Three, central server 1 sends the step of data to multimedia advertising terminal 3:
Existing mobile communication network can satisfy information such as real-time Transmission MPEG4 image, literal news, for the bigger stream of audio-visual data of some bandwidth requirements, then adopts and downloads the mode that play the back, because the requirement that advertisement is play does not need real-time Transmission; And transmitting real-time literal news, the bandwidth foot is satisfied.Along with the development of public radio communication network (as following 3G or 4G net open-minded), bandwidth can satisfy the real-time Transmission stream of audio-visual data, but real-time online is play high-quality movable video information.
The information (media stream file data, message data, order data) that the device editor of management and control multimedia advertising terminal 3 need transmit in the central server 1, and with the suitable form that transmits of this information translation one-tenth, and mat public wireless communication network 2 sends to the specific multimedia advertising terminal 3 of passing through check, and this specific multimedia advertising terminal can be one or more.
Four, multimedia advertising terminal 3 receives the step of data:
The wireless communication module 31 of multimedia advertising terminal 3 is passed to flush bonding processor 32 with these data by the RS232 bus after receiving the next data of central server 1 transmission; Flush bonding processor 32 recovers original form with these data that receive, and judges the type of these data, has defined three kinds of data types in the present embodiment, and one is a file data, i.e. the media stream file data; It two is an order data, i.e. the control command and the querying command of 1 pair of this multimedia advertising terminal 3 of central server; The message data of another real-time news messages.If what receive is the media stream file data, then this media stream file data is transferred to multimedia audio-video decoder 330, store in the hard disk 35 by this multimedia audio-video decoder 330; If what receive is order data, as playing programs arrangement instruction, then it is according to the particular content of order, and control multimedia audio-video decoder 330 is made corresponding action, for example plays the program that is stored in the hard disk 35; If what receive is message data, then controls multimedia audio-video decoder 330 and broadcast or be stored in the hard disk 35 in the mode of rolling literal.
The return information of 330 pairs of central servers 1 of audio/video decoder, can send central server 1 to according to above-mentioned reversible process, be the return informations of audio/video decoder 330 editors to central server 1, utilize flush bonding processor 32 format transformations and encryption, and send by wireless communication module 31.
Five, the step of central server 1 and multimedia advertising terminal 3 time synchronized:
In each multimedia advertising terminal 3, all carry out the real-time clock management, can receive the forced synchronism order of central server 1, keep time synchronized with central server 1.
The utility model is except the information issue that is applied to stationary applica-tions, can also be applied to be on the mobile occasion, as releasing news on the vehicle car that is in mobile status at the passenger traffic bus of traffic between city bus vehicle, railcar, city, rail vehicles for transporting passengers etc.
Compared with prior art, the utlity model has following beneficial effect:
1, in the utility model, 1 base of the central server of multimedia advertising terminal 3 and its wireless connections In the networking mode of server/customer end (Server/Client), adopt open tcp/ip communication agreement Communicate; The tcp/ip communication agreement can guarantee the transmission of each packets of information, so multi-media broadcast comes to an end End 3 does not receive the data that central server 1 sends with can both correctly having omission.
2, each multimedia advertising terminal 3 is connected in the network tool with central control server 1 At any time the control of accepting central server 1 is arranged, carry out the order of central server 1, show central service The real-time Word message that device 1 sends carries out file transfer, receives the file that central server 1 is downloaded, At any time upload the functions such as state of self. To the monitoring of advertisement terminal, can be in by the authorization login The centre server by the application/management software in the operation central server, is realized control and prison to terminal Depending on.
3, the utility model multimedia advertising terminal is used 32 Embedded RISC microprocessing units, all On the embedded OS of application software operation based on a powerful network function, the microprocessing unit computing Ability is strong, the increase of system upgrade, function and only improve must software renewal can realize.
4, the medium of the utility model file adopts local hard drive, its anti-seismic performance, access Speed, memory capacity are all better than CD drive, and cost is suitable even lower. The utility model is adopted Use the broadband mobile transfer of data, except Word message, can also transmit the still picture of high-resolution, in real time literary composition Word news is play, and real-time online is play the movable video of MPEG4 of high compression rate, utilizes the 3G Mobile data Transmission, but real-time online is play high-quality movable video information.
