553702 T.0X TWIN QPSK/PAL Stereo CI Prof CAM TELEVES

Περιγραφή:

Ο μεταφορέας διαμόρφωσης 553701 TWIN QPSK-PAL CI με PROF CAM, επιτρέπει τον χρήστη να επιλέξει δύο (2) κανάλια (TV/radio) απο αυτα σε κάποιο transponder (της ίδιας μπάντας και πολικότητας), και να τα μετατρέψει σε δύο (2) κανάλια VHF/UHF PAL, και με δυνατότητα stereo διαμόρφωσης. Η μονάδα επιτρέπει πρόσβαση σε κωδικοποιημένες υπηρεσίες μέσω της χρήσηs CAM για την αποκωδικοποίηση τους . Διαθέτει δύο 3.5 mm για την είσοδο της συχνότητας , IF loop-through για το πέρασμα του σήματος σε άλλα modules και RF loop-through για την έξοδο και μίξη άλλων καναλιών για περαιτέρω ενίσχυση.

Product description:

The unit allows access to scrambled services by using a conditional access module (CAM) that performs the services descrambling. Descrambling is only allowed for the module B. The selection of parameters (input frequency, SR, output level, output frequency, …) is performed by using the programmer ref. 7234, which is plugged in its own socket on the front of the unit. It is also possible to control the unit from a PC as
described in Section 6. The normal operation of modules is as follows: – Module A: All changes are made and/or
previewed in real time, except for some cases to be discussed in the corresponding section. – Module B: To make and/or preview changes in real time, you have to save them (long press on key ), except for some cases to be discussed in the corresponding section.
The TWIN QPSK-PAL CI unit allows the user trasmodulate two channels (TV or radio) selected from those in two satellite transponders in the same band and polarisation, into two VHF/UHF PAL channels, with the possibility of stereo modulation. To do this, the unit demodulates the two QPSK input channels (transponders) to obtain the
MPEG-2 TS signal (Transport Stream MPEG-2) for each of the input channels to carry out the subsequent modulation of both audio and video signals of the selected program, to any channel or frequency between 46 and 862MHz.
The TWIN QPSK-PAL CI unit features:
– An IF loop-through for the input connectors on the top of its front, in order to enable the passage of the input signal to other modules. On the other hand, allows current by-pass through the IF input cable (13 or 17 Vdc) to power the LNB as well as to generate and send out a 22KHz tone through this input to select the LNB oscillator.
– A RF loop-through for the output connectors on the bottom of its front, in order to mix the channels for further amplifi cation.
– A slot for inserting a conditional access module (CAM) for the module B of the TWIN unit.
– Two 2.5 mm jack connectors used to connect the headend controller CDC T-0X via a control BUS.
– Two 3.5 mm jack connectors that make available in baseband the two audio & video channels of
each module.
