Input terminal is intended merely to distinguish what signal was inputted and named, when it is implemented, gating signal input terminal and high-definition signal input terminal
It is the normal signal input terminal of encoder, the two does not have substantive difference.
Further, since the corresponding audio signal of high-definition video signal is transmitted respectively, the embodiment of the present invention provides
Apparatus for processing of video signals be not related to the corresponding audio signal discussion of high-definition video signal, but due to SD vision signal
Corresponding audio signal (audio IIS) is transmitted together, by SD vision signal converter 111 AD conversion it
Afterwards, audio signal exports respectively with vision signal, and therefore, SD vision signal converter 111 is also comprising audio signal all the way
Output terminal is directly connected with encoder 131, since the idiographic flow that encoder 131 handles it is same as the prior art,
This is repeated no more.
The principle of apparatus for processing of video signals processing vision signal provided in an embodiment of the present invention is introduced below in conjunction with Fig. 2.
High-definition video signal standard is 1080P, and SD standard is 960H, in the embodiment of the present invention, is inputted in vision signal
End carries out branch process, can be divided into following two branches：First, by coupled capacitor until 4 road high-definition video signal AD turn

Clear vision signal converter 111 carries out the analog-to-digital conversion of SD vision signal.
Vision signal exports 4 groups of HD videos for meeting BT656 agreements after the conversion of high-definition video signal converter
The 4 tunnels simulation high-definition video signal of signal, respectively corresponding input, when it is implemented, high-definition video signal AD conversion can be configured
A signal output part is had a high regard for be bound with the vision signal selector channel configured in CPLD, the signal output part output after binding
High-definition video signal will encoder be transmitted to by the vision signal selector channel of binding, to bind first signal in Fig. 2
Exemplified by the BT656 high-definition video signals of output terminal output.Specific implementation can be configured to the arbitrary high definition all the way of binding the 1st~4 and regard
The signal output part of frequency signal converter is switching to possibility by above-mentioned 4 tunnel high definition of configuration/SD vision signal.
Enter back-end code device for the 2nd~4 tunnel of high-definition video signal converter output is direct-connected.
SD vision signal converter export 1 tunnel four-in-one the SD vision signal for meeting BT656 agreements, i.e., this
The clear vision signal of road sign contains the SD analog signal of 1~4 tunnel whole.High-definition video signal converter exports all the way
BT656 high-definition video signals and the SD vision signals of BT656 all the way of SD vision signal converter output access one together
Piece CPLD is for the vision signal selector channel of switching, and CPLD is connected by iic bus with controller, according to the communication protocols of formulation
CPLD can be write according to actual channel selecting by configuration order and data IIC by discussing controller, so that it is determined that CPLD is exported
Vision signal be high-definition video signal or SD vision signal, finally compiled again by the BT656 vision signals of gating
Decoded processing, subsequent processing mode is identical with the prior art, and which is not described herein again.
For example, the 1st tunnel is standard definition signal in 4 tunnel vision signals of video signal input terminal input, 2~4 tunnels are high definition letters
Number, then the SD video Buffer of the first via is opened, and vision signal selector channel is configured to allow for SD vision signal to pass through mould
Formula, the gating signal input port (in Fig. 2 exemplified by the 1st group VI mouthfuls) of encoder receive SD BT656 signals；2~4 tunnel high definitions
Signal walks direct-connected high definition BT656 passages, into the high-definition signal input port (the 2nd~4 group VI mouthfuls) of encoder.Therefore, have
When body is implemented, as long as it is standard definition signal to have 1 tunnel vision signal in 4 tunnel vision signals, vision signal selector channel can all be configured
Into permission SD vision signal by only can be just configured to when 4 tunnel vision signals of input terminal input are full high-definition signals
High-definition video signal is allowed to pass through.
When it is implemented, due to the limitation of high-definition video signal converter hardware design, each high-definition video signal AD
Converter at most can only be AD converted and export to the high-definition video signal for being no more than 4 tunnels simultaneously, and SD vision signal AD
Model that there are two types of converters, a kind of is that at most can only the SD vision signal for being no more than 4 tunnels is AD converted and be exported simultaneously,
Another the SD vision signal that is no more than 8 tunnels can be AD converted simultaneously and export (during output, the clear video of 8 road signs
Signal converter exports the signal synthesis for being often no more than 4 tunnels all the way, i.e., is synthesized for being no more than the SD vision signal on 4 tunnels
Need to synthesize two-way output when all the way, more than 4 tunnel), if therefore when it is implemented, the vision signal of front-end collection is more than 4 tunnels
But when being no more than 8 tunnel, structure shown in Fig. 3 may be employed.
As shown in figure 3, due to that may need to handle the high-definition video signal more than 4 tunnels, vision signal AD conversion list
Member can include 4 road high-definition video signal converter 112 of two panels and the clear vision signal converter 111 of a piece of 8 road sign, separately
Outside, since a piece of encoder 131 simultaneously can only compile 4 road BT656 vision signals (including standard definition signal and high-definition signal)
Code, therefore, it is necessary to two panels encoder 131, specific connection is as follows：
Unlike 4 road apparatus for processing of video signals, since the clear vision signal converter 111 of 8 road signs may output
The SD vision signal for meeting BT656 agreements of two-way synthesis (is more than 4 in the simulation SD vision signal of signal input part input
During road), therefore, video signal selector 121 needs to configure a vision signal selector channel, each vision signal selector channel
The BT656 high-definition video signals of the output of high-definition video signal converter 112 and all the way SD vision signal all the way are received respectively
The BT656 SD vision signals that converter 111 exports.It when it is implemented, can be from two high-definition video signal converters
112 signal output port respectively bind with a vision signal selector channel (such as Fig. 3 institutes respectively by one signal output port of selection
Show), two signal output ports point can also be selected from the signal output port of same high-definition video signal converter 112
It is not bound with a vision signal selector channel, the present invention does not limit this.Unbound high-definition video signal converter 112
Signal output port directly bound with the high-definition signal input port of encoder, and SD vision signal converter 111
Two signal output ports are connected respectively with a vision signal selector channel.The SD gated by vision signal selector channel regards
Frequency signal or high-definition video signal enter the gating signal input port of encoder 131, equally, when it is implemented, can be from
An input port is respectively selected to be connected to receive each regard with the output port of video signal selector 121 in two encoders 131
The SD vision signal or high-definition video signal (as shown in Figure 3) of frequency signal behavior passage output, can also be from same coding
In device 131 two input ports is selected to be connected with the output port of video signal selector 121, the present invention does not limit this
It is fixed.
Two panels encoder 131 is single with control by PCIE_Switch (PCIE adapters include multiple PCIE interfaces) respectively
The decoder 141 of member 14 connects, and the controller 142 of control unit 14 is by iic bus and video signal selector 131 (in Fig. 3
By taking CPLD as an example) connection, two video selector channels of the controller in configuration control CPLD allow SD vision signal to lead to
It crosses or high-definition video signal is allowed to pass through.
In addition, for 8 tunnel audio signals in SD vision signal, SD vision signal AD during due to 4 tunnel vision signal
41 voice datas of conjunction of converter output are transferred to encoder by IIS, and SD video AD converter during 8/16 tunnel is 8
Road, therefore the voice data by AD outputs is 8 conjunctions 1.In view of the code capacity of encoder in itself can only handle 4 tunnel high definitions
1080P, 8 tunnels are to need two panels encoder, and 16 tunnels need 4.So when handling 8/16 tunnel audio signal, 8 close 1 audio letter
It number can enter the SIO mouths of two panels encoder simultaneously, but every encoder need to only be handled 4 tunnel therein audio signal,
When it is implemented, can be realized by being pre-configured with, which is not described herein again.
Remaining connection of 8 road apparatus for processing of video signals is identical with 4 road apparatus for processing of video signals, and which is not described herein again.
For 16 road apparatus for processing of video signals, knot can be connected there are two 8 road apparatus for processing of video signals compositions
Structure is as shown in figure 4, the implementation of every one 8 road apparatus for processing of video signals may refer to the reality of above-mentioned 8 road apparatus for processing of video signals
It applies, which is not described herein again.Certainly, when implementing the present invention, 4/8/16 above-mentioned road apparatus for processing of video signals can be integrated
