What can you do at the scene! Rio Olympics look so cool!

1 Watch Olympics with VR: You're on the scene back to the top

[PConline Talk] This year is the Olympic year and there are less than five months. The 2016 Olympic Games will be held in Rio de Janeiro. This is also the first Olympic Games in South America. The charm of sports competition makes everybody ups and downs. At the same time, it also embodies the common awkwardness and hope of a country, a region and even a group. I remember that every time a Chinese player won the championship at the Olympics, our hormonal brethren as an audience was very active and excited, and we might have tears to run. This most primitive sports confrontation, the process of constantly challenging one's own limits, has aroused our blood and full of positive energy.

If you have the time and financial ability to watch the Olympics live and you can also buy a relatively good viewing position, it will certainly enable you to enjoy a more authentic Olympic grand occasion. But if you don't have time to go to Brazil and you want to stay at home, can you still enjoy the passion like the scene? Modern technology has given us some new possibilities. Broadcasting technology continues to be enriched and viewing equipment is constantly evolving. It is also getting closer to the world when they touch the world. Today Xiao Bian gave everyone a video relay technology that could be used in the Rio Olympic Games and the more realistic viewing equipment that we can enjoy at home.

Watch Olympics with VR: You are on the scene

The current VR technology can be described as a matter of course. Some media even pointed out that VR technology may replace TV in the future. This kind of conjecture may make people feel incredible. How can the development of television for decades be easily eliminated by such a thing? However, if the VR device is light enough and the picture quality is good enough, it may unknowingly occupy the home market. It is not impossible for the TV to eat gray on the side. Because VR can really bring a more truly outstanding viewing experience.

With regard to the theory of VR technology, Niang Huai has already had a lot of theories and this article will not explain it in detail. What will be the application of VR in sports events such as the Olympic Games? If you haven't experienced VR devices yet, it is recommended that you go to the store to experience Gear VR, HTC Vive, or Oculus Rift before you can expand your imagination.

Sports is a matter of enthusiasm. If you are wearing a VR device to watch the game, it is estimated that you can also move together. Messi's foot ball flies toward you, and you will definitely hide. This is the VR bring you a strong on-site interaction experience. If there are enough VR video equipments on the spot, you can look at the Olympics completely differently from others. You can even run to the court and pretend to be a referee, although no one on the scene can see you.

The development of VR in the sports field is by no means a fantasy. The representative solution manufacturer in this field is NextVR. As early as the 2015 All-Star Game, NextVR cooperated with Samsung, making the NBA the first mainstream sport to try VR live technology. alliance. Although the viewing angle was limited to 180 degrees, it still achieved the effect that other Guanyin equipment could not. In addition, Fox Sports has also cooperated with NextVR, live golf US Open, live NASCAR racing game.

At present, OBS has confirmed that it will use virtual reality technology to shoot at the Rio Olympic Games. By then, viewers in some areas can use compatible virtual reality head-mounted displays to immersively watch the exciting activities of the Olympic Games in Rio de Janeiro, including Opening ceremony, closing ceremony and daily key events. And these contents can also be downloaded as TV on-demand programs. As to whether there is any signal support in the country and the charging situation is still unknown.

Of course, the VR of the Olympic sports broadcast can not achieve the foolproof effect in terms of technical details. However, this active perspective allows the viewers to stay in sight of any place they want to stay. The audience can feel the atmosphere of the stadium and athletes more deeply. The state of the game is like visiting the stadium. You can also have more interaction if you can include the audience's atmosphere in VR live.

2 holographic projection to see the Olympics: you are on the court back to the top

Holographic projection to see the Olympics: you are in the stadium

I don’t know if you’ve ever seen the Microsoft HoloLens conference. Especially at the 2015 E3 game show, HoloLens’s stereoscopic 3D “My World” demonstrations were shocking to all the audience. Of course, HoloLens is not real. The holographic projection device is only virtual reality enhancement technology, but it is already so cool. Unlike VR devices, the real holographic projection is an image that appears in your existing space, as if it is floating in the air, changing the angle of view does not affect the sharpness, and the human body can penetrate the screen to walk past.

If such holographic projection technology is applied to the live broadcast of Olympic events, isn't it easier to go directly to the scene? You can even go along with Ronaldo in your living room and follow it to learn how to beat people. Of course, first of all you have to have a big house. According to the current Tianhe house price of 29,496 yuan/m2, if you want to have 1/10 football field-sized houses, you have to prepare 20 million. If you want to have a whole football field-sized house...it's no kidding. When you think Sicong Young really bought a house to watch the Olympic hologram practice skills, I'm going to fire. That's not good.

Holographic projection of a game is equivalent to cloning to another stadium for people to enjoy the game, you can feel the athlete's speed, height and technical gap in real time. However, it is impossible for ordinary families to have a 1:1 size place to enjoy a game, so a reduced version of the holographic projection would be useful. It is reported that Japanese telecom operator NTT is developing this new communication technology and plans to apply it to sports broadcasts and name this technology "Kirari". At present, the Kirari tester has been able to launch a reduced version of the table tennis game image, the effect is also very good.

Of course, a better method is to use holographic projections to show in stadiums or theaters and share the grand occasion of the stadium.

8K clarity broadcast, complete

What is the concept of 8K resolution television? 7680×4320 is 4 times that of 4K TV and 16 times that of 1080P. At the same time, 8K not only brings improved resolution, but also has corresponding improvements in brightness, dynamics, color gamut, and color depth. What would it be like to watch the Olympic Games live on such a viewing device? As if everything is in front of your eyes, even if you come close, you still can't see any pixels on the panel. This is an ultimate immersive experience.

Recently, the foreign media said that the OBS has confirmed that the 2016 Brazil Olympic Games will also adopt 8K resolution and 22 surround sound technologies. The broadcast content will include opening and closing ceremonies, swimming, basketball, football, and gymnastics. Take about 130 hours of 8K video content, but these videos will be exclusively for 8K TV users in Japan. This has also become a test of Japan's 8K resolution solution, because after another four years, the Olympic Games will be in Tokyo. At that time, it is estimated that the real 8K Olympic Games broadcast will be fully rolled out in Japan.

Compared with VR and holographic projection technology, 8K broadcast technology is also very difficult, shooting equipment and playback equipment already have 8K products, but the transmission capacity has become a very deep, especially in the country, think of home 4m Small water pipe, really burst into tears. Before the new round of transmission revolution and video coding revolution came out, 8K and even 4K live broadcasts may only be small-scale pilots. But OBS also said that they also converted captured images from 8K ultra high-definition to 4K signals and hoped that it could also experiment with high-resolution transmission and a wider range of color gamut and high dynamic range technologies. If your home broadband is not enough, or there is no 8K TV, you can also watch live broadcasts of the Olympics through 4K Ultra HD broadcast. 8K is already feasible in Japan, 4K is still unknown in the celestial era.

3HDR TV: The Economy is Really Back to the Top

HDR TV: The economy is real

In the past, although the high-end atmosphere has been effective in several ways, it has been limited by the status quo of domestic broadband and the economic power of ordinary families. Most of them are only local tyrants. However, there is also a very popular display technology this year that allows you to enjoy the viewing experience you have never had before at a relatively low cost. This year, TV manufacturers have laughed at the HDR technology.


Comparison of SDR (Left) and HDR (Right) Effects

With regard to the theory of HDR, I don't think I need to worry too much about the effect. This technique of increasing the dynamic range of the brightness expresses many details that you have never seen before on television. Give a simple example. The opening ceremony of the Olympics must be on the night of Rio. In reality, the sky and venues of Rio Night will be colorful. Especially when the Olympic flame is ignited, it must be particularly magnificent when it burns, and those who may not have been There may be a lot of moving details about where the light fireworks shine. These scenes are shown on ordinary television. The contrast and latitude of the paintings must not be perfect. Some of the highlights of the fireworks may be overexposed, so that you can't see the original colors of the fireworks. The crowd on the audience seats may be dark. Can't see the movement of people dancing.

But if you shoot with HDR-enabled video equipment and then play it on HDR TV, the picture you pass to your eyes will be exactly the same as the scene. The specific reason you must have seen a lot of analysis articles, summed up as a point is that if the brightness of the human eye can be observed as a range of 10 (brightest to the details of the fireworks highlights, the darkest to the crowd in the shadow of the dance moves), Normal video and TV can only express the brightness range of 6, while HDR TV can display the brightness dynamic range of 10 in all.

Especially when you are looking at rhythmic gymnastics or synchronized swimming, how can the girls be able to miss the true side of the most graceful movements and sweet and warm smiles? Can you tolerate the rich or poor television color performance? In order to get the most realistic results, HDR video and viewing equipment are required to perform.

At present, major TV manufacturers have basically supported the HDR function for 16 years. Most of Sony's, Samsung's, LG's, TCL's, Skyworth's, and Hisense's have a complete HDR ecosystem. In the front-end shooting equipment, the Rio Olympic Games will certainly use the HDR recorder, because HDR in the camera field has also been played by Sony for several years. HDR can break the bottleneck of the color space, which is also an important direction for the development of video technology and display technology in the future.

Conclusion: The Olympic Games every four years is not only a grand event for sports, but also a scientific and technological contest. Whether it is technology equipment around the scientific training of athletes or scientific and technological means to improve athletes’ athleticism, or the image acquisition technology, image transmission technology and display technology that spread the flourishing world to all parts of the world, they are constantly evolving with the Olympic Games once every four years. . The several black technologies introduced in this article are not far away from us, and most of them have already become system prototypes. In the not-too-distant future, there may be even more real-life experiences, like the fact that we are at the Olympics site and we are in full swing with the rhythm of the competition.
