Abstract

The invention discloses a method, device and system for acquiring a media file and being applied to a DLNA system. The method includes the following steps of: sending a browsing command request to a digital media server DMS to ask the DMS to return a first media file of a default type in a root directory and under a default directory of the DMS and a folder of a second media file containing the default type in the root directory; and receiving a browsing command response returned by the DMS, and acquiring the first media file and the folder from the browsing command response. According to the invention, the problem that the DMS cannot filter out the folder of the media file containing the default type, can be solved, the pushing time of the media file can be saved, and the user experiences can be improved.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method, device and system for acquiring media files applied to a DLNA system. Background technique [0002] In recent years, Digital Living Network Alliance (DLNA) technology has been extensively developed, and more and more media devices, audio-visual terminals and playback platforms all support DLNA technology. This technology allows devices to discover devices with other functions when they are connected to the network, and view and share media resources in the server to a player for playback. The types of DLNA devices mainly include Digital Media Player (Digital Media Player, DMP), Digital Media Renderer (Digital Media Renderer, DMR), Digital Media Server (Digital Media Server, DMS) and Digital Media Controller (Digital Media Controller, DMC) . The DMC device includes a DLNA control point, which can browse the media files shared in the DMS, and push ...
