officers. Now it is time for Click. Mobile phones can be tracked. The

:00:03.:00:12.

internet can be monitored. So why can't be predicted a riot? -- Why

:00:12.:00:22.
:00:22.:00:26.

Can't We predict a right? We will look at the technology behind this

:00:26.:00:32.

week's riots. Just how much blame can we place on BlackBerry, Twitter

:00:32.:00:42.
:00:42.:00:44.

or Facebook. We take you on a journey into sound. All the latest

:00:44.:00:53.

tech news and webscape. Over the last week, England has seen the

:00:53.:00:58.

worst riots in living memory. What started as a protest at a police

:00:58.:01:02.

shooting of a young man in London quickly escalated into several

:01:02.:01:11.

nights of chaos. Shops were ransacked, police were attacked and

:01:11.:01:18.

buildings burned. Unlike previous disturbances and demonstrations

:01:18.:01:23.

this was not just one large mass of people moving through a city. Mops

:01:23.:01:27.

appeared to spring from the way before disappearing again only for

:01:27.:01:37.
:01:37.:01:38.

a different group to so bring up someone else. How did they know a

:01:38.:01:43.

way to meet and why did the police knocked me that? This is not the

:01:43.:01:47.

first time that mobile phones and social networks have been used to

:01:47.:01:53.

organise large crowds. We explained how Facebook had been used to build

:01:53.:01:58.

a groundswell of support for uprisings in North Africa and the

:01:58.:02:04.

Middle East and how Twitter had been used to disseminate

:02:04.:02:09.

instructions to protesters in London after they had begun. Any

:02:09.:02:13.

one, including the police, can monitor the chapter, as long as

:02:14.:02:19.

they are looking in the right place. This time the rioters used a more

:02:19.:02:24.

private way to get in message out, one which a boy did the days of the

:02:24.:02:34.
:02:34.:02:35.

authorities. -- avoided the view of the authorities. BlackBerry is the

:02:35.:02:40.

most popular phone among young people in the UK. That is partly

:02:40.:02:46.

down to the BlackBerry Messenger service. Only those invited to the

:02:46.:02:52.

group can read them. That makes it difficult for police to see what is

:02:52.:02:58.

being organised and spot clues as to where trouble might happen next.

:02:58.:03:04.

Messages are encrypted before they leave the handset and the data is

:03:04.:03:08.

transmitted to BlackBerry service in Canada before being sent on to

:03:08.:03:14.

the recipient devices over the mobile phone networks. One of the

:03:14.:03:18.

ways that have been communicating is by a BlackBerry Messenger

:03:18.:03:23.

because it cannot be traced and is difficult for the police to track.

:03:23.:03:28.

If it is technically possible I would like to see BlackBerry

:03:28.:03:33.

Messenger disabled from 6pm at night to 6am in the morning to stop

:03:33.:03:36.

the people co-ordinating these things from organising in the way

:03:36.:03:43.

they have been. In the UK we have something called the Regulation of

:03:43.:03:45.

investigatory Powers Act, Regulation of Investigatory Powers

:03:45.:03:50.

Act, which allows police to monitor communications in some

:03:50.:03:54.

circumstances. It is not a licence to sit through everyone's

:04:04.:04:12.

Communications. -- sift through. The maker of BlackBerry, RIM said:.

:04:12.:04:18.

We complied with the Regulation of investigatory Powers Act and co-

operate fully with police forces. They will already want to know his

:04:24.:04:34.
:04:34.:04:42.

records they want to see. -- whose records. In right situation, on

:04:43.:04:49.

dark nights with covered faces, surely it should be possible to use

:04:49.:04:56.

technology to trace those involved. One lawyer, a former advisor to the

:04:56.:04:59.

government on covert policing, says it is far more difficult than you

:04:59.:05:07.

might think. They are no doubt it responsible commercial entity that

:05:07.:05:16.

will want to with this the police. It is questionable inveigled hands

:05:16.:05:22.

whether they can offer that. It may be a breach of the Data Protection

:05:22.:05:31.

Act. The Mutual Assistance Agreement is engaged and it becomes

:05:31.:05:37.

more bureaucratic, time consuming and problematic. In the next few

:05:37.:05:41.

weeks we will find out it ANA chronic evidence helps the police

evidence. The government has promised to look into whether it

:05:53.:05:57.

would be right to stop people communicating by social media if

:05:57.:06:04.

they know it there are putting social disruption. This is not

:06:04.:06:11.

simply a demonstration of how social media can wreak havoc. As

:06:11.:06:15.

events quickly unfolded local forums and services like Twitter

:06:15.:06:20.

helped to keep some Londoners aware of rioting in their area. One

:06:20.:06:25.

social media experts used his skills to post an inner piloting

:06:35.:06:36.

the trouble spots. I started to put some of the riots on a Google Maps

:06:36.:06:41.

and work out what they were. Quickly it became apparent the were

:06:41.:06:48.

riots in different parts of London. So will I thought that we needed to

:06:48.:06:53.

add this to work out that people could share with other people and

:06:53.:06:59.

work out what was actually a right and what was a remark. Discounting

:06:59.:07:04.

and sit in fact from online fiction almost requires the skills they did

:07:04.:07:09.

it will detected. Some people were reporting that tanks were coming

:07:09.:07:15.

into London. That was a message about tanks in Egypt from four

:07:15.:07:19.

months ago. The difficulty is that you do not know whether something

:07:19.:07:27.

is true or false. I was involved in making sure that established news

:07:27.:07:34.

organisations were reporting on the same thing. I checked local

:07:34.:07:42.

newspapers and saw what people wrote in their own blocks. And

:07:42.:07:45.

seeing whether lots of different people were talking about the same

:07:45.:07:49.

thing in different ways. The police have also turned to

:07:49.:07:57.

social media hoping to identify rioters and looters. They posted

:07:57.:08:05.

CCTV images on their website and Flickr. In a matter of a was the

morning and writers last night. A thing that sends a very powerful

:08:36.:08:46.

message. With me is the editor up of a take block, Mike Butcher.

Should we be blaming the technology you? You can use it to make good

:09:07.:09:15.

phone calls or bad for an calls. It is a power using the technology to

:09:15.:09:25.

amplify an existing situation. At the same time social media and the

BlackBerry can be used to bring the community together. How realistic

:09:30.:09:36.

is it that BlackBerry Messenger could be shut down at particular

Facebook has launched its own Messenger this week. It works

:12:17.:12:24.

report them. We all none at least one of them.

:12:24.:12:31.

You may very well be one of them. I am talking about audio files,

:12:31.:12:36.

people who spend a disproportionate amount of time and money in the

:12:36.:12:40.

pursuit of sound perfection. Have you wondered whether these people

:12:40.:12:44.

are wasting their money? There are small things anyone can do to

:12:44.:12:48.

improve the quality of their sound system without blowing get that

:12:48.:12:58.

balance. We have been looking at the evolution of home audio. The

:12:58.:13:03.

breathtaking sounds of a live orchestra. Everyone is aiming for

:13:03.:13:11.

one thing. The hairs on the back of unit. A bunch of musicians in your

:13:11.:13:17.

living room may be impractical, but that is the idea when you listen to

:13:17.:13:23.

a recording of the BBC Philharmonic. And her wit his record it is the

:13:23.:13:29.

first state of high quality sound reproduction. The equipment is

:13:29.:13:37.

formidable. The thing in the middle records the whole orchestra. Other

:13:37.:13:43.

microphones report each individual instrument in case it needs a boost.

:13:43.:13:48.

We have a sound maestro who has the best years in the business. All the

:13:48.:13:53.

microphones are patched into imports in the floor. They are

:13:53.:14:00.

converted into digital signals. The whole thing is digitised and then

:14:00.:14:07.

we arrived at the centre of the studio, which is these sound desk.

:14:07.:14:11.

When setting up your system, if the speakers are not pointing to your

:14:11.:14:18.

ears, you name is the top notes. The speakers are designed for the

:14:18.:14:25.

person sitting at the desk. Even at the back of the control room miss a

:14:25.:14:31.

lot of those high frequencies. I asked them to come over here and it

:14:31.:14:41.
:14:41.:14:45.

These days there are many soundbox. But there is a special kind of

:14:45.:14:49.

audiophile bat spends above and beyond most of us. Welcome to high-

:14:49.:14:55.

end audio. You are looking at around �10,000 worth of speakers

:14:55.:15:03.

being made. High Speed Two coats each ranging different speaker

:15:03.:15:12.

frequencies. there are projections of how loudspeakers may behave

:15:12.:15:21.

before even building them. That is his and a colleague or echoless

:15:21.:15:27.

chamber - -- chamber. He still has to spend a lot of time testing

:15:27.:15:32.

prototypes. The more we can spend on it, materials and construction

:15:32.:15:37.

and research and development, the closer we can get the idea of this

:15:37.:15:41.

perfect Speaker with a beautifully flat frequency response, without

:15:42.:15:50.

any Cabinet coloration. He is trying to get better stereo imaging.

:15:50.:15:55.

But the biggest obstacle is space which this acoustic professor is

:15:55.:15:59.

all too aware of. You do not get the true sound of the orchestra

:15:59.:16:02.

because the living room you have to put the sound through is nothing

:16:02.:16:06.

like a concert hall and you cannot take that out of the equation. It

:16:06.:16:10.

will bounce off the walls and you will hear the effects and

:16:10.:16:13.

reflections. So you have an augmentation of the sound that

:16:13.:16:17.

would never happen in a real concert hall. So it always sounds

:16:17.:16:22.

different are the real space. You can get rid of those imperfections

:16:22.:16:27.

by putting in the could mean. Or perhaps scatter the sound. So put

:16:27.:16:33.

things that would make the sound bounced off in different directions.

:16:33.:16:38.

That can be specialist material or things like bookcases. That makes

:16:38.:16:42.

the groom appeared eager. Because your living room is too small and

:16:42.:16:51.

the reflections arrive early. If they arrive early, you can get them

:16:51.:16:54.

to bat in different directions are we to Piers bigger. There is more

:16:54.:17:00.

take on the way. These people think it is worth going back in time to

:17:01.:17:05.

search for the sound of the future. One idea that has been around since

:17:05.:17:11.

the 70s is a wave field synthesis system. A circle of a one UN -- of

:17:11.:17:15.

a number of deer hide speakers that creates a surround-sound blanket.

:17:15.:17:20.

In this case, it is a cafe. Listeners inside feel they can

:17:20.:17:27.

point directly at a source. It laughs in the face of me a stereo.

:17:27.:17:33.

Stereo at home is very simply... It relies on the feeling that

:17:33.:17:40.

something is moving in the sound field. Stereo also depends on this

:17:40.:17:45.

idea of experience in the sound desk between the speakers. We have

:17:45.:17:55.

a large sound -- large space where people can experience that feeling.

:17:55.:18:00.

Currently, this system could set you back about �200,000. But this

:18:00.:18:04.

kid only cost one-tenth of that and is running on a household PC. This

:18:04.:18:10.

step closer to home. But assuming you do not have time or space for

:18:10.:18:16.

128 because, how about just 14? Another all be but goody has been

:18:16.:18:21.

given a modern twist. With six speakers at the height, and four on

:18:21.:18:26.

the ceiling and four on the floor, sound can be placed anywhere. This

:18:26.:18:30.

demonstration used as a connect Controller to help you move it

:18:31.:18:37.

around. We are looking at have been 5.1 surround-sound. In the future

:18:37.:18:42.

you might want three-dimensional sound. So we are looking at the

:18:43.:18:46.

only a new level of experience into the mix. In this set-up, the

:18:47.:18:50.

computer works out how to direct the sound once you tell it where

:18:50.:18:55.

the speakers are. This is still some years from mass-production.

:18:55.:19:03.

But the sound processing programmes can be down that -- downloaded. It

:19:03.:19:08.

can be used with only one speaker as well. It is a great example of

:19:08.:19:12.

how the quest for perfect sound reproduction always comes back to

:19:12.:19:16.

individual preference. Of course, everybody hears the world Evenley

:19:16.:19:22.

but one thing experts agree on is how to buy a ticket. Try it and if

:19:22.:19:29.

you like it, buy it. Just do not get our reporter

:19:33.:19:38.

Here on Click, we are always receding links. You suggest them on

:19:38.:19:42.

e-mail or post them online. The problem is, we never know were

:19:42.:19:48.

there a link is safe to click on. If it comes from an unknown source,

:19:48.:19:52.

the best thing to do is pass it on to Kate Russell who can take it out

:19:52.:19:57.

for you. A good rule of thumb for the

:19:57.:20:01.

internet is be careful where you put your mouse pointer. You never

:20:01.:20:11.
:20:11.:20:11.

know what might be lurking behind that harmless looking URL. Viruses

:20:11.:20:18.

are always a potential risk if you do not recognise the sender of the

:20:18.:20:21.

link. Even your friends can send you something nasty if they have

:20:22.:20:27.

been infected with the virus themselves. That is why you might

:20:27.:20:35.

want to bookmark this link. Feed this website a URL and it will spit

:20:35.:20:41.

out a report that you can rely on. It is free and easy to use which is

:20:41.:20:48.

great when you consider how much heartache it can save you. Some PC

:20:48.:20:51.

security programmes Oprah this feature as well but if yours does

:20:51.:21:00.

not, this is a good free alternative. -- offer. So feel you

:21:00.:21:04.

need never suffer from viruses again.

:21:04.:21:09.

I showed you an online contact card last month and now I will go one

:21:09.:21:14.

better with a free business card up for your smartphone that led to

:21:14.:21:23.

share contact instantly. Set up and leading your social account is very

:21:23.:21:30.

easy and then you are ready to share. If you have somehow been

:21:30.:21:33.

transported back in time and the person you are trying to connect

:21:33.:21:37.

with does not have a mobile or at least the application installed,

:21:37.:21:42.

you can also e-mail it straight from your hand said. And it gives

:21:42.:21:47.

your meetings contexts, saving a GPS marker with a business card to

:21:47.:21:51.

remind you where you met. This information is also stalled on the

:21:51.:21:57.

dashboard along with any notes on meetings you want to add. It can be

:21:57.:22:07.
:22:07.:22:09.

very handy with the terrible memory I have. It isn't everything but

:22:09.:22:14.

sometimes it is good to know how small something years, especially

:22:14.:22:22.

when it comes to mobile technology. This website is not particularly

:22:22.:22:26.

sophisticated but when you tell it the size of your monitor, it will

:22:26.:22:30.

display items in their real size. If you are feeling generous, you

:22:30.:22:39.

can help build the database by adding the size. My head is not

:22:40.:22:49.
:22:50.:22:50.

that be, you know. -- beak. While the UK is preoccupied with news

:22:50.:22:53.

about the looting, it is worth remembering there are other

:22:54.:22:58.

important stories as well. Like the crisis unfolding in East Africa.

:22:58.:23:07.

Social media can be powerful in these cases to. As shown at

:23:07.:23:17.

forecast you want at this time of year but we lose the bulk of the

:24:36.:24:41.

wet weather and it is a slow improvement this weekend. After a

disappointing start, it may Brighton today. Bright rather than

:24:47.:24:56.

sunny. There may be some rain Deraa -- towards the south-east. It will

be a mild start to our weekend across the UK, particularly across

:25:04.:25:08.

central and eastern areas. It will be another warm and humid feel want

:25:08.:25:13.

the news that rain to the south- east corner. Already we can see the

:25:13.:25:18.

improvement along the Dorset coast and through the Isle of Wight. To

:25:18.:25:24.

London at 9am, it will be cloudy, grey and wet. The same for East

:25:24.:25:28.

Anglia. There will be an improvement eventually. Glimpses of

:25:29.:25:32.

sunshine to the east of the Pennines. The cloud and rain that

:25:32.:25:37.

is clearing from the Northern Isles. A wet start. A few showers across

:25:37.:25:42.

western Scotland. A better morning in Northern Ireland but it will be

:25:42.:25:49.

cloudy. 13 degrees expected with a light breeze. Cloud for Wales. It

:25:49.:25:57.

will be a rainy morning. We are optimistic the crowd will tend to

:25:57.:26:05.

live and bright and somewhat in one or two places as the rain eases.

:26:05.:26:10.

Some sunny spells. With some sunshine coming through, it will

:26:10.:26:18.

feel humid in the south-eastern corner. Temperatures around 21-23

:26:18.:26:26.

degrees. Further west, stubborn thicker cloud resulting in lower

:26:26.:26:34.

temperatures. There may be drizzly showers but on the whole, not a bad

:26:34.:26:44.

affair. Taking a look at Saturday, the Kent coast baby affected with

:26:44.:26:49.

drizzly weather. But we are hopeful of sunshine coming through on

:26:49.:26:56.

Click goes behind the technology that helped to organise this week's riots in the UK. How much were social media sites to blame for the trouble ? And is it possible to silence them?
