-UMS serves media in two main ways - via DLNA/UPnP to be consumed via media player apps, and via HTTP(S) to be consumed via web browsers.
+UMS主要通过两种方式提供媒体服务——通过DLNA/UPnP供媒体播放器应用使用，以及通过HTTP(S)供网页浏览器使用。
 
-Web browsers have easy security and privacy control by having user accounts with logins.
+网页浏览器通过用户账号登录，可以方便地进行安全与隐私控制。
 
-Media player apps do not generally support the concept of a "user", so usually every device gets the same content. This might not be what you want. For example if you have two folders kids_safe and kids_unsafe you might want to restrict the renderers in the kids' room to only have access to the kids_safe folder. Another common situation is you are on the same network as people you do not want to have access to your media, like flatmates, so you want to block certain renderers completely.
+媒体播放器应用通常不支持“用户”概念，因此，一般而言每台设备都会获取相同的内容。 这可能不是你想要的。 例如，如果你有两个文件夹 kids_safe 和 kids_unsafe，你可能想要限制儿童房中的渲染器，使其只能访问 kids_safe 文件夹。 另一种常见情况是，你和不想让其访问你媒体的人（例如室友）处于同一网络，因此你想要完全屏蔽某些渲染器。
 
 UMS provides a number of methods to control access in those situations.
