Abstract
A method for skimming digital audio and video data, wherein the video data is partitioned into video segments and the audio data has been transcribed, is comprised of the steps of selecting representative frames from each of the video segments. The representative frames are combined to form an assembled video sequence. Keywords contained in the corresponding transcribed audio data are identified and extracted. The extracted keywords are assembled into an audio track. The assembled video sequence and audio track are output together. An apparatus for carrying out the disclosed method is also disclosed.
