Abstract: Method comprising a succession of image frames which each comprise a sustain phase of the display discharge regions which itself comprises the application of sustain voltage pulses VS between the electrodes of each pair crossing these regions, and, during each sustain pulse, the application of trigger voltage pulses VM to groups of discharge regions, which pulses are applied successively and not simultaneously to the various groups of discharge regions. Thanks to the application in stages of the trigger pulses during each sustain pulse, a reduction in the instantaneous current required to supply the display is obtained.

Abstract: The present invention relates to a priming method in the cells of a plasma display panel and a device implementing said method. In a plasma display panel, each cell is provided with at least two electrodes and one type of phosphor out of at least two types is associated with each of the cells to determine the color of the light emitted by the cell. Priming consists in applying a voltage greater than a threshold voltage between the electrodes of the cells. Since the threshold voltage above which electrical charges are created in the cell is different according to the type of phosphor of the cell, it is proposed according to the invention to use, to create the charges in the cells, a voltage that differs according to the type of phosphor so as to create only the electrical charges needed in the cells.

Abstract: In a signal transmission and/or storage system including a transmission stage and, after transmission and/or storage of the signals transmitted on a passband-limited information carrier which implies a processing operation for reducing the quantity of information components to be transmitted and/or stored, a receiving and/or read stage for the transmitted and/or stored signals, which arrangement for processing signals at the transmission end includes a temporal sub-sampling sub-assembly, a motion estimation sub-assembly, a recovery sub-assembly with motion compensation, a decision-taking sub-assembly, and a fall-back processing sub-assembly, with or without spatial sub-sampling. Respective signal processing arrangements provided at the receiving end correspond to these arrangements with or without the said spatial sub-sampling.

Abstract: An arrangement for encoding two dimensional information grouped in periodical information clusters, the arrangement being comprised of a variable length encoding stage, reconstruction stage, a movement estimating stage and the prediction stage. The movement estimation stage is adapted to supply from the input signals, movement information related to the movement between input signals of the same row or of opposite rows. The reconstruction stage provides a path for additional processing of the signals when the input signals provide additional information components.
