Manual Scan Menu OE2.5

  • couple of transponder's parameters are shown Auto; Auto; Auto
    if scan that way, stored services(lamedb) looses compatibility of export to any other Dreambox's model


    p.s.
    order of `FEC` and `S2 Modulation Type` must be swapped in parameters list,
    because after you have set FEC and go step down to S2 Type and change it,
    FEC is changed by self and you have to go up to set FEC again


    and yes, why it were made as separate parameter instead extend Transponder type:
    DVB-S; DVB-S2; DVB-S2 8psk; DVB-S2X

  • Absolutely nothing wrong here. And no it doesn't lose compatibilty as the lamedb is written with the correct values. Also there is NO "DVB-S2X" it's just an extension of some modulations and FEC values to DVB-S2, Linux API doesn't even know DVB-S2X. There is also no need to enter FEC or Modulation, as Auto always works and writing the right values to lamedb.

  • isn't obvious?
    when some particular parameter is stored as Auto
    then tuner has to find right value each time of zap


    look, my lamedb has stored particular value(on/off) (Pilot as example)
    but when open `Manual Scan` section it is changed to Auto
    and after do scan with that Auto parameter lamedb loses info which it had before

  • The most tuners only do auto in background even if you set the values (FEC, Modulation, Pilot and so on...) manually. :winking_face:
    And again parameters are not lost after scan, as DreamOS is detecting the correct values on scan and writing them to the lamedb. Only unknown values are written as Auto, e.g. new FEC values for DVB-S2X...


    Pilot is maybe a bug, but should generally handled the same as the other parameters, after scan is the detected value written to lamedb.


    And as said most tuners usually do a "blind" detection of all parameter and don't care about the values stored in lamedb at all (except for Freq, Polarization and Symbolrate).
