7.3.1. Format Detection in Clocked Video Input II

After reset, if the CVI II IP has not determined the format of the incoming video, it uses the values you specify in the Avalon-ST Video Initial/Default Control Packet section in the parameter editor.

When the IP detects a resolution, it uses the resolution to generate the Avalon streaming viideo control packets until a new resolution is detected.

When the resolution valid bit in the Status register is 1, the Active Sample Count, F0 Active Line Count, F1 Active Line Count, Total Sample Count, F0 Total Line Count, F1 Total Line Count, and Standard registers are valid and contain readable values. The interlaced bit of the Status register is also valid and you can read it.
