FAQ
Q: Can the HDMI input ISDB-T RF output encoder be used in Japan?
A: da. The 1907 suporturi MPEG-2 video encoding, required by Japan’s ISDB-T system, și H.264, used by Brazilian ISDB-Tb. This makes it compatible with both standards.
Q: Can the HDMI to ISDB-T video encoder converter box be used for long-distance coaxial transmission?
A: da. Cu 100 dBμV RF output, it ensures stable HD signal transmission over long coaxial runs without additional amplification.
Q: Can it be used in DVB-T systems?
A: Nu. it is designed specifically for ISDB-Tb and ISDB-T systems. Use a DVB-T compatible modulator for DVB-T.
Q: How many channels can I set?
A: Pâna la 72 canale using DIP switch configuration.
Q: Aveți un codificator/modulator de 6M de ieșire ISDB-T de intrare SDI?
Bună, căutăm să cumpărăm un codificator/modulator ISDB-T pentru Argentina (6mhz), Poate canale VHF sau UHF. Dacă putem alege, preferăm intrarea video HD-SDI.
Răspuns: da, vă rugăm să verificați modelul de mai jos.
