Abstract

The invention provides an annotation method, device and system. The method comprises the steps that an annotation signal sent by annotation input equipment is received, coordinate data in the annotation signal is analyzed, and a display region corresponding to the annotation signal is determined based on the coordinate data; signal processing is performed on the annotation signal according to a display strategy of an annotation of the display region; and the processed annotation signal is sent to the display region for display. Through the scheme, the instruction effect of the annotation signal can be improved.

Description

technical field [0001] The present invention relates to the technical field of terminal display, in particular to a marking method, device and system. Background technique [0002] At present, in publicity, exhibitions, military exercises, security monitoring and other application fields, it is relatively common to use large screens to display related content. Most of the screens are composed of splicing walls and have multiple display areas; It is necessary to watch the content of each signal source, and also need to mark the displayed content. [0003] The display terminal of the video splicing wall usually displays dozens or hundreds of signals at the same time. The inventor found in the research that in the prior art, when the user needs to mark based on a certain specific area, there is no solution for distinguishing the marking signal that goes beyond the specific area and enters another display area, resulting in the indication of the marking signal not effectively....
