摘要:
A portion 301-303 of a content stream 300 for a program is automatically summarized using a summarization function mapping the program to a new segment space and depending upon whether the content portion is a beginning, intermediate, or ending portion of the content stream 300. The summary generated also depends on the duration of the summarized segment, the selected length of the summary, program type (live broadcast or replay from storage), genre, and personalized user profile information. A full summary of the entire program, if available, may be employed in generating the content portion summary. Automatic video content analysis, together with analysis of subtitles or ancillary information sources, if either is available, may be employed to generate the summary.
