Description
Technical field
The present invention relates to the combination field, relate in particular to the method for control information transmission in a kind of combination and a kind of combination system.
Background technology
In current spliced display wall field, need a control device whole system is controlled and managed, therefore each display unit in the combination need be coupled together with control information transmission by certain connected mode and control device.The method of control information transmission of the prior art roughly is divided into following two kinds:
One, by serial ports combination is carried out control and management, get up by RS485, RS422 or other mode articulatings between each display unit.But this mode needs special cable connect to come control information transmission, and the baud rate of serial ports causes system communication speed low only up to 115200bps, and control efficiency is not high;
Two, by the mode of network combination is controlled and managed, each display unit and control device all are connected on the switch by netting twine to be formed local area network (LAN) and manages and control.But the shortcoming of this mode is to need complicated netting twine cabling, especially system big more, and wiring is just complicated more, and needs the planned network Communications Processor Module on each display unit hardware, has increased display unit cost and development technique difficulty.
Summary of the invention
For addressing the above problem, the present invention proposes the method and the combination system of a kind of traffic rate height and the simple control information transmission of system wiring.
The method of control information transmission in a kind of combination system, in vision signal, embed control information to finish the transmission of control information, specifically comprise: use the index signal of CTL signal, at video field signal blanking zone control information transmission as control information and vision signal.
A kind of combination system, comprise control device, at least two display units, selected display unit is as the host node display unit, except other display units of this selected display unit as from the node display unit, described host node display unit is connected with described control device;
Described host node display unit is used for the control information that receiving control device sends, and judges whether destination address sign indicating number and the address code of self in the control information be consistent, if then respond and reply response message to control device; Then control information and vision signal are carried out compoundly if not, behind the coding complex data is sent to from the node display unit; And decode after receiving complex data from the node display unit, according to the height combination of CTL signal and DE signal control information is separated with vision signal, and the control information that separates is sent to control device;
Each is described decodes after the node display unit is used for receiving the complex data of host node display unit, height combination according to CTL signal and DE signal separates vision signal with control information, judge then whether destination address sign indicating number and the address code of self in the control information be consistent, if then respond, and will respond response message and video data and carry out compoundly, complex data is sent in the host node display unit then;
Describedly control information and vision signal are carried out compound process be specially: use the index signal of CTL signal, at video field signal blanking zone control information transmission as control information and vision signal.
By above scheme as can be seen, the method and the combination system of control information transmission in the combination of the present invention system, control information is embedded in the vision signal to finish the transmission of control information, so both can simplify the wiring complexity of combination system greatly, again can be so that the same transmission rate of control information maintenance and video data, improve the traffic rate of system greatly, accelerate system response time.

Embodiment
The invention provides the method and a kind of combination system of control information transmission in a kind of combination system, can solve the complicated and low problem of traffic rate of system wiring of the prior art.Below in conjunction with accompanying drawing specific embodiments of the invention are further described.
Current video-splicing shows in the wall, great majority have the video loop cascade circuit, just each display unit in the combination can be exported to other unit with the signal source loop of self, each display unit also has a video loop input interface simultaneously, so just can make the mode of a certain road vision signal by the loop cascade be input to all display units on the loop, each unit intercepting part wherein shows, final formation strides the screen stitching image, reaches the purpose that screen is windowed and roamed demonstration of striding of vision signal.The present invention is with DVI (Digital Visual Interface, digital visual interface) video loop of form is that implementation is described, the employing closed loop connects, and the video of any one node and control data all can be by closed loop loop transfer other arbitrary nodes to the system.
Embodiment one
A kind of combination system, comprise control device, at least two display units, from a plurality of display units selected at random one and only select a display unit as the host node display unit, except other display units of this selected display unit as from the node display unit, described host node display unit is connected with described control device, direct and the control device direct communication of host node is only arranged in the whole system, when other nodes be controlled or be inquired about to control device need, all the DVI video loop that is connected with above-mentioned closed loop by host node was forwarded to other nodes.As shown in Figure 1, be that example describes with 2 row, 4 row combination systems:
The control information that host node display unit receiving control device sends judges whether destination address sign indicating number and the address code of self in the control information be consistent, if then respond and reply response message to control device; Then control information and vision signal are carried out compoundly if not, behind the coding complex data is sent to from the node display unit;
Respectively after receiving complex data the host node display unit, the node display unit decodes, height combination according to CTL signal and DE signal separates vision signal with control information, judge then whether destination address sign indicating number and the address code of self in the control information be consistent, then do not respond if not, complex data continues to transmit along the closed loop loop; If then respond, and will respond response message and video data and carry out compoundly, complex data be sent in the host node display unit then;
The host node display unit is decoded after receiving complex data from the node display unit, according to the height combination of CTL signal and DE signal control information is separated with vision signal, and the control information that separates is sent to control device.
