A kind of deficiency of the present invention for existing broadcast technology, there is provided integrated information broadcaster based on DTMB transmission platforms
Method, to make the purpose of the present invention, technical scheme and effect clearer, clear and definite, below the present invention is described in more detail.Should
Work as understanding, specific embodiment described herein only to explain the present invention, is not intended to limit the present invention.
Integrated information broadcasting method based on DTMB transmission platforms as shown in Figure 1, comprises the following steps：
Step 1, as shown in Fig. 2 broadcast head end arranges server, public broadcasting module, the live module of phone, manager visitor
Family end module, GPRS module, the network switch, IP network pipe and TS stream multiplexer；
Step 2, as shown in Fig. 2 TS flows multiplexer to from public broadcasting module, the live module of phone, GPRS module
Code stream marker recognition is carried out with the information of Administrator Client's module, and is packaged as meeting the TS flow datas of DTMB transmission；
Step 3, as shown in figure 1, TS flow datas are via DTMB terrestrial DTV front end systems, DTMB terrestrial DTVs
Transmission system is transmitted to broadcast terminal；
Step 4, as shown in figure 4, broadcast terminal carries out signal search, verification to the voice package informatin for receiving, it is determined that broadcasting
Go out and be also off broadcast, or wait broadcast.
The public broadcasting module as described in Fig. 2-1 includes PBS module and compressed encoding module, public broadcasting electricity
Platform module includes local broadcast station, Central People's Broadcasting Station, the N number of radio station module in Traffic Announcement radio station ..., and N is less than or equal to

Family end module includes county's client 1, town studio 2, flood prevention office 3 ... client N, and N is less than or equal to 30.
As shown in Fig. 2-1, when carrying out public broadcasting, broadcast station signal at different levels is passed through MPEG1 in DTMB front ends
Condensing encoder is multiplexed into system, and each of which takes independent broadcast program bag, such as, Central People's Broadcasting Station is provincial
Broadcasting station, area level broadcasting station, broadcasting station at county level etc., general 5-10 program bag is independently broadcasted due to Zhen He villages
Period is simultaneously few, therefore Zhen He villages are designed to dynamic channel allocation, and dynamic voice bag is by the Software Coding mould in server
Block simulates what is come.The broadcast data that server system is arranged according to user, the mark and terminal address code for generating voice packet is closed
The information of connection, information volume, the control instruction of broadcast slot information are packed in the lump and voice packet Jing IP/ASI gateways transmission together
It is multiplexed in system to DTMB front ends, terminal judges to broadcast which audio pack, including broadcast time according to parsing control instruction
Volume etc..
Preferably, the GPRS module receives the note for needing to broadcast, and sends information；
Preferably, several voice channels of the server virtual, to voice channel dynamically distributes；
Such as Fig. 2-1, shown in 2-2, the live module of phone of the present invention, after telephone access system, telephone coupler
Meeting dynamically distributes, make full use of channel resource, and when dynamic telephone broadcast channel has taken, phone dials in rear system and can send language
Sound is pointed out, channel is vacated rear automatic short message and notified, when being carried out by the higher broadcasting interruption of the higher broadcasting interruption of authority
Telephone-broadcast, system informed with voice and note, after the off-the-air of higher authority, informed with note, at the same time, exhaled
The telephone number for entering carries out Number Reorganization by comparing with the information in data base, distinguishes authority and is broadcasted
Region, telephone source is carried out identity and terminal address code association, confirm, subsequent system automatically forms control instruction, whole
In individual broadcast head end, the live module of phone is connected with server, and server is by from the voice of telephone coupler, note and text
Originally the voice packets of MPEG 1 are converted to, while be identified, the instruction being associated with terminal address code is packed in the lump Jing IP/ASI
Gateway is multiplexed in system into DTMB front ends, so as to complete phone live transmission.
Such as Fig. 2-1, shown in 2-3, heretofore described note broadcasting system handling process, the short message service in server
Module (being completed by systems soft ware) is converted into voice the note data from GPRS module, the channel module pressure in Jing servers
Shorten the voice flows of MPGE 1 into, packing is identified to it, simultaneity factor can inquire about data base, according to the authority of incoming call come really
The fixed region to be played, generates information, information volume, broadcast slot information that the mark of voice packet is associated with terminal address code
Control instruction in the lump DTMB front end systems are passed to by IP/ASI gateways, terminal determines whether to broadcast by parsing control instruction
Put the voice messaging, and time and the volume of broadcasting.
Such as Fig. 2-1, shown in 2-4, heretofore described text broadcasting system handling process, the text service in server
Module is converted to the voice flows of MPGE 1 the text message sent out from Internet user end, to be sent further according to user is all
Region and user play the authority of period and user, generate information, volume that the mark of voice packet is associated with terminal address code
Information, the control instruction of broadcast slot information pass to DTMB front end systems by IP/ASI gateways in the lump, and terminal is by parsing control
Instruction processed come determine whether play the voice messaging, and play time and volume.
Such as Fig. 2-1, shown in 2-5, the server controls broadcast content, broadcast time, GSM phones are met an urgent need live, note
Turn voice and text-to-speech is broadcasted, Administrator Client's module is administered by the Internet telnet server to it
Region carries out broadcast content layout modification, and the upload of audio file and text, and manager client is according to user right
Input account and password, by carrying out identification with existing information in data base, confirm identity and close automatically with terminal address
Connection, then completes, to broadcast program, from the setting of main program, broadcast slot and volume, to set after finishing by operation interface, is
System control instruction is automatically generated and completes the generation from main program bag and mark, is then exported to DTMB front end systems by IP,
Into this DMTB Transmission system.
Broadcast terminal as described in Figure 3 is by reception antenna, silicon tuner, demodulation chip, FPGA, GPRS module, audio frequency
DAC, microprocessor and audio frequency power amplifier are constituted, broadcast terminal workflow as shown in Figure 4, and the signal from front end is via reception
Antenna is input into, and by what silicon tuner completed data intermediate frequency is downconverted to, and is input to demodulation chip, and demodulation chip is intermediate-freuqncy signal solution
TS streams are adjusted to, the detection of condition code is carried out by programmable device FPGA, and audio frequency package informatin is preserved, in detection control
Under instruction regulation and control, audio pack that the system of selecting is specified simultaneously is decompressed, and then the audio stream to separating compressed encoding enters
Row decompression gives audio frequency DAC and analogue audio frequency is restored, then gives digital power amplifier, and output promotes loudspeaker.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto,
Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its
Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
