Abstract
A system and method summarizes multimedia stored in a compressed multimedia file partitioned into a sequence of segments, where the content of the multimedia is, for example, video signals, audio signals, text, and binary data. An associated metadata file includes index information and an importance level for each segment. The importance information is continuous over as closed interval. An importance level threshold is selected in the closed interval, and only segments of the multimedia having a particular importance level greater than the importance level threshold are reproduced. The importance level can also be determined for fixed-length windows of multiple segments, or a sliding window. Furthermore, the importance level can be weighted by a factor, such as the audio volume.
