With the advancement of VR hardware technology in companies such as Facebook and Sony, VR technology has gradually moved from behind the scenes to the stage, and the combination of VR and video has become the next epidemic in the field of video broadcasting. According to the latest research report of Goldman Sachs, the number of VR live broadcast users in 2020 will reach 28 million, and the market revenue will be 750 million US dollars.
At present, the mainstream live broadcast platforms at home and abroad are actively deploying VR live broadcasts. For example, Twitch, the US game-playing giant, has announced the launch of the VR live broadcast platform, and the domestic mobile live broadcast platform, pepper live broadcast, has also launched its own VR mobile video live broadcast. What are the reasons for the tech giants to enter the VR live broadcasting? Is VR live broadcasting a real or virtual fire?
What is the reason for VR live broadcast?
Reason 1: Give the user visual enjoyment
The VR broadcast breaks the boundaries of the screen space and distance of the mobile phone, and prompts the user to change from the onlookers to the participants, which narrows the distance with the user and broadens the audience. Users can broadcast live through VR to achieve a distance through time and space, and close contact with popular stars and the scene.
For example, not long ago, Liu Yan played live with pepper and played with the pepper staff to find the “Men God†game, which attracted the attention of netizens. The live broadcast began 30 minutes later, the number of followers of the fans exceeded 4 million, and a total of 6 million people simultaneously interacted on-line during the two-hour live broadcast. Various gifts were constantly being screened. It is said that during the live broadcast, both the PC and the mobile end simultaneously. The number of people online adds up to nearly 20 million.
Reason 2: Live Broadcast Expands VR Application Scenarios
Many domestic and foreign innovators in various industries have seen the application prospects of VR live broadcasting. VR live broadcasting has begun to be applied in more and more industries. It is not just the medical industry that hopes to use it for live VR operations. The education industry can do classroom VR interactive teaching. Even the Rio Olympic Games will use VR to broadcast the Olympic Games.
According to recent news, NBC teamed up with the Samsung VR Live Rio Olympics. As long as Samsung's VR headset is worn, users can obtain 85 hours of VR video content through NBC Sports (National Broadcasting Corporation Sports Channel) app. The video will provide opening and closing ceremonies as well as exciting highlights of various events, including men's basketball, gymnastics, track and field events, beach volleyball, diving, boxing and fencing. The VR video for the production of these competitions is the Olympic Broadcasting Service Company. The company is affiliated with the International Olympic Committee and has been responsible for providing video recordings of the Olympic Games to broadcasters from various countries.
Reason 3: Bring more convenience to people's lives
At present, whether it is the premiere of a popular movie or a concert, if it is delayed due to other things, it will not be able to participate in a timely manner, and VR Live will make up for the regret that we cannot go to the scene to watch, allowing users to be immersed in the utmost. As long as the user wears a virtual reality helmet, he can watch what he wants at any time.
It is undeniable that the immersive feeling brought by VR live broadcasting will indeed subvert the way people experience. However, from the perspective of future developments, VR live broadcasting cannot replace traditional media transmission methods such as computers and television.
As a popular VR live broadcast platform, there are actually many immaturity factors, such as lack of innovative content, large production cost, large market size, inadequate technology, and broadband issues, which hinder many issues. The development of the industry.
The outlook is worrying, many problems are solved
Issue 1: Lack of innovative content
Although the VR live streaming of entertainment stars and net red has brought certain benefits to users, the lack of innovative content will cause users to lose the same type of live content every day when users spend the fresh period. Interest, resulting in the continuous loss of users of VR live platform. If you want to retain users, VR broadcast platform needs continuous innovation to attract users to stay longer and increase sticky users.
Question 2: The production cost is big
From the business model point of view, the cost is costly, a period of 4 minutes of VR video costs at least 600,000, if the video site wants to profit through VR video, the indoor scene needs to be ready, the rent of an indoor room alone will make this The VR broadcast becomes very expensive; at the same time, since the amount of users watching the VR broadcast is relatively small and the device needs to be watched, the user's stickiness is greatly reduced from this point of view.
Question 3: The market is narrow and it is difficult to achieve a leap from niche to the public
At present, everyone has low awareness of VR. If users want to experience VR live streaming, they must purchase or wear virtual reality helmets to experience the immersiveness of the anchor's presentation content. However, the current hardware market technology is not yet mature. From the perspective of high prices, it is still very serious and difficult for consumers to become popular.
Question 4: Technology is not mature enough
As long as the user wears a VR device for a little longer, it will feel dizzy. After all, there are still some deficiencies in the technical aspects of VR live broadcasting. Look at it from the following aspects:
1, the lack of sound
Realistic VR live broadcasting requires the cooperation of panoramic sound. At present, some live broadcast sounds are mainly obtained through the mixing console, but such an impromptu feeling is poor. Because the recognition of sound by human beings is not flat, but is of multiple dimensions, the difference between up and down, left, right, up, and down, affects the user's experience. Therefore, VR live broadcasting requires 3D sound to enhance the presence.
2, the splicing algorithm is difficult
VR video production is currently relying on a number of wide-angle lens acquisition, splicing through algorithms into a complete panoramic video. However, with the current technology, there is no manual stitching of the panoramic camera, and it is difficult to achieve a "seamless" effect. The level of the artificial stitching algorithm decides the overlapping effect of the stitched images in the wide-angle overlapping area. If the splicing is not good, serious vertigo may result.
3, VR live shooting mode is very simple and lack of interactivity
At present, VR live broadcasts use head-end devices and mobile-end application modes. The user's perspective is mostly fixed. Many manufacturers directly put a panoramic video inside, and some of the cameras may allow users to have a panoramic video. The sensation of being on the spot, but some of them are dry and dry, and it does not give the user a very interactive experience. The shooting techniques and shooting methods are very simple. They lack the interactivity. The mobile broadcast is attractive because of the above It can interact with content in real time, but VR Live does not implement this technology. If VR live streaming cannot achieve strong interaction with content, the resulting problem is that it cannot bring users a good sense of immersion. So, relatively speaking, this is also an important reason to hinder the popularity of VR live broadcasting.
For example: Scott Stein, a reporter of CNET, a foreign technology website, watched a Democratic debate on CNN's live broadcast with a VR headset and recorded his real experience. He said that under the existing VR technology, when watching live broadcasts, you completely It's a ghost floating in the air, what the camera sees, and what you can see, but the surrounding audience can't communicate with you at all. Then you feel lonely. As long as you wear a headset, you are thrown into an island and you can't do anything but watch the debate.
Question 5: The limited level of broadband affects the quality of the picture and the number of online users
In theory, VR Live can support countless people watching online at the same time. However, in reality, VR broadcast currently supports up to 10,000 people online at the same time. From this point of view, the current broadband level is still difficult to meet the needs of users. In addition, how to ensure that the network quality is not good, can be unique through The network protocol maintains relatively high-speed and stable transmission. In the weak adaptive acquisition, when the network environment is weak, how to use the automatic adjustment of the resolution to reduce the occurrence of the Caton phenomenon, etc. These are problems that the VR broadcast must overcome.
According to the current development status of the VR live broadcast market, there is no shortage of manufacturers providing VR equipment for the entire industry. There are also many equipment companies that watch VR equipment. However, for the VR live broadcast platform, what is really needed is a manufacturer that can provide all the hardware devices from shooting to viewing, and software integration capabilities.
It seems that it is not that easy for VR to live on fire.
