1. A system for processing audio-video data with associated location data in a storage medium for retrieval, comprising:
- means for extracting the audio-video data in conjunction with its associated location data to produce a first output signal;
voice recognition means connected to the first output signal for automatically extracting words therefrom to produce a second output signal;
means connected tot he second output signal for creating word data of the extracted words with their associated location data; and
means connected to the word data for creating a data index of the words and their associated location data.

Abstract
A technique is disclosed for processing audio-video data in a storage medium where indexes are generated by automatically extracting and indexing words and pictures in the audio-video data with their corresponding timing or other location data. The indexes permit searching and selective retrieval of word and/or scene data in accordance with location data associated therewith.
