:00:00. > :00:09.This week, eye-popping colours, formation madness,
:00:10. > :00:44.Ask because I'm just wondering how good your pixels are.
:00:45. > :00:53.I'm not asking how many you got, just how good they are.
:00:54. > :00:56.See, there are many ways to improve your TV picture.
:00:57. > :00:58.One is to improve the resolution, how many pixels you have.
:00:59. > :01:02.That is why standard def is not as good as high-def,
:01:03. > :01:05.which in turn doesn't look as good as ultrahigh def.
:01:06. > :01:07.But, another way to improve the picture
:01:08. > :01:13.is to increase the colour depth, the level of detail in the colours.
:01:14. > :01:16.Over the past year, one or two top-end TVs have started
:01:17. > :01:19.to offer a new format which some are daring to call a game-changing
:01:20. > :01:28.They are calling it "High Dynamic Range," HDR,
:01:29. > :01:32.and this year it is set to be a thing on many new industry TVs.
:01:33. > :01:36.But is it just industry puff, or is it really time to buy a new TV
:01:37. > :01:43.We asked Dan Simmons to find out what HDR is, what it does,
:01:44. > :01:56.What interests me is what it looks like.
:01:57. > :01:59.Now, if that's going to have ten letters and numbers behind it,
:02:00. > :02:04.so be it, but I wouldn't be able to tell you what they are.
:02:05. > :02:07.I don't think many people know about High Dynamic Range itself.
:02:08. > :02:10.Most people when they first see it take a step
:02:11. > :02:16.Because sometimes to them it looks to them as if the person is actually
:02:17. > :02:26.Ted has been selling TVs for 18 years.
:02:27. > :02:30.He says it is a big deal so I have come to the HQ of Sony to
:02:31. > :02:45.And you won't be able to see this because you are watching in HD
:02:46. > :02:55.What more am I going to get from something called HDR?
:02:56. > :02:58.That's what we have set up on this TV, you can see
:02:59. > :03:02.HDR is the new broadcasting standard which gives you much more colour
:03:03. > :03:05.and brightness information compared to regular 4K.
:03:06. > :03:10.These are both 4K pictures but this one has High Dynamic Range.
:03:11. > :03:15.For example, you can see the skin tones are much
:03:16. > :03:26.HDR cameras capture colour information using a longer ten bit
:03:27. > :03:33.So more colour hues are available, making things look more real.
:03:34. > :03:37.For the first time, these TVs can play that back.
:03:38. > :03:42.Our eyes can see a huge spectrum of brightness, about 15 stops' worth.
:03:43. > :03:45.But up until now TVs have had a problem
:03:46. > :03:52.The picture burns out too easily or dark bits lose detail, for example.
:03:53. > :03:57.HDR delivers 85% of what most of us can see, resulting in a picture that
:03:58. > :04:05.holds on to the darker detail, even when bright lights are in shot.
:04:06. > :04:13.And in here, look at all that detail in the trees.
:04:14. > :04:18.And these suns, one is quite big and the other is much smaller.
:04:19. > :04:21.Is that something you get when you shoot in HDR?
:04:22. > :04:24.Yeah, when you are shooting in HDR you are capturing more brightness
:04:25. > :04:27.information so you don't get a washed out effect that you have with
:04:28. > :04:35.But with the new broadcast standard everything getting washed
:04:36. > :04:46.LG announced last week that 75% of its new TV sets this year would
:04:47. > :04:52.It's OLED screens will show even more detail in the darker ranges,
:04:53. > :04:55.it says, and it has teamed up with Dolby to support a sort
:04:56. > :05:03.Dolby Vision allows for even more details to be captured and displayed
:05:04. > :05:13.Now there is a rush to get content filmed in HDR to our screens.
:05:14. > :05:16.Amazon and Netflix have limited offerings
:05:17. > :05:21.and YouTube says it will be next, with broadcasters expected in 2017.
:05:22. > :05:25.And the new 4K BluRay disc players support both Dolby Vision
:05:26. > :05:32.With compatible TVs coming to shops this year in all
:05:33. > :05:35.but the smallest budget price ranges, the industry hopes will have
:05:36. > :05:52.Yeah, I was. darker screen.
:05:53. > :05:56.This is the first time I saw a 4K screen I thought I could
:05:57. > :06:03.I've had that experience once before watching an 8K screen but this 4K,
:06:04. > :06:11.It is just a shame we can't show the viewers at home what this sort
:06:12. > :06:16.But listen to this man, his word goes.
:06:17. > :06:18.You mentioned there were competing formats as well.
:06:19. > :06:26.Don't worry about the formats because they are
:06:27. > :06:32.Dolby Vision has the edge on specifics, specifications,
:06:33. > :06:34.and I can see a little bit of improvement over the blacks.
:06:35. > :06:38.Not a huge improvement on the industry standard, HDR10.
:06:39. > :06:41.Then there is the BBC standard, it is working on a broadcast
:06:42. > :06:44.standard all of its own that it will share with the industry, that way
:06:45. > :06:54.So one TV will be able to show all the formats.
:06:55. > :06:57.If it says it is HDR ready or compatible, that is fine.
:06:58. > :07:01.Will it cost more to buy these things?
:07:02. > :07:05.Interestingly, TVs are not going up in price.
:07:06. > :07:08.They are broadly the same as last year across the field.
:07:09. > :07:12.With HDR, what will cost you more money is when you stream
:07:13. > :07:21.Will I be able to watch much, has much been filmed for HDR already?
:07:22. > :07:26.The cameras we have had have been HDR compatible
:07:27. > :07:31.We have content, it just needs to come through the production system.
:07:32. > :07:35.Streaming services will start to offer them, including YouTube,
:07:36. > :07:41.We are also looking at the BluRay disks as well.
:07:42. > :07:50.Don't worry about that, new discs are coming out with this format on.
:07:51. > :07:53.And the BBC are working on that broadcast system which will deliver
:07:54. > :08:00.some sort of live broadcast, we think, next year or the year after.
:08:01. > :08:05.Just this week Netflix confirmed it has begun rolling out HDR to
:08:06. > :08:14.its movie and TV streaming services around the world.
:08:15. > :08:18.That said, the only thing that you can watch in HDR at the moment
:08:19. > :08:26.But to access them, viewers will need to to have
:08:27. > :08:34.Perhaps to lighten the blow, the service this week wheeled out
:08:35. > :08:47.a buffet of its stars, Ashton Kutcher is new to the table with his
:08:48. > :08:50.old 70's friend, Danny Masterson, who, with their new series,
:08:51. > :08:53.Their ability to distribute that content to a subset
:08:54. > :08:57.of the audience that is relevant to the piece of content you are
:08:58. > :09:01.creating allows more diverse stories over time from content creators.
:09:02. > :09:05.As it expands globally, Netflix will rely heavily on the
:09:06. > :09:08.secret recipe, the recommendation algorithm which customises each
:09:09. > :09:20.When you make a good algorithm, you have to take out all the rubbish
:09:21. > :09:24.We used to take age and gender because we thought it was important
:09:25. > :09:31.But now we think it is more important to
:09:32. > :09:38.Hello, and welcome to The Week in Tech.
:09:39. > :09:41.This was the week that we learned that Facebook is no longer just
:09:42. > :09:44.The company's new bot feature will see some new chatty friends
:09:45. > :09:49.The idea is that it will help you do things that you used to
:09:50. > :09:58.Right now the conversations are limited, so you can order flowers,
:09:59. > :10:05.Later on they hope that you can talk to them more naturally,
:10:06. > :10:10.Let's just hope they don't start sharing pictures of their lunch.
:10:11. > :10:13.And here's a trick you definitely should not try at home.
:10:14. > :10:17.The car company, Ford, has shown its driverless car driving
:10:18. > :10:20.in total darkness on its test track in Arizona.
:10:21. > :10:23.While the humans present had night vision goggle, the car used radar
:10:24. > :10:29.and very high resolution maps of the road layout to stay on course.
:10:30. > :10:32.Do you know that feeling when you have left some water
:10:33. > :10:36.on the other side of your spaceship but are worried you will crease
:10:37. > :10:43.Festo's free-motion handling autonomous flying gripping sphere is
:10:44. > :10:48.The drone can fly itself autonomously using indoor GPS and a
:10:49. > :10:52.pair of cameras and its soft plastic shell and sucker should mean that
:10:53. > :11:06.Welcome, everybody, to the world's first 360 immersive video.
:11:07. > :11:13.The first surgery to be filmed in 360 degree virtual reality
:11:14. > :11:19.streamed on-line for anyone to watch anywhere in the world.
:11:20. > :11:23.The medical students can see anything happening
:11:24. > :11:26.in the operating theatre from the perspective of a 360 degree
:11:27. > :11:34.This is the operating theatre number one of the Royal Sheffield Hospital.
:11:35. > :11:43.Dr Ahmed is removing a tumour from the patient's colon He is also
:11:44. > :11:46.a self-confessed geek and is passionate
:11:47. > :11:54.about using this technology to help train a new generation of surgeons.
:11:55. > :11:57.Students don't always have access to surgery so we have to find
:11:58. > :12:01.People around the world can use low-cost
:12:02. > :12:02.technology to immerse themselves in operation thatres around
:12:03. > :12:07.Dr Ahmed's company required a special player to enable live
:12:08. > :12:13.streaming and in the future the developers hope for more features.
:12:14. > :12:16.We would love an option for live chatting so the students
:12:17. > :12:19.can ask questions to the doctor and the surgeon can respond to them
:12:20. > :12:31.The doctor explains to his students as he does
:12:32. > :12:43.It's such a great opportunity for people who would not normally
:12:44. > :12:47.be able to see such an operation to learn from it.
:12:48. > :12:51.If you are there in person you won't be touching the patient, you are
:12:52. > :12:56.But now you can look over the patient instead of being
:12:57. > :13:05.The main selling point is that it puts you in places you would
:13:06. > :13:13.It is not as real as being here, but, whether you'd actually want to
:13:14. > :13:27.These big, lumbering beasts were once the future,
:13:28. > :13:33.but now they are in the past, thanks to disasters like this one.
:13:34. > :13:37.Flammable hydrogen, not such a great idea.
:13:38. > :13:40.Recently, we have started to see a renewed interest
:13:41. > :13:46.There was this helium filled thing which can be flown over crowds
:13:47. > :13:50.without the normal risk of those drone type injuries,
:13:51. > :13:59.There was a fine wind turbine, and this: The dragon dream,
:14:00. > :14:07.Now, LJ Rich has managed to get a look at something which is a kind
:14:08. > :14:10.of cross between an airship and a more traditional plane,
:14:11. > :14:16.something which is really about to take off .
:14:17. > :14:24.Welcome to the hangars of RAF Air Force base 50
:14:25. > :14:29.It is so big it has its own weather system and more than a few giant
:14:30. > :14:40.airships have glided out in storms over the years.
:14:41. > :14:50.Originally developed for the US summer by a British company,
:14:51. > :14:55.It is an airship, but not as we know it.
:14:56. > :14:57.Its distinctive shape has certainly been a talking point.
:14:58. > :14:59.That rotund shape fundamentally changes how the air moves around it.
:15:00. > :15:03.It is a hybrid airship which has a lot in common with traditional
:15:04. > :15:16.60% of our lift comes from buoyant lift.
:15:17. > :15:24.We also get up to 40% of our lift from having an aerodynamic shape,
:15:25. > :15:33.so the air going over the whole body of the aircraft.
:15:34. > :15:37.The wing shape gets it into the air and allows it to fly.
:15:38. > :15:41.That allows us to have the control ability of an aircraft and allows
:15:42. > :15:49.us to land very easily without lots of ground crew
:15:50. > :15:52.It's this, the landing, which gets people excited
:15:53. > :16:03.Like car, it just needs somewhere 1.5 times its size to touch down.
:16:04. > :16:06.It removes the need for an airport to get it in the air.
:16:07. > :16:09.The company hopes that the next version may even remove
:16:10. > :16:13.Simply by carrying its own mast, this flying machine could set
:16:14. > :16:17.down virtually anywhere, no matter how remote.
:16:18. > :16:24.I don't know what it is, I just want to be next to it.
:16:25. > :16:27.It's not every day that you come across a cuddly flying machine,
:16:28. > :16:34.But don't be fooled, there are over 30,000 cubic metres
:16:35. > :16:46.Up here is very rigid, this doesn't actually have a structure.
:16:47. > :16:49.It's reasonably rigid because of all the gas inside.
:16:50. > :17:01.Because of the design, this hybrid airship is greener
:17:02. > :17:04.compared to a fixed wing aircraft, using over two thirds less fuel over
:17:05. > :17:09.a comparable flight, but journeys take a lot longer.
:17:10. > :17:12.I could not take the ship up unaccompanied, but I was given
:17:13. > :17:19.After some instruction from a professional pilot,
:17:20. > :17:26.Turn to the right, lift it to the left.
:17:27. > :17:33.The Navy guys who come here are quite happy with it.
:17:34. > :17:37.A normal pilot would not recognise this.
:17:38. > :17:40.The first real-life use is likely to be cargo, up to ten tons.
:17:41. > :17:45.The next model will be able to carry five times that.
:17:46. > :17:49.But no matter how pleasant journey, just one of these costs over
:17:50. > :17:57.?325 million to make, that's $35 million.
:17:58. > :18:03.It leaves some people wondering if this mode of travel will ever
:18:04. > :18:07.I'm about to land my simulated airship, my approach speed
:18:08. > :18:14.I will just get a little bit lower...
:18:15. > :18:22.Then it should probably come to a halt on its own,
:18:23. > :18:28.Hopefully not bouncing around the passengers in the back.
:18:29. > :18:30.A couple of people might have spelt their tea,
:18:31. > :18:32.but otherwise I think that landing was reasonably good.
:18:33. > :18:49.Stay airborne for a few minutes, we first met the Jet Man in Dubai,
:18:50. > :19:00.the airline pilot who built himself a wing that allows him to do this.
:19:01. > :19:03.Until recently, he's had the skies to himself,
:19:04. > :19:06.but now he's got company up there in the clouds.
:19:07. > :19:16.Jet Man's training centre is based outside of Dubai.
:19:17. > :19:20.Today, I will watch him do his thing up close.
:19:21. > :19:29.In this hangar, they maintain the jet wings which are capable
:19:30. > :19:36.The wings need constant maintenance, he lacks to test them
:19:37. > :19:52.We change the engine to bigger ones, and we perform.
:19:53. > :20:10.He is a three-time world champion skydiver.
:20:11. > :20:13.I would see what he was doing as a pilot
:20:14. > :20:30.But you're alone, you can't share your emotions
:20:31. > :20:42.Outside the hangar, things are getting a bit noisy.
:20:43. > :20:53.This is why we got up early, Allied has arrived.
:20:54. > :20:57.With the chopper on the flight line, it is time for him to become Jet
:20:58. > :21:00.No flight would be complete without an
:21:01. > :21:15.As well as lacking doors, this particular vehicle lacks seats
:21:16. > :21:27.So, he's getting ready to launch the helicopter.
:21:28. > :21:32.His concentration looks absolutely total.
:21:33. > :21:35.With good reason, it he's got a wing on his back
:21:36. > :22:31.That is without a doubt the most amazing thing I've ever seen.
:22:32. > :22:35.We can to see him in the distance, his formation with the helicopter.
:22:36. > :22:37.There he is, flying with the helicopter right now.
:22:38. > :22:48.He's got about eight minutes worth of fuel.
:22:49. > :22:53.We definitely got the best seats in the house.
:22:54. > :23:08.But he is going to land using a slightly different method.
:23:09. > :23:37.As a trouble goes, it wasn't the most comfortable
:23:38. > :23:40.of rides but the in-flight entertainment was something else.
:23:41. > :23:42.They have plans to add another Jet Man to the line-up,
:23:43. > :23:47.so soon there might be a mini squadron.
:23:48. > :23:49.These guys will be taking to the skies.
:23:50. > :23:51.Those guys are, what's the technical term?
:23:52. > :23:54.You can see more on that story online.
:23:55. > :24:03.You can follow us for more tech news throughout the week.
:24:04. > :24:33.Thanks for watching, we would love to see you soon.
:24:34. > :24:35.Hello. A big shock to the system for many
