Background technology
Existing digital camera broadcast need be used digital audio decoding device, audiomonitor and frequency divider, and existing digital camera basic functional principle is: need the film of projection to be transferred in the digital server with USB mouth or port, wait for projection; Signal need be signal part transmitting photo-signal and audio digital signals from the server to the projector, and signal must be synchronous, and the signal that comes out from projector must pass through digital audio decoding device, audiomonitor and three equipment of frequency divider and could arrive power amplifier; The final sound equipment that arrives, digital decoder is to become 5.1 or 7.1 signals to digital signal decoding, makes sound number be divided into a left side; In, the right side, ultralow; A left side, back, the back is right.Whether audiomonitor mainly is to be used for the size of signal of each passage of real-time listening, normal, and frequency divider is in order to solve the frequency division to the left, middle and right signal with figure mainly, and the EQ that can also control each passage simultaneously uses with time-delay.
Present digital camera disposal system is by demoder, audiomonitor and frequency divider; The problem that has following several aspects is used in three equipment combinations: one, the conversion of the digital and analogue signals of three equipment is too many; To bring very big influence to the tonequality of equipment; Intend receiving noise easily, signal to noise ratio (S/N ratio) and dynamic range are difficult to improve.Two, systemic interface is many, and modulus and digital-to-analogue are in continuous conversion, and sound can be partially damaged as a result, and simultaneously many a lot of signal lines must meet with into unnecessary difficulty to engineering debug.Three, the inside, a lot of at the cinema Room has many audio amplifiers to need frequency division, and need be not impaired at signal, and present demoder exists can not division function.Four, movie theatre need can be accomplished signal arrival power amplifier by three equipment now, and three equipment volume are big, heavy, and cost is high, and debugging is very inconvenient, brings detection and installation to bring difficulty to system.
Summary of the invention
The utility model technical matters to be solved provides the integrated digital camera disposal system that a kind of volume is little, signal to noise ratio (S/N ratio) is high.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of integrated digital camera disposal system; It is characterized in that comprising analog input circuit, analog to digital conversion circuit, digital input circuit, analog input regulating circuit, digital decoding treatment circuit, digital audio and video signals treatment circuit and monitoring circuit; Described analog input circuit is connected with described digital decoding treatment circuit through described analog to digital conversion circuit; Described digital input circuit is connected with described digital decoding treatment circuit; The digital decoding treatment circuit is connected with described digital audio and video signals treatment circuit; Described analog input regulating circuit is connected with described digital audio and video signals treatment circuit; Described digital audio and video signals treatment circuit is connected with described monitoring circuit; Described digital audio and video signals treatment circuit is connected with described simulation output interface through D/A converting circuit, and described analog input regulating circuit is connected with described digital audio and video signals treatment circuit through switching power circuit.
Described digital decoding treatment circuit is connected with the LCD display module.
Described digital audio and video signals treatment circuit comprises that model is first chip of TAS3108 and second chip that model is TAS3108, and described second chip is connected with the 3rd chip.
Described digital decoding treatment circuit comprises the 6th chip that model is the 3rd chip of CS8416TSSOP, four-core sheet that model is CS8416TSSOP, model is CS4350TSSOP the 5th chip and model are CS4350TSSOP; Described the 3rd chip is connected with the 5th chip, and described four-core sheet is connected with the 6th chip.
Compared with prior art, the utility model has the advantages that when playing at the cinema and can well monitor that the digital and analogue signals conversion is less, noise and signal disturb few, and signal to noise ratio (S/N ratio) and dynamic range are high, can effectively improve the tonequality of device plays.
Comparing traditional cinema needs three equipment to accomplish, and the utility model volume is little, and is in light weight, and cost is low, and debugging, detection and installation aspect are also very convenient.Multimode is set simultaneously intends interface and digital interface, can satisfy requirements such as present digital tone source and simulation, increased usable range widely, adopt digital form, reduce the decay of signal.
