Q: Can the HDMI input ISDB-T RF output encoder be used in Japan?
A: Jah. The 1907 supports MPEG-2 video encoding, required by Japan’s ISDB-T system, ja 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: Jah. With 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: Ei. 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: Kuni 72 kanalid using DIP switch configuration.
Q: Kas teil on SDI sisend ISDB-T väljund 6M kodeerija/modulaator?
Tere, Soovime osta Argentina jaoks kodeerijat/modulaatorit ISDB-T (6mhz), Võib-olla VHF või UHF kanalid. Kui saame valida, eelistame HD-SDI videosisendit.
Vastus: Jah, kontrollige allolevat mudelit.

ISDB-T.com_Buyer –
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!
