Each AXI input interface has its own reset signal.
The reset signals,
s_axis_audio_aresetn are for
VIDEO_OUT (AXI4-Stream Video Interface), and
These three reset signals are active-Low. Because
the reset signal is used across multiple sub-blocks in the subsystem, keep the
system in the reset state until all the clocks are stabilized. You can use the
locked signal from the clock generation block as a reset
video_rstsignal, which you can use to reset its supporting Native Video Source processing modules.
