Rows

The rows have the following functions

Basic Settings

Enabled: If selected, this tuner/adapter will be enabled and will become available to receive broadcasts or programmes.
Name: The name of this tuner.
Over-the-Air EPG: Enable over-the-air programme guide (EPG) scanning on this input device.
Networks: Associate this device with one or more networks.
Init Scan: Allow the initial scan tuning on this device.
Idle Scan: Allow the idle scan tuning on this device.
Power Save: If enabled, allows the tuner to go to sleep when idle.
Skip Initial Bytes: If set, first bytes from the MPEG-TS stream are discarded. It may be required for some drivers / hardware which does not flush completely the MPEG-TS buffers after a frequency/parameters change.

Advanced Settings

Priority: The tuner priority value (higher value = higher priority to use this tuner).
Streaming Priority: The tuner priority value for streamed channels through HTTP or HTSP (higher value = higher priority to use this tuner). If not set (zero), the standard priority value is used.

SAT>IP Specific Rows

Full Mux Rx mode supported

Enable if the SAT>IP box supports the full mux rx mode (pids=all)
note: no comma after 'Enable'

Signal scale (240 or 100)

Some SAT>IP boxes only report a 0-100 (percentage) signal strength. If your signal strength reports as too low, try setting this to 100.

Maximum PIDs

Maximum supported PIDs in the filter of the SAT>IP box.

Maximum length of PIDs

Maximum length in characters for the command setting PIDs to the SAT>IP box.

Addpids/delpids supported

Enable if the SAT>IP box supports the addpids/delpids command.

PIDs in setup

Enable, if the SAT>IP box requires pids=0 parameter in the SETUP RTSP command.

Force pilot for DVB-S2

Enable, if the SAT>IP box requiest plts=on parameter in the SETUP RTSP command for DVB-S2 muxes.

UDP RTP Port Number (2 ports)

Force the local UDP Port number here. The number should be even (RTP port). The next odd number (+1) will be used as the RTCP port.

Satellite Positions

Select the number of satellite positions supported by the SAT>IP hardware and your coaxial cable wiring.

Master Tuner

Select the master tuner.

The signal from the standard universal LNB can be split using a simple coaxial splitter (no multiswitch) to several outputs. In this case, the position, the polarization and low-high band settings must be equal.

If you set other tuner as master, then this tuner will act like a slave one and tvheadend will assure that this tuner will not use incompatible parameters (position, polarization, lo-hi).

Next tune delay in ms (0-2000)

The delay before tuning in milliseconds after tuner stop. If the time after previous start and next start is greater than this value - the delay is not applied.

Send full PLAY cmd

Send the full RTSP PLAY command after full RTSP SETUP command. Some device firmwares requires this to get MPEG-TS stream.

Force teardown delay

Force the delay between RTSP TEARDOWN and RTSP SETUP command (value from 'Next tune delay in ms' is used). Some devices are not able to handle quick continuous tuning.
