Abstract:
Methods, devices, systems and computer program products facilitate accessing metadata associated with a primary audio visual content. Upon reception of a primary content, one or more watermark messages are extracted from the primary content obtain a server code and an interval code. A query to a metadata server is initiated based on the information obtained from the extracted watermark messages. In response to the query, service recovery information is received that includes information identifying one or more timed events, where each timed event identifies an operation to be performed at a corresponding instant in time as the primary content is being presented by the receiver device. One or more operations identified the timed events are initiated at the corresponding instant(s) in time.
