With the World Motorsport Council adding India in next year’s Formula One calendar, motorsports enthusiasts in India can look forward to the Indian GP at Greater Noida in October next year.The Formula One track (in circle) in Greater Noida.The track of the Indian GP, promoted by Jaypee Sports International, has been designed by German designer Hermann Tilke and the promoters are confident that the $ 350 million project will be grand success.”We realised that we have to make the track right. We shared the design of track with few of the top teams and their drivers.They put the design in their simulators and advised us about the changes that would the circuit more challenging. And we made those changes. It will be a great driver’s track,” Mark Hughes, vice-president, operations, JPSI told Mail Today. The track is 5.14km long with 16 corners. It has been built on 350 hectares of land with the fastest corners on Turn 10 and 11. Apart from F1, there are plans to have MotoGp and World Superbike series here too.
A sign reading “YOU ARE NOT FORGOTTEN” in front of the POW-MIA seat at Ohio Stadium. Credit: @OhioStAthleticsIt’s a seat, but not any seat. Unlike other seats, which are meant to be sat in, no one will sit in it. Not on Saturday when the Ohio State football team opens its 2016 season against Bowling Green at Ohio Stadium. Not any on Saturday, or the week’s other six days. No, no one will ever sit in this seat, because this seat, it’s more than a seat. The seat is in the first row of section 3AA at the stadium. It’s in that section, surrounded by the some 100,000 frenzied other fans wearing Scarlet and Gray and the usual sliver of opposing fans wearing whatever colors of whatever team they support, that members of the ROTC program at Ohio State, donning their branch’s respective uniforms, sit during football games. This seat, unveiled for the first time Thursday, is black. It’s not for Buckeye fans. It’s not for opposing fans. It’s not for any of us. This stirring black seat is a memorial for the 92,000 American soldiers that are unaccounted since World War I, the war that was supposed to end all wars. If looking at the seat from the front, in the upper right-hand corner, it’s marked seat No. 1, for the 92,000. In the middle of the forever-empty seat’s back is the harrowing POW/MIA logo — the silhouette of a man’s head in the foreground, with a guard tower and a barbed-wire fence in the background. The rest of the seats at Ohio Stadium are mostly bleachers. The bottom rung, closest to the green astroturf, are steel gray. The ones beyond that are scarlet. That pattern — rows of gray, rows of scarlet, rows of gray — spiral upward until the stadium stops and the sky begins. Smattered throughout the vast stadium, disrupting that perfect scarlet-and-gray spiral, are scarlet chairs, for the season ticket holders. But on game day, what those seats look like, no one knows; it doesn’t matter. The seats in the stadium, whether it be for the meaningless spring scrimmage, the banal early-season matches versus weaker teams or the wintery late-season contests, are, it seems, always occupied.This POW-MIA seat will remain empty the entire season at Ohio Stadium. Credit: @OhioStAthleticsExcept this black seat will never be occupied. Though it has a backing like the scarlet chairs season-ticket holders sit in, this is quite literally one-of-a-kind. It shall always serve as a reminder that whatever a game’s outcome is, at the end of the day, it’s just sports, which are important, but not that important. On the gray railing in front of the empty black seat is a black rectangular plaque, with a thin-gray trim. In large gray font, it reads: “YOU ARE NOT FORGOTTEN.” Below, it continues: “Since World War I, more than 92,000 American soldiers are unaccounted for. This unoccupied seat is dedicated to the memory of these brave men and women and to the sacrifices each made in serving this country. God Bless You. God Bless America.” Sometime around noon on Saturday, the kicker for either Bowling Green or Ohio State will send a football flying through the blue September sky. Well over a 100,000 fans, wearing a collection of scarlet and gray, orange and brown, or their ROTC uniform, will leave their seats, making noise, as the game gets under way.But in the first row of section 3AA, there will be a tiny space where no noise is coming from, near the black seat, in which no one is sitting.
Junior midfielder Ellyn Gruber (5) fights off a defender during a match against Purdue Sept. 29 at Jesse Owens Memorial Stadium. OSU lost, 1-0.Credit: Michele Theodore / Copy chiefAs the Ohio State women’s soccer team (8-3-3, 2-2-2) heads to State College, Pa., to play No. 17 Penn State, it has to prepare to face its second ranked opponent in its last three scheduled matches.Coach Lori Walker said she understands the importance of this match for the Buckeyes.“(Playing) at Penn State is always a great challenge,” Walker said. “It’s going to be a battle, and you know, we’ve just got to take it minute by minute. I (have) got to make sure my A-team gets on that bus.”The Buckeyes won their last match Saturday, ending a three-game scoreless streak in the process, by finding the back of the net three times in a win against Michigan State.“It was a huge weight off our shoulders,” said junior midfielder Ellyn Gruber. “We (had) been working all week on (finishing), a lot of repetition and stuff, so it finally gave us some confidence.”OSU started the year at No. 23, peaking at No. 21, but fell out of the polls after losing to Boston College 1-0 Sept. 5, despite beating Northeastern 4-1 Sept. 8. The Buckeyes currently sit eighth in the Big Ten and if the team wants to move up the standings, it has to start with improved finishing offensively, sophomore forward Michela Paradiso said.“We just gotta continue to work harder in practice and keep finishing, cause that can give us confidence that we can keep putting goals up on the board,” Paradiso said after Saturday’s game.At 10-3-1 overall and 4-2-0 in Big Ten matches, the Nittany Lions are currently third in conference play, sitting behind No. 22 Nebraska and No. 12 Michigan. The Nittany Lions are coming off a 1-0 home loss to the Wolverines Sunday, their first loss at home since the beginning of the 2012 season to Stanford.Offensively, senior forward Maya Hayes leads Penn State with 13 goals on the season, a mark that makes her second-best in the Big Ten.The Buckeyes lost their matchup last season with the Nittany Lions, a 3-0 decision at home, but Gruber said the Buckeyes will be ready this time around.“That’s going to be a huge, huge game. It’s going to be really tough, but we are just going to have a good, hard, week of practice, and we’ll be prepared,” Gruber said.The game is set for 3 p.m. Thursday.

Martin Keown voiced his opinion that ever since Mourinho arrived in the Premier League back in 2004, when he was the manager of Chelsea, Wenger’s career has turned upside down and he was not able to bounce back.Mourinho’s arrival at Stamford Bridge proved to be a turning point for Chelsea as well – he quickly went in on investing Roman Abramovich’s millions and turned Chelsea into a feared side in the Premier League as they battled United and Arsenal for the cup. The worst thing about it is that they succeeded.Former Gunners defender Keown shared that the rivalry between Wenger’s Arsenal and Mourinho’s Manchester United was the cherry on top of the cake.“Jose Mourinho became Arsene Wenger’s next big adversary and Wenger came off worse in that head-to-head,” Keown shared, according to Goal.Jose Mourinho is sold on Lampard succeeding at Chelsea Tomás Pavel Ibarra Meda – September 14, 2019 Jose Mourinho wanted to give his two cents on Frank Lampard’s odds as the new Chelsea FC manager, he thinks he will succeed.There really…“Mourinho coming in and winning those two Premier Leagues in 2005 and 2006 ultimately brought about the beginning of the end of Wenger’s supremacy in English football.”“His timing was perfect. He arrived at Chelsea with plenty of resources at his disposal and built a brilliant team. Arsenal finished second in 2005 and without the rise of Chelsea, Wenger probably would have won another Premier League title.”“I am sure both men will be eager to get one last victory over the other this weekend,” Keown went on to add.

American Business Media has released its year-end 2007 Business Information Network (BIN) numbers, the metrics that track advertising spending by category in b-to-b media. Totals show an overall revenue decline of 2 percent—not a strong finish in the face of a decidedly gloomy 2008 economy. And this after essentially finishing flat at the end of 2006. Among the 21 categories tracked, the steepest revenue declines were computing, software, telecom (-17.59 percent); business, advertising & marketing (-10.7 percent); and travel, business conventions & meetings (-6.95 percent).The top three gainers were resources, environment, utilities (12.72 percent); architecture, design, lighting (10.49 percent); and science, research and development (10.11 percent). A total of 13 categories showed revenue increases, but 9 of those were below 5 percent and many of those categories saw corresponding drops in page counts. Total spending across all categories for the year was $10.72 billion—down from year-end 2006 total spending of $10.94 billion.The total number of ad pages were also down 3.35 percent. The numbers erase a flat 2006, where the fourth quarter of that year wiped out decent gains through the third quarter. The year concluded with a 0.61 percent revenue “gain” over 2005. All hope now seems to rest on the revenues to be made in ancillary businesses such as e-media and events. ABM president and CEO Gordon Hughes emphasized these segments when he noted “continued industry growth” in a statement accompanying the results, pointing out that digital business has been growing “in excess” of 20 percent. ABM’s T-BIN numbers, which track trade show activity, recorded a 6.60 percent increase in revenues over 2006. ABM attempted to put a good face on the print results, going so far to suggest “ignoring” the computer, software, telecom category—the report’s top decliner. “In fact, ignoring the ‘Computing, Software, Telecom’ category would result in an overall 0 [percent] change over 2006,” contends ABM’s analysis. This of course begs the question of whether the rest of the declining categories should also be ignored.
Sophie TurnerGetty ImagesIs there trouble brewing in BFF paradise? Sophie Turner and Maisie Williams are best friends, but could it be that the pair is drifting apart? Sophie reportedly got married to Joe Jonas last week without inviting her best pal Maisie Williams.And now the Game of Thrones actress has dealt another blow apparently snubbing Maisie’s request to be her plus one at the premiere for forthcoming X-Men film, Dark Phoenix.Reportedly Sophie posted a tweet about a contest she’s involved with for Omaze, offering one fan the chance to attend the screening with her. ‘Want to be my plus-one at the Dark Phoenix premiere and hang with the X-Men cast? It’s all to support 4 incredible causes!’ she posted to the micro-blogging site.Maisie piped up, replying: ‘omg pick me pls.’To which Sophie responded: ‘Fat chance.’ Maisie Williams and Sophie TurnerGetty Images We have to say the pair had us worried for a second. But it looks like the exchange was in good fun and the two best friends are still very friendly. The pair play sisters on the hit HBO TV show Game of Thrones.Jean Grey is arguably one of the most powerful mutants out there and she is one of the biggest threats the X-Men have ever faced. X-Men: Dark Phoenix will hit theatres on June 20 2019. But fans will not have to wait that long to watch Sophie Turner as Sansa Stark on Game of Thrones. The fifth episode of the final season will air on May 12.
.UNESCO on Saturday added eight pre-Islamic Iranian archaeological sites to its World Heritage List, the UN agency announced at a meeting in the Bahraini capital.The sites collectively appear on the worldwide list as the “Sassanid Archaeological Landscape of Fars region (Islamic Republic of Iran)”.A province in modern-day Iran’s south, Fars was the cradle of the Sassanid dynasty, which appeared at the start of the third century.After the fall of the Parthian empire, the Sassanids ruled territory that, at its peak, stretched from the west of Afghanistan to Egypt, before falling to the Arab conquest under the Umayyad caliphate in the middle of the seventh century.”These fortified structures, palaces and city plans date back to the earliest and latest times of the Sassanian Empire,” UNESCO said.With the latest addition, Iran now has 24 sites on the heritage list of the United Nations Educational, Scientific and Cultural Organisation.
Story Links LOUISVILLE, Ky. – The Scott Satterfield era got underway as the University of Louisville football program reported Saturday to officially kick off the 2019 football season.The Cardinals reported for a 4 p.m. meeting with compliance before gathering together with the coaching staff and their families for a steak and chicken dinner in the Howard Schnellenberger Football Complex.”We’re excited to get going,” Satterfield said. “They guys have worked extremely hard. They have really changed their bodies, and a lot of the player have put on the right type of weight. We had a tremendous buy-in from everyone. We’re definitely a different football team.”Sunday will be the first time the new coaching staff will work together as a complete team since March when spring practice ended.Satterfield will conduct split practices on Sunday and Monday before the entire team comes together for the third day.The Red group will practice first from 4 p.m. to 5:30 p.m. and the Black team will work out at 5:30 p.m.”We have pushed our players extremely hard this summer, and they have responded every day,” Satterfield said. “I think Mike Sirignano and his staff did a great job with the players getting them stronger and faster.”The Cardinals return 17 starters from last season, but also have added a number of new faces, including six graduate transfers to help bolster the roster. Ean Pfiefer, T.J. McCoy, Thomas Jackson are new to the offense, T.J. Holl, Ty Tyler and Isiah Hayes are new names on defense that the first-year coach hopes will stabilize the team.”Because of a lack of depth, we’ve had to add to our roster,” Satterfield said. “It’s going to be a challenge to find the right guys for the right spots. We need to find roles for everyone. It’s going to take time to find the right roles for a lot of those guys, but I know those players will help us.”Satterfield wants the first couple of weeks to just be about his football team. While he knows his team has to prepare for a tough opening game against a top-10 opponent in Notre Dame, he wants to find out more about his football team.”We still have a lot to get done,” Satterfield said. “We have installed quite a bit on both sides of the ball, but we want to take this time to focus on getting better each day. We have a lot of work to put in over the next couple of weeks, but we will focus on Notre Dame about the last 8-10 days of camp.” Print Friendly Version
The energy harvesting chain shows how some energy is extracted from previously harvested energy, and injected in short pulses back into the piezoelectric element to increase the overall amount of harvested energy. The increase occurs due to an energy resonance effect. Image credit: Lallart and Guyomar. ©2010 American Institute of Physics. Energy harvesting often uses piezoelectric materials, which have the property of generating an electric field in the presence of an applied mechanical strain. As Lallart and Guyomar explain, piezoelectric materials usually have a low global coupling coefficient, corresponding to a low conversion ability. Although the coupling coefficient is an inherent property of a material, the scientists explained that they can artificially enhance the conversion abilities of piezoelectric materials by using a pulsed initial energy injection.In the proposed scheme, harvested energy is first extracted from the piezoelectric element via a microgenerator. The energy is then injected as a quick pulse back into the piezoelectric element through either its top or bottom electrode, resulting in a positive or negative voltage, respectively. The energy injection creates an “energy resonance” effect due to the pulsed energy feedback to the piezoelectric material. Due to this energy resonance effect, the initial energy injection to the piezoelectric material creates an overall energy gain that is higher than the energy initially extracted from the piezoelectric material. The researchers identified an optimal energy injection value, after which higher values create a damping effect on the piezoelectric material that results in a significant decrease in the mechanical energy available for harvesting. When optimized, the proposed design could allow a device to use much less piezoelectric material than a standard design, and still harvest the same amount of energy. “The main contribution of this work is to demonstrate that taking energy from the storage stage and transferring it to the source, although it seems counter-productive because of the losses in the transfer mechanism, can lead to outstanding performance in terms of power output,” Lallart told PhysOrg.com. “In particular, performing these operations in a pulsed fashion (i.e., providing initial energy to the active material) makes the technique easy to implement. One of the most remarkable things about this technique is its ability to bypass the power limit of all other techniques when considering the damping effect induced by the scavenging process (constant force magnitude case).” As the scientists explained, most previous methods for energy conversion enhancement have been “unidirectional,” meaning they don’t take advantage of using the energy generated from the device itself as input energy. The few previous methods that were “bidirectional” like the current design, using output energy for input energy, required constant driving of the device, resulting in a complex implementation and requiring a significant amount of energy for driving the system, which made them barely realistic. In contrast, the fact that the new method only requires quick pulses allows for an easier implementation and greatly reduces the driving energy. The energy extraction and injection processes are so much quicker than the device’s vibration time period that they can be considered instantaneous. For these reasons, the scientists predict that this approach could improve the amount of energy harvested by two, three, or four times compared with other methods aiming at increasing the power output, even at low energy extraction efficiencies.“The main motivations in energy harvesting research are explained by the growth of small-scale, low-power electronic devices, as well as the limitations of primary batteries that raise maintenance issues because of their limited lifespan and environmental problems due to their complex recycling process,” Lallart said. “Although the viability of self-powered systems has already been demonstrated, the functions of such devices are still limited by the available energy. Hence, the aim of research on energy harvesting is twofold. First, increasing the power output of microgenerators allows for implementing more functions in the self-powered device. Second, improvements in the conversion abilities of active materials would permit a significant reduction of the amount of material required to harvest a given amount of energy, allowing for the disposal of small-scale, embeddable devices.” Explore further (PhysOrg.com) — Harvesting mechanical energy from the environment and converting it into electrical energy has recently become a viable method for powering low-energy electronics, such as sensors and actuators. But the major drawback of energy harvesting is how little energy it generates, which limits its potential applications. In a new study, Mickael Lallart and Daniel Guyomar from the LGEF Laboratory at the University of Lyon have proposed that an initial energy injection extracted from the harvested energy itself could greatly increase the total energy output; specifically, this method could generate 20 times more energy than normal when using off-the-shelf components, and up to 40 times more when using low-loss devices.

© 2011 PhysOrg.com Explore further Expedition heads for world’s deepest undersea volcanoes Yeti crab. Image: Andrew Thurber (PhysOrg.com) — A research team sailing on the vessel James Cook has been studying the unique habitat surrounding deep sea vents in the Indian Ocean far off the south-east coast of Africa. The vents, created by under-the-sea-floor volcanic activity, spew black cloudy liquid and create a hot hostile environment. One of them, known as the Dragon Vent, was the main focus of cameras fixed to an aquatic robot that captured the existence of some of the exotic animals that are able to live in the distinctive environment. One of those creatures, a type of yeti crab, may even be a species unknown to science. 你需要安装能够查看此内容的 Adobe Flash Player。Please click here to continue.The expedition, sponsored by Britain’s Natural Environment Research Council and led by Dr. Jon Copley, a marine biologist, set sail from South Africa early in November and concluded its voyage this past week. During the middle part of that trip, the team sent down a robot called Kiel 6000 which has both cameras and a means for collecting samples of marine life, to the vents to see what sorts of animals might be living down there. Other such ventures to other vents in the Indian Ocean, as well as in other oceans have shown that truly unique types of creatures have evolved that are able to flourish in such a strange part of the planet. What’s not clear, however, is how such creatures manage to move the vast distances between such vents, as the vents, just like volcanoes on land, tend to go dormant between periods of activity.Other types of sea life found around vents include sea cucumbers, which are long and skinny and are related to sea stars and unique types of snails, shrimp and mussels.The vents in this latest study, are part of the South West Indian Ridge, and were first noted in 2007 by a team of Chinese researchers. Vents, or fissures in the sea floor, in general were first found to exist back in 1977 and have attracted attention since that time due to the unique life forms that call such areas home, and the fact that such vents tend to create tall mineral spires that look like chimneys which also quite often contain precious metals. It’s the existence of these metals though that could pose problems for the aquatic life as humans are apt to destroy the unique ecosystem in extracting them. The Dragon Vent, for example, is likely to be impacted soon as China has just recently been granted mineral exploration and extraction rights by the body of the United Nations responsible for doling out such permission.

Global warming threatens more than just coral Explore further Dutch designers from Waterstudio as part of the collab will construct a network of floating islands for luxury residences, hotels, convention center, yacht club and a floating golf course. For the number of 400,000 Maldives residents, a next-phase plan is to build islands for affordable housing. “Islands” are in the plural because the Maldives is an island nation in the Indian Ocean, made up of a chain of islands. These are 1,190 coral islands that are formed around 26 atolls, spread over 90,000 square kilometers. Sea level has risen since 1900. Scientists predict that the rising sea levels in the future, if ignored, could bring calamity and push the population out of their homes. The Maldives government, aware of the problem, first started thinking of alternative plans in 2008, when they began to take annual tourist revenue and place it in a fund to buy what may have been new homelands, possibly in Australia, India, or Sri Lanka. Now, however, they are turning to another solution in a partnership with the Dutch Docklands company. The floating islands that they envision will rise with the sea. Instead of fighting against the sea, they will coexist. The joint venture masterplan involves over 800 hectares/ 80 million sq.ft of water with floating developments. Dutch firm Waterstudio are project designers and Dutch Docklands are the floating architecture specialists engineering the project. (Phys.org) — From tourist paradise to devastation to sustainable future, an imaginative path toward rebirth is possible for global coastal populations at risk of being wiped out by rising sea levels. That path lies in artificial floating islands. The Maldives government is in a joint venture with the architectural firm Dutch Docklands International for the world’s largest artificial floating-island project. The present phase will focus on tourism. In turn super-rich globetrotters will enjoy the high end living activities they are accustomed to without having to fear being suddenly wrapped around a pole and dying. Citation: Maldives floating island masterplan tests the waters (2012, August 12) retrieved 18 August 2019 from https://phys.org/news/2012-08-maldives-island-masterplan.html The 18-hole golf course is one of the projects being given lots of international exposure, each with two to three holes, connected by underwater tunnels. The golf course is a $500 million project, paid for by the Maldives government and private investors. Forbes has referred to it as “the floating golf mecca.”Architects today are convinced that architects of the future will want to learn more about working with water instead of against it. In the past, engineers have used sand and rubble to create islands, but these structures disturb the sea and seafloor ecosystems. © 2012 Phys.org More information: www.dutchdocklands.com/maldivesvia PopSci, Dvice, io9 This document is subject to copyright.

Building-materials that the Dutch put to use include slabs of concrete and polystyrene foam. Their design concept involves foundations for buildings transformed into floats. They use a foam core encased in concrete, with steel cables securing it against the pull of potential currents. No matter how high the sea levels, the structures will remain above water. The foam core encased in concrete with steel cables all serve to prevent a structure from floating away.The Dutch company prides itself as using techniques that are environmentally friendly, or what they call “scarless” development. The design disturbs only a small patch of the seafloor, while preserving natural currents. Less space is disrupted on the sea floor with their design than if they were building with rock or sand. With sea levels rising all over the globe, scientists say it is possible that the Maldives venture could be a roadmap for future developing nations at risk. The success of this project is not yet proven but floating-architecture supporters believe it is a better concept to pursue than disbanding populations and sending them elsewhere.

The Olympic Games marks a once-in-four-years opportunity for providers of occasional use satellite capacity to make money and innovate. Anna Tobin reports on preparations for Rio.All over the world, occasional use (OU) satellite operators are getting ready for Brazil. The 2016 Olympic Games opens in Rio De Janeiro on August 5, and transmitting a growing, and increasingly tailored, set of sound and images out across the globe poses a huge logistical challenge to all those involved in the OU supply and delivery chain.Reaching around 3.6 billion viewers worldwide, the 2012 London Olympics was the most watched event in TV history, trumping most individual national broadcasters’ previous ratings records. With multiscreen viewing and interactive preferences still growing, the 2016 Summer Olympics are expected to outperform these figures. The 2014 Football World Cup in Brazil provided a good practice run for OU operators preparing for the Olympics, many of whom are using the same satellites, but they had only just packed up from this campaign before beginning the preparations for these Games.Eighteen months is the preparation time that Intelsat sets for major live events, according to Peter Ostapiuk, Intelsat’s head of media product services and management. “A major live event, such as the Rio Olympics, requires advanced and precise planning to ensure media customers have the reliable OU capacity they need to deliver exciting live content to viewers,” he says. “We work closely with customers to gather their requirements and then work internally with our capacity managers to identify capacity to successfully support media customers’ coverage plans.”The test period involves rigorous trailing of systems and solutions and assessing which infrastructures need to be expanded, according to Marc Logez, Globecast’s head of marketing, global contribution. “Modern events are, in many ways, as much about complex logistics as they are about technological solutions. Our customers’ demands can change right up to the last minute and we pride ourselves on finding innovative solutions to meet their needs – often quite late in the process. This is a core part of the value that we bring,” he says.In order to be able to offer such a rapid response service, OU operators need to be able to second-guess every possible request. They need to cope with mixed delivery to satellite and terrestrial networks and to be technically agnostic in the delivery of upstream and downstream services.There is no one-size-fits-all solution, says Intelast’s Ostapiuk. “Intelsat works closely with each individual customer to ensure customised bandwidth assignment for optimised efficiency and performance. We offer flexible short-term OU leases ranging from traditional short bookings for one hour, to leases for several weeks or a month,” he says. “Intelsat has also implemented ScheduALL Connector so customers can easily and efficiently secure OU capacity. During major sports events, such as the Olympics, customers need to be able to efficiently manage fluctuating bandwidth demands, while continuing to provide the high-quality, reliable content their viewers demand. The ScheduALL Connector interface allows media customers to easily view Intelsat’s available capacity, quickly match it to their needs and reserve it directly from within their own system.”It’s also important to remember that the Olympics is now so much more than ‘the Games’ itself. OU services [icitspot id=”565312″ template=”box-story”]will need to be in place in the long run up to the Games too, as the world’s media taps into any, even spuriously, related story. There will be food, travel and culture programming planned that will be filmed and transmitted from in and around Rio leading up to and during the Games. OU operators have to be ready to break stories from the city and its environs too. The Zika virus outbreak, for example, is already proving to be a major side story in this context.“It’s not just about the primary broadcasters and rights’ holders view of the world,” says Richard Lamb, senior director of OU operations at satellite operator SES. “From our experiences from such big global events, we have found that viewers and our customers have evolved from just looking at the Games themselves, to the more human stories around either the venue or the players. There is a lot more content emanating from the athletes arriving at the airport, the training grounds, etc. There is a lot more focus on the country itself; the Zika virus is a perfect example of how a story can become even more important, because of the Olympics.”It may not necessarily be the rights-holders looking to tell these stories. For news and entertainment broadcasters, this is where the immediacy of OU satellite technology comes into its own. “Satellite has a ubiquitous advantage of being able to switch on service almost immediately,” says Lamb.Advances since 2012Technology and consumers’ expectations of it have moved on, even in the few years since the London Olympics in 2012. There will be even more simultaneous feeds coming out of the Games, more multiple camera angles available and different replay and highlights options. All of this drives bandwidth needs.Consequently, more operators will be migrating from MPEG-4/H.264 compression to High Efficiency Video Coding (HEVC). “We’ve seen improvements in video encoding – MPEG2, MPEG4 – and we’re now looking at HEVC encoding, which is effectively the next generation. We expect to see an element of this in use at Rio,” says Lamb. “There are improvements in modulation as well, with new standards of DVB-S2x. All of these new techniques, ultra HD, HEVC encoding and higher order modulation will be a part of the Rio Olympics. There is a distinction, however, between what’s being captured locally, what’s being filmed and archived and what’s actually transmitted terrestrially by fibre and what’s transmitted by satellite.”How much of this actually gets transmitted live over satellite or fibre will be up to the broadcasters. Live content over IP will be another big development to watch for, says Logez at Globecast. “IP-based offerings are developing fast. Live-over-IP will be the next transition, but this will happen in a step-by-step evolution with a hybrid approach, because SDI is a mature technology that is available at a very reasonable price. Nevertheless, several issues still need to be addressed and solved, such as: type of connectivity at the venue, latency, security; and, recruiting new talent with IT specialised know-how,” he says.It’s not just the transmission technology that has moved forward in the last four years. The way people consume media has altered drastically too, with viewers wanting more content delivered to multiple devices. This has fed into increased demand for IP-based solutions. To thrive, satellite operators have to play a part in delivering this, says Ostapiuk at Intelast. “To meet customers’ needs as the media landscape rapidly changes, Intelsat is expanding its media services with IntelsatOne Prism, a multimedia networking platform and portfolio of managed services that allows customers to easily upgrade a legacy satellite-based network to a next-generation, automated hybrid satellite and terrestrial converged IP network. IntelsatOne Prism accommodates legacy and digital or multiscreen media and optimises network efficiency. It enables programmers to simplify operations with easy management of satellite and fibre capacity,” he says. “IntelsatOne Prism is ideal for the coverage of a special event like the Olympics, during which media customers benefit from automated-access voice, video and data links via two-way connectivity.”Added fibreWhile fibre’s bandwidth capability is impressive and it is playing a growing role in content transmission, it is unlikely to ever make satellite transmission redundant, because fixed networks can’t get to those hard-to-reach places that satellite can. Olympic competitions, such as open-water swimming, cycling and triathlons increasingly take place in remote areas of the host country and OU will always hold the fort here. Nevertheless, fibre is still eating into a chunk of the traditional OU business and many companies have decided that the only way to stop it eroding profits is to make fibre a big part of their own portfolios.“With regards to worldwide live broadcasting, satellite remains the most viable solution in the majority of cases,” says Logez at Globecast. “Satellite also offers a perfect backup for optical fibre links, especially in the case of highly sensitive video feeds. This is largely because of the lack of a single point of failure between satellite and fibre. Realistically, satellite and fibre cannot really be compared as their usage is very different. They are both part of Globecast’s core business, but also key factors in pushing beyond new frontiers – from a technological or geographical perspective.”Looking beyond the Olympics, industry participants expect OU to continue to play a primary role in transmitting live events, with a gradual move to more off-site production. “Remote production is now a tried and tested means of covering major live events, or those spread across multiple venues, allowing broadcasters to make cost and manpower savings by centralising the bulk of the production process,” says Logez at Globecast. Globecast’s managed service offering lets clients avoid complex logistics exercise, while the expansion of global IP networks lets the company explore new solutions for main and back up contribution solutions, he adds.Smaller businesses may also start utilising OU more in the future. In time for the Games, Intelsat launched its first high-throughput next-generation EpicNG satellite, Intelsat 29e, located at 310° East, at the end of January. This is designed to attract smaller businesses as it requires smaller terminals. “Intelsat 29e’s Ku-band spot capacity will be used to support contribution at the Summer Games, enabling customers to gather content from the venues and transport it back to their facilities,” says Ostapiuk. “Intelsat EpicNG delivers increased Megabits per Megahertz, providing customers the high performance they demand, as well as better economics, as they can simply access high-power Intelsat EpicNG capacity with smaller, solar-powered terminals.”Most of the developments in OU technology, especially the movement to IP, are driven by the demand for greater and greater interactivity, says Lamb at SES. “OU [providers] are gearing up to deliver more virtual reality content and more content for mobile devices. And more people watching the content on lots of different devices drives bandwidth [demand], and that bandwidth ultimately ends up on satellite. Even if it’s about mobile phone via WiFi or cellular technologies, ultimately you will see GSM back-hauling on satellites. There will be large amounts of data going via satellite to provide temporary increases in bandwidth. All of this has a positive effect on the business,” he says. For satellite, it looks like a win-win situation.
