Abstract
In accordance with an embodiment, a best-effort service is divided into packets for best-effort digital broadcast transmission. The packets are encapsulated with an encapsulation protocol that uses a packet order defining field. The encapsulated packets are inserted into an unused portion of a slot of a digital broadcast transmission frame. Then, the encapsulated packets are repeatedly inserted into the unused portion of the slot of the digital broadcast transmission frame in a packet-carousel fashion. And the transmission frame is digitally broadcast. In accordance with an embodiment, a digital broadcast transmission is received. Encapsulated packets that have been repeatedly broadcast in a packet-carousel fashion are accessed from a best-effort portion of a digital broadcast transmission frame slot. And a best-effort service is composed from the encapsulated packets by combining the encapsulated packets in an order based on a packet order defining field of the encapsulated packets.
