Patent ID: 8655147

Claim:
A content reproduction order determination system, comprising: a signal feature series extraction unit that, when separate contents are inputted, extracts from each content a signal feature series, being a series of signal features caused to correspond to positions on a time axis of the content; a mutual similarity section link generator that detects mutual similarity sections, being sections in which the signal features for different contents are similar to each other, from said signal feature series for each content, and generates information for specifying the contents to which each mutual similarity section belongs and, a position of each mutual similarity section on the time axis of each content, and a link indicative of a correspondence relation of said each mutual similarity section, as mutual similarity section link information; and a content reproduction order determination unit that detects a mutual similarity section located in a beginning part or an ending part on the time axis of the content from mutual similarity section link information, and determines a correct time-sequential reproduction order of said contents to which each mutual similarity section belongs based upon a relationship of the positions of said detected mutual similarity section and the mutual similarity section corresponding to said detected mutual similarity section on the time axis of each content that said mutual similarity section link information indicates, and outputs information of the determined correct time-sequential reproduction order of said contents as content reproduction order information.
