自从互联网上出现视频流以来，已经过去了大约 20 年。直到最近，视频流体验还有很多不足之处。在过去的几年里，这已经显着改善了流媒体货币化的可能性。最近，互联网上的商业视频传送服务呈爆炸式增长，有时称为 OTT 传送。所有这些服务都无一例外地使用流媒体技术。最初，流媒体有所有的希望，然后很长一段时间，它是下载和播放，后来是短内容的渐进式下载，现在又是流媒体。流媒体赢得了下载与流媒体的竞争吗？最好的技术获胜了吗？通过各种新的流媒体技术、一些专有技术和其他标准协议的扩展，流媒体体验的改进成为可能。娱乐视频（包括电影等优质内容和用户生成内容 (UGC)）的主要传输机制往往是 HTTP 流。 HTTP 流是解决所有问题的灵丹妙药吗？本文的目的是从行业角度阐述视频流媒体发生的根本性变化，使其具有商业可行性。本文概述了下载和流媒体之间的技术选择的结合如何使当前无处不在的流媒体浪潮成为娱乐视频传输的可能。在确定仍需要解决的问题后，本文总结了从视频流发展中汲取的经验教训。
It has been roughly 20 years since the beginning of video streaming over the Internet. Until very recently, video streaming experiences left much to be desired. Over the last few years, this has significantly improved making monetization of streaming, possible. Recently, there has been an explosion of commercial video delivery services over the Internet, sometimes referred to as over-the-top (OTT) delivery. All these services invariably use streaming technologies. Initially, streaming had all the promise, then for a long time, it was download and play, later progressive download for short content, and now it is streaming again. Did streaming win the download versus streaming contest? Did the best technology win? The improvement in streaming experience has been possible through a variety of new streaming technologies, some proprietary and others extensions to standard protocols. The primary delivery mechanism for entertainment video, both premium content like movies and user generated content (UGC), tends to be HTTP streaming. Is HTTP streaming the panacea for all problems? The goal of this article is to give an industry perspective of what fundamentally changed in video streaming that makes it commercially viable now. This article outlines how a blend of technology choices between download and streaming makes the current wave of ubiquitous streaming possible for entertainment video delivery. After identifying problems that still need to be solved, the article concludes with the lessons learnt from the video streaming evolution.
