  • Local Flextream over internet protocol
    Patent number: 8599931
    Abstract: The invention relates to the field of digital television. More exactly, the invention deals with video compression equipments inside television head-ends, which comprise encoders grouped in encoding pools for statistical multiplexing. The invention also concerns of a method for driving individual output bitrates for encoders gathered in such encoding pool.
    Type: Grant

  • Device and process for estimating noise level, noise reduction system and coding system comprising such a device
    Patent number: 7515638
    Abstract: The present invention relates to a device and a process for estimating the noise level of video images before coding. The device comprises in particular means of storage of at least one input image, a blockwise motion estimation module, designed to produce, blockwise, first quantities representative of motion-compensated image variations, on the basis of a current input image and of at least one input image stored previously in the said means of storage, means of estimation of a global noise level for each image as a function of at least certain of the said quantities representative of motion-compensated image variations, The said device comprises means of estimation of a local noise level for each block of the image as a function of second quantities representative of motion-compensated image variations and of the global noise level.
