Abstract: A computer system in which augmentation content can be provided to a client device. A receiver is provided in a server for receiving a live television signal. A matching engine can then identify a segment of television, based on fingerprinting techniques and can determine a time delay between the start time of the segment of television and its identification. A content retrieval unit can then select augmentation content based on the identified segment of television and the time delay, and this can be output to a client device. In this way the augmentation content can be selected so that it maintains synchronization with live television.

Abstract: A computer system includes a display that displays an electronic program guide to a user. A data storage unit includes keywords related to television shows currently being broadcast. A server device is configured to retrieve real-time data related to a person of interest from the internet by monitoring messages that they generate. The server device can then identify one or more matches between the retrieved data and the stored keywords, and can output a modified electronic program guide including an indication of matching keywords. This can allow an electronic program guide to include an inference of the television show that a person of interest is likely to be watching or talking about online.
