This week, eye-popping colours, formation madness, | :00:00. | :00:09. | |
Ask because I'm just wondering how good your pixels are. | :00:10. | :00:44. | |
I'm not asking how many you got, just how good they are. | :00:45. | :00:53. | |
See, there are many ways to improve your TV picture. | :00:54. | :00:56. | |
One is to improve the resolution, how many pixels you have. | :00:57. | :00:58. | |
That is why standard def is not as good as high-def, | :00:59. | :01:02. | |
which in turn doesn't look as good as ultrahigh def. | :01:03. | :01:05. | |
But, another way to improve the picture | :01:06. | :01:07. | |
is to increase the colour depth, the level of detail in the colours. | :01:08. | :01:13. | |
Over the past year, one or two top-end TVs have started | :01:14. | :01:16. | |
to offer a new format which some are daring to call a game-changing | :01:17. | :01:19. | |
They are calling it "High Dynamic Range," HDR, | :01:20. | :01:28. | |
and this year it is set to be a thing on many new industry TVs. | :01:29. | :01:32. | |
But is it just industry puff, or is it really time to buy a new TV | :01:33. | :01:36. | |
We asked Dan Simmons to find out what HDR is, what it does, | :01:37. | :01:43. | |
What interests me is what it looks like. | :01:44. | :01:56. | |
Now, if that's going to have ten letters and numbers behind it, | :01:57. | :01:59. | |
so be it, but I wouldn't be able to tell you what they are. | :02:00. | :02:04. | |
I don't think many people know about High Dynamic Range itself. | :02:05. | :02:07. | |
Most people when they first see it take a step | :02:08. | :02:10. | |
Because sometimes to them it looks to them as if the person is actually | :02:11. | :02:16. | |
Ted has been selling TVs for 18 years. | :02:17. | :02:26. | |
He says it is a big deal so I have come to the HQ of Sony to | :02:27. | :02:30. | |
And you won't be able to see this because you are watching in HD | :02:31. | :02:45. | |
What more am I going to get from something called HDR? | :02:46. | :02:55. | |
That's what we have set up on this TV, you can see | :02:56. | :02:58. | |
HDR is the new broadcasting standard which gives you much more colour | :02:59. | :03:02. | |
and brightness information compared to regular 4K. | :03:03. | :03:05. | |
These are both 4K pictures but this one has High Dynamic Range. | :03:06. | :03:10. | |
For example, you can see the skin tones are much | :03:11. | :03:15. | |
HDR cameras capture colour information using a longer ten bit | :03:16. | :03:26. | |
So more colour hues are available, making things look more real. | :03:27. | :03:33. | |
For the first time, these TVs can play that back. | :03:34. | :03:37. | |
Our eyes can see a huge spectrum of brightness, about 15 stops' worth. | :03:38. | :03:42. | |
But up until now TVs have had a problem | :03:43. | :03:45. | |
The picture burns out too easily or dark bits lose detail, for example. | :03:46. | :03:52. | |
HDR delivers 85% of what most of us can see, resulting in a picture that | :03:53. | :03:57. | |
holds on to the darker detail, even when bright lights are in shot. | :03:58. | :04:05. | |
And in here, look at all that detail in the trees. | :04:06. | :04:13. | |
And these suns, one is quite big and the other is much smaller. | :04:14. | :04:18. | |
Is that something you get when you shoot in HDR? | :04:19. | :04:21. | |
Yeah, when you are shooting in HDR you are capturing more brightness | :04:22. | :04:24. | |
information so you don't get a washed out effect that you have with | :04:25. | :04:27. | |
But with the new broadcast standard everything getting washed | :04:28. | :04:35. | |
LG announced last week that 75% of its new TV sets this year would | :04:36. | :04:46. | |
It's OLED screens will show even more detail in the darker ranges, | :04:47. | :04:52. | |
it says, and it has teamed up with Dolby to support a sort | :04:53. | :04:55. | |
Dolby Vision allows for even more details to be captured and displayed | :04:56. | :05:03. | |
Now there is a rush to get content filmed in HDR to our screens. | :05:04. | :05:13. | |
Amazon and Netflix have limited offerings | :05:14. | :05:16. | |
and YouTube says it will be next, with broadcasters expected in 2017. | :05:17. | :05:21. | |
And the new 4K BluRay disc players support both Dolby Vision | :05:22. | :05:25. | |
With compatible TVs coming to shops this year in all | :05:26. | :05:32. | |
but the smallest budget price ranges, the industry hopes will have | :05:33. | :05:35. | |
Yeah, I was. darker screen. | :05:36. | :05:52. | |
This is the first time I saw a 4K screen I thought I could | :05:53. | :05:56. | |
I've had that experience once before watching an 8K screen but this 4K, | :05:57. | :06:03. | |
It is just a shame we can't show the viewers at home what this sort | :06:04. | :06:11. | |
But listen to this man, his word goes. | :06:12. | :06:16. | |
You mentioned there were competing formats as well. | :06:17. | :06:18. | |
Don't worry about the formats because they are | :06:19. | :06:26. | |
Dolby Vision has the edge on specifics, specifications, | :06:27. | :06:32. | |
and I can see a little bit of improvement over the blacks. | :06:33. | :06:34. | |
Not a huge improvement on the industry standard, HDR10. | :06:35. | :06:38. | |
Then there is the BBC standard, it is working on a broadcast | :06:39. | :06:41. | |
standard all of its own that it will share with the industry, that way | :06:42. | :06:44. | |
So one TV will be able to show all the formats. | :06:45. | :06:54. | |
If it says it is HDR ready or compatible, that is fine. | :06:55. | :06:57. | |
Will it cost more to buy these things? | :06:58. | :07:01. | |
Interestingly, TVs are not going up in price. | :07:02. | :07:05. | |
They are broadly the same as last year across the field. | :07:06. | :07:08. | |
With HDR, what will cost you more money is when you stream | :07:09. | :07:12. | |
Will I be able to watch much, has much been filmed for HDR already? | :07:13. | :07:21. | |
The cameras we have had have been HDR compatible | :07:22. | :07:26. | |
We have content, it just needs to come through the production system. | :07:27. | :07:31. | |
Streaming services will start to offer them, including YouTube, | :07:32. | :07:35. | |
We are also looking at the BluRay disks as well. | :07:36. | :07:41. | |
Don't worry about that, new discs are coming out with this format on. | :07:42. | :07:50. | |
And the BBC are working on that broadcast system which will deliver | :07:51. | :07:53. | |
some sort of live broadcast, we think, next year or the year after. | :07:54. | :08:00. | |
Just this week Netflix confirmed it has begun rolling out HDR to | :08:01. | :08:05. | |
its movie and TV streaming services around the world. | :08:06. | :08:14. | |
That said, the only thing that you can watch in HDR at the moment | :08:15. | :08:18. | |
But to access them, viewers will need to to have | :08:19. | :08:26. | |
Perhaps to lighten the blow, the service this week wheeled out | :08:27. | :08:34. | |
a buffet of its stars, Ashton Kutcher is new to the table with his | :08:35. | :08:47. | |
old 70's friend, Danny Masterson, who, with their new series, | :08:48. | :08:50. | |
Their ability to distribute that content to a subset | :08:51. | :08:53. | |
of the audience that is relevant to the piece of content you are | :08:54. | :08:57. | |
creating allows more diverse stories over time from content creators. | :08:58. | :09:01. | |
As it expands globally, Netflix will rely heavily on the | :09:02. | :09:05. | |
secret recipe, the recommendation algorithm which customises each | :09:06. | :09:08. | |
When you make a good algorithm, you have to take out all the rubbish | :09:09. | :09:20. | |
We used to take age and gender because we thought it was important | :09:21. | :09:24. | |
But now we think it is more important to | :09:25. | :09:31. | |
Hello, and welcome to The Week in Tech. | :09:32. | :09:38. | |
This was the week that we learned that Facebook is no longer just | :09:39. | :09:41. | |
The company's new bot feature will see some new chatty friends | :09:42. | :09:44. | |
The idea is that it will help you do things that you used to | :09:45. | :09:49. | |
Right now the conversations are limited, so you can order flowers, | :09:50. | :09:58. | |
Later on they hope that you can talk to them more naturally, | :09:59. | :10:05. | |
Let's just hope they don't start sharing pictures of their lunch. | :10:06. | :10:10. | |
And here's a trick you definitely should not try at home. | :10:11. | :10:13. | |
The car company, Ford, has shown its driverless car driving | :10:14. | :10:17. | |
in total darkness on its test track in Arizona. | :10:18. | :10:20. | |
While the humans present had night vision goggle, the car used radar | :10:21. | :10:23. | |
and very high resolution maps of the road layout to stay on course. | :10:24. | :10:29. | |
Do you know that feeling when you have left some water | :10:30. | :10:32. | |
on the other side of your spaceship but are worried you will crease | :10:33. | :10:36. | |
Festo's free-motion handling autonomous flying gripping sphere is | :10:37. | :10:43. | |
The drone can fly itself autonomously using indoor GPS and a | :10:44. | :10:48. | |
pair of cameras and its soft plastic shell and sucker should mean that | :10:49. | :10:52. | |
Welcome, everybody, to the world's first 360 immersive video. | :10:53. | :11:06. | |
The first surgery to be filmed in 360 degree virtual reality | :11:07. | :11:13. | |
streamed on-line for anyone to watch anywhere in the world. | :11:14. | :11:19. | |
The medical students can see anything happening | :11:20. | :11:23. | |
in the operating theatre from the perspective of a 360 degree | :11:24. | :11:26. | |
This is the operating theatre number one of the Royal Sheffield Hospital. | :11:27. | :11:34. | |
Dr Ahmed is removing a tumour from the patient's colon He is also | :11:35. | :11:43. | |
a self-confessed geek and is passionate | :11:44. | :11:46. | |
about using this technology to help train a new generation of surgeons. | :11:47. | :11:54. | |
Students don't always have access to surgery so we have to find | :11:55. | :11:57. | |
People around the world can use low-cost | :11:58. | :12:01. | |
technology to immerse themselves in operation thatres around | :12:02. | :12:02. | |
Dr Ahmed's company required a special player to enable live | :12:03. | :12:07. | |
streaming and in the future the developers hope for more features. | :12:08. | :12:13. | |
We would love an option for live chatting so the students | :12:14. | :12:16. | |
can ask questions to the doctor and the surgeon can respond to them | :12:17. | :12:19. | |
The doctor explains to his students as he does | :12:20. | :12:31. | |
It's such a great opportunity for people who would not normally | :12:32. | :12:43. | |
be able to see such an operation to learn from it. | :12:44. | :12:47. | |
If you are there in person you won't be touching the patient, you are | :12:48. | :12:51. | |
But now you can look over the patient instead of being | :12:52. | :12:56. | |
The main selling point is that it puts you in places you would | :12:57. | :13:05. | |
It is not as real as being here, but, whether you'd actually want to | :13:06. | :13:13. | |
These big, lumbering beasts were once the future, | :13:14. | :13:27. | |
but now they are in the past, thanks to disasters like this one. | :13:28. | :13:33. | |
Flammable hydrogen, not such a great idea. | :13:34. | :13:37. | |
Recently, we have started to see a renewed interest | :13:38. | :13:40. | |
There was this helium filled thing which can be flown over crowds | :13:41. | :13:46. | |
without the normal risk of those drone type injuries, | :13:47. | :13:50. | |
There was a fine wind turbine, and this: The dragon dream, | :13:51. | :13:59. | |
Now, LJ Rich has managed to get a look at something which is a kind | :14:00. | :14:07. | |
of cross between an airship and a more traditional plane, | :14:08. | :14:10. | |
something which is really about to take off . | :14:11. | :14:16. | |
Welcome to the hangars of RAF Air Force base 50 | :14:17. | :14:24. | |
It is so big it has its own weather system and more than a few giant | :14:25. | :14:29. | |
airships have glided out in storms over the years. | :14:30. | :14:40. | |
Originally developed for the US summer by a British company, | :14:41. | :14:50. | |
It is an airship, but not as we know it. | :14:51. | :14:55. | |
Its distinctive shape has certainly been a talking point. | :14:56. | :14:57. | |
That rotund shape fundamentally changes how the air moves around it. | :14:58. | :14:59. | |
It is a hybrid airship which has a lot in common with traditional | :15:00. | :15:03. | |
60% of our lift comes from buoyant lift. | :15:04. | :15:16. | |
We also get up to 40% of our lift from having an aerodynamic shape, | :15:17. | :15:24. | |
so the air going over the whole body of the aircraft. | :15:25. | :15:33. | |
The wing shape gets it into the air and allows it to fly. | :15:34. | :15:37. | |
That allows us to have the control ability of an aircraft and allows | :15:38. | :15:41. | |
us to land very easily without lots of ground crew | :15:42. | :15:49. | |
It's this, the landing, which gets people excited | :15:50. | :15:52. | |
Like car, it just needs somewhere 1.5 times its size to touch down. | :15:53. | :16:03. | |
It removes the need for an airport to get it in the air. | :16:04. | :16:06. | |
The company hopes that the next version may even remove | :16:07. | :16:09. | |
Simply by carrying its own mast, this flying machine could set | :16:10. | :16:13. | |
down virtually anywhere, no matter how remote. | :16:14. | :16:17. | |
I don't know what it is, I just want to be next to it. | :16:18. | :16:24. | |
It's not every day that you come across a cuddly flying machine, | :16:25. | :16:27. | |
But don't be fooled, there are over 30,000 cubic metres | :16:28. | :16:34. | |
Up here is very rigid, this doesn't actually have a structure. | :16:35. | :16:46. | |
It's reasonably rigid because of all the gas inside. | :16:47. | :16:49. | |
Because of the design, this hybrid airship is greener | :16:50. | :17:01. | |
compared to a fixed wing aircraft, using over two thirds less fuel over | :17:02. | :17:04. | |
a comparable flight, but journeys take a lot longer. | :17:05. | :17:09. | |
I could not take the ship up unaccompanied, but I was given | :17:10. | :17:12. | |
After some instruction from a professional pilot, | :17:13. | :17:19. | |
Turn to the right, lift it to the left. | :17:20. | :17:26. | |
The Navy guys who come here are quite happy with it. | :17:27. | :17:33. | |
A normal pilot would not recognise this. | :17:34. | :17:37. | |
The first real-life use is likely to be cargo, up to ten tons. | :17:38. | :17:40. | |
The next model will be able to carry five times that. | :17:41. | :17:45. | |
But no matter how pleasant journey, just one of these costs over | :17:46. | :17:49. | |
?325 million to make, that's $35 million. | :17:50. | :17:57. | |
It leaves some people wondering if this mode of travel will ever | :17:58. | :18:03. | |
I'm about to land my simulated airship, my approach speed | :18:04. | :18:07. | |
I will just get a little bit lower... | :18:08. | :18:14. | |
Then it should probably come to a halt on its own, | :18:15. | :18:22. | |
Hopefully not bouncing around the passengers in the back. | :18:23. | :18:28. | |
A couple of people might have spelt their tea, | :18:29. | :18:30. | |
but otherwise I think that landing was reasonably good. | :18:31. | :18:32. | |
Stay airborne for a few minutes, we first met the Jet Man in Dubai, | :18:33. | :18:49. | |
the airline pilot who built himself a wing that allows him to do this. | :18:50. | :19:00. | |
Until recently, he's had the skies to himself, | :19:01. | :19:03. | |
but now he's got company up there in the clouds. | :19:04. | :19:06. | |
Jet Man's training centre is based outside of Dubai. | :19:07. | :19:16. | |
Today, I will watch him do his thing up close. | :19:17. | :19:20. | |
In this hangar, they maintain the jet wings which are capable | :19:21. | :19:29. | |
The wings need constant maintenance, he lacks to test them | :19:30. | :19:36. | |
We change the engine to bigger ones, and we perform. | :19:37. | :19:52. | |
He is a three-time world champion skydiver. | :19:53. | :20:10. | |
I would see what he was doing as a pilot | :20:11. | :20:13. | |
But you're alone, you can't share your emotions | :20:14. | :20:30. | |
Outside the hangar, things are getting a bit noisy. | :20:31. | :20:42. | |
This is why we got up early, Allied has arrived. | :20:43. | :20:53. | |
With the chopper on the flight line, it is time for him to become Jet | :20:54. | :20:57. | |
No flight would be complete without an | :20:58. | :21:00. | |
As well as lacking doors, this particular vehicle lacks seats | :21:01. | :21:15. | |
So, he's getting ready to launch the helicopter. | :21:16. | :21:27. | |
His concentration looks absolutely total. | :21:28. | :21:32. | |
With good reason, it he's got a wing on his back | :21:33. | :21:35. | |
That is without a doubt the most amazing thing I've ever seen. | :21:36. | :22:31. | |
We can to see him in the distance, his formation with the helicopter. | :22:32. | :22:35. | |
There he is, flying with the helicopter right now. | :22:36. | :22:37. | |
He's got about eight minutes worth of fuel. | :22:38. | :22:48. | |
We definitely got the best seats in the house. | :22:49. | :22:53. | |
But he is going to land using a slightly different method. | :22:54. | :23:08. | |
As a trouble goes, it wasn't the most comfortable | :23:09. | :23:37. | |
of rides but the in-flight entertainment was something else. | :23:38. | :23:40. | |
They have plans to add another Jet Man to the line-up, | :23:41. | :23:42. | |
so soon there might be a mini squadron. | :23:43. | :23:47. | |
These guys will be taking to the skies. | :23:48. | :23:49. | |
Those guys are, what's the technical term? | :23:50. | :23:51. | |
You can see more on that story online. | :23:52. | :23:54. | |
You can follow us for more tech news throughout the week. | :23:55. | :24:03. | |
Thanks for watching, we would love to see you soon. | :24:04. | :24:33. | |
Hello. A big shock to the system for many | :24:34. | :24:35. |
