Input docsis_scan
The input docsis_scan will scan for DOCSIS streams in the whole frequency plan. By default, the input will only look at the standard frequency plan. If you have a ATSC/QAM card, it will use the american frequency plan. If you have a DVB-C card, it will use the european frequency plan.
To speed things up, the scan will start at a frequency most likely to contain a DOCSIS stream and will continue at the begining of the spectrum afterwards.
Parameters
| Name | Type | Default value | Description |
|---|---|---|---|
| adapter | uint16 | 0 | Specify which DVB adapter to use in /dev/dvb/adapterX |
| add_input | bool | yes | If enabled, an input pre-configured for each stream found will be added. |
| buff_pkt_count | uint16 | 10 | Number of MPEG packets to read at once from the DVB card. |
| frontend | uint16 | 0 | Specify which frontend to use in /dev/dvb/adapterX/frontendY |
| scan_all_freq | bool | no | Scan each MHz additionally to the ones defined in the official frequency plan. |
| scan_qam64 | bool | no | Scan for QAM64 modulated DOCSIS stream. Those streams are very rare. |
| tuning_timeout | uint16 | 3 | Timeout in seconds when trying to tune to a given frequency. |
