The Fox Report Barry Fox’s technology column Freely’s success will depend on good hardware F reely is the key to switching the UK from traditional, linear TV broadcasting to IP/Internet TV. But what is Freely? The official Freely website (www.freely.co.uk/ how-freely-works) is aimed at those with a short attention span, with next to no nitty-gritty: Less scrrrrrrrrolling, more streaming. No more getting your detective on to track down your next fave across different apps. Save loads of time by finding everything in one place. Use the new MiniGuide to whizz from the latest season of The Traitors, to Love Island, or even The Great British Bake Off. If you needed an excuse to get out of going out, it’s this! I have done my best to get more details and noted the obstacles, if only for easy reference if – I fear when – things go wrong. Although Freely is clever, there looks to be plenty of room for that. The technology bundles Freeview Digital Terrestrial broadcast TV channels with a selection of streamed channels. The company behind the technology is Everyone TV, until 2023 known as Digital UK. This is a joint venture owned and supported by the UK’s leading public service broadcasters: the BBC, ITV, Channel 4 and Channel 5. Some 20 years ago, Digital UK handled the huge tasks of digital switchover and launching Freeview from digital terrestrial masts and Freesat, the same satellites used by Sky for pay viewing. At that time, Digital UK saw the value of providing technical journalists with solid facts on the issues and answers to technical questions. So Digital UK employed an ex-technical journalist who understood what technical journalists needed to know and where to find technically solid answers to questions. The switchover went more smoothly than anyone dared hope, and David Scott, then CEO of Digital UK, was justly knighted in 2013. Everyone/Freely launched in 2024 with a speech by current CEO Jonathan Thompson at the Digital Television Group (DTG) Conference and now describes itself as “the Practical Electronics | May | 2026 organisation leading the evolution of free TV in the UK”. Sadly, there has been little communication between Everyone/Freely and the technical press. Freely employs a publicity agency, which describes itself as specialising in entertainment, arts and culture. Freely’s own press staff appear to have little interest in, or understanding of, the technology that makes Freely tick. Some of the companies selling Freely hardware are equally difficult to talk to. Viewers are used to near-instant switching between live broadcast channels. However, some delay is inevitable when streaming live TV because the incoming IP stream must be buffered and processed. Freely combines both broadcast and IP delivery, so delays may be uncomfortably obvious. The amount of memory and processing power inside Freely hardware is inevitably fixed at the time of manufacture. The software and firmware can be updated, but not the electronics. This is why smart TVs and HDMI bolt-on streaming devices, like Roku and Amazon Fire sticks, become obsolete. The saving grace is that these sticks have generally been relatively cheap. So far, at least, Freely bolt-on devices are expensive. The first to appear, Netgem’s Pleio ‘puck’, costs around £100, largely because it has gaming features not everyone needs. The ‘cheaper’ Aero from Manhattan costs around £70. The Humax AuraEZ 4K Recorder with “Built-in Freely” costs £250 (https://humaxdirect. co.uk/products/humax-auraez-4kfreely-recorder). Humax’s advertising says: Just plug in and Aura EZ is ready to watch in minutes. Record up to four channels at a time while watching a fifth live, when connected to an aerial..Generous 2TB hard drive stores up to 1,000 hours of recordings. The Humax Aura EZ app will make it simple for Aura EZ owners to navigate, plan and schedule recordings remotely from anywhere, so the shows and movies they love most will always be available to watch – even on the go...no aerial or dish required. However, the ‘small print’ warns: “The recording feature on Aura EZ requires an aerial.....Recording is not compatible with the Freely platform.” Humax has a tech-savvy spokeswoman who explains: “The recording function is via the aerial and the Freely part is a separate interface. They do overlap in that you can be in the Freely interface and press the record button, which then brings up a guide overlaid on the top, so it’s integrated in that way. But you cannot record any Freely channels”. Although Freely’s website is frustratingly fluffy, it promises clearly: “All you need is Wi-Fi”. Will customers read the Humax small print carefully? Or will they buy a Humax-with-Freely recorder, try unsuccessfully to record a stream, and return the box for a refund? The telltale will be whether Amazon sells the Aura but adds the standard customer warning about “high return rates”. Manhattan, a company which also has a tech-savvy spokesperson, explains: “There is no aerial input.. (on the Aura)...our view is that when you’re buying a Freely box, you’re specifically choosing streaming-first TV. Including an aerial socket would have...created a less optimal experience, because Freely TVs with both options prioritise the aerial signal – meaning you lose the ability to pause live TV...” So far, the only radio stations on Freely are from the BBC. However, as Manhattan explains, “if you go to ‘all apps’ on the Manhattan Aero, ‘Radioline’ is included and it has a wide range of stations. It’s a global network but knows you’re in the UK and provides accordingly. There are also apps like Capital FM, Classic FM, Heart and others on the Manhattan Aero.” This is all starting to sound rather complicated... The BBC uses a wide variety of data rates for different applications. The main BBC stations (inside the UK with HQ Geoblock, via internet continued on page 25... 13
