The display end includes display end socket server-side, display control system.
As a further solution of the present invention: the display control system includes but is not limited to the volume for controlling display end
Plus-minus and audio-video output.
As further scheme of the invention: the display end is specially that DLNA is supported to throw the display equipment of screen broadcasting.
As further scheme of the invention: the DMS refers to data base management system；DMR refers to that Digital Media connects
Receive device.
As further scheme of the invention: the control flow of wired throwing screen based on DLNA is specific as follows:
(1) the video APP of mobile phone terminal is opened, and controls video APP and opens DLNA background service DMR, monitors video in real time
The data and control information of the end the DMS transmission of APP；
(2) mobile phone terminal socket server-side, socket client are transmitted for data in video APP in mobile phone terminal, and will
Data are transmitted to usb data line；
(3) display end socket server-side receives in the shown end of data that mobile phone terminal is transmitted by usb, is transferred to display
Device control system, display control system obtain mobile phone terminal audio, video data and control information after, control audio-video broadcasting and
The adjusting of volume.
Compared with prior art, the beneficial effects of the present invention are:
Wired throwing screen based on DLNA of the invention is obtained the audio-video of video APP using DLNA agreement, cleverly avoided
Rights concerns, due to the primary support screen projection function of the agreement, it cannot be carried out to mobile phone when same screen by solving user
The pain spot that it is operated, user can carry out other operations with mobile phone when wired throwing screen, not interfere with display end sound view
Frequency evidence and and control information acquisition, easily display end can be controlled, if volume add and subtract, audio and video playing etc..
Detailed description of the invention
