[39.0E/11761H+11778H] HellasSat Cyprus

[EnoSat]

Na HellasSat momentalne prebiehaju testy Cyperskeho DTT, ktory je zaujimavy tym, ze okrem cryptovaného T2MI pidu (podobne ako ukrainsky MX7) ma navyse aj cryptovany PMT pid.
Vo vysledku to znamena, ze vyhladavanie nenajde nic a je potrebne vsetko od zakladu urobit rucne.
V lamedb je treba vytvorit transpondery

a nasledne aj virtualny kanal.
PS: pre potreby testov dvoch rozdielnych definicii DATApidu tu mame parameter c15 (OpenPLi-based images) a c18 (OpenATV-based images)

Spravnejsie nastavenie pre OpenATV-based je (bez zadanie PMT pidu c19 je to nefunkcne)

Ale pracuje aj definicia pre OpenPLi-based s parametrom c15 (hoci v OpenATV to ma za nasledok aj pokus o spracovanie DATApidu aj ako AUDIOpidu)

Ak uz mame pripaveny lamedb, mozeme si overit spracovanie DATA pidu pomocou prikazu astra --analyze

Vidime ze DATA pid je prenasany ale cryptovany, takze mozeme pripravit subor astra.conf a softcam.key

PS: od 3.3.2026 su oba transpondery v rezime FTA, takze staci naladit v prijmacoch s priamou podporou ladenia T2MI

Kód: Vybrat vše

<transponder frequency="11761000" symbol_rate="15155000" polarization="0" fec_inner="3" system="1" modulation="2" t2mi_plp_id="0" t2mi_pid="4096"/>

alebo doplnit T2MI pid do lamedb + astra-sm v prijmacoch bez podpory priameho ladenia T2MI

Aké máte skúsenosti s používaním tunera NIM (45308X) na príjem a spracovanie signálov 11760H/11778H zo satelitu 39E (alebo 11330H/11491V zo satelitu 30W), ktoré využívajú režim MIS-0 ?

PS: Zaujimave zistenie: MIS musi byt 171, pri 0 nic nejde. Realny MIS-0 je tak iba na 16E/12731H
