TERMINAL FOR DISPLAYING A VIDEO SIGNAL WITH STATE BASED CONTROL

摘要

Terminals (1) like television receivers for displaying video signals comprise video processors (2) for processing said video signals and controllers (6) for in response to control signals controlling said processing. These terminals (1) are provided with selectors (10) for selecting states in dependence of video signal parameters comprising signal-to-noise-ratios and/or signal-strengths. The selectors (10) comprise generators (15) for, per selected state, automatically generating said control signals defining a contrast, a sharpness, a black/blue stretch, a coring, a pre/overshoot-ratio, a peaking, a histogram, a low-noise amplification. Detectors (11) for detecting the switching on of terminals (1) and/or the selection of next television channels are used in combination with (de)activators (12) for in response to detection results (de)activating at least parts of said selectors (10), to get video signals to be displayed which are always processed optimally. The user has the option of switching said selector (10) on and off, and of overruling and getting his/her individual preferences, with a graphical display that can be disabled/enabled.
