Abstract: A caption encoder system is provided that can include a computer system and a caption encoder card. The caption encoder card can include a caption encoder module having at least one of: an input component, a field programmable gate array (FPGA), a microcontroller unit (MCU), a peripheral component interconnect express (PCIe) bridge, and a plurality of output components. The input component can be configured to receive an input SDI stream. The FPGA can be in communication with the input component and can be configured to compile an output SDI stream with embedded closed captions. The MCU can be in communication with the FPGA. The PCIe bridge can be in communication with the microcontroller unit and a plurality of universal serial bus to serial devices. The plurality of output components can be communication with the field programmable gate array.
