Abstract
The device for addressing a plasma panel comprising a video processing circuit (7) for processing the digital video data received, a correspondence memory (8) for transcoding these data, a video memory (9) for storing the transcoded data, the video memory being linked to column driver circuits (10) for controlling the column addressing of the plasma panel, is characterized in that the transcoded data have a greater number of bits than the digital video data received and in that the processing circuit (7) comprises means for differently coding identical values of digital video data received.The applications target plasma panel control devices.
