Systems and methods for measuring interest levels of audience in broadcast program and providing information based on the interest levels
First Claim
Patent Images
1. A method comprising:
- receiving a transmit signal at a receiver, the transmit signal including a program and a supplementary content associating therewith;
demodulating the transmit signal to provide a data-augmented signal;
recovering the supplementary content from the data-augmented signal at substantially the same time the program is rendered at the receiver;
determining an interest level of audience in the program; and
providing information relating to the program to an audience upon finding the interest level reaches a pre-determined level.

Abstract
A system measures interest levels of audience in a broadcast program and provides extra information based on the interest level. The system receives an AV signal of a broadcast program and supplementary content which contains broadcast program related information and a tag identifying the broadcast program. The supplementary content is combined with the AV signal to form a data-augmented signal which is subsequently modulated with a carrier signal to form a transmit signal for broadcasting to receivers. Each receiver extracts the supplementary content, computes interest levels and provides extra information based on the interest levels.

14. A system comprising:
-
a receiver for receiving a transmit signal and demodulating the same to provide a data-augmented signal, the transmit signal containing a program and a supplementary content relating thereto, the supplementary content includes a data portion for containing information and a meta-data portion having at least a tag for identifying the program; and a decoder coupled to the receiver for receiving the data-augmented signal and recovering the supplementary content therefrom at substantially the same time the program is rendered at the receiver, the decoder includes a program monitoring application for determining an interest level of audience in the program and providing information relating to the program upon finding the interest level reaches a pre-determined level. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21)
