Abstract

The invention is applied to the technical field of DLNA (digital living network alliance), and provides a multimedia file playing method, a multimedia file playing system and a DMR (digital multimedia renderer). The system comprises a DMC (digital multimedia controller), the DMR and a DMS (digital multimedia server). The method comprises the steps that the DMC transmits file addition information to the DMR; the DMR acquires the information of a multimedia file set, and adds the multimedia file set into a first playing list; the DMR acquires the information of a multimedia file with the highest priority from the first playing list if not receiving playing request information from the DMC within a preset time after the playing of any one multimedia file is finished, downloads the multimedia file with the highest priority from the DMS according to the information of the multimedia file with the highest priority, and plays the multimedia file with the highest priority. According to the method, the system and the DMR, playing delays of the multimedia files are reduced, the multimedia files can be continuously played, and meanwhile, misoperation is effectively prevented.

Description

technical field [0001] The invention belongs to the technical field of DLNA (Digital Living Network Alliance, Digital Living Network Alliance), and in particular relates to a multimedia file playback method, system and digital multimedia renderer. Background technique [0002] In the prior art, when DLNA adopts PUSH mode to play multimedia files, a playlist is usually set up in DMC (DigitalMultimedia Controller, digital multimedia controller), and DMC needs to continuously push multimedia to DMR (Digital Multimedia Renderer, digital multimedia renderer). document. That is, after the DMR finishes playing a multimedia file, the playing state changes to the stopped state, and when the DMC detects that the playing state of the DMR is in the stopped state, it selects a multimedia file from the playlist and pushes it to the DMR. [0003] When the stop button of the DMR receives an instruction to stop playing from the user, it indicates that the user wants the DMR to stop playing ...
