The audio interface to an UHD-SDI Audio (Embed) is a 32-bit AXI4-Stream slave
bus. AXI4-Stream Slave generates the handshaking signal
s_axis_tready after
receiving the streaming data (s_axis_tdata), data valid signal
(s_axis_tvalid), and channel number identification
(s_axis_tid). Note: The UHD-SDI Audio (Embed) strictly expects audio samples to be distributed as per sample
rate on the AXI4-Stream Interface. One audio sample per each channel in one period of audio
clock (48 KHz, 44.1 KHz, 32 KHz).
