down the ground—breaking technology pioneered behind the scenes. it's been an amazing event, and now i'm looking at the tech living on beyond the games. the sustainable innovations fit for the future... ..more precise tracking than ever before... the first i've done for television. ..game—changing new broadcast experiences... that's the magic of volumetric broadcasting. ..and a lasting legacy celebrating accessibility for all. join me for tecthlore paris — beyond the games. in 2024, all eyes were on paris. cheering. the fans, the organisers and, above all, the athletes combined to pull off an amazing show —

helped along the way by transformative technologies. paris 2024 was the largest spectacle ever to take place on french soil. in technology terms, its size means it's a unique test—bed. innovations developed in broadcasting, staging and sport all live on well beyond the games. one of the most exciting new venues of the paris olympics speaks to themes the whole world is grappling with — technology and sustainability. this wave—shaped building is a brand—new aquatic centre. inspired by nature, it's sustainably designed to last beyond paris 202a. made from a timber frame, all of its building materials are bio—based and its 5,000 square metre roof is covered in solar panels, making it completely self—sufficient.

wow. it's an incredible space. one of the ingenious elements of the design is that it's modular, and it can go from its current 5,000 capacity down by half to around 2,500. but innovation does notjust exist in the real world. in the virtual world, a perfect replica of the aquatic centre was crafted, every aspect of it mapped in a real time computer model. a complete digital twin. a digital twin is a representation of a venue in 3d, like a video game. so that helps them to plan in advance, to anticipate, to see how they can plan their operations in the most efficient way.

for broadcasters of the future, digital twins bring an opportunity to try out different camera positions remotely. and for athletes like gold medal—winning british sport climber toby roberts, the tech has been a game—changer. when i first opened the software, i was more just... i was sort of blown away. i wasjust so, like... suddenly i'm in the venue, i'm in le bourget in the olympics. it's really helped me create a mental picture of what it's going to be like competing. just as technology rose to the challenge, helping paris stage a spectacular show, each olympics delivers a step change in the measurement and refereeing of sport. paris 2024 was truly the games when ai arrived, and to see how it will affect sport both now and in the future, i headed to switzerland, to the official olympic timekeeping lab.

oh, i assume that's the right time. omega has been the official olympic timekeeper since 1932, pioneering new technologies throughout the decades. all right. i've got my blades on. i'm on the start line. i'm ready to go. on your marks, set... bang 3.51. i'm not sure usain bolt�*s got much to worry about. new for paris, this smart camera rig is capable of capturing 40,000 pictures per second over the finish line. so, this is my photo finish. it is, and it's looking actually very professional. you know, in athletics, the frontest part of the torso counts. so, you're leaning forwards here... i dipped for the line, i dipped for the line. and actually, another interesting thing is that you stepped on the line while you were crossing it, which is making one of your blades extremely long

on the picture. so, it's multiple pictures that you see here aligned through time. i never thought i'd see myself on a photo finish, and judging by that look on my face, i'm not sure i ever want to again. for the future of sport, this imagery gives judges the position info needed to make even the closest of calls. here you go, paul. thank you. my pb immortalised forever. another visual capture method debuted at paris uses multiple cameras to track athletes from all sides... great, and i can see myself up on the screen up there doing my little dance. ..and, for the first time, ai computer vision was used for body tracking across beach volleyball, gymnastics, tennis, swimming and diving. and diving in particular is extremely interesting because the jump in fact lasts only 1.5 seconds. almost impossible to see differences in athletes' performances with your naked eye. romania's nadia comaneci is a five—time olympic gold medallist and the first gymnast ever to receive a perfect 10 in 1976. she supports this approach

to ai assistance. helping the judging angles, landings, positions — the basic things will be more faster, actually. there are a lot of aspects of ai that will help the athletes. it also makes the fans understand why the judges are doing this, why the deduction was like that. they will explain immediately every question you have. over the course of the games, i've been lucky enough to gain exclusive access to olympic and paralympic athletes using technology to boost their performance. these incredible innovations though, will, of course, have a much broader impact. as usa football captain, lindsey horan piloted her team all the way to gold, beating brazil in the final. she showed us the secret of her success — incredible

muscle mapping tech she's been using to take her performance to a whole new level. you can always improve little things. maybe this will be that much better, or i can be a little bit faster on the field, strengthening one muscle that i didn't know i needed to strengthen. just shows you a better idea of how your muscles are working. that i worked really hard on and now on my left hamstring isn't as great! i tried the tech myself, which all starts with a regular mri scan. well, it's certainly a novel experience. something... a first i've done for television. a couple of days later, i went to london's queen elizabeth olympic park to see my scans transformed. we get the 2d, grainy, black—and—white images that you see from an mri that none of us know what to do with. we have an ai that

actually automatically segments the muscles and the musculoskeletal system, and then we create a true to life form of the human body of who we capture. the body can be compared against itself for symmetry, or against the wider population. now, i noticed when i looked through the results the words "fat infiltration" quite a lot. that sounds pretty bad. what does that mean?! you actually are on the lower end of the spectrum of having an amount of fat inside of each individual muscle. such precision health particularly benefits women, who've been historically overlooked in sports science. there is so much given into the men's side of the game in terms of, you know, injuries, in terms of statistics. now it's starting to progress a lot in the women's game, and they're also seeing women and men differently. around the world, different teams are advancing different technologies. south korea's archers won every gold up for grabs.

behind them, a team of hyundai motor group engineers building advanced robotics and ai training. translation: the equipment fires each arrow with the same angle and the same intensity. only arrows hitting virtually the same spot are selected for competition, ensuring maximum consistency. translation: as you can see, the second arrow struck - slightly to the left and below. and for improved feedback in training, a camera tracks the athlete's posture when shooting — again to ensure consistency, this time in body position. translation: the purpose| of this equipment is to allow athletes to save their poses more simply, offering immediate review. i can't wait to see what archery innovation the engineers will bring to the next olympics.

the olympic games are always a driverfor innovation in broadcast technology, and paris was one of the biggest ever examples of this. i visited the heart of production, the international broadcast centre, which sent coverage to more than 200 countries and regions around the world. during the paris olympics, it was the most content dense place on earth. traditionally, olympic broadcasting has been done via satellite. footage is sent up, back down, and then all around the world. now, this can all happen on the cloud. instead of shipping equipment, tens — or hundreds, sometimes — of racks of broadcast systems and appliances all over the world, you can just have more or less equivalent type of infrastructure spinning up using cloud facilities, do the operation that we need and then spinning them down after the end of the games, with no real physical impact. epic on—site servers sent games content to huge data centres around the world. but this is really

where the heart beats. getting all this content from the venues, you know, managing this, processing this and sending it to the world. 11,000 hours of paris content came through here — enough for a whole year of constant coverage. absolutely phenomenal, and you need a good electrician on your staff with all of this cabling. the cloud team at olympic tech partner alibaba has been working on projects that transform the way broadcasters, visitors and viewers experience the action. the cloud and the altogether, all of this technology can support so many things like that automatically. the clever photo finish cameras, the smart energy for venues and bao, a virtual helper for fans, all ran on the cloud. is it the bao like the... like the bao buns? yeah, yeah! who won the men's

100m at london 2012? ..2012 london olympics was won by usain bolt ofjamaica. - its large language model understands even complex questions. if i was to race usain bolt, but he could only hop, would i win? athletic ability and distance will still play a role in - determining the outcome of it. well, i don't have any athletic ability, so i think he'd still beat me. the cloud combined with al is going to be key to the future of broadcasting. here, olympic partner intel is using its al to generate tv highlights live — an incredible thing to see. i can see things are popping up in real time, so this is actually generating highlights right now. that's right. it takes an input of the live sports competition and the algorithm detects actions in the place.

the algorithm watches the action live and tags it for important events for that sport. video from venue cameras, audio from the event and data like scores, stats and timings all go into deciding what is important. broadcasters, and ultimately viewers, can receive highly tailored highlights packages based on these tags, as the ai spits out custom videos. the sports that don't get a lot of love get coverage now, because we don't have to dedicate a person to sit there and tag this all the time. the way video content is captured and shared is also being transformed thanks to 5g. in paris, intel placed 5g antennae all along the famous river seine, enabling unprecedented broadcast of events on the water. when you think about cameras and wires, you needed a wired camera if you wanted live broadcast. yeah. now we've got points, bridges, that we can put antennas, we're enabling connectivity for the entirety of the river, which makes the broadcasters

able to capture content, upload it and get it to a live audience at home. it's a method that's forever changed the future of water sports coverage, with antennae on boats massively enhancing the experience for tv viewers. what we now can see... you are seeing what the skipper's doing in a way that you've never been able to see before. real live shots from the boat at the sea, during the sailing. amazing. it will be fascinating to watch all these broadcast innovations as they advance in the years to come. with millions watching, there's no doubt the paris games inspired the world. and though the olympics has traditionally got more attention, the paralympics drives forward life—changing innovations for disabled people in and outside of sport. with such a diverse group of athletes and attendees with a wide range of needs, its the ideal opportunity to test drive the latest tech, notjust for future games, but for the wider world in general. some 350,000 disabled fans visited paris —

a city changed for the better, with improved venue access and transport systems. innovative electric vehicles were brought to the fore by olympic partner toyota, including electric aids for wheelchair using athletes and staff. how to move it — brake, one hand... yeah. ..acceleration, one hand. ooh! if you just move down, you go. great. and i'm just setting that to top speed, just so you know. they laugh and i'm off — at a safe limit of 6kmph. this is amazing! wind in my hair! what hair i've got. the easiest a00m i've ever done. crucially, this doesn't require thumb or twisting motions to control. georgios kapellakis, the president of the greek paralympic committee, used one to carry the olympic torch, and paralympic athletes used these at the opening

and closing ceremonies. really easy to drive. i can even do it with one hand — or one arm, in my case. inside the stadiums, new technologies are transforming the way blind fans enjoy the action, with immersive tools rolled out for the most inclusive sports experiences yet. so, this device helps people inside feel the action. can you tell me a little bit about how it works? yeah. so, it's for blind and visually impaired people, so, they can touch these tablets, and we have here a magnet, and the magnet moves to show the position of the ball. so, theyjust have to touch it and they will feel the action of the game. oh, cool. it's moving! the tablet also vibrates at key moments... ooh, ooh! is that a try? ..like a try scored in the rugby. it is. there we go.

it was a try! the tablet can be adapted for all kinds of sports, and i'm hoping it will become a staple forfuture sports events worldwide. the real beauty of this is that there's no audio delay, and so blind people can feel what's happening and really be immersed in the atmosphere. for blind paralympians like team usa long jumper lex gillette, the technology developed at the games brings promise of a more accessible future. gillette has won five silver medals over his career, an inspiring feat. he showed me how a new app helped him navigate the team training camp. automation: go straight. ah, there we go. right, so we're off and moving. turn right and continue seven metres. - turn left and continue four metres. - turn right... yeah, all right. got us around the corner. to map each space, a 360 degree point cloud is painstakingly collected by hand.

ai and computer vision then takes this 3d data and crafts the step by step guide. continue eight metres. slight left and - continue four metres. slight left... go straight. arrived, running track. there you go. so that was pretty good — that got us to the track pretty unscathed, i would say. yeah. how was that to use, for you? yeah — definitely... it was really interesting trying to figure out what it means to rotate left, or turn left. so, i think, after a while, you use the solution a few times, you get used to it and you learn that path pretty easily. i canjump six metres, so i kind of know how far that is. yeah. though this is the only paris site map so far, the team's ambitions are huge for the future. this year's deployment has been focused on the athletes, primarily, and specifically at the performance centres and the training grounds.

and in coming games, we're hoping to expand that to visitors and staff and people attending the games, as well. perhaps most inspiring are the paralympians using technology to push the boundaries of the human body and even make it onto the podium. i met team usa's brian siemann, a three—time paralympian who medalled in both the 400 and 800 metre sprints in paris. ahead of the success, the us track and field star had been wearing a unique high—tech sleeve from a start—up called nextiles. you just slide it up, make sure that it is lined up with your elbow. it is the only sleeve in the world that has the technology that wheelchair racers can currently use to actually collect real time cadence data. this first—of—a—kind data comes from biometric threads concealed in the elbow, combined with data from an accelerometer. it's measuring how quickly

and how far those fabrics are actually going back and forth, and then giving you real time data so that you can actually adjust your training session. brian uses an aluminium racing chair with carbon fibre features, and his phone attached. you can sort of make adaptions in real time from what you're seeing. yes. that's really cool. well, i'm going to let you crack on. all right. wow. brian's personal best is 400m in 47.84 seconds. holy moley, he's halfway round already. wow, amazing! how easy is it to find technology like this that's tailored specifically towards disability sport? it's so hard to get companies to invest in athletes with disabilities and make sure that their tech works for us. to have something like this to help improve my performance

is really special, but i think, in the big picture as well, it's advancing accessibility for everyone. i know the challenges of navigating life with a disability, so seeing technology developed for athletes and everyday people alike is powerful. even more important is that this lives on as part of a long—lasting legacy. push the sport and the para sport directly to the younger and the person with disability, and in more than that, for me, the behaviour is very important. if we can show, if every public can look the paralympic record, i'm sure that they change their view around the disability. when i began exploring olympic tech for paris, i had no idea of the range and breadth of innovation i would find, and the passionate people behind it all driving it forward. i cannot wait to see

the impact it has, not just in future games, but much further beyond. good afternoon. severe weather for some of us as we prepare to welcome in the new year, including an amber weather warning valid until five o'clock this afternoon to heavy rain across parts of the highlands. weather warning issued by the met office, valid until 5:00 this afternoon for heavy rain across parts of the grampians and the highlands, there could potentially be some more flooding. the situation has been improving here, but there will still be some more showers within the area, the heaviest

of the rain having tracked further southwards. and wherever you are across the uk tonight it is going to be very blustery. so let's take a look at the picture as the clock chimes midnight. some wintriness across the higher ground, especially of northern scotland. watch out for some icy stretches here and it's very windy across the central belt, southern scotland, northern england. this is where we're expecting the heaviest of the rain to be across north wales into the north midlands. further south it's largely dry, plenty of cloud but very blustery. gusts of wind across the southern half of the uk of up to 45 to 50 miles an hour potentially, and then into new year's day itself, and that rain continues to track its way further southwards. wet and windy across the far south, some sunshine emerging further north. it does stay rather windy. we start to draw down a northerly wind and there will be some wintriness over the pennines and over the cumbrian fells. two against more wintry showers feeding into scotland. temperatures for many, especially towards the south, dropping off as the day wears on. so the rain clears towards the south. as we head through wednesday night and into thursday, we draw down a northerly wind, and that's going to allow this arctic air to spill its way further southwards. so, a very cold—feeling

day on thursday and we'll start off with a widespread frost. many of our temperatures below freezing. watch out for some icy stretches too, especially where we've seen recent rain. and on thursday, while many of us will stay dry, there will be some sunshine around, it will be feeling very cold throughout and there'll be the risk of some wintry showers running down these north sea facing coast into northern parts of northern ireland and of course, across northern scotland too. temperatures not getting much past 2 to 5 c north to south, but in exposure to that brisk northerly wind, it's going to feel even colder than that, as if it's below freezing. we see a slight shift in wind direction as we head into friday. more of a north westerly, so the chance of some wintry showers for northern ireland and down through the cheshire gap into north wales, perhaps, and also across north western scotland. but for many of us, again, it's dry, with some sunshine and certainly still feeling very cold. bye bye.

live from london. this is bbc news. we're live in tokyo as japan toasts the new year. we'll bring you all the major celebrations as the clock strikes midnight around the world. but some of those celebrations have been cancelled here in the uk, with yellow storm warnings in place in large parts of the country. ukraine says it has fired a missile from a sea drone to

take down a russian helicopter. officers say the attack is the first of its kind. and medics in gaza say six newborn babies have died from hypothermia in a fortnight. we'll bring you a special report. hello, i'm christian fraser. we are going to take you straight to tokyo, japan where the clock has just gone midnight, welcoming in the new year of 2025.

ringing in the bell...
