1. A peripheral component interconnect express (PCIe) caption encoder card, comprising:
an input component configured to receive an input (serial digital interface) SDI stream;
a field programmable gate array (FPGA) in communication with the input component and configured to compile an output SDI stream with embedded closed captions;
a microcontroller unit (MCU) in communication with the FPGA, the FPGA configured to receive the input SDI stream, extract closed caption data from the input SDI stream, and send the closed caption data to the MCU;
