A communication system 100 includes a content management system 221 determining broadband content availability, a video transport processing system 223 generating a plurality of packets for a content stream or in at least some of the packets comprising all packets, and a transport processing system dividing the broadband content availability into broadband content availability packets. The transport processing system 250 replaces the null packets with the broadband content availability packets in the content stream and communicates the plurality of broadband availability packets to a user device through the satellite with the content stream.
