A new transmission scheme is given for cutting costs, transmitting signals as much as possible and improving performance. This paper begins with a discussion of the characteristics of FPGA, A/D and D/A converter and HP1032/1034, followed by under the premise without increasing transmission bandwidth, five video signals and sixty data signals are transmitted simultaneously. A new method to solve this problem is presented, which is simple and practicable. Specific method is that each one video signal and twelve data signals are attached by FPGA, which is equivalent to using the bandwidth of one video signal without compression, completing one video signal and twelve low-speed data signals composite transmission.
