What Is Streaming Video 'Delivery?'

Article Featured Image

I如果你在流媒体视频行业呆过一段时间,你很快就会听到“交付”这个词." In fact, it's used quite often to describe the technologies, processes, mechanisms, 供应商参与传输比特和字节的数据,以响应用户对视频片段的请求.

但视频的“交付”一词并不总是那么集中. In the television space, for example, 传送意味着很多事情:将信号从摄像机传送到剪辑车, getting the edited feed to the downlink facility, 将内容从版权所有者那里送到生产设施(这些“数字日报”过去是手工交付的) videotapes), etc. Delivery, outside of streaming video, involves the entire 为观众提供他们可以观看的体验的系统. 

The streaming video industry, though, 已经剥离了很多,并将交付减少到仅仅是一个技术过程. 当流媒体行业的人谈论交付时, 他们只关心协议和网络传输. 尽管这些都是提供优质流媒体体验的重要组成部分, 它们只是提供这种服务的一个方面. 

Consider the user experience, for example. In a recent Chicago Tribune 在文章中,作者询问了人们对流媒体应用的感受. 总的来说,大家的共识是,“有时有效,有时无效。." They crash. Streams end abruptly. Quality is hit and miss. The gist of the Tribune的故事是,人们可以在很多设备上观看流媒体内容, and yet, the viewing experience, the experience that is being delivered by the streaming operator, is incredibly inconsistent. 这在广播电视上已经不再发生了.

当然,有人可能会说流媒体比传统电视复杂得多. With broadcast TV, 将内容从广播机构或多系统运营商(MSO)传送到最终用户只需要几个组件. 用户不需要在手机或平板电脑上观看内容的微型机顶盒. There is just one set-top box, 解密和显示内容所需的一切都是内置的. 

Streaming, though, 是一个技术联盟:用于编码和解码的编解码器, transcoders, watermarking technology, DRM technology, ad-insertion technology, apps for different operating systems and devices, 用于浏览器查看的网页(必须支持多个浏览器), etc. 想象一下,如果你家里的每个房间都不一样,传统的广播公司不得不量身定制广播内容. It would be a nightmare. 

但这正是我们需要扩大流媒体视频中“交付”定义的原因 为用户提供观看体验所涉及的一切. 它是他们流媒体的网页或应用程序. It's the delivery of bits. 它是安全的(如果用户已经授权了某些东西,他或她不能观看), that's a bad experience). It's the delivery of advertising. 流媒体视频传输不仅仅是比特、字节、协议或cdn. It's all-encompassing, 哪个等同于观看者想要观看的视频的整体体验. 

This may seem like I'm quibbling, but words matter. 一个行业的词汇可以帮助每个人使用相同的语言,这样当我们谈论需要解决的问题时, there's no question. 但是一个词汇也可以是包含的或排除的. 目前,“交付”一词在流媒体视频行业的使用是排他性的. 如果我们要朝着流媒体取代传统广播迈出下一步, 然后,我们需要开始在谈论交付时更多地包括整体体验. 因为如果我们继续这种简化的方法,“传递”就只是关于协议和字节, 我们将永远把流媒体作为传统电视的二把手.
