WooshCom's proprietary Fixed Rate Null Packet Filtering algorithm is the only Null Packet filtering algorithm on an aggregator in the marketplace which provides an MPEG compliant output stream that produces flicker free results on even older set-top boxes. It may be enabled on an ASI port-by-port basis, providing further bandwidth optimization by reducing the number of MPEG NULL packets.
Operators may scale the number of ASI ports to fit their needs alleviating the tendency to overbuy unnecessary ports. Purchasing one additional CSX-1641 module achieves sparing at very low cost. Together these factors yield the lowest deployment cost.
