Digital living network alliance (DLNA) equipment demonstration system and method based on DLNA protocol

Abstract

The invention discloses a digital living network alliance (DLNA) equipment demonstration system and a method based on a DLNA protocol. The method based on the DLNA protocol includes the steps: A, structuring a digital media server based on DLNA protocol connection; B, establishing communication connection between a digital media player and the digital media server based on the DLNA protocol; C, controlling synchronization information of the present powerpoint through a digital media controller, and the synchronization information is synchronously displayed on the digital media player correspondingly, wherein the synchronization information of the present powerpoint is obtained from the digital media server from the digital media player. According to the DLNA equipment demonstration system and the method based on the DLNA protocol, the DLNA protocol connection is established between the digital media server and the digital media player and between the digital media player and the digital media controller, the synchronization information of the present powerpoint is controlled through the digital media controller, and the synchronization information is synchronously displayed on the digital media player correspondingly, wherein the synchronization information of the present powerpoint is obtained from the digital media server from the digital media player. Compared with the prior art, the DLNA equipment demonstration system and the method based on the DLNA protocol is capable of solving the problems that the displayed content which can not be seen clearly on the corresponding projection equipment by participated people is caused by limits of distances and angles in the present demonstrated process.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a DLNA device demonstration system and method based on the DLNA protocol, which is mainly used to realize that various DLNA devices can watch demonstration files during a demonstration and achieve good demonstration effects. Background technique [0002] With the continuous development of science and technology, more and more electronic devices are used in daily life, such as projectors, tablet computers, digital cameras, video cameras, computers, multimedia players, game consoles, mobile phones, etc. Usually, there are different files stored on these devices, such as various audio, photo, video and PPT presentations, etc. If the user wishes to watch or appreciate the files stored on one of these electronic devices, he must It can be realized after processing with corresponding processing software. [0003] The emergence of the Digital Living Network Alliance (DLNA) has...
