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.
