Transponder Management

 

Use the Transponder Management dialog to manage all digital TV and data channels for the currently selected satellite. All channels are listed in the Transponder list, where they can be edited, deleted or tested for signal reception. Use Search and Scan to automatically update the entire Transponder list.

Search and Scan

Rather than updating channels manually, Search and Scan automatically updates all of the programs in the program listings and updates the entire Transponder list, beginning at Start Frequency (the frequency of the first channel) and ending at End Frequency (the frequency of the last channel). To perform a Search and Scan:

  1. Verify signal reception for the currently selected satellite. Return to the Satellite Settings tab and click Transponder Management.
  2. Under the Search and Scan section, select the Auto-Detect Symbol Rate checkbox. Use the default values or enter: the frequency of the first transponder at Start Frequency, the frequency of the last transponder at End Frequency, and the Frequency Step Size.
  3. Click the Search and Scan button and monitor scan progress indicators.



  4. When Search and Scan is complete, the Transponder list will reflect newly updated or added digital TV and data channels. The program listing will automatically be updated.
  5. Click Close to exit the Transponder Management dialog.

Search and Scan Textboxes and Progress Indicators

Start Frequency, End Frequency, and Step Size

Each TV channel is broadcast by its own transponder aboard the satellite. The Start Frequency is the frequency of the first transponder on the satellite (or you can enter an arbitrary frequency that marks the beginning of the scan). The End Frequency is the frequency of the last transponder on the satellite (or you can enter an arbitrary frequency marking the endpoint of the scan). Step Size is the scan increment. Search and Scan will scan every increment between the Start Frequency and the End Frequency.

If you do not wish to use default values, the values for any particular satellite can be found on the Internet at www.satcodx.com, www.lyngsat.com, or www.sat-address.com. These sites list different satellites' transponders and the frequency of each transponder. Find your satellite on the web site. Then find the highest and lowest transponder frequencies for your satellite and enter them as the Start Frequency and End Frequency.

Scan Progress Indicators

After Search and Scan is clicked, the Scanning Status textbox describes the events of the scan as they happen in terms of a channel's PIDs (packet ID codes) or updating tables such as the NIT (network information table), PAT (program association table), PMT (program management table) or CAT (conditional access table). The Scan Progress bar displays the progress of the scan relative to the whole satellite, which possesses many transponders. The Transponder Progress bar displays the progress of the scan relative to the single transponder currently being scanned.

Manually Adding, Editing, or Deleting an Individual Transponder

Any individual channel can be tested for signal reception by clicking Edit on the Transponder Management dialog. New channels can be tuned and manually be added to the Transponder list.

To manually add a transponder to the list or to edit an existing transponder, you will need to know the frequency, symbol rate, and polarity of the transponder that you want to add. (If you do not have these settings, use Search and Scan.)

  1. On the Transponder Management dialog, highlight the desired transponder on the Transponder list.
  2. To delete the transponder, click Delete.
  3. Click Add or Edit to launch the Add Transponder or Edit Transponder dialog, which appears with the selected satellite's name in the greyed Satellite drop-down list.



  4. Under Transponder Settings enter signal parameter values to tune the tuner to the selected transponder; obtain these values from your service provider (or use the default values.)
  5. Click Tune and monitor the Signal Strength indicator.
  6. When you obtain the maximum percentage Signal Strength, click OK to return to the Transponder Management dialog. The new transponder now appears on the Transponder list.
  7. Click Close to exit the Transponder Management dialog.
