Abstract:
For use with an audiovisual display system in which an original set of audio data and a related original set of video data can be used to generate an audiovisual display at a normal display rate, a method for enabling the apparent display rate of the audiovisual display to be varied from the normal display rate, the method comprising the steps of:defining a correspondence between the original set of audio data and the original set of video data such that the original set of audio data is synchronized with the original set of video data; determining a target display rate or rates for the audiovisual display including evaluating the audio and/or video data to automatically determine the value of the target display rate including: analyzing the original set of audio data including ascertaining the stress with which spoken portions of the audio data are uttered; and calculating the target display rate based upon the analysis of the original set of audio data including calculating the target display rate or rates based upon the relative stresses of the spoken portions of the audio data; creating a blended audio sample, wherein the blended audio sample is associated with a portion of a first audio sample and a portion of an adjacent second audio sample; creating a modified set of audio data, based upon the target display rate or rates and an evaluation of the content of the original set of audio data, that corresponds to the original set of audio data; and creating a modified set of video data, wherein the modified set of video data is associated with the blended audio sample, and wherein the modified set of video data is based upon the modified set of audio data, the correspondence between the modified set of audio data and the original set of audio data, and the correspondence between the original set of audio data and the original set of video data such that the modified set of video data is synchronized with the modified set of audio data.
