recskapa

Based on recdvb from http://cgi1.plala.or.jp/~sat/

Description

recskapa - command to record DVB-S/S2 and QAM256 from linux DVB devices, designed specifically for domestic SkyPerfecTV and SkyPerfecTV Hikari service. Integrates support for ARIB-STD-B1 decoding via libpcsclite. Only tested on command line and with mirakurun.

Difference from original?

• Remove http/udp streaming

• Remove IPC to extend recording/retune

• Remove autoconf/update Makefile

• Modify file writing in single blocks (was chunked for http/udp)

• Added configuring tone/voltage to switch JCSAT3A/4B satellites

• Added external channel configuration file instead of hardcoding transponders/services

• Added setting frequency, tone and polarization from command line to avoid duplicating data inside channels.conf

• Added support for SkyPerfecTV Hikari tuning (DVB-C Annex B / J.83B)

• original - http://cgi1.plala.or.jp/~sat/ (link dead as of September 2024)

How to use (updated)

• See --help

• Example with murakurun config tuners

- name: TBS6903(A)
  types:
    - SKY
  command: recskapa -a 0 -l <satellite> -f <freq> -p <polarity> -b -s - -

- name: TBS6209SE(A)
  types:
    - SKY
  command: recskapa -i -a 0 -f <freq> -b -s - -

• Note, SkyPerfecTV Hikari places all 20 transponders in VHF/UHF frequency range between 112.8 and 587.3 MHz. Main NIT can be obtained by tuning 64-QAM DVB-C channel at 375 MHz and doing NIT scanning.
• Some DVB cards have multiple frontends on same adapter, so command line option -n (--frontend) can be used to select it.
• Note, it's still possible to use channel configuration file below, but not required for either satellite or hikari service as all tuning details can be provided on command line directly.
• To use channels config, add -c /path/to/channel.conf, omit -i, -l, -f , -p arguments and call the command like so:

 recskapa -c /path/to/channel.conf -a 0 -b -s <channel> - -

• Note, channel.conf is not supported for hikari service.
