概述

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 和 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.

主要特征

• 支持 HDMI input up to 1080p resolution

• DIP switch channel setting, easy configuration up to 72 频道

• Stable RF output level of 100 分贝μV for long-distance coax transmission

• 典型的 MER ≥ 35 D b ensures excellent modulation quality

• 小的, 轻的, 和 wall-mountable (70×66×27 mm, 130 G)

• Quick installation – ready to link in minutes

• 非常适合 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

常问问题

问: Can the HDMI input ISDB-T RF output encoder be used in Japan?
一种: 是. 这 1907 支持 MPEG-2 video encoding, required by Japan’s ISDB-T system, 和 H.264, used by Brazilian ISDB-Tb. This makes it compatible with both standards.

问: Can the HDMI to ISDB-T video encoder converter box be used for long-distance coaxial transmission?
一种: 是. 和 100 dBμV RF output, it ensures stable HD signal transmission over long coaxial runs without additional amplification.

问: Can it be used in DVB-T systems?
一种: 不. it is designed specifically for ISDB-Tb and ISDB-T systems. Use a DVB-T compatible modulator for DVB-T.

问: How many channels can I set?
一种: 取决于 72 频道 using DIP switch configuration.

一种: 抱歉, 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:
