Section 1 Operation
The BVM-1911 and BVM-201 IP are high-performance color video
monitors designed for critical evaluation of video signals in
broadcasting stations and production houses.
The BVM-1911 is the NTSC model intended for use in NTSC color
standard areas and the BVM-201 lP 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, D 1 and D2
video signals to be monitored.
The other features and operations are the same.
The Super Fine Pitch Trinitron picture tube (0.3-mm aperture grille
pitch) gives a high resolution, high contrast picture. Horizontal
resolution is more than 900 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
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 and precise convergence adjustment
The convergence can be adjusted at 15 points (for 4:3-aspect pictures)
of the screen. This system facilitates adjustment of the peripheral
areas of the screen.
