:00:32. > :00:37.Ask because I'm just wondering how good your pixels are.

:00:38. > :00:42.I'm not asking how many you got, just how good they are.

:00:43. > :00:44.See, there are many ways to improve your TV picture.

:00:45. > :00:47.One is to improve the resolution, how many pixels you have.

:00:48. > :00:50.That is why standard def is not as good as high-def,

:00:51. > :00:55.which in turn doesn't look as good as ultrahigh def.

:00:56. > :00:57.But, another way to improve the picture

:00:58. > :01:09.is to increase the colour depth, the level of detail in the colours.

:01:10. > :01:12.Over the past year, one or two top-end TVs have started

:01:13. > :01:16.to offer a new format which some are daring to call a game-changing

:01:17. > :01:23.They are calling it "High Dynamic Range," HDR,

:01:24. > :01:27.and this year it is set to be a thing on many new industry TVs.

:01:28. > :01:31.But is it just industry puff, or is it really time to buy a new TV

:01:32. > :01:37.We asked Dan Simmons to find out what HDR is, what it does,

:01:38. > :01:45.What interests me is what it looks like.

:01:46. > :01:48.Now, if that's going to have ten letters and numbers behind it,

:01:49. > :01:57.so be it, but I wouldn't be able to tell you what they are.

:01:58. > :02:00.I don't think many people know about High Dynamic Range itself.

:02:01. > :02:02.Most people when they first see it take a step

:02:03. > :02:08.Because sometimes to them it looks to them as if the person is actually

:02:09. > :02:16.Ted has been selling TVs for 18 years.

:02:17. > :02:20.He says it is a big deal so I have come to the HQ of Sony to

:02:21. > :02:37.And you won't be able to see this because you are watching in HD

:02:38. > :02:46.What more am I going to get from something called HDR?

:02:47. > :02:49.That's what we have set up on this TV, you can see

:02:50. > :02:53.HDR is the new broadcasting standard which gives you much more colour

:02:54. > :02:59.and brightness information compared to regular 4K.

:03:00. > :03:02.These are both 4K pictures but this one has High Dynamic Range.

:03:03. > :03:05.For example, you can see the skin tones are much

:03:06. > :03:17.HDR cameras capture colour information using a longer ten bit

:03:18. > :03:33.So more colour hues are available, making things look more real.

:03:34. > :03:35.For the first time, these TVs can play that back.

:03:36. > :03:39.Our eyes can see a huge spectrum of brightness, about 15 stops' worth.

:03:40. > :03:41.But up until now TVs have had a problem

:03:42. > :03:46.The picture burns out too easily or dark bits lose detail, for example.

:03:47. > :03:49.HDR delivers 85% of what most of us can see, resulting in a picture that

:03:50. > :03:53.holds on to the darker detail, even when bright lights are in shot.

:03:54. > :03:59.And in here, look at all that detail in the trees.

:04:00. > :04:07.And these suns, one is quite big and the other is much smaller.

:04:08. > :04:10.Is that something you get when you shoot in HDR?

:04:11. > :04:13.Yeah, when you are shooting in HDR you are capturing more brightness

:04:14. > :04:16.information so you don't get a washed out effect that you have with

:04:17. > :04:20.But with the new broadcast standard everything getting washed

:04:21. > :04:36.LG announced last week that 75% of its new TV sets this year would

:04:37. > :04:39.It's OLED screens will show even more detail in the darker ranges,

:04:40. > :04:42.it says, and it has teamed up with Dolby to support a sort

:04:43. > :04:55.Dolby Vision allows for even more details to be captured and displayed

:04:56. > :05:00.Now there is a rush to get content filmed in HDR to our screens.

:05:01. > :05:01.Amazon and Netflix have limited offerings

:05:02. > :05:04.and YouTube says it will be next, with broadcasters expected in 2017.

:05:05. > :05:07.And the new 4K BluRay disc players support both Dolby Vision

:05:08. > :05:29.With compatible TVs coming to shops this year in all

:05:30. > :05:32.but the smallest budget price ranges, the industry hopes will have

:05:33. > :05:35.HDR then, the better, brighter, darker screen.

:05:36. > :05:59.The first surgery to be filmed in 360 degree virtual reality

:06:00. > :06:01.streamed on-line for anyone to watch anywhere in the world.

:06:02. > :06:03.The medical students can see anything happening

:06:04. > :06:06.in the operating theatre from the perspective of a 360 degree

:06:07. > :06:10.This is the operating theatre number one of the Royal Sheffield Hospital.

:06:11. > :06:13.Dr Ahmed is removing a tumour from the patient's colon He is also

:06:14. > :06:15.a self-confessed geek and is passionate

:06:16. > :06:17.about using this technology to help train a new generation of surgeons.

:06:18. > :06:21.Students don't always have access to surgery so we have to find

:06:22. > :06:24.People around the world can use low-cost

:06:25. > :06:26.technology to immerse themselves in operation thatres around

:06:27. > :06:41.Dr Ahmed's company required a special player to enable live

:06:42. > :06:44.streaming and in the future the developers hope for more features.

:06:45. > :06:46.We would love an option for live chatting so the students

:06:47. > :06:50.can ask questions to the doctor and the surgeon can respond to them

:06:51. > :06:58.The doctor explains to his students as he does

:06:59. > :07:03.It's such a great opportunity for people who would not normally

:07:04. > :07:06.be able to see such an operation to learn from it.

:07:07. > :07:10.If you are there in person you won't be touching the patient, you are

:07:11. > :07:14.But now you can look over the patient instead of being

:07:15. > :07:19.The main selling point is that it puts you in places you would

:07:20. > :07:23.It is not as real as being here, but, whether you'd actually want to

:07:24. > :07:41.Staying airborne for a few minutes, we first met the Jetman Yves Rossy

:07:42. > :07:43.in Dubai, the airline pilot who built himself

:07:44. > :07:48.Until recently, he's had the skies to himself, but now he's

:07:49. > :07:59.Jetman's training centre is based outside of Dubai, today I will

:08:00. > :08:04.In this hangar, they maintained the jet wings which

:08:05. > :08:08.The wings need constant maintenance, he likes to test them up

:08:09. > :08:28.We changed the engine to bigger ones, and we perform.

:08:29. > :08:52.He is a three-time world champion skydiver.

:08:53. > :08:56.I would see what he was doing as a pilot and as a pioneer

:08:57. > :09:19.But you're alone, you can't share your emotions

:09:20. > :09:25.Outside the hangar, things are getting a bit noisy.

:09:26. > :09:28.This is why we got up early, our ride has arrived.

:09:29. > :09:31.With the chopper on the flight line, it is time for him to become Jetman.

:09:32. > :09:34.No flight would be complete without an inspirational soundtrack.

:09:35. > :09:38.As well as lacking doors, this particular vehicle lacks seats

:09:39. > :09:51.So, he's getting ready to launch the helicopter.

:09:52. > :09:53.His concentration looks absolutely total.

:09:54. > :09:55.With good reason, he's got a wing on his back with

:09:56. > :10:46.That is without a doubt the most amazing thing I've ever seen.

:10:47. > :10:49.We can to see him in the distance, his formation with the helicopter.

:10:50. > :10:51.There he is, flying with the helicopter right now.

:10:52. > :11:11.He's got about eight minutes worth of fuel.

:11:12. > :11:14.We definitely got the best seats in the house.

:11:15. > :11:35.But he is going to land using a slightly different method.

:11:36. > :11:44.They have plans to add another Jetman to the line-up, so soon there

:11:45. > :11:47.might be a mini squadron of these guys taking to the skies.

:11:48. > :11:52.That is it for the short Click this week, the longer one is on line.

:11:53. > :11:57.Thank you for watching. See you soon.
