1-1-1. Features
The BVM-1916 and BVM-2016P are high-performance color video
monitors designed for critical evaluation of video signals in
broadcasting stations and production houses.
The BVM-1916 is the NTSC model intended for use in NTSC color
standard areas and the BVM-2016P is the PAL model for the PAL
color standard areas. By using optional plug-in type decoder boards,
both models permit any of the NTSC, PAL, SECAM, DI and 02
video signals to be monitored.
The other features and operations are the same.
High-resolution picture
The Fine Pitch Trinitron picture tube (0.4-mm aperture grille pitch)
gives a high resolution, high contrast picture. Horizontal resolution is
more than 600 TV lines at the center of the picture.
Stabilized color temperature
The incorporated beam control circuit maintains the color temperature
constant for a long period of time.
Picture aspect selection
In addition to the conventional 4:3 aspect, the 16:9 aspect can be
selected for monitoring the increasing number of wide-screen
programs.
Split screen for precise picture confirmation
The lower half of the picture can be displayed in monochrome mode
while the upper half is displayed in color mode. This facilitates
confirmation of the luminance and chrominance channels, evaluation
of the noise in the chrominance or luminance channel, etc.
Blue-only mode for precise evaluation of noise components
In blue-only mode, an apparent monochrome display is obtained with
all three control grids driven with a blue signal. This facilitates color
saturation and phase adjustments and observation of VTR noise.
Easy-to-use menu operations
The essential parameters to be preset for video monitoring can be
easily set by selecting menu options displayed on the screen.

The BVM-1916 comes from the factory with the BT (NTSC comb
adaptor) and BC (NTSC adaptor) boards installed in compartments B4
and B5.
The BVM-2016P comes from the factory with the BD (PAL adaptor)
boards installed in compartment BS.
Note that the combinations of boards are limited by the allowable
board assignments, as shown in the table on the next page.
Add the desired boards or replace the supplied BT, BC or BD board
with optional boards, referring to the table on the next page.

• The compartments other than B 1 through B5 _arereserved for the
supplied BA, BG, BH, BI and BJ boards. Be sure to use these
boards in the respective compartments having the same names.
• Do not leave compartment BS empty. Be sure to insert one of the
boards specified in the table on the next page. If no board is
inserted, the luminance/chrominance or luminance channel will not
be activated in composite signal mode.
