Content reproduction control system and method and program thereof

摘要

Provided is a content reproduction control system equipped with: a signal characterizing quantity sequence extraction means that, for each content item stored in a content group storage unit that stores at least more than one content item, extracts a signal characterizing quantity sequence which is the sequence of the signal characterizing quantities associated with the content positions on the time axis; a common section group detection means that detects, as a common section group in the signal characterizing quantity sequence for each content item, a common section group for which the signal characterizing quantities for different content items are similar to each other; a content reproduction quality information collection means that, for each common section group, collects content reproduction quality information which indicates the reproduction quality of the content to which each common section of a common section group belongs; and a content reproduction control means that, when the content contained in the content group storage unit is reproduced, switches the content reproduced for the content to be reproduced for the sections included in the common section group and performs reproduction such that the reproduction quality of the content will be higher, based on the content reproduction quality information for the content to which each common section of a common section group belongs.

主权项

1. A content reproduction control system, comprising:
a content group storage that stores a plurality of contents; a signal feature series extraction unit that, for each content stored in said content group storage, extracts a signal feature series, being a series of signal features caused to correspond to positions on a time axis of the content; a common section group detector that detects common sections, being sections in which the signal features for different contents of the plurality of contents are similar to each other, groups the detected sections as a common section group based on said signal feature series for each content of the plurality of contents, and generates common section group information for specifying the content to which each common section of the common section group belongs and the position on the time axis of each common section of the common section group; a content reproduction quality information obtaining unit that, for said each common section group, obtains content reproduction quality information representing a reproduction quality of the content in each common section of the common section group based on the common section group information; and a content reproduction controller that, when reproducing a content of the plurality of contents along a time axis, which is stored in said content group storage:
selects, in the common sections of to-be-reproduced content, a common section in which a reproduction quality is the greatest out of common sections in the common section group to which the common section belongs based on the common section group information;in the common sections of the to-be-reproduced content, makes a switchover to the content corresponding to the selected common section and reproduces the content; andin sections other than the common sections of the to-be-reproduced content, reproduces the to-be-reproduced content.
