Tunerul este fabricat prin 2006 . El este marcat ca fiind DVB-T (2/8 K COFDM) ,vhf 174-230 Mhz , UHF 470-862 Mhz

Intrebare :receptioneaza transmisii digitale prin cablu ? Ce se intimpla cu transmisiile HD ?

M-am uitat pe standartele DVB-T si DVB-C si nu am inteles nimic .

Raspuns scurt: NU. Pentru transmisii digitale prin cablu ai nevoie de tuner DVB-C.

El e destinat posturilor digitale terestre. Pe cablu nu vei receptiona nimic digital.

Nu prinzi nici un TVR pe terestru, ca alea emit in DVB-T2. Pe DVB-T nu se receptioneaza nimic.

E bun de aruncat daca nu are si ceva parte de captura in el ( intrari A/V ).
Daca le are pe-alea atunci poate fi util ptr careva.

ok ; dar ca sa inteleg si eu ; aparatele care afirma ca au tuner DVB-T/C , au un singur tuner sau sint 2 bucati ? este o problema de hard sau de soft ?

Mai nou am vazut ca au DVB-C2 ; adica un standart nou ; difera mult ? de DVB-C ; cele care au DVB-C recepteaza norma asta noua C2 ?

In teorie tunerul terestru si cablu e unul si acelasi.Diferenta o face demodulatorul .Multi constructori fabrica acelasi aparat pentru cablu si dvb-t dar cu soft diferit.Daca e o marca mai cunoscuta ai sanse sa gasesti asa ceva.Daca e un no name poti sa uiti.

Nu. Nu poti sti acum ce va fi in viitor, asa si in cazul tau. Inversa da. Insa C2 nu-i folosit la noi.
