An aspect of the invention relates to a method and apparatus for multiplexing content. In one example, a first transport stream is received. The first transport stream includes a sequence of burst cycles, each of the burst cycles having a plurality of packet bursts respectively associated with a plurality of primary services. In one example, a primary service is a national service. A packet burst stream is received that is associated with a secondary service. In one example, a secondary service is a regional service. The first transport stream is multiplexed with the packet burst stream to produce a second transport stream. The second transport stream includes a deterministic relationship between the plurality of packet bursts in each of the burst cycles and packet bursts of the packet burst stream. Additional packet burst streams associated with additional secondary services may be received and multiplexed in a similar manner.
