This is bbc news, our latest headlines commentator Lizzie Yarnold goes to the front Lizzy Yarnold becomes the first british winter athlete to defend an olympic title after winning gold in the womens skeleton laura deas took bronze. Earlier izzy atkin won bronze in the womens ski slopestyle, a first ever medal for britain on skis. Theresa may warns European Union leaders not to put lives at risk by blocking a security deal after brexit. The Prime Minister said britain would no longer be able to help europol, as it does, or extradite suspects quickly. Ukip members are to vote on whether to back or sack henry bolton as party leader. The Partys National executive committee backed a vote of no confidence in him last month, after his former girlfriend had sent a series of racist messages. The president of haiti says the sex scandal involving some 0xfam workers may be just the tip of the iceberg. Jovenel moise says hes concerned that medecins sans frontiers has repatriated some staff without any explanation. Now on bbc news its time for click fashionably late, apple has decided it wants a slice of the home speaker market, finally releasing its homepod, some two and a half years after the first generation amazon echo hit the shelves. Theyve gone for the same cylindrical shape as both the google home and the amazon echo, but it feels and looks more like a premium high end speaker than either of those systems. Thats one of the key points here. The amount of audio work that apple have done on this device means its key selling point is as a speaker. It is impressive, with a four inch, upward facing woofer and seven beam forming tweeters, each with its own amplifier, meaning it can push sounds in different directions. So it sounds exactly the same wherever you are in the room. What it doesnt do is give you the opportunity to change the levels in any way. If i wanted to push the bass up right now, theres no way of me doing that. And even in a space this big, the sound really carries. Whats interesting, though, is even at 100 volume when i cant even hear myself think, siris still going to recognise my voice. Hey, siri, pause. Just like that. Whereas apple is going to sound quality, amazon, with their years on the market, seem to be focusing on different features. Their echo spot is all about one thing this screen. The latest from amazon now has the ability to make video calls, as well as doing the usual like play music, tell you the weather and even boil your kettle if youve got a smart home setup. But really it comes into its own as a very nice alarm clock. Its notjust a function that makes these two home assistants very different the price is anotherfactor. While the echo spot costs £119, the homepod will set you back £319. As is apples way, the homepod ties you in to apples walled garden, so, instead of being able to access any Music Streaming Service via voice activation, for example, it will only let you use apple music in this way. So if youre one of the 70 million spotify subscribers, you have to go into your phone and use airplay as a workaround, essentially turning this Premium Smart speaker into a, well, speaker. And, as people have been discovering, one that might leave a nasty white mark on wooden tops. Apples response . Choose a different surface, or get a cloth and some elbow grease. Now, over the next few weeks, were going to be talking to some of the gods of the visual affects world. Last week, we went behind the scenes of blade runner 20119. This week it is the turn of the 0scar nominated guardians of the galaxy volume 2, and we started by talking about its truly bonkers opening sequence. There aint a cloud in sight. The beginning of the sequence features a title sequence where groot is dancing in the foreground, and it doesnt cut, so it is on groot the whole time. Hes got to hold the attention of the viewers with his crazy little dance, whilst what happens in the background never stops. So we have Something Like 4,000 frames of continuous action. We were faced with the fact that the environment was completely spectacular and had to be created entirely digitally. Everything that we were inserting had to be reflected, and thats multiple times the computation to compute the light for whats landing on them but also their reflection, and so everything ended up being done two or three times, because of the surface of the world they were standing on. We were delighted to have the opportunity to take on rocket the raccoon. The fur shaders that weve got here at framestore, the muscle systems, all of these things had updated in the three years between the first guardians and this one. So, we wanted to bring all of that into rocket, which meant rebuilding him from the ground up, and yet making sure that he was absolutely recognisable as the same character from the first movie. Space being very open, its very hard to tell how fast things are moving. James gunn is very keen on selling the speed of the action. So, we conceived of these sort of wafts and waves of Plasma Energy that lived in and around this planet, which we could whip past the camera to really sell how fast the camera and the spaceships were all moving. Every movie that we get involved in, we want to be pushing the envelope, trying something new, with the expectation that we are going to get there. Old film stock is a treasure trove of historical information. In the case of old bbc programmes, it can be a race against time to find any remaining copy and digitise it or risk losing it forever. But when producer Charles Norton was given an old morecambe and wise episode, there was a problem. Archivists at both the bbc in the British Film Institute had a look at the film and essentiallyjudged it to be unable to be recovered. They were effectively saying it was going to be thrown out. The pictures inside that film, they are still there, theyre still printed on the plastic, but they are all locked inside this permanently fused block of immobile gunk, which, sooner or later, will just rot away to soup. So charles brought the film to queen mary universitys dental department to use that x ray machine to see through the lump of decaying film to the precious pictures within. But now they had another problem the film was too big to be x rayed. The only thing you could do would be to cut the film into little pieces and scan one piece at a time. I didnt expect him to say yes to cutting up the film, but given the alternative was watching this just rapidly disintegrate, he said, yeah, lets do it. We were using an infrared laser. It generated a lot of heat, and occasionally there were flames. At the best, we had a little bit of damage at the edge of the frames at worst, we lost whole frames. They took 5,000 images of each chunk as it rotated through 360 degrees to make a 3 d model. At that point, they started to see what was on the film for the first time. When you first start seeing those pictures of Eric Morecambe in one of his stereotypical poses, you cant help but smile and think, yes, this has to be done. Once the scans were finished, they had loads of data, but they also had a new problem. The next really difficult part was finding a way of digitally flattening out this warped object and digitally prising apart all of the individual film layers within it. We originally had the Manual Software where i would physically go through each individual block and spend five or ten minutes flattening out one layer after the other, but that was, over several thousand frames, quite labour intensive. At this Point Charles took the problem to a data scientist. What a human would do is try to see where the image was within the cross section. The problem here is that a computer algorithm cannot quite do that. What the algorithm does is it follows, predominantly, the layers of plastic, so not the images, but the plastic. So once we have the layer of plastic, we can move to the edge of that layer and read off the image. That process was repeated on all of the film, making short work of a task that would take a human thousands of hours of work. Now charles is beginning the next phase, turning these scarred pictures back into video. That is the next problem. But now he has managed to put together a taster of what is on that film. And beautifully as well. Not a word out of sync. Im not miming now. You realise, of course, that the tape has stopped. How does he do it . That is an impressive sight. That is the kings library, assembled by king george iii in the second half of the 18th century. Four floors below my feet here at the British Library lie its vast basements, which as you can imagine also contain a lot of books. But did you know they also contain 6. 5 million sound recordings which are now being digitised . The British Library is the national sound archive, with sound recordings spanning the last 130 years. These are stored on all sorts of physical formats, from delicate wax cylinders to brass discs, to short lived formats like minidisks, remember those . There is a big push to digitise them and make them available online. Each of the a0 different types of storage format has unique challenges. They all need their own playback devices, and some need a little tlc to coax the best quality sound from them. Something reasonably robust like a vinyl disc, we have an ultrasonic bath to be able to shake that debris out of its hiding place. We also have the more traditional type of record cleaning machines, the brush and vacuum arrangements, that can produce some quite startling results when you start to clean off otherwise invisible gunk. The team also have a workshop to keep their collection of machines in tiptop condition, so staff can work on as many concurrent transfers as possible and chip away at the millions of recordings. If you are faced with a tape or a disc in a really perilous state and you take it off a shelf, it may be mouldy, it may need treatment, some sort of repair, but doing that process, that active process of conserving and repairing that media such that it can be replayed, evenjust once, is hugely rewarding. Certainly challenging. But with only 2 of their collection digitised and only 15 years until some recordings become unsalvageable, it is a race against time to save as many as possible. It reminds me that i have a box full of minidisks in the loft i should bring them in. That is it for this week from the British Library. The long version is on the iplayer right now. Dont forget we are on facebook and on twitter bbcclick. Thank you very much for watching. We will see you soon. Just a reminder of events that have emerged in the last hour, initial reports of possible tremors around western england, the midlands and south wales which have been confirmed by the British Geological survey as a small earthquake that is what they have been showing on their website by way of confirmation. In terms of where and how large, the epicentre is 20 kilometres north east of swansea and the magnitude was quoted as 4. 4 and a depth of 7. 4 kilometres and it happened within the last hour. Events of this magnitude only happen in the uk about every 2 3 years and if you are watching just before half past you will have heard a conversation i had with eight woman a woman at to swansea who felt walls moving and a loud sound for about 20 seconds and neighbours nearby felt the same. We will keep a close eye on that for any further reaction. Two members of the same family, a 15 year old boy and a 72 year old man were killed when a train collided with a car at a level crossing in horsham in west sussex will British Transport Police confirming that two members of the same family have died, a 15 year old boy and a 72 year old man. That is in horsham, west sussex. More now on one of our main stories this lunchtime and theresa may has urged European Union leaders not to put lives at risk by blocking a security deal after brexit because of deep seated ideology. The Prime Minister was speaking at a security conference in munich. Mrs may said that that nothing must get in the way of britain and the eu helping each other to keep people safe. The Prime Minister said that real political will is required to safeguard Intelligence Co operation which has developed over the decades. People across europe are safer because of this cooperation and the unique arrangements we have developed between the uk and eu institutions in recent years. So it is in all of our interests to find ways to protect the capabilities that underpin this cooperation when the uk becomes a european country outside the eu, but in a new partnership with it. To make this happen will require real political will on both sides. I recognise there is no existing Security Agreement between the eu and a third country that captures the full depth and breadth of our existing relationship, but there is precedent for comprehensive strategic relationships between the eu and third countries in other fields, such as trade, and there is no legal or operational reason why such an agreement could not be reached in the area of internal security. However, if the priority in the negotiations becomes avoiding any kind of new cooperation with a country outside the eu, then this political doctrine and ideology will have damaging real world consequences for the security of all our people in the uk and the eu. Lets be clear about what would happen if the means of this cooperation were abolished. Extradition under the european arrest warrant would cease. Extradition outside the european arrest warrant can cost four times as much and take three times as long. It would mean an end to the Significant Exchange of data and engagement through europol and it would mean the uk would no longer be able to secure evidence from European Partners quickly through the european investigation order, with strict deadlines for gathering evidence requested. Instead, relying on slower more cumbersome systems. This would damage us both and would put all our citizens at greater risk. As leaders, we cannot let that happen. So we need together to demonstrate some real creativity and ambition to enable us to meet the challenges of the future as well as today. Thats why i have proposed a new treaty to underpin our future internal security relationship. The treaty must preserve our operational capabilities, but it must also fulfil three further requirements. It must be respectful of the sovereignty of both the uk and the eus legal orders. So, for example, when participating in eu agencies, the uk will respect the remit of the European Court ofjustice and a principled, but pragmatic solution to close legal co operation will be needed to respect our unique status as a third country with our own sovereign legal order. As ive said before, well need to agree a strong and appropriate form of independent dispute resolution across all the areas of our future partnership in which both sides can have the necessary confidence. We must also recognise the importance of comprehensive and robust Data Protection arrangements. The uks Data Protection law will ensure we are aligned with the eu framework, but we want to go further and seek a bespoke arrangement to reflect the uks exceptionally high standards of Data Protection. And we envisage an ongoing role for the uks information commissioners office, which would be beneficial in providing stability and confidence for eu and uk individuals and businesses alike. And we are ready to start working through this with colleagues in the European Commission now. 0ur chief Political Correspondent vicki young has been gauging reaction to the Prime Ministers speech. Her message was very much about the fa ct her message was very much about the fact that britain has a lot to offer when it comes to defence and security, so she came here but said she wanted to make an unconditional offer and you wanted to continue and there was a warning to eu leaders, saying dont let your ideology about eu institutions get in the way of this, we can have a special treaty and continued the very close cooperation. We can discuss this more with the conservative mpjohnny mercer. What did you make of the speech . I thought it was very good, and she is right, we need to Start Talking turkey on this stuff and being pretty hard ball when it comes to security, because we have a lot to security, because we have a lot to offer when it comes to security and you can see the figures that we contribute to nato, that we are a significant player in European Defence and it is important to remember that. Defence and it is important to rememberthat. Im defence and it is important to remember that. Im struck by the lack of accept and said the eu votes thatis lack of accept and said the eu votes that is going on out here, that has been interesting and the Prime Minister was right to knock that back. That was mentioned by a german diplomat, saying it would be so much easier if you just said in the eu and the audience applauded. Is there and the audience applauded. Is there an larger mad that she is asking for an larger mad that she is asking for a complete continuation of everything we have got . Is their an argument. I can see that side of the item about the british people have decided to leave the eu and she has got to be robust with that, she has got to be robust with that, she has got to represent the people who voted for her and the conservative government, we have got to start getting into the detail of this. We can improve our offer around defence and security and we need to have another look in the uk as to how we prioritise security but she did really well today, i thought. It has beena really well today, i thought. It has been a Good Conference for the Prime Minister. Johnny mercer, thanks for joining us. Theresa may, the second ina joining us. Theresa may, the second in a series of speeches and then of course a rather crucial meeting with senior cabinet ministers late in the week where they will have to try and thrash out some kind of compromise about our future relationship with the eu. The brazilian government has given the military full control to oversee security in rio dejaneiro in response to growing gang violence. Rios governor issued an appeal for help as the annual carnival celebrations were marred by violence. Stefan levy reports. From this. To this. Just a week from the beginning of this years rio carnival. Despite thousands of police on the street during the annual celebrations a series of armed robberies and confrontations between rival gangs shone a spotlight on the citys deteriorating security situation. Tourist areas usually considered safe had been transformed into a hotbed of crime and violence. 0n friday the brazilian president michael temer signed a decree giving the military full control of Security Operations in rio. Translation organised crime has virtually taken control of the state of Rio De Janeiro virtually taken control of the state of rio dejaneiro and it is a state which has extended to the country and threatens the tranquillity of oui and threatens the tranquillity of our nation and for that reason we have called for a federal intervention into Public Security for Rio De Janeiro. The army already patrol some of the most dangerous areas of the city where drug gangs operate but now their presence will be felt all over rio, the situation unheard of since brazils return to democracy in 1985 after 21 years of military rule. Rios Police Budget has been slashed in recent years because of economic crisis and finances in the state have been badly hit by a National Recession and a slump in oil prices as well as high levels of alleged corruption. Michael temers decree is expected to be approved by the national c0 ng ress to be approved by the National Congress next week and with it hope amongst local people that something is being done. It is now time for the weather forecast. It isa it is a weekend of two halves, and for many the best of the sunshine today, certainly the case in guernsey, but not everyone has seen the sunshine and there has been more cloud ramdin faces which has brought showers stash around in places. This cloud has been bringing rain in northern and central england. There isa northern and central england. There is a weakening feature so what we will find is that the cloud will break and they will be spells of sunshine and the rain will melt away. Though the evening, clear skies, through the evening. Under clear skies it will be a cold and frosty night with temperatures at or just below freezing, problems with mist and fog especially in the northern england. As the name implies, behind it is milder air represented by the yellow colours. We have the milder air making inroads into the cold air, the blue colours, which we have seen in the last few days. Tomorrow, a different feel to the weather, cloudy with outbreaks of rain, but feeling milder. Sunday morning, dry and bright and frosty especially in eastern areas but cloud will be building further west and that will bring outbreaks of rain eased through the day. East. Highs tomorrow 7 11, feeling milder than it has done recently. The band of cloud and rain continues on its journey east through tomorrow evening and some eastern areas might not see the rain until after dark but eventually it becomes cloudy and murkier and there will be missed and fog and we will keep outbreaks of rain as we go into monday. Some of thatis rain as we go into monday. Some of that is likely to linger in eastern and south eastern parts. We start the week mild but it doesnt last for very long, because slowly yellow colours start to disappear as to the west, north westerly winds every pick up the easterly wind and notice how the blue colours will be betting colder. After a mild damp start, we pick up those easterly winds and it sta rts pick up those easterly winds and it starts to turn colder but it should remain fairly dry. This is bbc news.
