Selecting and Providing of Supplemental Content for Video Transport Stream

摘要

A method and system to facilitate localized replacement of one or more commercials or other instances of base content in a video feed with replacement-media delivered in a separate broadcast TV transport stream. A local TV station that broadcasts to an area covering a video program distributor (VPD) includes supplemental content, such as replacement commercials, within its broadcast in a manner that standard broadcast-TV receivers would disregard but that a equipment at the VPD will receive and process. The equipment at the VPD thus receives the local broadcast from the TV station and extracts from the broadcast the included supplemental content. And equipment at the VPD inserts the extracted supplemental content in place of one or more instances of base content in a transport stream that the VPD receives separately from a video-program source, so as to establish a modified transport stream for delivery to end-user TV receivers.
