企業(yè)級直播帶貨時代來臨:VR/AR視頻直播在全球發(fā)布會中創(chuàng)造無限可能
VR虛擬直播、AR視頻直播
拓源新思視覺技術(shù)團隊,為您在全球范圍內(nèi)打造各種超現(xiàn)實的線上發(fā)布會,并將流量分發(fā)至各視頻平臺,讓帶貨發(fā)布直接改變未來營銷趨勢。
因為疫情的傳播,導(dǎo)致很多企業(yè)計劃內(nèi)的發(fā)布會,不得不取消。
最近幾個在行業(yè)有超前影響力的發(fā)布會,給我們帶來了全新的視野。
一個是:小米的手機發(fā)布會,雷軍通過一場現(xiàn)場無人參加的在線直播做了一個首開先河的發(fā)布會,跟時間做了一次賽跑。
接下來,更酷的是三星手機發(fā)布會,直接用自帶的軟件,進行了AR直播。成熟的摳像技術(shù)配合虛擬3D場景,讓你仿佛置若現(xiàn)場。
關(guān)鍵的是,成本超低到你想像。
與其在沒有人的現(xiàn)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(shù)。
VR是指360全景直播,利用360全景攝像設(shè)備,將你置身舞臺現(xiàn)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(xiàn)實技術(shù),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(shè)備,就打造了一個沒有真實舞臺的“真實”場景了。
關(guān)于AR設(shè)備的詳細描述:Vizrt AR做為全球領(lǐng)先的AR增強現(xiàn)實系統(tǒng),適用范圍廣、應(yīng)用領(lǐng)域多、可靠性高,可以為綜藝、體育賽事節(jié)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(tǒng),尤其在電競領(lǐng)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(tǒng)。國內(nèi)騰訊的英雄聯(lián)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(tǒng)實現(xiàn)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.
拓源視覺科技引入戰(zhàn)略投資購買多套Vizrt維斯系統(tǒng),兼容主流電競賽事的在線包裝和AR創(chuàng)意,同時還購置了挪威Stype搖臂跟蹤系統(tǒng),日本SHIOTOKU跟蹤云臺、Mo-sys紅外跟蹤系統(tǒng),并自主研發(fā)室內(nèi)GPS飛梭攝像機跟蹤系統(tǒng)。
TOWIN vision technology introduced strategic investment to purchase multiple sets of Vizrt Weiss system, which is compatible with online packaging and AR creativity of mainstream E-sports events. In addition, it also purchased Norwegian type rocker tracking system, Japanese shiotoku tracking platform, Mo sys infrared tracking system, and independently developed indoor GPS flying shuttle camera tracking system.
這套綜合系統(tǒng)是市面上性能最穩(wěn)定、效果最佳的虛擬現(xiàn)實(AR)實用方案之一,已經(jīng)成為CNN、BBC、福克斯體育頻道等國外媒體的標(biāo)配。國內(nèi)江蘇衛(wèi)視、湖南衛(wèi)視和騰訊視頻等大型媒體機構(gòu)均采用相同技術(shù)。
虛擬演播廳、影視棚 演播廳出租,實時摳像 1080P畫質(zhì)更真實。
星眾直播建造廣播級大、小影視虛擬演播室出租,有高清、標(biāo)清攝像機及后期剪輯、切換設(shè)備,提供專業(yè)操作員,演播室出租。
可拍攝主持人串場,主持人摳像、小型訪談、采訪、教學(xué)、培訓(xùn)課程、講座、商品展示等。
This integrated system is one of the most stable and effective virtual reality (AR) practical solutions on the market, and has become the standard configuration of CNN, BBC, Fox Sports Channel and other foreign media. Jiangsu Satellite TV, Hunan Satellite TV and Tencent video all adopt the same technology.
Virtual studio and film studio studio studio rental, real-time matting 1080p image quality is more real.
拓源視覺科技擁有大型AR現(xiàn)場項目案例,在充分吸收AR技術(shù)的同時,我們還結(jié)合國內(nèi)國情提供全面的現(xiàn)場執(zhí)行方案和項目設(shè)計方案。
提起VR直播,很多人都不會忘記去年科比職業(yè)生涯最后一場NBA比賽。NextVR利用VR直播技術(shù),讓不能親臨現(xiàn)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(shù)的發(fā)展,VR也在由科技概念變成商業(yè)現(xiàn)實。VR直播是虛擬現(xiàn)實與直播的結(jié)合,VR直播是怎么實現(xiàn)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(wù)器+編碼上傳+點播機房分發(fā)+用戶收看。具體來說,全景相機采集視頻數(shù)據(jù)后通過電腦或者工作站進行實時拼接,再經(jīng)過編碼推到機房進行分發(fā),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(huán)節(jié),VR直播與傳統(tǒng)直播并沒有太多區(qū)別。
VR直播對設(shè)備的要求較高,從流程、拍攝端,傳輸?shù)皆贫朔职l(fā),到播放端,頭盔,端到端,還有視頻的應(yīng)對,幾乎每一個環(huán)節(jié)都要求甚高。VR直播需要采用360度全景的拍攝設(shè)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(shù)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(fā)展,VR直播所需的設(shè)備也在逐漸發(fā)展,VR攝像機已經(jīng)有商業(yè)技術(shù)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(yè)平臺來說并不算太貴。也就是說,在VR攝像機上已經(jīng)不存在難題,難就難在VR直播最核心的畫質(zhì)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(nèi)容顯示等26項專利做技術(shù)支撐。除了擁有數(shù)據(jù)壓縮技術(shù),NextVR還擁有一款專門用于實時轉(zhuǎn)播360度VR節(jié)目的全景直播卡車,這兩項技術(shù)在時 間和空間上就保證了內(nèi)容的實時性和可看性。對于VR直播來說,技術(shù)才是保障它帶給用戶畫面即時、畫質(zhì)清晰、內(nèi)容精彩的必要因素,NextVR技術(shù)上的領(lǐng)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(zhì)的極高要求,VR直播比傳統(tǒng)的普通直播的技術(shù)參數(shù)高出近一倍,最少要2560*1440(2K)分辨率/30M碼率/90幀幀率。而且,現(xiàn)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(xiàn)場般的VR直播,用戶使用的網(wǎng)絡(luò)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(nèi)許多直播平臺都相繼開設(shè)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(shù)條件等因素限制,氛圍感受卻達不到相應(yīng)的效果,用戶體驗不佳。由于現(xiàn)階段技術(shù)上存在的不足,導(dǎo)致國內(nèi)VR直播提供不了畫質(zhì)清晰、流暢度好、結(jié)構(gòu)完整的內(nèi)容,這也是用戶詬病的重要原因。
另外,目前國內(nèi)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(shù)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(xiàn)眩暈感,而且手機長時間渲染VR視頻,往往會導(dǎo)致嚴重的發(fā)熱問題。因此,短時間內(nèi)國內(nèi)VR直播不能達到最低標(biāo)準(zhǔn),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(nèi)做VR直播的平臺應(yīng)該把重心都放在如何提高技術(shù)和優(yōu)化內(nèi)容上面,增加自身的實力才有競爭的資本。內(nèi)容和技術(shù)兩者是相輔相成,好的內(nèi)容需要提供技術(shù)支撐,好的技術(shù)需要優(yōu)質(zhì)內(nèi)容來填滿,NextVR為什么有資本傲視VR直播領(lǐng)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(yè)的發(fā)展,未來會有更多的廠商開發(fā)VR產(chǎn)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(xiàn)在。
