Method and System for Localized Replacement of Base Content in Video Feed, with Replacement-Media Delivered in Broadcast-TV 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.

主权项

1. A method comprising:
receiving, by a computing system at a local video-program-distributor (VPD), a first transport stream broadcast from a television (TV) station, the received first transport stream including standard media content indexed for processing by standard broadcast-TV receivers and supplemental media content not indexed for processing by standard broadcast-TV receivers; extracting, by the computing system, from the received first transport stream, at least one portion of the supplemental media content; receiving, by the computing system, from a source other than the TV station, a second transport stream for delivery by the local VPD to customer premises equipment (CPE) receivers served by the local VPD, the received second transport stream including one or more instances of base content; injecting, by the computing system, the extracted portion of the supplemental media content into the second transport stream in place of at least one of the one or more instances of base content to establish a modified version of the second transport stream having the extracted portion of the supplemental media content injected in place of the at least instance of base content; and outputting the modified version of the second transport stream for transmission by the local VPD to the CPE receivers served by the local VPD.
