Abstract
The invention discloses a display for pushing and overlapping display contents through a wired Ethernet, and relates to a display for pushing and overlapping the displayed contents through the wired Ethernet, solving the problems of complex realization and higher cost that the mode of displaying and overlapping the contents by the traditional display seriously depends on a signal source device operation system and software. A wired Ethernet interface of the display for pushing and overlapping the display contents through the wired Ethernet is used for sending a digital signal sent by an upper computer to the digital signal input end of a wired Ethernet communication module, the signal output end of the wired Ethernet communication module is connected with the digital signal input end of a command analysis control module, the control signal output end of the command analysis control module is connected with the control signal control end of an OSD (On Screen Display) overlapping display module; the display signal output end of the OSD overlapping display module is connected with the control signal input end of a display control circuit; and the display signal output end of the display control circuit is connected with the display signal input end of a display. The display is used for displaying and overlapping the contents.
Description
Technical field
The present invention relates to a kind of display, be specifically related to push by wired ethernet the display of Overlapping display content.
Background technology
The display source signal that existing all displays uses all is directly to transmit the mode of picture signal by RGB, VGA, DVI, HDMI etc., and can only show at one time the content of a signal source picture.The content that shows on the screen will depend on the display output of the equipment such as computer, video player.Play the word message that is superimposed upon on the existing picture or the whole demand such as picture color filter that changes if having in the normal display frame of display, usually need to depend on computer that signal source is provided, video processing equipment, display superimpose device etc.This mode depends critically upon operating system and the software of signal source equipment, implements very complicated and cost is high.
Summary of the invention
The present invention depends critically upon operating system and the software of signal source equipment for the mode that solves the demonstration stack content that has display now, implement problem very complicated and that cost is high, thereby proposed to push by wired ethernet the display of Overlapping display content.
Push the display of Overlapping display content by wired ethernet, it comprises wired Ethernet interface, wired ethernet communication module, instruction parsing control module, OSD Overlapping display module, display control circuit and display,
Described wired ethernet interface will receive the digital signal input end that digital signal that host computer sends is sent to the wired ethernet communication module,
The digital signal input end that the digital signal output end and instruction of wired ethernet communication module is resolved control module connects;
The control signal output that control module is resolved in instruction is connected with the control signal input of OSD Overlapping display module;
The display output of OSD Overlapping display module is connected with the control signal input of display control circuit;
The display output of display control circuit is connected with the display input of display.
The present invention transmits literal and control signal by wired ethernet, the display that directly stack is intercutted Word message, changed the specific region color or Show Picture at ad-hoc location under existing normal demonstration.Having realized content that stack is intercutted can be fix, float, the display modes such as rolling or flicker.This implementation does not need to consider the complicated current conditions such as device type, operating system, the software and hardware of image signal source configure, whether signal source works, and cost is lower.
Description of drawings
Fig. 1 is electrical structure schematic diagram of the present invention.
Embodiment
Embodiment one, specify present embodiment in conjunction with Fig. 1, the described display that pushes the Overlapping display content by wired ethernet of present embodiment, it comprises wired Ethernet interface 1, wired ethernet communication module 2, instruction parsing control module 3, OSD Overlapping display module 4, display control circuit 5 and display 6
Described wired ethernet interface 1 is sent to the digital signal that receives the digital signal input end of wired ethernet communication module 2,
The digital signal input end that the digital signal output end and instruction of wired ethernet communication module 2 is resolved control module 3 connects;
The control signal output that control module 3 is resolved in instruction is connected with the control signal input of OSD Overlapping display module 4;
The display output of OSD Overlapping display module 4 is connected with the control signal input of display control circuit 5;
The display output of display control circuit 5 is connected with the display input of display 6.
The ability mode can have word message and icon content Overlapping display on the picture now by network push at any time in the picture of the normal display image signals of display source, and can remind the beholder to note by change or the flicker of picture color.This implementation does not need to consider the complicated current conditions such as device type, operating system, the software and hardware of image signal source configure, whether signal source works.Realization and deployment are very easy.
Present embodiment increases the wired ethernet interface at display casing when making display, increase the circuit of wired ethernet communication module, instruction parsing control module and OSD Overlapping display module at circuit.By the electronic circuit winding displacement these modular circuits are integrated together.
The described difference that pushes the display of Overlapping display content by wired ethernet of embodiment two, present embodiment and embodiment one is, the digital signal that described wired ethernet interface 1 receives comprises word content and control command.
The described difference that pushes the display of Overlapping display content by wired ethernet of embodiment three, present embodiment and embodiment one is, the control signal that control module 3 outputs are resolved in described instruction comprises the control signal of the word message that superposes, the control signal of overlay drafting color and the control signal of superimposed image.
The described difference that pushes the display of Overlapping display content by wired ethernet of embodiment four, present embodiment and embodiment one is, when OSD Overlapping display module 4 was received the control signal of the stack word message that instruction parsing control module 3 is exported, OSD Overlapping display module 4 was with the control signal of output character message with the mode display text content of rolling or flicker;
When OSD Overlapping display module 4 is received the control signal of the overlay drafting color that instruction parsing control module 3 is exported, OSD Overlapping display module 4 will be exported the control signal that shows the arbitrary size zone in the optional position of current screen, and the control signal in described zone comprises with random color carries out the control signal of the transparent region that filter processes and the Region control signal of flicker;
When OSD Overlapping display module 4 is received the control signal of the superimposed image that instruction parsing control module 3 is exported, OSD Overlapping display module 4 will be exported the control signal of predefined image, and the control signal of described image is image, picture and icon are superimposed upon current screen with transparency, size and the position of appointment control signal.
