企業級直播帶貨時代來臨:VR/AR視頻直播在全球發布會中創造無限可能
VR虛擬直播、AR視頻直播
拓源新思視覺技術團隊,為您在全球范圍內打造各種超現實的線上發布會,并將流量分發至各視頻平臺,讓帶貨發布直接改變未來營銷趨勢。
因為疫情的傳播,導致很多企業計劃內的發布會,不得不取消。
最近幾個在行業有超前影響力的發布會,給我們帶來了全新的視野。
一個是:小米的手機發布會,雷軍通過一場現場無人參加的在線直播做了一個首開先河的發布會,跟時間做了一次賽跑。
接下來,更酷的是三星手機發布會,直接用自帶的軟件,進行了AR直播。成熟的摳像技術配合虛擬3D場景,讓你仿佛置若現場。
關鍵的是,成本超低到你想像。
與其在沒有人的現場搭建舞臺花費,不如拿這個錢去買流量---這個,顯然比雷軍更勝一籌。
進行直播,為了能達到更好的視覺效果,往往要借助VR或AR直播技術。
VR是指360全景直播,利用360全景攝像設備,將你置身舞臺現場,配上專用的VR眼鏡,就可以有身臨其境的感覺了。
而AR是指增強現實技術,讓虛擬的場景與真實的人物揉合到一塊,并通過實時渲染設備,就打造了一個沒有真實舞臺的“真實”場景了。
關于AR設備的詳細描述:Vizrt AR做為全球領先的AR增強現實系統,適用范圍廣、應用領域多、可靠性高,可以為綜藝、體育賽事節目提供炫酷的AR包裝。如CCTV、FOX、BBC、SKY、ESPN等全球知名電視臺,均采用Vizrt的AR和在線包裝系統,尤其在電競領域,拳頭和暴雪兩家公司所有的電競賽事,在線包裝和虛擬AR均使用Vizrt系統。國內騰訊的英雄聯盟、王者榮耀的大型賽事所有炫目耀眼的AR效果,都是通過Vizrt系統實現的。
Detailed description of AR equipment: Vizrt AR, as the world's leading ar Augmented reality system, has a wide range of applications, many fields of application, and high reliability. It can provide cool ar packaging for variety shows and sports events. For example, CCTV, fox, BBC, sky, ESPN and other world-famous TV stations all adopt Vizrt's AR and online packaging system, especially in the field of e-sports, Vizrt system is used in all E-sports events of fist and Blizzard companies, online packaging and virtual ar. All dazzling ar effects of China Tencent's hero League and King's glory large-scale events are achieved through Vizrt system.

拓源視覺科技擁有大型AR現場項目案例,在充分吸收AR技術的同時,我們還結合國內國情提供全面的現場執行方案和項目設計方案。
提起VR直播,很多人都不會忘記去年科比職業生涯最后一場NBA比賽。NextVR利用VR直播技術,讓不能親臨現場的球迷也能感受到比賽中海嘯般的歡呼吶喊聲,身臨其境的感受比賽上的激烈,見證科比退役的那一瞬間。如今,NextVR開放了VR直播觀看資格,所有用戶都能付費觀看每一場NBA全明星比賽。
隨著技術的發展,VR也在由科技概念變成商業現實。VR直播是虛擬現實與直播的結合,VR直播是怎么實現的呢?簡而言之,其從拍攝到觀看的全流程可以概括為:全景相機+拼接合成服務器+編碼上傳+點播機房分發+用戶收看。具體來說,全景相機采集視頻數據后通過電腦或者工作站進行實時拼接,再經過編碼推到機房進行分發,最后是用戶通過VR頭盔+手機/電腦進行觀看。在這個流程中,除了全景相機和拼接環節,VR直播與傳統直播并沒有太多區別。
VR直播對設備的要求較高,從流程、拍攝端,傳輸到云端分發,到播放端,頭盔,端到端,還有視頻的應對,幾乎每一個環節都要求甚高。VR直播需要采用360度全景的拍攝設備,不僅要有多顆廣角鏡頭,還要傳感器同步、色彩及白平衡參數一致,以捕捉超清晰、多角度的畫面,每一幀畫面都是一個360度的全景,普通的手機攝像頭和PC攝像頭難以滿足拍攝要求。
隨著科技的發展,VR直播所需的設備也在逐漸發展,VR攝像機已經有商業技術解決方案,像得圖F4和諾基亞OZO等都可以進行VR直播。諾基亞OZO價格大約4.5萬美元,對于一般人而言有些昂貴,但是對于電視臺、影視制作公司等專業平臺來說并不算太貴。也就是說,在VR攝像機上已經不存在難題,難就難在VR直播最核心的畫質和實時拼接問題。
走在VR直播最前沿的是美國的NextVR,其有拍攝、壓縮、傳輸和VR內容顯示等26項專利做技術支撐。除了擁有數據壓縮技術,NextVR還擁有一款專門用于實時轉播360度VR節目的全景直播卡車,這兩項技術在時 間和空間上就保證了內容的實時性和可看性。對于VR直播來說,技術才是保障它帶給用戶畫面即時、畫質清晰、內容精彩的必要因素,NextVR技術上的領先直接拉開了它和其他競爭對手的差異。
At the forefront of VR live broadcast is nextvr in the United States, which is supported by 26 patents such as shooting, compression, transmission and VR content display. In addition to the data compression technology, nextvr also has a panoramic live truck dedicated to the real-time broadcast of 360 degree VR programs. These two technologies ensure the real-time and visibility of content in time and space. For VR live broadcast, technology is the necessary factor to ensure that it brings users instant pictures, clear picture quality and wonderful content. Nextvr's leading technology directly opens the difference between it and other competitors.
由于對畫質的極高要求,VR直播比傳統的普通直播的技術參數高出近一倍,最少要2560*1440(2K)分辨率/30M碼率/90幀幀率。而且,現有條件下,使用PC客戶端+VR頭顯才能提供最好的臨場沉浸體驗、最逼真的3D視角效果。另外,用戶想要觀看親臨現場般的VR直播,用戶使用的網絡帶寬必須大于VR視頻的碼率,如果是2K分辨率,用戶實際的下行帶寬至少大于30M。
Due to the high demand for image quality, VR live broadcast has nearly twice the technical parameters of traditional ordinary live broadcast, requiring at least 2560 * 1440 (2k) resolution / 30m code rate / 90 frame rate. In addition, under the existing conditions, PC client + VR head display can provide the best immersive experience and the most realistic 3D perspective effect. In addition, if the user wants to watch the live VR video, the network bandwidth used by the user must be greater than the code rate of VR video. If the resolution is 2K, the actual downlink bandwidth of the user is at least greater than 30m.
雖然國內許多直播平臺都相繼開設了VR直播頻道和VR直播間,還有許多明星的演唱會推出VR直播,但是因技術條件等因素限制,氛圍感受卻達不到相應的效果,用戶體驗不佳。由于現階段技術上存在的不足,導致國內VR直播提供不了畫質清晰、流暢度好、結構完整的內容,這也是用戶詬病的重要原因。
另外,目前國內涉足VR直播的都是一些直播平臺,各個平臺沒有為VR直播做好技術儲備,分辨率、刷新率和碼率都不夠,而且大部分用戶使用的手機觀看VR直播,而不是VR頭顯,由于手機本身的低分辨率、低刷新率限制,使用手機VR盒子時間稍長就會出現眩暈感,而且手機長時間渲染VR視頻,往往會導致嚴重的發熱問題。因此,短時間內國內VR直播不能達到最低標準,也無法滿足用戶的需求。
In addition, at present, the domestic VR live broadcasting platforms are all live broadcasting platforms. Each platform has not made technical reserves for VR live broadcasting, and the resolution, refresh rate and code rate are not enough. Moreover, most users use mobile phones to watch VR live broadcasting, rather than VR head display. Due to the low resolution and refresh rate of mobile phones, the use of mobile VR boxes will cause vertigo for a little longer time. Moreover, the Rendering VR video on mobile phone for a long time often leads to serious heating problems. Therefore, in a short period of time, domestic VR live broadcast can not meet the minimum standards, nor meet the needs of users.
所以,國內做VR直播的平臺應該把重心都放在如何提高技術和優化內容上面,增加自身的實力才有競爭的資本。內容和技術兩者是相輔相成,好的內容需要提供技術支撐,好的技術需要優質內容來填滿,NextVR為什么有資本傲視VR直播領域,這就是它成功的因素。
Therefore, domestic platforms for VR live broadcasting should focus on how to improve technology and optimize content, and increase their own strength to have competitive capital. Content and technology complement each other. Good content needs to provide technical support, and good technology needs to be filled with high-quality content. Why nextvr has the capital to be superior to VR live broadcasting field is its success factor.
With the development of VR industry, more and more manufacturers will develop VR products in the future, and China's VR live broadcasting market will become larger and larger. At last, the VR live broadcasting of all platforms can reach the market level, only taking time, not now.
隨著VR行業的發展,未來會有更多的廠商開發VR產品,我國的VR直播市場也會越來越大,最后各平臺的VR直播都能達到市場水平,只是需要時間,而不是現在。
