  • Apparatus and method for predicting subjective quality of compressed images
    Patent number: 5790717
    Abstract: An apparatus and method are described for predicting a subjective quality rating associated with a reference image compressed at a given level. My apparatus includes components for, and my method includes steps of, storing a digitized color image representing a reference image in memory and compressing at a given level and decompressing the reference image to produce a processed image. My apparatus and method also entail converting the reference image and the processed image each to a grayscale image and dividing each grayscale image into an array of blocks. My apparatus and method further entail generating a first intensity variance array corresponding to the array of blocks of the grayscale reference image and a second intensity variance array corresponding to the array of blocks of the grayscale processed image.

  • Method for preprocessing multimedia presentations to generate a delivery schedule
    Patent number: 5706486
    Abstract: An apparatus and method for preprocessing multimedia presentations to be delivered to customers such that delays due to interactive response time is virtually eliminated is described. The preprocessor receives as inputs an original multimedia presentation and parameters characterizing other system components, which parameters include the round trip latency between a delivery processor and a presentation processor, and generates a preprocessed multimedia presentation including a delivery schedule in the form of a labelled, directed graph.

  • Apparatus for determining round trip latency delay in system for preprocessing and delivering multimedia presentations
    Patent number: 5696948
    Abstract: A system and method for preprocessing and delivering multimedia presentations to customers such that delays due to interactive response time is virtually eliminated include a preprocessor, mass storage, a delivery processor, a distribution network, and a plurality of presentation processors. The preprocessor receives as inputs an original multimedia presentation and parameters characterizing other system components, which parameters include the round trip latency between the delivery processor and a presentation processor, and generates a preprocessed multimedia presentation including a delivery schedule in the form of a labelled, directed graph.
