  • Intelligent video signal encoding utilizing regions of interest information
    Patent number: 8351513
    Abstract: Digital video content is processed for delivery over a communications channel by segmenting the digital video content into one or more regions of interest (ROI) in accordance with content signature of the video content and encoding the digital video content in accordance with the ROI segmentation and the communications channel.
    Type: Grant
    Filed: December 19, 2007
    Date of Patent: January 8, 2013
    Assignee: Allot Communications Ltd.
    Inventors: Jiangtao Gene Wen, Sujit Dey, Parag Arole, Jinwen Zan, Supriya Bhat, Andjela Illic
  • System and method for transform coding randomization
    Patent number: 7778476
    Abstract: A method and system are provided where image data is encoded in the spatial domain, and transformed in a two dimensional transform process to thereby recover a frequency domain representation of the image data. The frequency domain representation is then quantized to obtain an integer representation. The integer representation is ordered by frequency. Then, the hi-frequency coefficients are recreated and intelligently randomized at selective frequencies. This provides high quality encoded picture results, with fewer artifacts than those that would result from conventional approaches afflicted by artifacts due to loss of high frequencies.
