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. Key Features Supports HDMI input up to 1080p resolution DIP switch channel setting, easy configuration up to 72 channels Stable RF output level of 100 dBμV for long-distance coax transmission Typical MER ≥ 35 dB ensures excellent modulation quality Small, lightweight, and wall-mountable (70×66×27 mm, 130 g) Quick installation – ready to link in minutes Ideal for HD image distribution, adding channels to TV systems, and monitoring applications Supports both H.264 and MPEG-2 video encoding, compatible with Brazil ISDB-Tb and Japan ISDB-T Specifications Video Encoding Parameter Specification Encoding H.264/MPEG-4 AVC (default), MPEG-2 supported Input Interface HDMI ×1 Supported Resolutions Input: 720@50/60p, 1080@50/60i/p, Output: max 1080@30p System PAL/NTSC Audio Encoding Parameter Specification Encoding AAC Sample Rate 48 kHz Modulator Section Parameter Specification RF Range 177.143 – 857.143 MHz (ISDB-T) RF Output Level 100 dBμV Modulation Quality MER Typ. 35 dB Channels Up to 72 via DIP switch Bandwidth 6 MHz General Parameter Specification Power Supply DC 12V 1A Dimensions 70×66×27 mm Weight 130 g Package Includes V2020I Modulator ×1 Power Supply ×1 Service Card ×1 Applications Monitor security cameras on domestic or communal TV systems Distribute HD images for hotels, schools, and corporate buildings Add extra channels to multi-dwelling or CATV TV systems Digital signage and information channels in public spaces 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. https://isdb-t.com/wp-content/uploads/2023/10/SDI-ISDB-T-User-Manual.pdf Q: Hi. Is there a firmware solution for VCAN1907 for low latency? The audio channel isn’t needed, only video transmission. hdmi video to DVB-T RF converter board A: Sorry, the VCAN1907 does not have a firmware option to reduce latency. If you need a low-latency solution for professional video transmission, please consider our professional COFDM models:�� Modulator Demodulator Module Encoder Decoder HDMI/CVBS
