The LT 443D-SD SD-SDI Unit adds the 525/625 line format SD-SDI signal (4:2:2 component signal) output capability to the LT 443D mainframe. Various functions (e.g., ID character, simple motion pictures, embedded audio, NATURAL picture pattern*1) are provided.

*1 The NATURAL picture function is only usable when the LT 443D-70 Option is installed in the mainframe.
