The LT 443D-HD HD-SDI Unit adds the 14 format HD-SDI 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-HDB: This generator has all of the features and functions of the LT 443D-HD plus two HD-SDI black outputs.
