Embodiment 1

[0052] DLNA Digital Living Network Alliance (Digital Living Network Alliance; hereinafter referred to as: DLNA) is a set of standard solutions formulated to facilitate people's digital home entertainment life. In media playback and sharing, DMS devices involved are implemented by DMS applications. The directory content management module and the media playback transmission control module are composed. The DMC device is implemented by the DMC application. It is a control node. Its main body is the playback and rendering control module and the DMS content query index module. The DMR device is implemented by the DMR application. Its core is The media rendering module realizes the interaction between the media rendering module and the media driver interface, calls the software and hardware decoder through the media driver interface to realize the final decoding and rendering output process of the media, and the DMP device is a DMR device with DMC application function.

Embodiment 2

[0067] The second embodiment discloses a system for grouping and simultaneously controlling multiple media devices through DLNA, including the following devices:

[0068] 1. DLNA network initialization device,

[0069] The device is used for establishing a data transmission channel between DMC equipment and DLNA network, searching for DMS equipment and DMR equipment in the DLNA network, and classifying and displaying the searched DMS equipment and DMR equipment.

[0070] At the same time, after the DMC device and the DLNA network establish a data transmission channel, the DLNA network initialization device is also monitoring the status of the DMS device and the DMR device in the DLNA network in real time in the background, detecting whether there is a device exiting or joining, and updating the status of the DMS device and the DMR device. The category list is displayed.

[0071] Among them, the ways of establishing data transmission channels include Bluetooth, WiFi, USB and r...

Abstract

The invention discloses a method for simultaneously controlling multiple media devices in a grouped mode through the DLNA. The method includes the following steps: a DMC device and the DLNA network build a data transmission channel, and the DMS devices and the DMR devices in the DLNA network are searched and displayed in a classified and listed mode; a user creates groups according to requirements, and meanwhile corresponding device lists in the groups are associated in the background; the groups in the DMR device list are selected; multimedia files of the DMS devices are browsed and selected for playing, URL resource address information, media transmission protocols and media formats of the multimedia files are obtained, URL resource addresses of the multimedia files selected for displaying are set in the selected DMR devices, and the multimedia files are played. By means of the method, grouping management can be carried out on the DMR devices, the DMR devices in different groups can play the same multimedia files at the same time, the playing states of the DMR devices in the selected groups can be controlled, flexibility is achieved, and the requirements for diversification and personalization can also be met.

Description

technical field [0001] The invention relates to the technical field of network multimedia interconnection, in particular to a method and system for realizing grouping and simultaneously controlling multiple media devices through DLNA. Background technique [0002] The full name of the Digital Living Network Alliance DLNA is DIGITAL LIVING NETWORK ALLIANCE, which aims to enable devices in the same network domain to realize free cross-device multimedia playback by integrating existing technologies and network protocols. For example, a mobile phone can be used to control a Blu-ray disc player to play multimedia file resources on a PC or other servers, making digital multimedia sharing and playing more convenient and quick. According to the current application, the DLNA network is mainly a local area network composed of household devices directly connected to the same wireless / wired router through WIFI, LAN and other access methods. The household equipment (DLNA equipment) in t...
