企业级直播带货时代来临:VR/AR视频直播在全球发布会中创造无限可能
VR虚拟直播、AR视频直播
拓源新思视觉技术团队,为您在全球范围内打造各种超现实的线上发布会,并将流量分发至各视频平台,让带货发布直接改变未来营销趋势。
因为疫情的传播,导致很多企业计划内的发布会,不得不取消。
最近几个在行业有超前影响力的发布会,给我们带来了全新的视野。
一个是:小米的手机发布会,雷军通过一场现场无人参加的在线直播做了一个首开先河的发布会,跟时间做了一次赛跑。
接下来,更酷的是三星手机发布会,直接用自带的软件,进行了AR直播。成熟的抠像技术配合虚拟3D场景,让你仿佛置若现场。
关键的是,成本超低到你想像。
与其在没有人的现场搭建舞台花费,不如拿这个钱去买流量---这个,显然比雷军更胜一筹。
进行直播,为了能达到更好的视觉效果,往往要借助VR或AR直播技术。
VR是指360全景直播,利用360全景摄像设备,将你置身舞台现场,配上专用的VR眼镜,就可以有身临其境的感觉了。
而AR是指增强现实技术,让虚拟的场景与真实的人物揉合到一块,并通过实时渲染设备,就打造了一个没有真实舞台的“真实”场景了。
关于AR设备的详细描述:Vizrt AR做为全球领先的AR增强现实系统,适用范围广、应用领域多、可靠性高,可以为综艺、体育赛事节目提供炫酷的AR包装。如CCTV、FOX、BBC、SKY、ESPN等全球知名电视台,均采用Vizrt的AR和在线包装系统,尤其在电竞领域,拳头和暴雪两家公司所有的电竞赛事,在线包装和虚拟AR均使用Vizrt系统。国内腾讯的英雄联盟、王者荣耀的大型赛事所有炫目耀眼的AR效果,都是通过Vizrt系统实现的。

提起VR直播,很多人都不会忘记去年科比职业生涯最后一场NBA比赛。NextVR利用VR直播技术,让不能亲临现场的球迷也能感受到比赛中海啸般的欢呼呐喊声,身临其境的感受比赛上的激烈,见证科比退役的那一瞬间。如今,NextVR开放了VR直播观看资格,所有用户都能付费观看每一场NBA全明星比赛。
随着技术的发展,VR也在由科技概念变成商业现实。VR直播是虚拟现实与直播的结合,VR直播是怎么实现的呢?简而言之,其从拍摄到观看的全流程可以概括为:全景相机+拼接合成服务器+编码上传+点播机房分发+用户收看。具体来说,全景相机采集视频数据后通过电脑或者工作站进行实时拼接,再经过编码推到机房进行分发,最后是用户通过VR头盔+手机/电脑进行观看。在这个流程中,除了全景相机和拼接环节,VR直播与传统直播并没有太多区别。
VR直播对设备的要求较高,从流程、拍摄端,传输到云端分发,到播放端,头盔,端到端,还有视频的应对,几乎每一个环节都要求甚高。VR直播需要采用360度全景的拍摄设备,不仅要有多颗广角镜头,还要传感器同步、色彩及白平衡参数一致,以捕捉超清晰、多角度的画面,每一帧画面都是一个360度的全景,普通的手机摄像头和PC摄像头难以满足拍摄要求。
随着科技的发展,VR直播所需的设备也在逐渐发展,VR摄像机已经有商业技术解决方案,像得图F4和诺基亚OZO等都可以进行VR直播。诺基亚OZO价格大约4.5万美元,对于一般人而言有些昂贵,但是对于电视台、影视制作公司等专业平台来说并不算太贵。也就是说,在VR摄像机上已经不存在难题,难就难在VR直播最核心的画质和实时拼接问题。
走在VR直播最前沿的是美国的NextVR,其有拍摄、压缩、传输和VR内容显示等26项专利做技术支撑。除了拥有数据压缩技术,NextVR还拥有一款专门用于实时转播360度VR节目的全景直播卡车,这两项技术在时 间和空间上就保证了内容的实时性和可看性。对于VR直播来说,技术才是保障它带给用户画面即时、画质清晰、内容精彩的必要因素,NextVR技术上的领先直接拉开了它和其他竞争对手的差异。
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.
由于对画质的极高要求,VR直播比传统的普通直播的技术参数高出近一倍,最少要2560*1440(2K)分辨率/30M码率/90帧帧率。而且,现有条件下,使用PC客户端+VR头显才能提供最好的临场沉浸体验、最逼真的3D视角效果。另外,用户想要观看亲临现场般的VR直播,用户使用的网络带宽必须大于VR视频的码率,如果是2K分辨率,用户实际的下行带宽至少大于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.
虽然国内许多直播平台都相继开设了VR直播频道和VR直播间,还有许多明星的演唱会推出VR直播,但是因技术条件等因素限制,氛围感受却达不到相应的效果,用户体验不佳。由于现阶段技术上存在的不足,导致国内VR直播提供不了画质清晰、流畅度好、结构完整的内容,这也是用户诟病的重要原因。
另外,目前国内涉足VR直播的都是一些直播平台,各个平台没有为VR直播做好技术储备,分辨率、刷新率和码率都不够,而且大部分用户使用的手机观看VR直播,而不是VR头显,由于手机本身的低分辨率、低刷新率限制,使用手机VR盒子时间稍长就会出现眩晕感,而且手机长时间渲染VR视频,往往会导致严重的发热问题。因此,短时间内国内VR直播不能达到最低标准,也无法满足用户的需求。
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,国内做VR直播的平台应该把重心都放在如何提高技术和优化内容上面,增加自身的实力才有竞争的资本。内容和技术两者是相辅相成,好的内容需要提供技术支撑,好的技术需要优质内容来填满,NextVR为什么有资本傲视VR直播领域,这就是它成功的因素。
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.
随着VR行业的发展,未来会有更多的厂商开发VR产品,我国的VR直播市场也会越来越大,最后各平台的VR直播都能达到市场水平,只是需要时间,而不是现在。
