Abstract: A method for providing a horizontal scan control signal for a TV set from a horizontal synchronization signal contained in a composite video signal, the horizontal synchronization signal containing horizontal synchronization pulses and parasitic pulses, the scan control signal being provided from an oscillating signal generated by an oscillator of a phase-locked loop receiving the horizontal synchronization signal, the oscillating signal having a frequency depending on a driving signal provided from the comparison between the horizontal synchronization signal and a binary phase signal, in which, at each parasitic pulse among successive parasitic pulses between two synchronization pulses, the driving signal is successively varied in the increasing direction or in the decreasing direction.

Abstract: In order to display moving images, an input receives a video signal transporting video images. A user interface receives commands input by a user. An input video subsystem continuously generates a first stream of video images on the basis of the input video signal. At least one volatile storage unit stores a sequence of images extracted from the first stream of images, either continuously, or in response to a “record” command given by the user. An output video subsystem generates and displays a second stream of images on the basis selectively of: the first stream of video images, the stored sequence of images, or a combination of the two, in response to an appropriate read command input by the user via the user interface.
