ISO/IEC 29341-14-3:2011（E）是符合UPnPTM设备架构1.0版的设备规范。它定义了本文中称为MediaServer的设备类型。MediaServer规范定义了一种通用设备，可用于实例化向家庭网络上的其他UPnP设备提供AV内容（例如媒体）的任何消费电子（CE）设备。它基于UPnP AV架构框架（另一份文档中描述）。它通过ContentDirectory服务公开其内容（有关详细信息，请参阅ContentDirectory服务规范）。MediaServer还可以提供使用ScheduledRecording服务记录内容的功能（请参阅ScheduledRecording服务规范）。 因此，MediaServer可以处理任何特定类型的媒体、任何数据格式和传输协议。

ISO/IEC 29341-14-3:2011(E) is a device specification compliant with the UPnPTM Device Architecture version 1.0. It defines a device type referred to herein as MediaServer. The MediaServer specification defines a general-purpose device that can be used to instantiate any Consumer Electronics (CE) device that provides AV content (for example, media) to other UPnP devices on the home network. It is based on the UPnP AV Architecture Framework (described in another document). It exposes its content via the ContentDirectory service (refer to the ContentDirectory service specification for details). The MediaServer MAY also provide functionality to record content using heScheduledRecording service (refer to the ScheduledRecording service specification). As such, the MediaServer can handle any specific type of media, any data format, and transfer protocol.
