User manual

3.9. Enhancement
The enhancement menu provides image enhancement functions. Note that the enhancement settings
apply to video input signals only, not computer graphics signals.
3.9.1. Sharpness
Available Settings: -50 to 50 in steps of 1
Control of the sharpening enhancement filters' levels. These are peaking filters to improve high-
frequency response. Note that setting this control too high on a signal which already has good high
frequency response will cause ringing or ghosting.
3.9.2. Detail
Available Settings: 0, 1, 2, 3
This filter provides powerful 2D image enhancement which can be used to greatly improve detail
definition and clarity without causing image ringing or ghosting. It improves both horizontal and vertical
detail. Correct setting of the detail enhance filter can make SD signals look virtually indistinguishable
from true HD. At setting 0 the filter is switched off, with setting 3 providing the highest effect.
3.9.3. Video Filters
The video filters menu provides LTI and CTI filters and TRNR and MNR noise reduction filters.
The LTI filter enhances the sharpness of the luminance component. The CTI filter enhances the
sharpness of the chrominance signal by increasing the steepness of color edges.
TRNR (Temporal Recursive Noise Reduction) and MNR (Mosquito Noise Reduction) are available for
SD input signals only. These filters reduce spatial and temporal noise and block artifacts.
3.10. System
This selection contains functions which are more applicable to system operation than to picture
adjustment.
3.10.1. User
Available Settings: USER 1, 2, 3, 4
A predefined setting stored under a user name can be selected. Several settings of the VP-793 can be
stored under a user name. Thus, different users can store their preferred VP-793 settings and recall
these profiles by picking up their user name from this menu.
Note: Using the Web interface, (any number of) settings can also be stored and restored to and from a
PC disc drive.
3.10.2. Names and Profiles
The Names and Profiles menu provides input masks to rename the generic input channels and user
names. User names and input channel names can be changed to any word with a maximum of 12 alpha
numeric characters with a value range of 0-9, A-Z and blank.
The Names and Profiles menu allows the user to store profiles under a certain user name. It also allows
to copy user profiles by loading a profile stored under one user name and saving it under another user
name. Reset Profile allows to restore default settings for the currently selected user. Note: Copying
profiles may take several minutes during which the unit cannot be controlled.
