 * @brief   Receives time-stamped {Downscaled RAW Video, Compressed Video, Raw EXG, Compressed EXG, Compressed Audio)
 *          and sends them to tramission Card (exptected to be via HSMC)
 *
 * This module receives three components of SmartEEG data.
 * 1- Time-stamped downscaled RAW (for live privew) and Compressed Video from the Video coder via AvalonST sinks.
 * 2- Time stamped compressed Audio via AvalonST sink
 * 3- Time stamped RAW and Compressed EXG data via AvalonST sinks
 * It transmits these data channels to transmitter card (ARM-based CycloneV FPGA SocKit board connected via HSMC)
