Klausimas: Can the HDMI input ISDB-T RF output encoder be used in Japan?
A: Taip. The 1907 palaiko MPEG-2 video encoding, required by Japan’s ISDB-T system, ir H.264, used by Brazilian ISDB-Tb. This makes it compatible with both standards.
Klausimas: Can the HDMI to ISDB-T video encoder converter box be used for long-distance coaxial transmission?
A: Taip. Su 100 dBμV RF output, it ensures stable HD signal transmission over long coaxial runs without additional amplification.
Klausimas: Can it be used in DVB-T systems?
A: Ne. it is designed specifically for ISDB-Tb and ISDB-T systems. Use a DVB-T compatible modulator for DVB-T.
Klausimas: How many channels can I set?
A: Iki 72 kanalai using DIP switch configuration.
Klausimas: Ar turite SDI įvesties ISDB-T išvesties 6M kodavimo/moduliatoriaus?
Sveiki!, Mes norime nusipirkti keletą kodavimo/moduliatorių ISDB-T Argentinoje (6mhz), Gal VHF ar UHF kanalai. Jei galime pasirinkti, Mums labiau patinka HD-SDI vaizdo įrašas.
Atsakymas: Taip, Patikrinkite žemiau pateiktą modelį.
