[QUOTE="Huevos, post: 1061369, member: 301161"] Blindscan just does a sweep of the band and saves what it believes to be the correct parameters of every transport stream it finds on the way. Those parameters just need to be "good enough" so they can be used by enigma to open that transport stream. When I rewrote that plugin years ago I added the "syncWithKnownTransponders" function to try to clean up the data returned by the blindscan binary, but that only works if the transport stream details are already in satellites.xml. So if we want perfect output how can we get it? We have to read the SI tables of each transport stream we find. This means tuning the receiver to the transport stream, reading the SDT actual, finding the TSID of the current transport stream, reading the NIT, finding all the tuning parameters that correspond to the current TSID, and then using that data as the final parameters for each transport stream. (This assumes the SI tables are correct. For some transport streams, such as the MIS multiplexes on 5 west the data is completely wrong.) So the question is, is this really necessary or is the data "good enough" and we are just being obsessive? Adding code to read each transport stream could be done but takes about 10 seconds per transport stream. [/QUOTE]
