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. In generating the delivery schedule, the preprocessor ensures that each object of the presentation and its associated presentation command arrive at the presentation processor no later than its presentation time; objects and commands which are delivered to the presentation processor can be accommodated at the memory of the presentation processor; and those objects to be presented immediately in response to a customer's selection of an interactive feature are received at the presentation processor prior to their earliest presentation times. This delivery schedule contains delivery commands which are executed by the delivery processor for transmitting objects of the presentation and their associated presentation commands to the presentation processor, which executes the presentation commands and presents the objects to its corresponding customer.

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. Lastly, my apparatus and method entail generating a variance ratio based on the first and second intensity variance arrays, determining a block variance loss based on the variance ratio, and generating the subjective quality rating indicated by the impairment level which is based on the variance loss.
