SDI RX Asserts Active Picture Interval Timing Signal Earlier When Receiving 3G-SDI Level B Video Data - SDI RX Asserts Active Picture Interval Timing Signal Earlier When Receiving 3G-SDI Level B Video Data Description SDI RX asserts the active picture interval timing ( rx_ap ) signal one clock cycle earlier. The first data received when the rx_ap signal asserts is not an active picture data. However, the data that come after that are all valid until the rx_ap signal deasserts. If you are relying on the rx_ap signal to process your video data, the data produced on the first cycle will be incorrect. Resolution There is no workaround for this issue. This issue will be fixed in a future version of the SDI IP core.
