信息技术 - UPnP设备架构 - 第27-1部分:友好的设备控制协议 - 友好的信息更新服务

[中文适用范围]： 此服务定义符合 UPnP 设备架构 1.0 版。它定义了一种服务类型，本文称为 FriendlyInfoUpdate 服务。该服务的范围限定于设备描述文档 (DDD)，允许控制点对 和 元素进行有序更新。 [外文原描述]： ISO/IEC 29341-27-1:2017 is compliant with the UPnP Device Architecture version 1.0. It defines a service type referred to herein as FriendlyInfoUpdate service . It is scoped to the Device Description Document (DDD) and is a service allowing control points to create orderly updates to the <friendlyName> and <iconList> elements. Once a change has taken place the status of the DDD might not reflect that of the advertised description because the device can not leave the network during ongoing activities. Therefore a state variable is provided to indicate if the DDD contains non-advertised (pending) values. If for any reason the device goes off line, power cycles, or reboots it will most likely advertise its new DDD. If DeviceProtection UPnP DP is implemented on the device then it will support restricting control point actions to control points with specific Roles.
