媒体服务的功能是什么?What can I do with Media Services?

使用媒体服务,你可以在云中构建各种媒体工作流。Media Services lets you build a variety of media workflows in the cloud. 下面是媒体服务的功能的一些示例:Some examples of what you can do with Media Services include:

  • 提供各种格式的视频,以便通过各种浏览器和设备播放视频。Deliver videos in various formats so they can be played on a wide variety of browsers and devices. 为了将点播和实时传送视频流传输到各种客户端(移动设备、电视、电脑等),需要对视频和音频进行适当的编码和打包。For both on-demand and live streaming delivery to various clients (mobile devices, TV, PC, and so on), the video and audio content needs to be encoded and packaged appropriately. 要了解如何交付和流式传输此类内容,请参阅快速入门:编码和流式传输文件To see how to deliver and stream such content, see Quickstart: Encode and stream files.
  • 向大量在线观众流式传输实时体育赛事,例如足球、棒球、大学和高中体育运动等等。Stream live sporting events to a large online audience, like soccer, baseball, college and high school sports, and more.
  • 广播公共会议和活动,例如市政厅、市议会和立法机构。Broadcast public meetings and events, like town halls, city council meetings, and legislative bodies.
  • 当客户(例如电影工作室)需要限制对版权所有作品的访问和使用时,创建订阅视频服务并流式传输受 DRM 保护的内容。Create a subscription video service and stream DRM protected content when a customer (for example, a movie studio) needs to restrict the access and use of proprietary copyrighted work.
  • 提供脱机内容,以便在飞机、火车和汽车上播放。Deliver offline content for playback on airplanes, trains, and automobiles. 如果客户希望断开网络连接,可能需要将内容下载到手机或平板电脑上播放。A customer might need to download content onto their phone or tablet for playback when they anticipate to be disconnected from the network.
  • 使用 Azure 媒体服务和 Azure 认知服务 API 实现教育在线学习视频平台,提供语音转文本字幕、多种语言翻译等功能。Implement an educational e-learning video platform with Azure Media Services and Azure Cognitive Services APIs for speech-to-text captioning, translating to multi-languages, and so on.
  • 将 Azure 媒体服务与 Azure 认知服务 API 配合使用来为视频添加字幕和描述文字,满足更多受众的需求(例如,听力障碍人士或想用不同语言阅读的人)。Use Azure Media Services together with Azure Cognitive Services APIs to add subtitles and captions to videos to cater to a broader audience (for example, people with hearing disabilities or people who want to read along in a different language).
