摘要
A data transport container is used to transport information from a content provider network node to an advertisement insertion network node. The data transport container encloses a media program, program metadata, advertisement metadata, and advertisement selection code. The advertisement insertion network node selects among a plurality of advertisements, which may also be received through the data transport container, in response to at least the advertisement selection code and the advertisement metadata. The selected advertisements are combined with the media program in response to the program metadata to generate a combined media program. The combined media program is communicated to a subscriber equipment unit. The data transport container may contain Material eXchange Format (MXF) encoded content. Accordingly, the advertisement insertion network node may be configured to decode MXF encoded content of the data transport container to extract the media program, the program metadata, the advertisement metadata, and the advertisement selection code into separate files.
