שאלות נפוצות
ש: Can the HDMI input ISDB-T RF output encoder be used in Japan?
א: כן. ה 1907 תומך MPEG-2 video encoding, required by Japan’s ISDB-T system, ו H.264, used by Brazilian ISDB-Tb. This makes it compatible with both standards.
ש: Can the HDMI to ISDB-T video encoder converter box be used for long-distance coaxial transmission?
א: כן. עִם 100 dBμV RF output, it ensures stable HD signal transmission over long coaxial runs without additional amplification.
ש: Can it be used in DVB-T systems?
א: לא. it is designed specifically for ISDB-Tb and ISDB-T systems. Use a DVB-T compatible modulator for DVB-T.
ש: How many channels can I set?
א: עד 72 ערוצים using DIP switch configuration.
ש: Do you have an SDI input ISDB-T output 6M encoder/modulator?
היי, we are looking to buy some encoder/modulator ISDB-T for Argentina (6mhz), Maybe VHF or UHF channels. If we can choose, we prefer HD-SDI video input.
תשובה: כן, please check the below model.

The MJZSEE V2020I Encoder Modulator is an engineering marvel for modernizing legacy TV systems! Its ability to convert HDMI signals into ISDB-T RF output over existing coaxial cables is pure genius – we seamlessly distributed 4K content from our media player to every TV in our hotel without costly rewiring. The plug-and-play setup took minutes, and the signal stability is flawless, with zero latency or quality loss across 100+ rooms. Despite 24/7 operation, it runs cool and silent. This device single-handedly saved us thousands in infrastructure upgrades while delivering broadcast-grade HD quality. An absolute must-have for hotels, schools, or broadcasters bridging analog and digital worlds!
