It's great to see how much things are cooking in C2-land these days! For this last point, David, can this be a one-off random pattern, written into the encoder/decoder code at compile time, or does it need to be negotiated for each connection? (I can't see why the latter would be needed, but I thought I'd ask.) If anyone is interested in delta encoding on the binary stream, I think this library might be a good starting place: http://michael.dipperstein.com/delta/index.html 73, Bruce VE9QRP > Thanks, > > David > > > > ------------------------------------------------------------------------------ > Virtualization & Cloud Management Using Capacity Planning > Cloud computing makes use of virtualization - but cloud computing > also focuses on allowing computing to be delivered as a service. > http://www.accelacomm.com/jaw/sfnl/114/51521223/ > _______________________________________________ > Freetel-codec2 mailing list > Freetel-codec2@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/freetel-codec2 -- http://ve9qrp.blogspot.com ------------------------------------------------------------------------------ Virtualization & Cloud Management Using Capacity Planning Cloud computing makes use of virtualization - but cloud computing also focuses on allowing computing to be delivered as a service. http://www.accelacomm.com/jaw/sfnl/114/51521223/ _______________________________________________ Freetel-codec2 mailing list Freetel-codec2@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/freetel-codec2
