Abstract

The experience of a consumer of a primary video or audio program is enriched by providing secondary and time relevant content to a secondary device, such as a laptop computer, tablet, or smart phone. Transmissions of the primary video or audio are augmented by secondary data providing links to the secondary content. The secondary data also contains data identifying the corresponding primary program and the temporal location within the primary program at which the secondary content is to be offered. Upon receipt and display of a pre-produced primary program, a device driving the primary program output device, such as a set-top-box driving a television, transmits the secondary data over a local network to the secondary device, which displays links to the secondary data, and enables the consumer to request the corresponding secondary content for display on the secondary device. Indications of secondary content may also be sent to the primary program output device to inform the consumer of the availability of secondary content.
