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.

LT 443D-SDB: This generator has all of the features and functions of the LT 443D-SD plus two SD-SDI black outputs.
