DLNA指南第1至3部分介绍了许多设备类别，以确定特定的 连接的端点在网络中实现的角色。设备可以充当内容源 （例如，数字媒体服务器、推送控制器）和内容接收器（数字媒体渲染器） 或数字媒体播放器）。拥有两种类型的内容接收器是一种有效的策略，可以加速初始阶段 部署阶段。然而，许多现代接收器设备现在都包括这两种类型。 因此，需要定义结合这两种类型的接收器设备。BS IEC 62481-1-2:2017解决了这个问题，特别是描述了扩展设备的设备类别 数字媒体渲染器（XDMR）和组合数字媒体的实施指南 渲染器和UPnP媒体服务器控制点。交叉引用:ISO/IEC 29341-3-11:2008 Ed 1IEC 62481-3:2017IEC 62481-2:2017ISO/IEC 29341-3-10:2015IEC 62481-4:2017IEC 62481-1-1:2017ISO/IEC 29341- 3-13:2008 Ed 1ISO/IEC 29341-1购买本文件时可获得的所有现行修订均包含在购买本文件中。

The DLNA Guidelines Parts 1 to 3 introduce a number of device classes to identify specific roles that connected endpoints implement in the network. Devices can act as content sources (e.g., Digital Media Servers, Push Controllers), and as content sinks (Digital Media Renderers or Digital Media Players).Having two types of content sinks has been a useful strategy to accelerate the initial deployment phase. However, many of the modern receiver devices now include both types. Consequently, there is a need to define a receiver device that combines both types. BS IEC 62481-1-2:2017 addresses this issue and, specifically, it describes a device class for an Extended Digital Media Renderer (XDMR) and implementation guidelines for combining a Digital Media Renderer and a UPnP Media Server Control Point.Cross References:ISO/IEC 29341-3-11:2008 Ed 1IEC 62481-3:2017IEC 62481-2:2017ISO/IEC 29341-3-10:2015IEC 62481-4:2017IEC 62481-1-1:2017ISO/IEC 29341-3-13:2008 Ed 1ISO/IEC 29341-1All current amendments available at time of purchase are included with the purchase of this document.
