voice—over: this is bbc news. we'll have the headlines for you at the top of the hour, which is straight after this programme. tecthlore we go in search of the most exciting innovations around the world. i go behind the scenes on special missions to uncover the technology powering the paris 2024 olympic and paralympic games. i am a huge fans of the olympic games and i am lucky enough to be here in paris and let me tell you, the atmosphere is incredible. i'm looking at our

cutting—edge technology is helping people across the globe share this experience. ——at how. i'm stepping into the high—tech international broadcast centre at the heart of the games. i am unleashing my inner sprinter at the olympic timekeeping laboratory 0lympic timekeeping laboratory while making a splash with the latest smart goggles and testing my skills at an ai talent scouting lab. this is tecthlore paris, the global experience. this is my first trip abroad to see a games. usually i'm watching on television, along with billions of other fans around the world. it is a shared experience, catching every thrilling high and a gut wrenching low, whether you here in person or glued to your screens at home.

i'm starting my deep dive into the tech powering the paris game at an epicentre for global television, the international broadcast centre. this looks like a pretty big set up to meet but its organisers adopt more advanced tech. this is actually shrinking and becoming more streamlined with each games. this hive of activity is the heart of production, with the heart of production, with the paris games broadcaster more than 200 countries and regions around the world. during the olympics, this broadcast centre will become the most content edge to place on earth. traditionally cutting has been done by satellite, footage is sent up, back down and then all around the world but these paris games will be the first were most of the data is sent via the cloud rather than airways. a meeting the man behind this mammoth project to

tv stations around the world. it is absolutely phenomenal and you need a good electrician on your staff. cloud team and olympic tech partner ali barber 0lympic tech partner ali barber is enabling projects that transform the way broadcasters, visitors and viewers experience the actions. visitors and viewers experience the actions-_ visitors and viewers experience the action— the actions. cloud and ai technology _ the actions. cloud and ai technology that - the actions. cloud and ai technology that i - the actions. cloud and ai technology that i did - the actions. cloud and ai technology that i did this technology that i did this technology that i did this technology that supports so many scenes.— technology that supports so many scenes. the clever photo finish cameras, _ many scenes. the clever photo finish cameras, this _ many scenes. the clever photo finish cameras, this might - finish cameras, this might energy for venues and a virtual helper for fans energy for venues and a virtual helperforfans all run energy for venues and a virtual helper for fans all run on cloud. is that like the bounce? yes. who won the men's 100 metres yes. who won the men's100 metres at london 2012? it was one boat was _ metres at london 2012? it was one boat was bolt _ metres at london 2012? it was one boat was bolt of— metres at london 2012? it was one boat was bolt of jamaica. l one boat was bolt of jamaica. it's large language model understands even complex question. if i could race usain bolt but he could only hope, would he win? i do not have any

athletic ability so he would still beat me. the cloud combined with al is going to be key to future in broadcasting. 0lympic partner intel is using its ai 0lympic partner intel is using its al to generate tv highlights, an incredible thing to see. to see things popping up to see. to see things popping up in real—time is that this is actually generating highlight right now. actually generating highlight riaht now. ., v right now. that's right. it takes an _ right now. that's right. it takes an input _ right now. that's right. it takes an input of- right now. that's right. it takes an input of the - right now. that's right. it takes an input of the live | takes an input of the live sports competition, an algorithm detects action in the place. algorithm detects action in the lace. . ., algorithm detects action in the lace. ., ., ., . , place. the algorithm watches the action — place. the algorithm watches the action life _ place. the algorithm watches the action life and _ place. the algorithm watches the action life and takes - place. the algorithm watches the action life and takes it. the action life and takes it for important events for that sport. video from venue cameras, orderfrom the sport. video from venue cameras, order from the event and data like scores, stats and is coming or going to deciding what is important. broadcasters and ultimately viewers can receive highly tailored highlight packages based on these tags, as the ai spits out custom videos.— these tags, as the ai spits out custom videos. the spores that do not get _ custom videos. the spores that do not get a — custom videos. the spores that do not get a lot _ custom videos. the spores that do not get a lot of— custom videos. the spores that do not get a lot of love - custom videos. the spores that do not get a lot of love get - do not get a lot of love get covered now because we do not have to dedicate a person to

take this and now the editor can spend more time focus on the storytelling, the creative but and not worry about staying up but and not worry about staying up all night taking video. another innovation gaining momentum is volumetric broadcasting, and 3d camera rig is installed into the athletes village. using 21 cameras and sensors, it creates subjects from every angle to create a 360 degrees image. now, it may look like i'm stood the arc de triomphe but i am actually at the international broadcast centre, that is the magic of volumetric broadcasting. you can because _ volumetric broadcasting. you can because a _ volumetric broadcasting. you can because a video - volumetric broadcasting. gm. can because a video of volumetric broadcasting. gm, can because a video of some into your living room, dance on your coffee table but what we really like about it is that the broadcasters, they can insert the athlete into the virtual environment and interview them just like we're standing next to each other but i could be in london or paris and them in any other place in the world. and them in any other place in the world-—

the world. for athletes, of course. — the world. for athletes, of course, nothing _ the world. for athletes, of course, nothing is - the world. for athletes, of course, nothing is more i course, nothing is more important to capture than their timing. so i am headed to switzerland to see how official 0lympic timekeepers and making every millisecond count. deepin deep in the swiss mountains, lies the tiny village of corgemont, where i have been granted exclusive access to the official timekeeping lab from 0lympic partner, 0mega. i assume that's the right time. 0mega has been the official games timekeeper since 1932, pioneering new technologies throughout the decades. back then, one watchmaker was sent with 30 chronographs all the way from switzerland to los angeles. at the olympic games in paris, we are deploying sophisticated computers, computervision, computers, computer vision, artificial intelligence, sophisticated software to capture every moment of athletes�* performances between start and finish. 0h, between start and finish. oh, wow, this is cool. well, we are having an original setup, same as the olympics.

i am kicking off at the lab test track. speakers on starting blocks sound the opening shots of games races so everyone hears the electric pistol at the same time. i have got my blades on. i have got my blades on. i am on the start line and ready to go. on your marks, set... 3.51. i�*m not sure who usain bolt has got much to worry about. new for paris is as smart camera rig capable of capturing 40,000 pictures per second over the finish line. so this is my photo finish. it is and it is looking actually very professional. laughter. you know, in athletics, the frontest part of the torso counts so you�*re leaning forward here... i- here... idip to here... i dip to the line. and actually, and other interesting thing is you stepped

onto the line while you were crossing it which is making one of your blades extremely long on the picture. so it is multiple pictures that you see here aligned through time. i never thought i would see myself on a photo finish and judging by the look on my face, i am not sure on my face, iam not sure i on my face, i am not sure i ever want to again. at the games, this imagery givesjudges the at the games, this imagery gives judges the position information needed to make even the closest of calls. here you go, paul. thank you. my thank you. my pb immortalised forever. another innovation requires multiple cameras that track athletes from all sides. i can see myself up in the screen, do a little dance. for the first time, this ai computer vision is being useful body tracking across beach volleyball, gymnastics, tennis, swimming and diving. gymnastics, tennis, swimming and diving-— and diving. diving in particular— and diving. diving in particular is - and diving. diving in i particular is extremely interesting because the jump particular is extremely interesting because thejump in fact lasts only 1.5 seconds, almost impossible to see differences in athletes performances with your naked eye.

inside already. it has been a fantastic backdrop to the olympic diving, water polo and 0lympic diving, water polo and artistic swimming events. my visit before the game started took me right back to my golden years as a swimmer and british record holder. but you can really tell here is how it has been designed around atmosphere and at that level of support from people watching is so important to a swimmer, the smell of the chlorine, the sense of anticipation in the air, it is almost making me think about a comeback. from one aquatics centre to another, i�*m getting a chance to making a splash at the london venue. these are not your average swimming goggles. i have my wetsuit, goggles, iam ready to jump wetsuit, goggles, iam ready to jump in. they collect data as you swim and use augmented reality to show that on the

lands. i can see a timer, it tells me how long i have been swimming, i can set my strokes per minute rate at the bottom and i can also see my heart rate which is not that light because i am unfit. these are been developed alongside scott dickens who competed right here at the london games back in 2012. how�*s it going. how does it feel to be back here? it is it feelto be back here? it is emotional. _ it feelto be back here? it is emotional. looking - it feelto be back here? it is emotional. looking at - it feel to be back here? it 3 emotional. looking at the pool, the lake. i swam my very last competitive racier. i�*m getting goosebumps just competitive racier. i�*m getting goosebumpsjust thinking competitive racier. i�*m getting goosebumps just thinking about it. goosebumps 'ust thinking about it. ., , ., , . goosebumps 'ust thinking about it. ., , . it. how did your experience as an olympian _ it. how did your experience as an olympian ledger _ it. how did your experience as an olympian ledger to - it. how did your experience as | an olympian ledger to develop an 0lympian ledger to develop this product? an olympian ledger to develop this product?— this product? when you are in the ool this product? when you are in the pool or— this product? when you are in the pool or water _ this product? when you are in. the pool or water environment, there is nothing guiding you, how fast you�*re going, what

hello there. heat and humidity is set to build as we go through the weekend, but we do need to caveat that with saturday, there is going to be quite a lot of cloud around for most of us. but it will turn increasingly very warm and very humid from sunday onwards. let�*s take a look at what�*s happening, then. this weather front will bring more cloud on saturday into south west england and wales, and with isobars quite tightly packed together further north, that�*s going to feed in plenty of showers, particularly from west to east across scotland throughout the day. southern scotland, northern ireland keeping some sunshine. england and wales, quite a lot of cloud feeding in. at times, there�*ll be some light, drizzly rain and poor visibility through the irish sea coast there. top temperatures, though, 24 degrees. that�*s still 75 fahrenheit. but as we move out of saturday and into sunday,

this area of low pressure is going to move in, and allow the winds to change to a southerly direction. and that means we�*re going to tap into some very hot weather that�*s taking place across the mediterranean at the moment. so early morning cloud will break up quite quickly. a lot of dry, settled, sunny weather right across the country on sunday. increasingly hot, increasingly humid. this weather front threatening to the northwest, but it will stay away during the daylight hours. 16—23 degrees likely in scotland. highest values, though, of 28 — 82 fahrenheit — in the southeast. that will lead to a very humid night to come, and on monday, the heat is likely to peak. we could see some record—breaking heat in bordeaux, if we get temperatures in excess of 41 degrees. but for the southeast, we�*re likely to see temperatures peaking somewhere around 32—33 degrees. at the same time, further north, that weather front moves in, and with that heat and humidity coupled with that front, we are likely to see some sharp, thundery downpours.

really quite torrential, heavy rain for a time. that will freshen the story up further north, but we�*ve still got that heat and humidity clinging on in the southeast of england. 0ne low eases away, another is likely to move in, again bringing some unsettled weather. not for all of us, but certainly a fresher feel as we go through the week ahead. there will continue to be some lengthy spells of sunshine, particularly across southern england. showers or longer spells of rain likely further north.
