This course helps those new to streaming media get familiar with the relevant terms, concepts, and technologies. 会议从定义编解码器等术语开始, container formats, 和自适应比特率流, 以及像比特率控制(VBR)这样的编码概念, CBR)和框架类型(I, B, and P). 然后详细描述键H.264编码参数影响质量和兼容性. 下一个是自适应流媒体, 包括对HLS和DASH等现有ABR技术的回顾, 如何制定一个编码阶梯, 以及如何使用多个drm来保护优质内容. 然后我们将回顾ABR交付到计算机的技术要求, 智能手机和平板电脑, OTT devices, and smart TVs, 并快速查看HEVC等高级编解码器, VP9, AV1, and VVC. You walk away knowing the technical requirements for delivering to all key platforms and an understanding of how to do so.

This workshop teaches you how to use and configure the essential (and purposely redundant) components of a live streaming event system. 演示展示了来自不同供应商的硬件，包括相机、H.264 encoders/streamers, video switchers, video signal conversion, recorders, and more. You also learn how to best deploy the live stream to your audience based on business requirements: Do you utilize free social media outlets, 使用优质的第三方流媒体服务, 或者建立自己的直播基础设施? Learn how to approach different live scenarios with the right gear to fit the budget you have. 也许更重要的是, learn how to properly formulate a budget to avoid any common pitfalls in the process.

The concept of a single set of files deliverable to all relevant endpoints has been the Holy Grail since the dawn of ABR streaming. By mid- 2019, 通用媒体应用格式(CMAF)将实现这样的解决方案, slashing encoding, storage, 以及部署它的公司的带宽成本. In this workshop, you learn how to create CMAF packaged assets for HLS and or DASH and get a greater understanding of the benefits CMAF has to offer. 我们从H的行业基线开始.基于264的CMAF内容, then offer insight and direction on how to handle more complex and emerging solutions. We briefly cover how to extend what you learned to alternate codecs starting with VP9, 然后是4K编码, packaging, 并以HEVC或AV1交付. We also touch on some of the considerations and challenges with HDR encoding and delivery. Last but not least, 我们涵盖了细节和“如何”知识，以保护您的CMAF内容与DRM, 包括你需要知道的关于CENC的信息, CBCS, CTR, and working toward truly fulfilling the vision for unified common encryption DRM on the horizon.

This session helps encoding professionals get up-to-speed on crucial encoding-related issues, technologies, and techniques. Topics include:

Encoding workflows for nearly every video ecosystem can utilize powerful and free open source options, such as FFmpeg, which appeal to startups and established businesses for the flexibility in customization that it offers. This presentation explores extended encoding options for FFmpeg including libx264 (AVC/H.264)和libx265 (HEVC/H . 264).265)，以最大限度地兼容各种移动和桌面浏览器, 还有流媒体服务器. Learn how to use filter effects, proportional crop/resize options, and mapping functions. 在下一次编码管道升级中利用FFmpeg的强大功能!

Machine learning as a service (MLaaS) is a subset of artificial intelligence (AI) and has come a long way over the last couple years. Now is the time to really make these services work for you and increase the ROI on your media. 你是否想提高视频的可搜索性和可发现性, 自动化生成文本和翻译的过程, or even look for specific faces or people within your live surveillance streams in an efficient manner, the key to harnessing this power is to learn to determine your needs and code against the numerous available MLaaS APIs to make them work for you. 本次研讨会回顾了2019年MLaaS的格局, 探索驱动他们创新的用例, 并讨论各种可供您使用的百家乐软件和开放源代码. Attendees walk away with an understanding of how to harness the power of AI machine learning to increase the ROI of their video libraries and build compelling and innovative intelligence from their libraries of dark media data.
