High Speed Digital Video on Legacy Aircraft Wiring

The low data rate of the MIL-STD-1553B bus is limiting the capability and performance of current applications. These applications and others under development could be augmented by increasing the data rate under which these systems communicate. The Joint Helmet Mounted Cueing System (JHMCS) is one example of a system that could benefit from the increased data rate. The current 1553 protocol supports a maximum data rate of only 1Mbps per bus. This rate causes degradation in the JHMCS displayed video resulting in blanked lines, blanked frames, or possibly no display at all. DataSoft will provide a high speed dynamic communication link on the existing 1553 wiring that will adapt to the changing physical and electrical conditions inherent on the 1553 bus. The DataSoft approach will dynamically adjust the signal to the changing environment on the 1553 bus that will result in higher throughput. BENEFIT: Our approach will provide high speed data link that can be used for the JHMCS as well as other systems that require high speed data over MIL-STD-1553 wiring. The DataSoft solution reduces integration costs because it dynamically adapts to the physical and electrical changes of the 1553 bus. The DataSoft solution is scalable and will provide the capability of multiple sets of transceivers to operate on the same bus.
