Configuring Dual-Serial
Link I/O on Linux Workstations
Backdraft Conform supports dual-serial link input and output connections for 4:4:4 clip I/O on Linux workstations (except for the IBM 6224). Configure the type of I/O connection (single- or dual-link serial) using the Input Connection and Output Connection boxes in the Engineering menu. See Setting Video Input and Output Engineering Menu Controls. When you select an input or output connection for clip I/O, you usually also select the colourspace conversion method using the Colourspace box on the Engineering menu. The conversion methods that appear in this box depend on the type of I/O connection used. The following table shows the colourspace conversion methods that are available for single-link and for dual-link I/O connections on Linux workstations.
| Colourspace Conversion Method | Supported for Single-Link Serial (4:2:2) I/O | Supported for Dual-Link Serial (4:4:4) I/O |
|---|---|---|
| YCbCR -> RGB | Yes | No |
| YCbCR -> RGB + Headroom | Yes | No |
| No Conversion | No | Yes |
| No Conversion + Headroom | No | Yes |
