ABSTRACT:
A packet encapsulator includes a filter module that identifies one or more carousel packets from a plurality of received packets. These one or more carousel packets are then stored in a packet buffer. The packet encapsulator also includes a channel queue for enqueuing packets for transmission across a broadcast transmission medium. For instance, the channel queue also receives the forwarding packets from the filter module. The channel queue also receives the one or more carousel packets from the packet buffer when at least a predetermined amount of available bandwidth exists in the broadcast transmission medium. The broadcast transmission medium may be a digital broadcast network such as a DVB handheld (DVB-H) network or a DVB terrestrial (DVB-T) network. Alternatively, the broadcast transmission medium may be a cable network.
