  • Encoding and decoding of video signals
    Publication number: 20020136292
    Abstract: The disclosure has application for use in conjunction with a video encoding/decoding technique wherein video images are encoded using truncatable image-representative signals in bit plane form. A disclosed method includes the following steps: determining a specified number of bitplanes for the coding of an image-representative frame; and producing an encoded bitstream for the frame which has a syntax-containing portion that includes a representation of the specified number.

  • Video apparatus and method for digital video enhancement
    Publication number: 20020080878
    Abstract: A method for encoding frames of input video, including the following steps: processing the input video to produce a compressed base layer bitstream; processing the input video to produce a compressed enhancement layer bitstream; identifying a region of interest in a video frame; and enhancing the quality of the region of interest by providing additional bits for coding said region.
