Hello!

 

Picture 53 on page 138 in ADV7612 Reference Manual ( UG-216 ) has the following VBI settings mentioned:

CP_START_VBI[11:0]

CP_START_VBI_EVEN[11:0]

CP_END_VBI[11:0]

CP_END_VBI_EVEN[11:0]

 

UG-216 has no other descriptions of these VBI setting.

 

These VBI settings are mentioned also in ADV7612 SOFTWARE MANUAL, but with "_R" suffix.

They are described as "Manual value for start of VBI position of the extra blank region preceding the odd / even R field in 3D TV field alternative packing format through HDMI."

 

Please clarify if these VBI settings ( without "_R" suffix as mentioned in UG-216 ) can be used for normal 2DTV field packing format or only in 3D TV field alternative packing format through HDMI ( with "_R" suffix as mentioned in ADV7612 SOFTWARE MANUAL )?
