusion, but I was left wanting to hear much more about how to do this. I asked what McAfee thought about Microsoft/Windows Defender, the malware protection that comes free with Windows. It is, after all, in Microsoft’s interests to stop its OS being over-run. But Microsoft is limited by trade laws in how hard it can promote Panasonic’s latest Toughbook vitual promotion free Defender against paid-for alternaevent was a textbook example of how not to tives like McAfee or Norton. organise invitations.
