Editing Channels

After having selected either a satellite position (root) or a channel, you can go to the Edit tabsheet. If it concerns a root entry, the following settings appear:

  • Name: In this input field you may modify the root folder name. Finish by clicking the Apply button.

  • DiSEqC: The Digital Satellite Equipment control is a digital impulse, used for sending signals to the multiswitch. It is used in particular to switch between several satellite positions (for example Astra and Eutelsat). In this list you can determine the DiSEqC adjustment for all channels located in the root folder. Finish by clicking Apply. Important: If your satellite reception system is equipped with such a DiSEqC switch, the DiSEqC adjustment is a must! Without it, you probably can't receive anything. You may use an already available digital satellite receiver, in order to check, which DiSEqC adjustment is suitable for which satellite position.

  • Delete: Deletes after a safety query the selected folder with its whole content. Is is recommendable to remove all unnecessary satellite positions from the standard channel list to improve the processing speed. Please note: There is no way to undo it. Once deleted, the entries are gone. So it is a good idea to create a backup copy of the file channels.dat. It is located in the DVBViewer folder and contains the entire channel list.

After having selected a channel, the Edit tabsheet shows a couple of settings. The three buttons at the bottom of the tabsheet have the following meaning:

  • Remove: The channel is deleted from the list after a safety query.

  • Name: Here you may rename the channel. But be carefull: If there is a pending timer recording for this channel, it will not work anymore, because the DVBViewer cannot find the channel under its new name! Even if the channel is stored in the favourite list (see channel menu), it must be stored again with its new name, ot­her­wise it cannot be tune

  • Encrypted: Here you will find a checkmark, if the channel found by a channel scan is encrypted. Since the DVBViewer does not support the playback of encrypted channels, this adjustment has no meaning.

  • Exclude from the EPG: A checkmark here excludes an unwanted channel from the time-specific EPG (which shows all transmissions running at a point in time). Thus the EPG representation can be limited to a meaningful measure.

The remaining fields on the register card contain technical data, which are needed to tune the channel correctly. If a channel cannot be received, mostly the reason can be found here. There are different Internet pages, which provide the channel data, for example

If a new channel is announced in the DVBViewer forum, the required data will also be listed. After entering the values and clicking on Add the new channel is available in your list. Here a few short notes explaining the meaning:

  • Frequency: The frequency of the data stream, in which the channel (together with other channels) is encoded.

  • Symbol rate: Indicates the amount of data, that is transferred per second in the data stream.

  • Polarization: The orientation of the electromagnetic waves received from the satellite, which can be distinguished by the LNB (the unit that receives the beam focussed by the dish). By using horizontal and vertical polarization more channels can be fitted into a frequency range. The receiver must indicate the desired polarization to the LNB by supplying it with a certain voltage (14/18 V), so it can align to it.

  • FEC: Type and extent of the Forward Error Correction in the data stream.

  • PID: The Program Identifier is required to filter the correct packages out of the data stream. Uncorrect PIDs may cause different problems (Missing video/audio, error messages).

  • LNB-Selection: This is a signal frequency, sent by the receiver to the LNB, in order to select a certain frequency range. There is a Low Band, which is normally used for analog transmissions (but more and more gets occupied by digital streams), and also a High Band assigned for digital transmission. The correct adjustment for Low Band channels (below 11700 MHz) is None. For High Band channels (above 11700 MHz) 22 kHz is appropriate.

  • LNB frequency: The frequencies sent by the satellite are that high, that they cannot be transported by cables. Therefore the LNB creates its own high frequency signal, which is used to "mix down" the satellite signal to a frequency suitable for cable. A LNB frequency of 9750 MHz is appropriate for Low Band channels, 10600 MHz for High Band channels (see paragraph above).

  • DiSEqC: In this list you may assign an individual DiSEqC adjustment to the channel. It has the same meaning as the general adjustment for the root folder (see above). The SkyStar2 only supports DiSEqC 1.0 and 1.1.

If a new channel is announced in the DVBViewer forum, the required data will also be listed. After entering the values and clicking on Add the new channel is available in your list. Here a few short notes explaining the meaning:
