5.4.3. SMPTE RP168 Switching Support
The SMPTE RP168 standard defines the requirements for synchronous switching between two video sources to take place with minimal interference to the receiver. The RP168 standard has restrictions for which lines the source switching can occur.
The SDI II IP core has flexibility and does not restrict you to switch at only a particular line defined in the RP168 standard. You can perform switching at any time between different video sources if the source has similar standard and format. After switching, all the status output signals, including the rx_trs_locked, rx_frame_locked, and rx_align_locked signals, remain unchanged. You should not see any interrupts at downstream.
