An enhanced television recorder and player includes a trigger inserter unit that inserts triggers into vertical blanking intervals of audio/video signals. The triggers point to resources that are stored in a storage medium or are available from a network, where the triggers, audio/video signals, and resources together can comprise a Transport Type B transmission. The audio/video signals having triggers in the vertical blanking intervals are stored in the storage medium, and during playback by a stream simulator unit, simulate a Transport Type A transmission, transformed from the Transport Type B transmission. Requested resources may be retrieved from the storage medium or from the network by a proxy unit of the receiver unit.
