Adding and configuring DVB-C channels

Configuration of DVB-C channels is done under Account > DVB-C channels. Here you define the DVB-C channels available in your network. All channels in the resulting channel can then be selected in the user interface when you set up a DVB-C test or monitoring.

The following parameters need to be defined for each DVB-C channel:

  • Name: DVB-C channel name. Shown in Netrounds when starting DVB-C measurements.
  • Frequency: The frequency of the channel in Hz.
  • Symbol rate: The symbol rate of the channel, stated as symbols per second.
  • FEC: The Forward Error Correction for the channel. Valid settings are: 1/2, 2/3, 3/4, 5/6, 7/8, and NONE.
  • Modulation: The modulation used for the channel. Valid settings are: 16-QAM, 32-QAM, 64-QAM, 128-QAM, and 256-QAM.
  • Pnum: The program number of the channel.

Discovering DVB-C channels

Netrounds has a built-in channel discovery function for DVB-C channels.

  • Change "Test Agent:adapter" to the Test Agent that is connected to the DVB-C distribution network.
  • Indicate the frequency, symbol rate, FEC, and modulation conforming to the TV distributor.
  • Click Discover. The discovery scan will only cover the channels in the network information table in the DVB-C stream with the frequency given. To get all available channels, you may have to perform this procedure repeatedly.

Note: The discovered channel plan will populate the channel list automatically and remove any channels previously listed.

Uploading your channel plan as a CSV file

Alternatively, instead of entering channels manually in the user interface, you can upload a channel plan as a comma-separated file (*.csv).

This file must have one channel per line, defined according to the following syntax:

channel_name,frequency,symbol rate,FEC (1/2,2/3,3/4,5/6,7/8,NONE),modulation (16-QAM,32-QAM,64-QAM,128-QAM,256-QAM),pnum

Channel names cannot contain commas (,).

Please make sure that the file is encoded in UTF-8 format if it contains international characters. The encoding can be specified in the text editor settings.

Note: Uploading a new channel plan will overwrite all existing channels.
