Description

 System

J. (Digital Living Network Alliance, now

 Universal Plug and Play (UPnP) is an architecture for common peer-to-peer network connections for PCs and smart devices (or instruments), especially in the home. Based on Internet standards and technologies such as TCP/IP, HTTP, and XML, UPnP enables such devices to automatically connect and work with each other. Network devices can be classified into Media Server (DMS), Media Controller (DMC), and Digital Media Render (DMR) by function.

 The DMS is configured to provide sharing of media content in the home network. It includes the Connection Management Service (CMS), the Content Directory Service (CPS), and the AV Transport Service (AVT). The connection management service is used to establish a network connection between the media controller and the media server; the content directory service is used to manage the media data in the media server. The audio and video transmission service is used for transmission control of media data between the media controller and the media server.

 The DMC is configured to manage other media server settings and media renderer devices in the home network. When a DMS and a DM join or exit the UPnP network, the DMC can update the device list in time; the DMC also needs to support browsing the media content shared by the DMS. And can specify DMR to play, play. The process can be controlled by DMC.

The DMR is configured to render media content obtained in the home network. Contains the following business: rendering Rendering Control Service (RCS), CMS, and AV. The connection management service implements media media protocol and media format negotiation with the media server, and the audio and video transmission service completes the playback process control, and the rendering control service controls the rendering characteristics, such as brightness, contrast, bone mass, and the like.

 DMS, DMC, and DMR can be used as stand-alone applications or integrated. The same application of the same terminal can have the functions of DMSZDMC/DMR at the same time.

 At present, with the improvement of living standards and the development of tourism, more and more people choose to travel during holidays. In the tourist attractions, when visitors enter a certain scenic spot, they need to know the detailed introduction of the attraction, and they are usually guided tours. Take on this role.
