Embodiment 1

[0033] figure 1 The implementation process of the DLNA-based file playback method provided by the first embodiment of the present invention is shown, and the details are as follows:

[0034] In step S101 , a slave DLNA device sends an information request for obtaining a multimedia file being played by the master DLNA device to the master DLNA device.

[0035] In the specific implementation process, when a DLNA device is playing a multimedia file, the DLNA device that is playing the multimedia file is said to be the master DLNA device. If the user wants to continue playing the multimedia file in other DLNA devices (called slave DLNA devices) , and not limited to the location of the other DLNA device, then the other slave DLNA device can send an information request to obtain the multimedia file being played by the master DLNA device to the master DLNA device, for requesting the information of the multimedia file being played information.

[0036] In step S102, the slave DLNA d...

Embodiment 2

[0044] figure 2 The implementation flow of the DLNA-based file playback method provided by the second embodiment of the present invention is shown, and the details are as follows:

[0045] In step S201, the slave DLNA device sends to the master DLNA device a request for obtaining a storage address of a multimedia file being played by the master DLNA device.

[0046] In step S202, the master DLNA device converts the absolute path of the multimedia file into a URL address according to the request for obtaining the storage address of the multimedia file being played by the master DLNA device, or directly converts the URL address of the multimedia file from the player that is playing the multimedia file Obtain the URL address of the multimedia file, where the URL address is the storage address of the playing multimedia file.

[0047] Specifically, the master DLNA device judges whether the multimedia file corresponding to the request is stored locally, if so, converts the absolut...

Embodiment 3

[0059] image 3 The implementation process of the DLNA-based file playback method provided by the third embodiment of the present invention is shown, and the details are as follows:

[0060] In step S301, the master DLNA device receives an information request from the slave DLNA device for obtaining a multimedia file being played locally.

[0061] In step S302, the master DLNA device obtains the information of the multimedia file being played according to the request, and the information of the multimedia file includes the storage address of the multimedia file.

[0062] Wherein, the specific implementation process of step S302 includes:

[0063] The main DLNA device judges whether the multimedia file corresponding to the request is stored locally according to the request;

[0064] When the judgment result is yes, the absolute path of the multimedia file is converted into a URL address;

[0065] When the judgment result is no, directly obtain the URL address of the multimed...

Abstract

The invention is suitable for the technical field of multimedia playing, and provides a file playing method and system based on DLNA (Digital Living Network Alliance) and driving and driven DLNA equipment. The method comprises the following steps that the driven DLNA equipment sends an information request for obtaining a multi-media file playing by the driving DLNA equipment to the driving DLNA equipment; the driven DLNA equipment receives the information of the multi-media file returned by the driving DLNA equipment according to the request, and the information of the multi-media file comprises the memory address of the multi-media file; and the driven DLNA equipment plays the multi-media file according to the memory address in the information of the multi-media file. The method uses the driven DLNA equipment to obtain the information of the multi-media file playing by the other driving DLNA equipment, so that the content playing by the other driving DLNA equipment is transferred to other DLNA equipment to be continuously played, users can watch the content that the users want to watch at any time, and the user experience is enhanced.

Description

technical field [0001] The invention belongs to the technical field of multimedia playing, and in particular relates to a DLNA-based file playing method and system, and master and slave DLNA devices. Background technique [0002] At present, there are more and more applications of multi-screen interaction, and many TV manufacturers or mobile device manufacturers are adopting it. And DLNA (Digital Living Network Alliance, Digital Living Network Alliance) is undoubtedly a framework agreement that various applications should abide by. DLNA itself is a solution, a series of technical specifications such as sharing media and controlling media playback, and the various technologies and protocols selected by it are widely used technologies and protocols at present. DMR (Digital Media Renderer, Digital Media Renderer) is a functional module of DLNA, which can accept the control of other DLNA devices (device with DLNA function) to play media files. When a media file browsed from a ...
