sample_dvb_api

This is a simple tuning tool for ISDB-S/ISDB-T using Linux DVB API tuners.

How to build

git clone https://github.com/katsuster/sample_dvb_api
cd sample_dvb_api
autoreconf -fi
./configure
make

How to Use

ISDB-S

sample_dvb adapter S [BS|CS110] ch TS-ID

ISDB-T

sample_dvb adapter T ch

'adapter' specify the number X of DVB API device /dev/dvb/adapterX/. Please specify 0 if you use /dev/dvb/adapter0.

'ch' specify the physical channel number.

For ISDB-S:

  • Specify transponder number X of BS-X or NDX
    • Please refer the satellite transponders list that was publised from Ministry of Internal Affairs and Communications
  • Available range is BS-1 to BS-23 (for BS), ND1 to ND24 (for CS110)
    • Please specify only number part, not need 'BS' or 'ND' prefix
  • Center IF frequency of BS ch1 (BS-1) is 1049480kHz (1.049GHz)
    • Local-IF is typically 10.678GHz for BS and CS110

For ISDB-T:

  • Available range is 13 to 52.
  • Center frequency of ch13 is 473142857 Hz (473MHz) of ISDB-T
    • Channel bandwidth is 6MHz, so ch14 is 479MHz, ch15 is 485MHz, ..., ch52 is 707MHz

'TS-ID' specify the unique ID of satellite network of BS or CS110. Please search the information or refer the standard documents such as ARIB TR-15.
