Ask because I'm just wondering how good your pixels are.

I'm not asking how many you got, just how good they are.

See, there are many ways to improve your TV picture.

One is to improve the resolution, how many pixels you have.

That is why standard def is not as good as high-def,

which in turn doesn't look as good as ultrahigh def.

But, another way to improve the picture

is to increase the colour depth, the level of detail in the colours.

Over the past year, one or two top-end TVs have started

to offer a new format which some are daring to call a game-changing

They are calling it "High Dynamic Range," HDR,

and this year it is set to be a thing on many new industry TVs.

But is it just industry puff, or is it really time to buy a new TV

We asked Dan Simmons to find out what HDR is, what it does,

What interests me is what it looks like.

Now, if that's going to have ten letters and numbers behind it,

so be it, but I wouldn't be able to tell you what they are.

I don't think many people know about High Dynamic Range itself.

Most people when they first see it take a step

Because sometimes to them it looks to them as if the person is actually

Ted has been selling TVs for 18 years.

He says it is a big deal so I have come to the HQ of Sony to

And you won't be able to see this because you are watching in HD

What more am I going to get from something called HDR?

That's what we have set up on this TV, you can see

HDR is the new broadcasting standard which gives you much more colour

and brightness information compared to regular 4K.

These are both 4K pictures but this one has High Dynamic Range.

For example, you can see the skin tones are much

HDR cameras capture colour information using a longer ten bit

So more colour hues are available, making things look more real.

For the first time, these TVs can play that back.

Our eyes can see a huge spectrum of brightness, about 15 stops' worth.

But up until now TVs have had a problem

The picture burns out too easily or dark bits lose detail, for example.

HDR delivers 85% of what most of us can see, resulting in a picture that

holds on to the darker detail, even when bright lights are in shot.

And in here, look at all that detail in the trees.

And these suns, one is quite big and the other is much smaller.

Is that something you get when you shoot in HDR?

Yeah, when you are shooting in HDR you are capturing more brightness

information so you don't get a washed out effect that you have with

But with the new broadcast standard everything getting washed

LG announced last week that 75% of its new TV sets this year would

It's OLED screens will show even more detail in the darker ranges,

it says, and it has teamed up with Dolby to support a sort

Dolby Vision allows for even more details to be captured and displayed

Now there is a rush to get content filmed in HDR to our screens.

Amazon and Netflix have limited offerings

and YouTube says it will be next, with broadcasters expected in 2017.

And the new 4K BluRay disc players support both Dolby Vision

With compatible TVs coming to shops this year in all

but the smallest budget price ranges, the industry hopes will have

HDR then, the better, brighter, darker screen.

The first surgery to be filmed in 360 degree virtual reality

streamed on-line for anyone to watch anywhere in the world.

The medical students can see anything happening

in the operating theatre from the perspective of a 360 degree

This is the operating theatre number one of the Royal Sheffield Hospital.

Dr Ahmed is removing a tumour from the patient's colon He is also

a self-confessed geek and is passionate

about using this technology to help train a new generation of surgeons.

Students don't always have access to surgery so we have to find

People around the world can use low-cost

technology to immerse themselves in operation thatres around

Dr Ahmed's company required a special player to enable live

streaming and in the future the developers hope for more features.

We would love an option for live chatting so the students

can ask questions to the doctor and the surgeon can respond to them

The doctor explains to his students as he does

It's such a great opportunity for people who would not normally

be able to see such an operation to learn from it.

If you are there in person you won't be touching the patient, you are

But now you can look over the patient instead of being

The main selling point is that it puts you in places you would

It is not as real as being here, but, whether you'd actually want to

Staying airborne for a few minutes, we first met the Jetman Yves Rossy

in Dubai, the airline pilot who built himself

Until recently, he's had the skies to himself, but now he's

Jetman's training centre is based outside of Dubai, today I will

In this hangar, they maintained the jet wings which

The wings need constant maintenance, he likes to test them up

We changed the engine to bigger ones, and we perform.

He is a three-time world champion skydiver.

I would see what he was doing as a pilot and as a pioneer

But you're alone, you can't share your emotions

Outside the hangar, things are getting a bit noisy.

This is why we got up early, our ride has arrived.

With the chopper on the flight line, it is time for him to become Jetman.

No flight would be complete without an inspirational soundtrack.

As well as lacking doors, this particular vehicle lacks seats

So, he's getting ready to launch the helicopter.

His concentration looks absolutely total.

With good reason, he's got a wing on his back with

That is without a doubt the most amazing thing I've ever seen.

We can to see him in the distance, his formation with the helicopter.

There he is, flying with the helicopter right now.

He's got about eight minutes worth of fuel.

We definitely got the best seats in the house.

But he is going to land using a slightly different method.

They have plans to add another Jetman to the line-up, so soon there

might be a mini squadron of these guys taking to the skies.

That is it for the short Click this week, the longer one is on line.

Thank you for watching. See you soon.
