In certain embodiments, a digital television broadcast method involves generating a digital television signal having one or more transport streams; where data in at least one of the one or more transport streams that supports non-real time (NRT) services, where such data comprises an Internet protocol (IP) stream of packets containing NRT content including a FLUTE file description table (FDT), a NRT information table (NRT-IT), and a Service Map Table (SMT); where the NRT-IT contains a content ID that relates the NRT-IT to the FLUTE FDT, and where the SMT contains a service ID that relates the SMT to the NRT-IT table; and outputting the one or more transport streams for broadcast as a digital television signal. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract. |
