#8734: Enabling decryption check increases number of FTA muxes/channels found
-----------------------------------------------------------------+----------
Reporter: Nick Morrott <knowledgejunkie (at) gmail (dot) com> | Owner: danielk
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - Channel Scanner | Version: Trunk Head
Severity: medium | Mlocked: 0
-----------------------------------------------------------------+----------
Using the same configuration as reported in #8726.
Scan details: full UK DVB-T scan using Sutton Coldfield transmitter with 6
available muxes. Default signal/tuning timeouts of 1000/3000ms. ALL
services (DVB+MPEG) scanned.
Irrespective of whether channel decrytpion testing is enabled in the
scanner, a single mux is found during a full scan. The NIT contains
details of the 5 missing missing muxes, which the scanner tries to tune
to. See #8731 for more details of this.
However, if decryption testing is disabled (default), only 4 of the 5
muxes found in the NIT are tuneable. When decryption testing is enabled,
all 5 of the muxes seen in the NIT are tuneable, and all DVB channels are
successfully configured.
I have repeated this test more than once at different times of the day,
and have observed the same results. The logs (attached) do suggest that
the signal acquisition time is borderline for this particular card (taking
of the order of 900ms with a signal timeout of 1000ms) but I do not
understand how the decryption testing is influencing this (which surely
only occurs once a lock is obtained on a mux?).
