Another internal switch in the VCJ selects the signals at
pins 67-69 or pins 73-75 and directs the signals to the
internal YCbCr Processing circuitry. The signals are
converted to RGB and are directed to RGB Processing
circuitry. The RGB signals are output at pins 35, 37
and 39, and directed to the CRT Drive circuitry.
DM-RGB conversion to YCbCr enables using the
enhancements available in the YCbCr Signal Process-
ing circuitry of the VCJ. For instance, the genera-
tion of a drive signal for the Scan Velocity Modula-
tion (SVM) circuitry.
Note that the DM RGB signals are also input to the
VCJ at pin 49-51. These inputs are used for OSD
insertion when the main picture source is analog. The
DM-BLK signal, from the DM Module, times the
OSD insertion into the main picture.
When the main picture source is from the DM Mod-
ule, the OSD is inserted in the main picture in the
DM Module.
Pins 45-47 are also OSD Inputs. These inputs re-
ceive OSD signals from the Convergence circuitry,
and the CBLK signal times the Convergence OSD
insertion.
