Moreover it is evident that the layout of guidance panel of the present utility model can be changed as required, however it is not limited to Fig. 2
Shown form.Such as, power interface 16 can be not provided with, in this guidance panel, can being arranged at bottom or the side of housing.
Fig. 3 is the circuit theory schematic diagram of the present embodiment, and the Core Feature of the present embodiment is to be completed by DSP, this processor
Possess 4 road HD video inputs, 1 road HD video output, 1 road audio frequency input and output, 4 tunnel high definitions encode, 1 four picture closes
The ability grown up to be a useful person.Build on the basis of this DSP 4 road high-definition cameras gather (wherein the 4th photographic head inputs multiplexing with evidence), 1
Road omnidirectional audio gathers and the peripheral circuit such as NE, battery unit, can realize audio-video collection, picture splicing, figure
As functions such as transmission.
See Fig. 3, the image acquisition units of this utility model video camera by the first photographic head, second camera, the 3rd take the photograph
As the video information of head and the 4th camera collection is input to DSP by first, second, third and fourth input interface respectively
In, or, the data in high-definition multimedia input port it is input in DSP by the 4th interface, wherein at the 4th photographic head
Having a contactor with connecting after high-definition multimedia input port, this contactor controls the 4th photographic head and the many matchmakers of high definition
The input of body information.The audio frequency collected in omnidirectional microphone is input in DSP by sound collection unit.DSP will be by first,
Two, the video of the third and fourth input interface input is respectively delivered to the seven, the eight, the 9th and the tenth output interface, and will
The picture splicing of these videos is a road video pictures, then this road video pictures is transported to the synthesis interface six of DSP.
As it is shown on figure 3, the road video being input to synthesize interface six both can be exported by NE, also after encoded
Just can be able to export after the first output interface is the most encoded.In the DSP of diagram, there are four addressable ports, the i.e. the 3rd,
Four, the 5th and the 6th output interface, say, that this DSP has four coding passes.
When being input to synthesize a road video of interface six and/or pass through net after the audio frequency needs of mike input are encoded
During the output of network unit, this road video can enter through at least one in the three, the four, the 5th and the 6th output interface and compile
Code passage, i.e. this road video can export merely through a coding pass encodes, it is also possible to is divided into through multiple volumes
Code passage encodes and exports.And, the audio-frequency information inputted through mike both can be through identical together with this road video
Output interface carried out encoding by identical coding pass and export together, it is also possible to connect through different output from this road video
Mouth is carried out encoding by different coding passes and exports together.
On the other hand, Dang Gai mono-road video and/or through mike input audio frequency need not encoded just can export time,
This road video and/or the audio frequency inputted through mike are just transmitted directly to the first output interface and export as high-definition multimedia.
This way of output has expanded the way of output of multimedia messages, makes this video camera be not required to be only limitted to by network output letter
Breath.Additionally, special instruction, for through the 4th input interface input high-definition multimedia information, both can with by camera collection
Video be a road video through picture splicing the most as previously mentioned, export again after encoded channel coding, it is also possible to Jing Guo
One output interface exports as high-definition multimedia.
As it is shown on figure 3, the circuit theory diagrams of video camera of the present utility model also include NE, this NE example
As LAN (LAN) or WIFI can be utilized to transmit data.The audiovisual digital signal exported through this DSP is transferred to network list
Unit, then it is transferred to external equipment through NE, such as display screen, computer etc..And, external equipment also through NE to
The instruction of camera transmissions digital signal of the present utility model, information.Whole equipment is by internal signal transmission, caching audio frequency and video
While information, it is achieved the real-time operation to described video camera.
Multi-channel video is spliced into a road video through picture splicing by video camera of the present utility model, greatly reduces data
Shared space.And, the most encoded compression of audio, video data of this utility model video camera, beneficially network transmission, institute
Also being a kind of novel web camera with video camera of the present utility model, the viewer of far-end is not required to use any professional software,
As long as the web browser of standard (such as Microsoft IE or Netscape) can monitor the image of this video camera.Additionally, this
Utility model video camera both can export through network, it is also possible to the local audio, video data through wired output un-encoded, thus
Very easy to use, the demand of different occasion can be met.
Fig. 4 is scene application schematic diagram of the present utility model, and this utility model can be used in case trial, as Fig. 4 illustrates
Supported whole housing by spider or other support shown in property, turn on the power switch, enter duty.Of the present utility model
Four photographic head connect actuator, and staff can manually regulate angle and the side of each photographic head respectively by actuator
Position.Alternatively, it is also possible to controlled the focal length of photographic head respectively by the control unit of DSP or the built-in control chip of NE
With acquisition parameters such as image pickup scopes.Four photographic head of the present utility model can auto-focusing, shooting record four angles video
Information, is respectively directed to tribunal, plaintiff, defendant's seat, evidence (or visitors seats), also can record at evidence or this direction of visitors seats
Testimony of witnesses information processed.Clerk's computer is not required to special hardware support, and user can independently be equipped with, and only need to install clerk's pipe
Reason software, can realize management and recording function.When this utility model runs, power source internal has lithium battery to be available for for a long time to use,
Whole equipment is connected with external wireless cable, and audio/video information can carry out wired or wireless messages number by NE
According to controlling and transmission.
In court's trial is applied, this utility model has the advantage that
By multidirectional image collection, sound collection, picture splicing, audio/video coding, being wirelessly transferred, battery etc. carries out one
Optimal design, formation product is highly integrated, the feature of perfect in shape and function；
