7. Clocked Video Interface IPs

The Clocked Video Interface IPs convert clocked video formats (such as BT656, BT1120, and DVI) to Avalon streaming video; and vice versa. You can configure these IP at run time using an Avalon memory-mapped target interface.

The Clocked Video Input II IP:

  • Converts clocked video formats (such as BT656, BT1120, and DVI) to Avalon streaming video.
  • 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.

The Clocked Video Output II IP:

  • Converts data from the flow controlled Avalon streaming video protocol to clocked video.
  • Formats Avalon streaming video into clocked video. Inserts horizontal and vertical blanking and generates horizontal and vertical synchronization information using the Avalon streaming video control and active picture packets.
  • Provides clock crossing capabilities to allow video formats running at different frequencies to be created from the system.
