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.
