Methods and computer program products for subcontent tagging and playback
摘要:
A content provider inserts at least one begin tag and at least one end tag into a broadcast program. The at least one begin tag and at least one end tag defines a video clip segment for the broadcast program. The content provider transmits the broadcast program including the at least one begin tag and the at least one end tag over a network to a digital video recorder (DVR). Upon the broadcast program ending, the content provider transmits a wrapper over the network to the DVR. The wrapper includes wrapper information comprising at least one of a sponsor advertisement, a trailer broadcast, a header broadcast, or a summary of one or more video clip segments.
