Abstract:
1. A method to feed transmitters operating in multiple single frequency network areas with diversified content through a single transport stream, the method comprising: receiving multiple transport streams with content intended for the multiple single frequency network areas; processing the received multiple transport streams to determine information about packets of each of the received transport streams; selecting packets from the received multiple transport streams; slicing the selected packets into a block of packets; composing a metric feed packet (MFP) including information indicating whether packets in the block of packets are to be dropped at any one of multiple location re-multiplexers before being broadcasted to a particular single frequency network of the multiple single frequency network areas; inserting the MFP before or after the block of packets; and outputting the single transport stream including the block of packets and MFP to the location re-multiplexers of the multiple single frequency network areas.
