System and method for transmitting optical fiber video images

Abstract

The invention provides a system for transmitting optical fiber video images. The system comprises a low voltage differential signaling (LVDS) video data input module, an LVDS video data output module, a video graphic array (VGA) video data output module, a core processor FPGA, a programmable read-only memory (PROM) used for loading program for the FPGA, an LVDS clock input module, an optical fiber transceiver and a power supply system. The VDS video data input module, the LVDS video data output module, the VGA video data output module, the PROM used for loading program for the FPGA, the LVDS clock input module and the optical fiber transceiver are all connected with the core processor FPGA, and the power supply system supplies power to the modules. A method for transmitting the images by adopting the system for transmitting the video images is further provided. The system and the method have the advantages of being changeable if adopting the FPGA to achieve the protocol, saving the troubles for purchasing a plurality of chips and saving cost. ROCKETIO single channel rate of the FPGA supports 6.5Gbps and meets requirements for most rates, and the bandwidth reaching up to kilomega of the optical fiber channel brings possibility to audio / video high-capacity data.

Description

technical field [0001] The invention relates to transmission technology, in particular to an optical fiber video image transmission system and transmission method. Background technique [0002] A communication protocol based on FC-AV is commonly used in existing video transmission systems. The image resolution of the dedicated FC-AV communication protocol chip is specific, even if there is a change within a certain range, and FC-AV The communication protocol of FC-AV has many branches, so the communication protocol of FC-AV is changeable. However, the dedicated FC-AV communication protocol chips are almost all from foreign countries, so it is difficult to purchase high-speed dedicated chips and the cost is high. [0003] Modern digital video image transmission methods are as follows: [0004] 1. Digital parallel bus; [0005] 2. Serial bus: LVDS (Low-Voltage Differential Signaling low-voltage differential signal), DVI (Digital Visual Interface, digital video interface), H...
