  • Method and device of alignment of a video image with an edge of a display screen
    Patent number: 7034817
    Abstract: The aligning a video image with an edge of a display screen, the video image being displayed by a scanning of lines of the display screen by at least one electron beam modulated by a modulation signal, including, for each scanned line of the screen, storing successive digital video data in a storage device; detecting the end of the scanning of the line preceding the scanned line; initiating a delay upon detection of the end of the scanning of the line preceding the scanned line; starting the reading, from the storage device, of the successive digital video data stored at the end of the delay; and providing the modulation signal based on the read successive digital video data.

  • Television image format non-linear conversion device
    Patent number: 5943098
    Abstract: The present invention relates to a device for converting a television image format including two memories for storing image lines, alternatively switched in the read and write mode, and a control circuit issuing to these memories a first write frequency and a second read frequency, the control circuit including programmable means for generating said frequencies controlled by a horizontal synchronization signal, the read frequency being programmed to follow a predefined variation law having a period corresponding to the duration of one scanning line.

  • Circuit for processing asynchronous signals having periodic synchronization bursts
    Patent number: 5933458
    Abstract: A circuit for restoring bits transmitted by an asynchronous signal includes a first comparator for comparing the level of the asynchronous signal with a first threshold adjusted as a function of the output of the first comparator during synchronization bursts of the asynchronous signal, and at least a second comparator for comparing the level of the asynchronous signal with a second threshold correlated to the first threshold.
