The Clocked Video Interface IP cores convert clocked video formats (such as BT656, BT1120, and DVI) to Avalon-ST Video; and vice versa. You can configure these IP cores at run time using an Avalon-MM slave interface.

Table 4-1: Clocked Video Interface IP Cores

	IP Cores		Feature
CVI IP cores			• Converts clocked video formats (such as BT656, BT1120,
•	Clocked Video Input		and DVI) to Avalon-ST Video.
• Clocked Video Input II			• Provides clock crossing capabilities to allow video
			formats running at different frequencies to enter the
			system.
			• Strips incoming clocked video of horizontal and vertical
			blanking, leaving only active picture data.
CVO IP cores			• Converts data from the flow controlled Avalon-ST Video
•	Clocked Video Output		protocol to clocked video.
• Clocked Video Output II			• Formats Avalon-ST Video into clocked video by
			inserting horizontal and vertical blanking and generating
			horizontal and vertical synchronization information
			using the Avalon-ST Video control and active picture
			packets.
			• Provides clock crossing capabilities to allow video
			formats running at different frequencies to be created
			from the system.

Control Port

To configure a clocked video IP core using an Avalon-MM slave interface, turn on Use control port in the parameter editor.

Initially, the IP core is disabled and does not output any data or video. However, the Clocked Video Input IP cores still detect the format of the clocked video input and raises interrupts; and the Clocked Video
