    Default Ce parere aveti de aceasta scula??? Mie mi se pare super.

    AB IPBox 510TS twin-tuner cu tuner DVB-S si DVB-T, deci se pare ca se poate urmari pe el si canale de pe satelit si canale digitale terestre in acelasi timp. Pe de alta parte ei zic acolo de o chestie ca avand acest receiver poti urmari doua canale diferite in acelasi timp la 2 televizoare diferite . DVB-S2 este cumva MPEG 4 sau HDTV ? Ca aici scrie ca stie si DVB-S2 .

    Daca nu gresesc DVB-S2 este un standard de modulatie si nu are neaparat legatura cu streamul transmis. Din cate inteleg stie de modulatie DVB-S2 dar pentru HDTV trebuie un PC catre care sa redirectezi streamul H264 sau MPEG2 HDTV.

    Bafta.

    DVB-S2 este doar tipul de modulatie folosit si nu are legatura cu tipul compresiei (MPEG 2 sau H.264/AVC) sau rezolutia imaginii (SDTV sau HDTV) putand fi folosit deoportiva cu oricare dintre acestea.Faptul ca in prezent este folosit doar la transmisiile HDTV/H.264 AVC creeeaza confuzia ca DVB-S2 inseamna HDTV ceea ce este fals.

    DVB-S2 "impacheteaza" altfel semnalul si are o corectie de semnal mult mai buna. Astfel se pot transmite cam 30 % mai multe date decit cu sistemul DVB-S iar cu comprimarea AVC (H.264) pe un feed se pot trimite pina la 5 canale HDTV fata de 2 la DVB-S, iar programe "normale pina la 20 fata de 8. Dezavantajul noii tehnici e ca nu se poate nici un receiver "adapta" la DVB-S2 fiind problema hardware.
    19,2°E + 0,8°W => DM800 + DM520 + VuZero

    Avantajul unui om inteligent este ca poate face usor pe prostul, invers e ceva mai dificil.....
