Welcome to the digital era!

Retuning


In 2009 we began realizing part of the digital switchover with successive activations of particular broadcasting centers in various country areas. By following the transitional frequency map published by the Ministry of Infrastructure, Transport and Networks in cooperation with the Minister of State Joint Ministerial Decision 21161/12-8-2008, G.G. 1680/Β’/20-8-2008, we managed to grant access to the digital signal to most of the country’s population [over 70%]. However, the frequencies used before the final switchover from which TV stations telecast their programs digital terrestrially, are temporary.

The use of transitional frequencies for the broadcast of digital terrestrial television programs had been defined by the State, since the necessary spectrum was not available for broadcast in final frequencies without interference.

During the final transition of all television stations into the digital terrestrial era, the necessary spectrum for broadcast in final frequencies is released. After the publication of the new frequency map with the J.M.D. 42800/5-10-2012, G.G. 2704/Β’/5-10-2012 the new frequencies are defined, while with decision 7480/Φ.386/20-02-2014 by the Hellenic Telecommunication and Post Commission as well as the J.M.D. 15715/09-08-13, G.G. 1956/B’/12-08-13, these new frequencies are defined for each provider and for each network.


Those that already watch TV digitally

For all you viewers that already receive the digital terrestrial signal through Digea you will need to retune your tuners [TV set or decoder] to the new, final frequencies as soon as the switch-off is undertaken in your area. In some cases you might need reset your tuner to its factory settings.

 

The broadcasting centers that have been activated during the transitional period [subject to J.M.D.*] and transmit in transitional frequencies are mentioned in the table below. If you belong in an area receiving coverage from the listed centers, you will need to retune your receivers on the day of your areas switch-off [third column].

How is retuning done?

To set or retune your receiver a few simple actions are needed.

Note that each device [brand] differs and may therefore follow a different procedure for the setting of channels. In the steps below the most common “wording” found on TV sets and decoders is used, therefore if you require more specific information you will have to read through your device’s manual.

 

  • For TV sets with integrated MPEG-4 decoders
  1. On your decoder’s remote press the button with the label “Menu”.
  2. Select «Settings».
  3. Select “Automatic Tuning» to automatically find and save available frequencies. Depending on the device, this option may be referred as “Automatic Search” or “Automatic Scan”. Alternatively, if you wish to save the frequencies on your own, you may choose “Manual Tuning”.
  4. Press “OK” or “Yes” or the corresponding function on your device to complete the process.
  5. Press “Exit» to exit the menu.

 

  • For TV sets with external MPEG-4 decoders
  1. On your decoder’s remote press the button with the label “Menu”.
  2. Select «Installation”.
  3. Select “Automatic Tuning» to automatically find and save available frequencies. Depending on the device, this option may be referred as “Automatic Search” or “Automatic Scan”. Alternatively, if you wish to save the frequencies on your own, you may choose “Manual Tuning”.
  4. Press “OK” or “Yes” or the corresponding function on your device to complete the process.
  5. Press “Exit» to exit the menu.

Potential problems that may appear on your decoders and recommended solutions

While going through the retuning/rescanning process you may encounter some problems which source from the way that each receiver searches and stores the digital TV programs.

Some of these cases are mentioned below, along with some steps for their resolution.

 

  • Black screen after retuning

The name of the channel/program appears normally, however the receiver projects a black screen while no sound is available. This occurs because the receiver retains the already stored channels in their previous frequencies [which are no longer active]. As a result, when it identifies them in new frequencies during the scanning process, it ignores and does not store them.

Solution:

Delete all stored programs and undertake a new program search/scan. Alternatively, you can reset your receiver to its factory settings [use your instructions manual for guidance] and then proceed with the new search/scan.

 

  • The channels are identified and stored properly, however some problems occur in the picture quality [pixelated, instant freezing]
    • If you receive the digital signal from one broadcasting center, it may be that you are in an area with limited coverage from that particular center, resulting in a weak signal. In this case, the problem in the picture quality tends to appear [or augment] during strong/severe weather conditions.

Solution:

By entering your town or municipality, start off by using the site’s coverage map to see whether your area receives better coverage by another broadcasting center that has been activated, so that you turn your antenna [aerial] towards that center.

If you do not receive coverage from that center, you may check your installation [connectivity, cables] for any deterioration and to install a signal amplifier to strengthen the reception.

 

  • On the other hand, if your area is served by two or more networks [SFN], it is possible that your receiver gets the same channel from two different frequencies and stores the one by making a choice of its own [e.g. the first one to be found during the search/scan process]. In this case, the signal of the selected channel may be weaker than the one ignored, thus resulting in limited signal reception. This is enough to cause problems during bad weather conditions.

Solution:

Start a manual channel search in order to store channels from the broadcasting center [and the corresponding SFN] that gives you strongest. The procedure is rather simple:

  1. Delete all the stored channels or reset your receiver to its factory settings by following the manual’s instructions.
  2. Use the coverage map to identify the broadcasting center that better covers your area.
  3. Jot down the network’s broadcast frequencies [SFN] to which the broadcasting center belongs to [the frequencies are mentioned in the coverage map and the frequency map].
  4. Perform a manual program search/scan only for those frequencies [the manual search usually falls in the same menu location as the automatic search].

 

  • The same channels are stored two or more times

This occurs because when your area is served by two or more different frequency networks [SFN]. When your receiver identifies the same channel more than once, it doesn’t choose it one time but rather it stores all of them.

Solution:

You can manually delete the channels that you do not want to be included in your receiver. In this case, it is preferred that you retain the channels of the broadcasting center that gives you the better signal quality.

Alternatively, you can delete all the stored channels and proceed with a manual search/scan only for the frequencies of the broadcasting center that offers you the best signal.
