Clocked Video Input
January 2011 Altera Corporation
The XYZ word contains the synchronization information and the relevant bits of it's
format are shown in
Table 5–6. XYZ Word Format
For the embedded synchronization format, the vid_datavalid signal indicates a valid
BT656 or BT1120 sample as shown in
function only reads the vid_data signal when vid_datavalid is 1.
Figure 5–5. vid_datavalid Timing
The Clocked Video Input MegaCore function extracts any ancillary packets from the Y
channel during the vertical blanking. Ancillary packets are not extracted from the
horizontal blanking. The extracted packets are output via the Clocked Video Input’s
Avalon-ST output with a packet type of 13 (0xD). For information about Avalon-ST
Video ancillary data packets, refer to
Separate Synchronization Format
The separate synchronization format uses separate signals to indicate the blanking,
sync, and field information. For this format, the vid_datavalid signal behaves
slightly differently from in embedded synchronization format.
The Clocked Video Input MegaCore function only reads vid_data when
vid_datavalid is high (as in the embedded synchronization format) but it treats each
read sample as active picture data.

These bits are not inspected by the Clocked Video Input MegaCore
function.
When 1, the video is in a horizontal blanking period.
When 1, the video is in a vertical blanking period.
When 1, the video is interlaced and in field 1. When 0, the video is
either progressive or interlaced and in field 0.
