Open AlbertEinsteinGlitchPoint opened 6 years ago

AlbertEinsteinGlitchPoint commented 6 years ago

Hi i am checking the TUNE.c code and so far have not seen anything mentioning isdb-t

is this done via DVB-T scan util?

i am using correct freq= on mumudvb but its not scanning the channel

but if i use dvbv5-scan util, using same frequency i can lock signal to the channel

dvbv5-scan -F /etc/myconfig/channels.txt INFO Scanning frequency #1 581142857 Lock (0x1f) Signal= -63.60dBm C/N= 14.20dB Layer A: Signal= 36.10% C/N= 28.03% error while waiting for PAT table INFO Scanning frequency #2 473142857 Timeout(0x20) Signal= -82.40dBm Layer A: Signal= 17.46% INFO Scanning frequency #3 479142857 Timeout(0x20) Signal= -69.60dBm Layer A: Signal= 30.15% INFO Scanning frequency #4 485142857 Lock (0x1f) Signal= -73.50dBm C/N= 15.20dB Layer A: Signal= 26.28% C/N= 30.03% error while waiting for PAT table

aparently further digging

this is the data used to scan the channels freq. txt file

info("initial transponder %u %d %d %d %d %d %d %d\n",

t-> param.frequency, t-> param.u.ofdm.bandwidth, t-> param.u.ofdm.code_rate_HP, t-> param.u.ofdm.code_rate_LP, t-> param.u.ofdm.constellation, t-> param.u.ofdm.transmission_mode, t-> param.u.ofdm.guard_interval, t-> param.u.ofdm.hierarchy_information);

T 473142857 6MHz AUTO AUTO AUTO AUTO AUTO NONE # channel 14

will do further testing

Hello! I'm having issues on ISDB-T channels as well, neither w_scan nor mumudvb can find any channels but Cesbo Astra does. My server runs on Ubuntu 18.04LTS Server edition. Please find some screen shots:

Also, dvbv5-scan finds all channels w/o a problem. I guess my config files may be missing something.

Thanks!

Hello

Please try with MuMuDVB 2 and ISDBT as delivery system.

1.7 does not support IDSBT
