When s_axis_video_tvalid is asserted, no
interface signals (except the AXI4-Stream Remapper core
driving s_axis_video_tready) can change value
until the transaction completes (s_axis_video_tready, s_axis_video_tvalid, and AP_RST_N are
High on the rising edge of AP_CLK). When asserted,
s_axis_video_tvalid can only be deasserted
after a transaction is complete. You cannot retract or abort any transaction. In any
cycle following a transaction, s_axis_video_tvalid
can either be deasserted or remain asserted to initiate a new transfer
