TV Recording

You can record digital TV programs with a USB DTV dongle with DVB-T, DVB-S/DVB-S2 standard or HDHomeRun with DVB-T standard (sold separately) plugged into your Synology NAS. Before proceeding to record your favorite TV programs, please make sure you have plugged in a dongle compatible with your Synology NAS and performed a thorough channel scan.

For the complete list of supported DTV dongles, please visit Synology's website.

Note:

  • Only DSM admin (or users belonging to the administrators group) or users with the DTV Control privilege can set up TV recording tasks. Other users have no access to this function.
  • The maximum number of tuners that can be connected to Synology NAS is eight. Please note the number of tuners supported by each individual dongle varies. To confirm, please consult the User's Guide that comes with your DTV dongle.
  • Digital TV recording via DTV dongles has been in the limited support status since September 2017. 

Channel Scan

Video Station supports two standards for the broadcast transmission of digital terrestrial and satellite signals: DVB-T (Digital Video Broadcasting - Terrestrial) and DVB-S (Digital Video Broadcasting - Satellite). You can choose a dongle of either of the standards to scan channels depending on the implementation of the dongle plugged into your Synology NAS.

When starting to use the DTV function by clicking DTV on the control bar, you as DSM admin or users belonging to the administrators group must perform a complete channel scan before proceeding to record TV programs and manage the streaming service.

To perform a channel scan:

  1. Go to the DTV section on the left panel, and click [Dongle name].
  2. Depending on the implemented standard of the dongle you have selected, do either of the following:
    • For DVB-T standard:
      • Tuner: Depending on the model of DTV dongle, the number of supported tuners varies. Select the tuner you want for channel scan. Note that channels available for the selected tuner may be different from one to another. Every time you view TV program guide, record programs, set up the recording schedule, or select channels for live streaming, you need to select a tuner from the DTV drop-down menu first, so that you can manage options corresponding to the selected tuner.
      • Country/Region: Select your country and region (if applicable). You cannot scan channels for a place where you are not located.
      • Signal type: This option is only available for the HDHomeRun tuners. Select a TV signal type available in your location.
  3. For DVB-S/DVB-S2 standard: Regarding the detailed instructions on DVB-S/DVB-S2 dongle configuration, please refer to the User's Guide that comes with the product.
    • Tuner: See here.
    • Satellite: Depending on whether you select a default or manually-added satellite, do either of the following:
      • Default satellite: Several default satellites are available for your choice from the drop-down menu. If you have selected a default satellite, its corresponding LNB type will be automatically applied.
      • Manually-added satellite: If your satellite is absent from the list, you may manually add a new satellite by specifying its name and longitude and then selecting an LNB type.
  4. LNB type (low-noise block downconverter): Several default LNB types are also available from the drop-down menu. Depending on the satellite selected, the LNB type varies. You may click Settings to configure advanced settings for channel scan, including the following:
    • LNB: Give a name to the LNB type, edit LNB information, and modify the DiSEqC settings.
    • Transponder: Add transponders or edit the parameters of transponders: Frequency, Symbol rate, Polarization.
  5. Click Scan to start. A progress bar will appear in the middle of the window indicating the percentage of completion of the scan. It may take a while for the scan to finish.
