and populating the station manifest with an indication of the station-specific content segments and associated timings. ### Claim 8 (depends on 3) The computer-implemented method of claim 3, comprising: receiving an ad manifest; and generating a third tier manifest based on the second tier manifest and the received ad manifest, wherein the third tier manifest enables dynamic ad insertion. ### Claim 9 (depends on 8) The computer-implemented method of claim 8, wherein the third tier manifest is generated specifically as a customization for a particular distribution channel. ### Claim 10 (depends on 1) The computer-implemented method of claim 1, wherein: the first manifest comprises an indication of segments of the first content, the first content comprising live video content; and the second manifest comprises an indication of segments of the second content, the second content comprising a file video. ### Claim 11 (depends on 1) The computer-implemented method of claim 1, comprising: generating a plurality of second tier manifests, each providing a different schedule, selection, or schedule and selection of the first segments and second segments in conjunction with associated second tier content. ### Claim 12 (depends on 11) The computer-implemented method of claim 11, wherein the plurality of second tier manifests comprise a corresponding second tier manifest for each of a plurality of stations that use at least a portion of the first segments, at least a portion of the second segments, or both. ### Claim 13 (depends on 1) The computer-implemented method of claim 1, comprising: inserting a graphic into at least a portion of the first segments, at least a portion of the second segments, or both, by: identifying within the first tier manifest, a graphical insertion opportunity; generating alternative segments to original segments occurring within the graphical insertion opportunity, the alternative segments comprising the original segments modified to include the graphic; and adjusting subsequent playback to include the alternative segments by: modifying the first tier manifest to indicate the alternative segments in lieu of the original segments; or replacing the original segments with the alternative segments. ### Claim 14 A tangible, non-transitory, computer-readable medium, comprising computer-readable instructions that, when executed by one or more processors of one or more computers, cause the one or more computers to: receive a first manifest associated with first content and a second manifest associated with second content; generate a first tier manifest comprising an indication of first tier segments describing a playback schedule of the first content and the second content, the first tier manifest comprising a composite of the first manifest and the second manifest that indicates first segments of the first content and second segments of the second content; and provide the first tier manifest to enable generation of a second tier manifest, wherein the second tier manifest is generated based on the first tier manifest and a station manifest. ### Claim 15 (depends on 14) The tangible, non-transitory, computer-readable medium of claim 14, comprising computer-readable instructions that, when executed by one or more processors of one or more computers, cause the one or more computers to: receive the station manifest; generate the second tier manifest based on the first tier manifest and the received station manifest; and cause provision of the first tier segments and segments of station-specific content to a multichannel video programming distributor (MVPD), an over-the-top (OTT) platform, or both, using the second tier manifest, by: providing the second tier manifest to the MVPD, the OTT platform, or both, to instruct the MVPD, the OTT platform, or both, how to acquire the first tier segments and the segments of station-specific content; or generating and providing, to the MVPD, the OTT platform, or both, a transport stream based upon second tier manifest, wherein the transport stream comprises the first tier segments and the segments of station-specific content. ### Claim 16 (depends on 14) The tangible, non-transitory, computer-readable medium of claim 14, comprising computer-readable instructions that, when executed by one or more processors of one or more computers, cause the one or more computers to: receive a third manifest, comprising an indication of customized content for a particular distribution channel;
