Systems and methods for allocating media assets to a plurality of transport streams in a mixed service system to allow simultaneous receipt of at least two media assets using a single stream selector are provided. The mix-service content delivery system comprises a content delivery server comprising control circuitry. At a first time, the first instance of the at least two media assets may be allocated to different transport streams. A user request to simultaneously receive the at least two media assets may be received. A viewing history based on the user request may be generated during a predetermined time period. At a second time after the first time, the control circuitry may allocate a second instance of the at least two media assets to a same transport stream of the plurality of transport streams. The allocations may be determined based on the generated viewing history.
