This HD-IN extender over a coaxial cable can do digital coding processing from HD-MI signal with DTV technology.
The product adopts RF modulation technology characteristics to transmit multiple RF signals through one
standard coaxial cable for long-distance transmission without amplification.
The receiver can restore the high-definition video signal and transmit it to the TV or monitor.
Overview
The HDMI to ISDB-T video encoder converter box is a compact ISDB-T Digital Encoder Modulator that converts HDMI input signals into digital RF channels for coaxial transmission. Designed for ISDB-Tb in Brazil and ISDB-T in Japan, it supports up to 1080p HD video with H.264/MPEG-4 AVC by default, and also supports MPEG-2 encoding, ensuring full compatibility across both regions.
The V2020I is ideal for distributing HD video over existing coaxial networks without additional amplification, making it perfect for hotels, multi-dwelling buildings, corporate TV systems, or security monitoring setups.

FAQ
Q: Can the HDMI input ISDB-T RF output encoder be used in Japan?
A: Yes. The 1907 supports MPEG-2 video encoding, required by Japan’s ISDB-T system, and 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: Yes. 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: No. 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: Up to 72 channels using DIP switch configuration.
Q: Do you have an SDI input ISDB-T output 6M encoder/modulator?
Hi, 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.
Answer: Yes, please check the below model.
