FAQ
F: Can the HDMI input ISDB-T RF output encoder be used in Japan?
A: Ja. De 1907 stödjer MPEG-2 video encoding, required by Japan’s ISDB-T system, och H.264, used by Brazilian ISDB-Tb. This makes it compatible with both standards.
F: Can the HDMI to ISDB-T video encoder converter box be used for long-distance coaxial transmission?
A: Ja. Med 100 dBμV RF output, it ensures stable HD signal transmission over long coaxial runs without additional amplification.
F: Can it be used in DVB-T systems?
A: Nej. it is designed specifically for ISDB-Tb and ISDB-T systems. Use a DVB-T compatible modulator for DVB-T.
F: How many channels can I set?
A: Fram till 72 kanaler using DIP switch configuration.
F: Har du en SDI-ingång ISDB-T-utgång 6M kodare/modulator?
Hej, Vi vill köpa en del kodare/modulator ISDB-T för Argentina (6mhz), Kanske VHF- eller UHF -kanaler. Om vi kan välja, Vi föredrar HD-SDI-videoinmatning.
