Convenient Features

Interlace Display

BVM-E and BVM-F Series monitors offer an Interlace Display
feature for 1080i and SD inputs. This lets each BVM-E and
BVM-F monitor display these inputs as a true interlace
display. As with the Native Scan function, Interlace Display
mode offers faithful reproduction of the input signal, and
the displayed interlace fields are free from the picture
degradation that can occur as a result of typical I/P
conversion processes.

Scan Switch

The Scan Switch function allows switching between under
scan (-3%), normal scan (0%), and over scan (mask of the 5%
over scan portion in the normal scan).
Native Scan (pixel-to-pixel display)
Conventional flat-panel monitors reproduce images using
scaling and I/P conversion due to their fixed pixel counts and
progressive scanning processes. The Native Scan function
is a unique display mode that reproduces images without
changing the input signal's pixel count.
For example, when an SD signal is input, the BVM-E and BVM-F
Series monitors will reproduce the image at a picture size of
720 x 487* pixels. For SD inputs the Native Scan function also
allows the displayed image size to be doubled to 1440 x 974*
by duplicating and doubling each pixel both horizontally and
* The 2 / 9.94i signal specified by Rec. ITU-R BT.601.
HD Frame Capture
The HD Frame Capture function of the BVM-E and BVM-F
Series allow a picture frame from the 3G-SDI and HD-SDI input
to be captured and saved as a picture file on Memory Stick
media.* This picture file can be used as a reference for
various purposes; for example, as for picture-tone adjustments
between past images and for camera-framing adjustments.
* Memory Stick PRO (High-Speed) / Memory Stick PRO Duo (High-Speed)
can be used.
Aspect Correction Mode
PAL and NTSC video systems are all based on rectangular
pixels. Display of these formats on a square pixel panel
typically distorts the image. The BVM-E and BVM-F Series use
a unique process called Aspect Correction which, while still
offering native pixel performance, continues to display image
geometry correctly. This scaling technique used in BVM-E
and BVM-F Series monitors corrects horizontal distortion while
keeping the vertical pixel count correctly displayed.
