INFORMATION PROCESSING DEVICE AND METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To synchronize a plurality of contents acquired through different paths.SOLUTION: A main receiving device acquires a main content to reproduce it. A sub-receiving device extracts a feature amount for voice synchronization from a voice signal acquired by collecting voice of the reproduced main content. The sub-receiving device acquires a sub-content having time synchronization relation to the main content and a feature amount for voice synchronization of the main content which is associated with the sub-content. The sub-receiving device compares the extracted feature amount for voice synchronization and the acquired feature amount for voice synchronization with each other to generate synchronization correction information for reproducing the sub-content by synchronizing it with the main content. This technique can be applied to an information processing device as well.
