Embodiment
The embodiment of the present invention is solved and existed in the prior art for region by providing a kind of emergent intelligent broadcast system
Sex differernce, the technical problem that emergent broadcast information can not be popularized in time, and then realize pass through in regional it is each
Kind receiving terminal can receive the technique effect of emergent broadcast message.
It is above-mentioned in the prior art in the presence of for Territorial Difference in order to solve, emergent broadcast information can not be carried out timely
The technical problem of popularization, above-mentioned technical proposal is carried out in detail below in conjunction with Figure of description and specific embodiment
Explanation.
The embodiment of the present invention provides a kind of emergent intelligent broadcast system, as shown in Figure 1 and Figure 2, including：Broadcast Controller 10,
Transmission equipment 20 and intelligent receiving terminal 30；Wherein, Broadcast Controller 10 includes emergent broadcast source of sound 101 and normal broadcast sound
Source 102, source of sound selector 103, control management platform 104, broadcast modulation modulator 105, encoder 106；Under emergency conditions,
By Broadcast Controller 10 by controlling management platform 104 according to region division condition, and according to emergent broadcast frequency interleaved modulation modulator 105
With broadcast instruction control source of sound 103 selection to emergent broadcast source of sound of selector of encoder 106, will be selected by transmission equipment 20
The emergent broadcast source of sound selected is transmitted to corresponding intelligent receiving terminal 30 and played out.
In a particular embodiment, device controller is also included in Broadcast Controller 10, can be controlled under emergency conditions
Broadcast modulation modulator corresponding to emergent broadcast is opened in broadcast modulation modulator 105 corresponding to system pause normal broadcast, control
105, emergent broadcast state is switched to by normal broadcast state so as to realize, realizes emergent play.
Specifically, emergent broadcast source of sound includes telephone monitor source of sound, short message text speech sound device source of sound, emergent microphone sound
Source.That is, emergent broadcast can be carried out in several ways at the end of Broadcast Controller 10, for example, village head has a meeting in county,
When need to notify the villager in village in time when knowing an important thing, now, it is possible to by telephone monitor by this part thing
Feelings are by the form of emergent broadcast, the villager being broadcast in village.Here multiple telephone numbers can be set to telephone monitor source of sound
Mandate, be just no longer described in detail at this.For example, if village head is now inconvenient to make a phone call, then, short message text can be passed through
This speech sound device carries out emergent broadcast, and the species of reading aloud of short message text can be Chinese male voice or female voice.In the embodiment of the present invention
In the form of emergent broadcast source of sound is just no longer described in detail.
Specifically, normal broadcast source of sound includes：Local microphone source of sound, county radio programmes source, satellite reception center, save
Program source, city radio programmes source, DVD play program source.Under normal broadcast state, above-mentioned broadcast source of sound provides normal
Broadcast singal.
When switching to emergent broadcast by normal broadcast, the broadcast singal supported according to intelligent receiving terminal 30 passes through
The broadcast instruction of frequency interleaved modulation modulator 105 and encoder 106 corresponding to emergent broadcast, control source of sound selector 103 is to emergent broadcast
The selection of source of sound.Emergent broadcast can be realized to any intelligent receiving terminal 30 by realizing, so that emergent broadcast energy
It is enough widely available in time.For example the condition of a fire occurs in A areas, monitor to need to notify A areas during the condition of a fire by control management platform 104
It is loudspeaker for the intelligent terminal 30 set positioned at A areas during resident family's emergency escape, corresponding control is switched to emergent wide
Broadcast, while type is received according to loudspeaker, control the selection of emergent broadcast source of sound.Wherein, can be audio in encoder 106
Encoder and CDR encoders, are encoded to the signal source of different coding type.
In a particular embodiment, the emergent intelligent broadcast system also includes：Synthesizer 107 and multiplexer 108, its
In, synthesizer 107 is modulated to radiofrequency signal, that is, based on the source of sound of frequency modulation broadcasting by broadcast modulation corresponding to emergent broadcast
Broadcast modulation modulator 105 corresponding to device 105 or normal broadcast carries out synthesis output after modulating.Multiplexer 108 flows to TS,
Source of sound exactly to the source of sound based on digital television broadcasting and based on frequency modulation frequency band digital audio broadcasting is encoded by encoder 106
After carry out multiplexing output.Realize the output of normal broadcast signal or the output of emergent broadcast signal.
Specifically, coding controller is also included in Broadcast Controller 10, so as to enter to broadcast modulation modulator and encoder
Row management and control.The coding controller can complete RDS/SCA/ASI data encodings, and output control data possess RDS/SCA/
The diversified forms such as ASI, FM modulators, MPEG multiplexers, the input of CDR multiplexers are directly used in, realize the cross-platform compatibility of system
Control.Therefore, above-mentioned multiplexer 108 includes MPEG multiplexers and CDR multiplexers.It is to Polymera TS streams or multiple single-unit mesh
TS stream multiple connections are that a Polymera TS comprising these content code streams flows.Corresponding above-mentioned encoder 106, specifically, CDR multiplexings
Device is that the signal of CDR encoders coding is multiplexed, and MPEG multiplexers are that the signal of audio coder coding is multiplexed.
Wherein, the signal for output being exported by synthesizer 107 is used for frequency modulation broadcasting, and the signal exported by MPEG multiplexers is used for DTV
Broadcast, the signal exported by CDR multiplexers are used for frequency modulation frequency band digital audio broadcasting.It is achieved thereby that a variety of broadcast singals are general
Type.
Transmission equipment after either multiplexer 108 is synthesized or is multiplexed to broadcast singal, is connected to by synthesizer 107
20 are transmitted, and here, transmission equipment specifically includes：Power amplifier, optical sender, photoreceiver, wireless router, specifically
Ground, can be by cable network or wireless network, and the form that more either cable network and wireless network combine is transmitted
Broadcast singal reaches intelligent receiving terminal 30.
Specifically, intelligent receiving terminal 30 includes demodulator and loudspeaker or demodulator and display, e.g. intelligence
Energy audio amplifier or intelligent broadcast loudspeaker, corresponding emergent broadcast signal can be received.
Although preferred embodiments of the present invention have been described, but those skilled in the art once know basic creation
Property concept, then can make other change and modification to these embodiments.So appended claims be intended to be construed to include it is excellent
Select embodiment and fall into having altered and changing for the scope of the invention.
Obviously, those skilled in the art can carry out the essence of various changes and modification without departing from the present invention to the present invention
God and scope.So, if these modifications and variations of the present invention belong to the scope of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to comprising including these changes and modification.
