VR so many areas of the whale whine Why do you take a look at the VR live?

Text / VR dimension Sun Sun

In February 2014, Facebook spent US$2 billion to acquire Oculus, a VR startup company. This sparked the attention of the outside world to VR. It also drove the layout of a large number of domestic companies in the field of VR. Chinese culture and its micro whale are among them. .

On August 8th, Microwhal VR’s parent company Chinese Culture (CMC) announced that B’s share of the US VR live broadcast company NextVR was the third time that Chinese culture and microwhal VR had launched major capital actions in VR field in the past three months. : On May 31st, Microwhale and Shanghai Media Group (SMG) and JAUNT jointly established JAUNT China, with a total investment of more than 100 million U.S. dollars. On April 25, the micro-whale announced that it will invest 1 billion yuan in innovation industry funds worldwide. , Teammates produce 10,000 hours of VR content.

In just a few months, Chinese culture and micro-whales frequently shot in the field of VR and entered the VR core entertainment category such as sports, music, and film and television in the content field. Content partners include international giants such as Comcast, Disney, NBA, and Fox.

The VR exclusive interview with Li Weiyu, the CEO of the Little Whale, combs the strategic layout of the microwhales in the VR field, interprets the opportunities or challenges faced by the microwhales in the VR field, and also provides lessons for domestic companies to enter VR.

VR layout preferred VR live

From the VR strategy conference in April to the present, Chinese culture and micro-whales have multiple layouts in the VR field. The VR dimension has sorted out this:

From the table, we can see that the layout of VR for the micro-whales is mainly selected from the “live” path, including the live broadcast of a variety of variety shows and sporting events. Xiao Wei CEO Li Huaiyu said to the VR dimension that the microwhale chose to deepen VR in the live broadcast field, mainly based on two considerations:

There is a market: the sense of presence and immersion brought about by VR is in line with the actual needs of many sports and art lovers.

Ability: In the current VR technology, live technology relative to VR games and other technologies are relatively more advanced and will do better in VR experience.

From the perspective of market size, the Goldman Sachs exclusive VR report released by the VR dimension shows that by 2025, the VR live broadcast market space will reach 2.5 billion U.S. dollars; from the perspective of user acceptance, a new study shows that consumers are most interested in The top three VR content is travel (74% support rate), movie (67% support rate) and live broadcast (67% support rate), which can be seen VR live in the user's mind.

Li Huaiyu further explained the two major advantages of micro-whales in the field of VR broadcast:

At the resource level, micro-whales can take advantage of the content IP of Chinese culture and have many partners.

On the technical level, the microwhale live broadcast team has strong research and development capabilities. For example, the use of self-developed octahedral code can reduce half of the bandwidth usage without reducing the definition, which reduces the cost and improves the fluency. Sex.

The theme of VR broadcast covers a wide range of topics. NextVR has used VR technology live concerts, NBA and rugby games. Rio Olympics and Pingchang Winter Olympic Games will also use VR live broadcast, broadcast, and some companies even use VR technology to broadcast live. U.S. Presidential Election Debate. But among many topics, which are more suitable for live broadcasting using VR technology?

Li Huaiyu said frankly that the micro whale has made VR live on national football, boxing, fighting, figure skating and concerts, and VR+ concerts and VR+ sports have all been tried. Relatively speaking, most VR live broadcasts with relatively small venues and relatively static projects are suitable for screen capture and have lower technical difficulty. The current user experience will be better.

VR live broadcast bottlenecks need to be cracked

At present, there are still many problems faced by VR live broadcasting. The issues of clarity, interactivity, bandwidth and speed, and delay are all important factors that restrict its development.

Scott Stein, a reporter of the foreign technology website CNET, was wearing a VR headset to watch a Democratic debate on CNN's live broadcast and recorded his real experience. The VR dimension was summarized:

1. The VR helmet pulled the audience into the studio, but it did not feel the real atmosphere of the scene. After entering the VR world, I could not concentrate on listening to the content of the debate. I did not know how the people around me reacted to the debate. There was no sense of existence.

2, VR live broadcast the biggest advantage is the powerful "on the spot", but for this "on the spot", it also made a lot of sacrifices, the video is not good enough in sharpness, focus and purity, video quality and live TV In contrast, there is a certain gap.

3, the characteristics of panoramic video allows viewers to truly see the activities of people around themselves, but this feature also brings a problem - lack of energy.

4. When users watch live broadcasts, they often need to interact with people in the vicinity, but in the VR broadcast, all this will not happen.

From these issues, to solve the VR live broadcast slot, you need to make multiple improvements from the live camera, the transmit end, and the watch end, and look further, in order to get rid of the user's "boring feeling" when watching VR live, future VR Live Streaming should embed more input devices and interactive elements, such as turning the handle into hands in the virtual world, and touching certain objects in the VR live view.

The micro whale proposed the following solutions for the current VR broadcast pain points:

In terms of video quality, octahedron algorithm optimization is used to provide a clearer viewing experience under existing bandwidth conditions.

In terms of interactivity, as the interaction of the software developed by the micro-whales and the implantation of the social attribute content, the audience experience in addition to live viewing in the virtual world will have a richer experience.

In addition, VR live broadcast has a big elbow: the cost is too high. There have been media reports that the cost of VR live streaming is mainly the cost of the transmitting end. It is common labor cost to take pictures now. Post production assumes that the highest 10 minutes of VR content will be sent to the cloud, and the live broadcast cost is about 10,000 yuan.

In this regard, Li Huaiyu said that the cost of bandwidth comes from two aspects: First, the on-site signal upload to the server requires the application of the operator line, a single live broadcast cost range of about 10,000 to 50,000, and the specific program duration, the number of users, etc. has nothing to do with One is the CDN export bandwidth cost, which is the direct bandwidth cost from the server to the viewing user. If a better VR viewing experience is guaranteed, the bandwidth requirement of a single user will be about 10 times that of traditional video, but based on the current user base. It has not reached an unacceptable level, but the future must be the bulk of the cost.

To solve this problem, we must mention NextVR that is aligned with the micro-whale. In September 2014, NextVR independently developed a set of Red Dragon camera system worth US$180,000. It uses six Red Epic Dragon (commonly known as Red Dragon) 6K cameras to capture three-dimensional 360-degree video. The feature of this system is that it can utilize the proprietary streaming media solution to allow users to watch this resolution video through the general home and mobile internet.

The combination with Next VR may help the micro-whale solve this barrier. Li Huaiyu said that the use of NextVR's algorithm enables the microwhales to enable users to watch VR videos smoothly with low bandwidth, help reduce live broadcast costs, and accelerate the promotion of VR live broadcasts.

In addition to live streaming, these areas should also try

The increasing popularity of VR technology, while still pulling a new video market - 360-degree panoramic video.

Although 360-degree panoramic video cannot be called true VR technology, it has become the only way for most users to go into VR era. YouTube, Facebook, Samsung, etc. have all launched 360-degree panoramic video platforms. Domestic companies are also “ready to make moves” and micro-whales have naturally invested a great deal of energy into them. From the above table, we can see that the micro whale recorded the VR version of Li Yuchun's new song MV and took a VR sitcom.

However, there is a certain chaos in the industry. As mentioned above, panoramic video is not a real VR technology. However, most domestic video companies are using VR video tags to launch panoramic video.

A developer working on 360-degree panoramic video in the PC era said that for people who study VR, they may be a little annoyed at 360-degree panoramic video, and many people who have experienced 360-degree panoramic video see it as VR technology, but in fact it is not.

The difference between VR video and panoramic video (VR sorting)

Li Huaiyu also holds the same view: The VR industry is still in its infancy, and the user acceptance is still at a relatively elementary stage. Therefore, some enterprises need to be able to lead the user’s perception through real VR video and give users Good experience.

With the increasing popularity of VR video, it will have to mention an upgraded version of VR video - VR movies. According to the market research agency Digital-Captial's forecast, the revenue of the entire VR market will reach 30 billion U.S. dollars by 2020. The VR movie will contribute only a sub-game and hardware equipment to the revenue. Therefore, VR movies are also areas for micro-whales to open up. .

Previously, Microwhale, Shanghai Media Group (SMG) and JAUNT announced the establishment of "JAUNT China," which replicates all of JAUNT's operations in the United States, focusing mainly on the VR film and television industry.

According to Li Huaiyu’s description, the microwhales will focus on the ecological layout of VR film and television in the future, from the front-end shooting to the back-end viewing experience equipment, and the VR content production and platform construction will be formed around these two ends.

summary:

By sorting out the layout of the micro whale VR, we can see that the micro whale has a very clear VR strategic positioning: the production of VR content including live broadcast, film and television, and the establishment of a content platform, after all, "backs" the Chinese culture of this mountain The micro whale has natural advantages in copyright, IP, shooting team, capital chain, etc. Although there are layouts of VR hardware, it is not the core strategy of the micro whale. This may be a domestic company with poor hardware capabilities. Good use for reference.
