The actual bitrate at the output of the modulator is displayed as a blue scale at the top of the menu.
Free capacity of the transponder is filled with zero packets if the subscription data does not come to
the modulator from the billing server. The capacity occupied by zero packets is indicated in the form
of a gray scale.
Free capacity is filled with subscription packages if the billing server sends TROPHY-ACCESS CAS
data to the modulator. The efficiency of data transmission is maximum. The capacity that the
subscription data occupies is indicated in the form of a yellow scale. Thanks to this technology, the
CAS data transmission efficiency is maximum.
