For example, after the programmable logic device 1421 performs the intercepting and scaling process on the received initial image data according to the self-carrying information to obtain the processed image data, the processed image data is input to the programmable logic device 1431 through the four SerDes input interfaces 14311 through the four SerDes output interfaces 14211, and when the programmable logic device 1431 successfully receives the processed image data through the four SerDes input interfaces 14311, for example, the four interconnected communication interfaces 14312 output "0" respectively, and the programmable logic device 1421 receives "0000", it can be determined that the four SerDes output interfaces 14211 are normal. When there is a situation that a certain SerDes output interface 14211 is faulty and image data cannot be transmitted, and the SerDes input interface 14311 corresponding to the faulty SerDes output interface 14211 cannot receive image data, the programmable logic device 1431 outputs a level signal through the four interconnect communication interfaces 14312, that is, the interconnect communication interface corresponding to the faulty SerDes output interface 14211 outputs "1", the remaining interconnect communication interfaces 14312 output "0", and when the programmable logic device 1421 receives the level signal, the faulty SerDes output interface 14211, that is, the faulty SerDes output interface 14211, may be determined according to the interconnect communication data interface 14212 accessed to "1", and then the SerDes output interface 14211 is reconfigured, that is, the SerDes output interface 14211 is restored to an initial state, so as to implement normal operation of the SerDes output interface 14211 again.
