3G-SDI Level

Set 3G SDI output level

The 3G‑SDI output level is applicable only to 1080p video outputs, either as a standalone HD service or as part of a quad‑link 3G‑SDI 4K service.

• Level A maps the SMPTE ST 274 format directly to a 3 Gb/s serial digital interface.
• Level B Dual-Link splits the 1080p image into SMPTE ST 372 dual‑link streams and conveys them within a 3 Gb/s serial digital interface.

When 3G‑SDI Level B Dual Link is selected and the video format is 1080p or 2160p, ancillary data is inserted into the specified line number (n) of each link. For example, if Line 9 is selected for VITC, the data is inserted into line 9 of Link 1 and line 572 of Link 2.
