In particular, the
VP-725DSA
:
Offers high quality de-interlacing 3:2/2:2 pull down
2
Supports firmware upgrade via RS-232
Includes non-volatile memory that retains the last setting, after switching
the power off and then on again
Scales and zooms (to up to 400% of the original size)
Digitally reprocesses the signal to correct mastering errors, and
regenerates the video at a chosen line and pixel rate format, providing, for
example, native-resolution video for LCD, DLP and Plasma displays
Facilitates scaling of graphics resolutions to other resolutions
Incorporates a unique graphics-scaling engine with image enhancement
algorithms, which are built into the firmware
Is specifically designed to improve video quality by reducing chroma noise
Includes an OSD (on-screen display) for making the adjustments that can
be located anywhere on the screen, and can be doubled in size. The OSD
can be used to deactivate the source prompt, choose the color of the blank
screen, and choose from three seamless switching transition speeds
Consists of 5 video groups—composite video, s-Video, component video
(RGB or YPbPr), DVI-D and VGA—and each group has 4 inputs (except
for DVI which has 2 inputs). Each video input has its own corresponding
balanced stereo audio input on a terminal block connector
1 Recommended for advanced users only – non-standard settings may not be recognized by the display device
2 Accommodates the frame-rate of a converted movie (24 frames per second) to video frequencies (25 frames per second
(PAL); 30 frames per second (NTSC)
