Abstract
The invention provides a method for realizing binding of a display screen control system and computers through feature codes, and solves the technical problem that safety of the prior art is low. The method includes: (1) presetting binding information, marking each playing computer with one or multiple feature codes, identifying the feature codes through set software of the playing computers, and sending the feature codes to the display screen control system; (2) running binding connection, when the set software of the current playing computer packs the feature codes of the computer and adds the feature code packet into image data, sending the to the display screen control system. By the method, safety performance of system playing is improved, and the problem about playing safety in the field of the current LED display screen control system is solved.
Description
Technical field
The present invention relates to a kind of method that realizes display screen control system and computer binding by condition code.
Background technology
Existing LED display control system is in the relevant issues about broadcasting security, and mainly and control system signal post real-time by playout software reaches.The defect of prior art is, if once communication is broken down, eject miscue frame, and also may show in LED display at broadcast window.This technology can only solve the problem that control system is play bullet mistake of changing, and changes the securities such as player, replacing broadcasting computer all cannot guarantee for user.Prior art does not well accomplish broadcasting computer and control system ideally to bind, illegal molecule only need be changed with the computer of illegal video source and just can play-over, control system end does not carry out intercept process completely, gives the very large problem of having brought safely of playing.
Summary of the invention
The invention provides a kind of method that realizes display screen control system and computer binding by condition code, be intended to solve the not high technical matters of prior art security.
For realizing above goal of the invention, the present invention proposes following solution.
A method that realizes display screen control system and computer binding by condition code, comprising:
(1) preset binding information
Each is play computer and has all identified one or more condition codes, plays the software of computer setting and identifies this condition code, and condition code is sent to display screen control system;
For broadcasting computer and the display screen control system of coupling, display screen control system storage is set with and plays the identical or unique characteristic of correspondence code of computer;
(2) operation binding connects
The software of current broadcasting computer setting adds the described condition code packing of self in view data to, sends to display screen control system;
The view data that current broadcasting computer is sent, display screen control system first decompress(ion) obtains the condition code of current computer; Then, display screen control system mates this condition code with the condition code of self setting, if the match is successful completely, authorize display screen control system playing image content, otherwise, carry out data interception, guarantee the acceptance of the shown screen control system of invalid data stream.
Above-mentioned condition code can identify two conventionally, when two condition codes are all identical or unique corresponding with broadcasting computer, represents coupling completely.
The transmission interface of above-mentioned view data can be DVI, HDMI, SDI, DP interface etc.
Above-mentioned LED display control system can be both asynchronous display screen control system, can be also simultaneous display screen control system.
The present invention has the following advantages:
The scheme that the present invention proposes is by playing computer, condition code being set, built-in feature code in the view data sending to control system, and control system itself also presets the condition code as match information; Before control system displaying video content, by simple match information, judge, determine whether normal play.This mode neither can affect image displaying quality and ideally enciphered data is embedded in image data stream again, for disabled user, change computer or control system, at LED display control system end, can identify and make the processing of tackling, having promoted the security performance of system plays.
Change computer and play illegal video source, controller will not be accepted, and well solve the problem that security is play in current LED display control system field.
Accompanying drawing explanation
Fig. 1 is binding method process flow diagram of the present invention.
Embodiment
As shown in Figure 1, the method that realizes display screen control system and computer binding by condition code of the present invention, comprising:
(1) preset binding information
Each is play computer and has all identified one or more condition codes, plays the software of computer setting and identifies this condition code, and condition code is sent to display screen control system;
For broadcasting computer and the display screen control system of coupling, display screen control system storage is set with and plays the identical or unique characteristic of correspondence code (key) of computer;
(2) operation binding connects
The software of current broadcasting computer setting adds the described condition code packing of self in view data to;
The view data that current broadcasting computer is sent, display screen control system first decompress(ion) obtains the condition code (key K eyl) of current computer; Then, display screen control system mates this condition code with the condition code (key K ey2) of self setting, if the match is successful completely, authorize display screen control system playing image content, otherwise, carry out data interception, guarantee the acceptance of the shown screen control system of invalid data stream.
For playing computer, can identify two condition codes, when two condition codes are all identical or unique corresponding with broadcasting computer, represent coupling completely; Otherwise think and do not mate.Like this, can more strictly guarantee the acceptance of the shown screen control system of invalid data stream.
Claims (3)
1. by condition code, realize a method for display screen control system and computer binding, comprising:
(1) preset binding information
Each is play computer and has all identified one or more condition codes, plays the software of computer setting and identifies this condition code, and condition code is sent to display screen control system;
For broadcasting computer and the display screen control system of coupling, display screen control system storage is set with and plays the identical or unique characteristic of correspondence code of computer;
(2) operation binding connects
The software of current broadcasting computer setting adds the described condition code packing of self in view data to, sends to display screen control system;
The view data that current broadcasting computer is sent, display screen control system first decompress(ion) obtains the condition code of current computer; Then, display screen control system mates this condition code with the condition code of self setting, if the match is successful completely, authorize display screen control system playing image content, otherwise, carry out data interception, guarantee the acceptance of the shown screen control system of invalid data stream.
2. the method that realizes display screen control system and computer binding by condition code according to claim 1, is characterized in that: described condition code has two, when two condition codes are all identical or unique corresponding with broadcasting computer, represents coupling completely.
3. the method that realizes display screen control system and computer binding by condition code according to claim 2, is characterized in that: the transmission interface of described view data is DVI interface, HDMI interface, SDI interface or DP interface.
