I'm trying to develop an imaging system with the TR4 development kit. My imaging sensor has an analog output and I'm digitizing it using a 14 bit ADC. The ADC produces serial LVDS data and I'm deseri...

CVI is not supposed to have raw pixel data stream at its input.

CVI converts clocked video formats (such as BT656, BT1120, and DVI) to Avalon-ST Video.

formats:

■ Video with synchronization information embedded in the data (in BT656 or

BT1120 format)

■ Video with separate synchronization (H sync, Vsync) signals
