The main language in use by the channel. In cases where more than one language is in use on a single soundtrack, or when more programmes share one channel, the language in use during the primetime viewing period is chosen, with other languages listed in the comments/extra information column (available from the SatcoDX World of Satellites software).
Where multiple soundtracks with different languages are transmitted, these are shown on additional lines on the SatcoDX chart.
The SatcoDX charts use three-letter codes to show the language. The codes are:
