Universal access to and provisioning of multimedia content is now a reality. It is easy to generate, distribute, share, and consume any multimedia content, anywhere, anytime, or any device. Open media standards took a crucial role toward enabling all these use cases leading to a plethora of applications and services that have now become a commodity in our daily life. Interestingly, most of these services adopt a streaming paradigm, are typically deployed over the open, unmanaged Internet, and account for most of today’s Internet traffic. Currently, the global video traffic is greater than 60% of all Internet traffic [1] , and it is expected that this share will grow to more than 80% in the near future [2] . In addition, Nielsen’s law of Internet bandwidth states that the users’ bandwidth grows by 50% per year, which roughly fits data from 1983 to 2019 [3] . Thus, the users’ bandwidth can be expected to reach approximately 1 Gb/s by 2022. At the same time, network applications will grow and utilize the bandwidth provided, just like programs and their data expand to fill the memory available in a computer system. Most of the available bandwidth today is consumed by video applications, and the amount of data is further increasing due to already established and emerging applications, e.g., ultrahigh definition, high dynamic range, or virtual, augmented, mixed realities, or immersive media applications in general.

开放媒体压缩特刊：概述、设计标准和新兴标准展望

对多媒体内容的普遍访问和供应现在已成为现实。随时随地或任何设备都可以轻松生成、分发、共享和使用任何多媒体内容。开放媒体标准在实现所有这些用例方面发挥了至关重要的作用，导致大量应用程序和服务现在已成为我们日常生活中的一种商品。有趣的是，这些服务中的大多数都采用流模式，通常部署在开放、不受管理的 Internet 上，并占当今 Internet 流量的大部分。目前，全球视频流量超过所有互联网流量的 60%[1] ，并且预计在不久的将来这一份额将增长到80%以上 [2] . 此外，尼尔森互联网带宽定律指出，用户的带宽每年增长 50%，大致符合 1983 年至 2019 年的数据[3] . 因此，预计到 2022 年用户的带宽将达到大约 1 Gb/s。与此同时，网络应用程序将增长并利用所提供的带宽，就像程序及其数据扩展以填充计算机系统中可用的内存一样. 今天的大部分可用带宽都被视频应用程序消耗，并且由于已经建立和新兴的应用程序，例如超高清、高动态范围或虚拟、增强、混合现实或沉浸式媒体应用程序，数据量正在进一步增加。一般的。
