摘要

The method involves calculating a drift (800) between a control signal (SV1) i.e. vertical synchronization signal, and another control signal i.e. horizontal synchronization signal (SHL) at an image rate of a receiving device. A number of inactive lines in an image of a video signal at a level of the receiving device is adapted according to the calculated drift, where the image contains active lines including information on pixels to be displayed by a display device i.e. screen. A display rate of the video signal is controlled by a horizontal signal at the image rate of the receiving device. Independent claims are also included for the following: (1) a device for controlling a display rate of a video signal from a video source, comprising a calculation unit (2) a communication system including a video source (3) a computer loadable program comprising a set of instructions to perform a method for controlling the display rate of a video signal issued from a video source.
