HDMI to DVB-T / ISDB-T H.264 Encoder Modulator 1080p
Overview
The Vcan1907 HDMI to DVB-T / ISDB-T Encoder Modulator is a compact and cost-effective digital TV encoding and RF modulation solution designed for professional video distribution.
It converts HDMI audio and video signals into DVB-T or ISDB-T digital television RF signals, allowing video content to be distributed through existing coaxial cable networks to compatible TVs and set-top boxes.
Featuring MPEG-4 AVC/H.264 video encoding, support for resolutions up to 1080p60, and Ethernet-based web management, this HDMI encoder modulator provides a practical solution for distributing high-quality video across multiple screens.
Whether you are building a hotel TV system, a surveillance monitoring network, a digital signage installation, or a ground-based video distribution system, the Vcan1907 offers flexible configuration and straightforward integration.
Key Features
- HDMI Input: Accepts digital audio and video from cameras, computers, media players, and other HDMI sources.
- H.264 Video Encoding: Uses MPEG-4 AVC/H.264 compression for efficient digital video transmission.

- 1080p60 Support: Handles supported input resolutions up to 1920 × 1080 at 60 Hz.
- Wide RF Frequency Range: Adjustable RF output frequency from 100 to 950 MHz in 1 kHz steps.
- Adjustable RF Output: Nominal output level of 100 dBμV with 30 dB adjustable attenuation.
- Web-Based Management: Configure device parameters through the Ethernet interface and Web NMS.
- Logical Channel Numbering: Supports LCN for digital TV channel organization.
- Compact Design: Small form factor for convenient installation in space-constrained systems.
- Firmware Upgrade: Supports firmware upgrades through Ethernet.
- Rack Integration: Supports installation of up to 14 units in a compatible 2U rack frame.
How It Works
The Vcan1907 converts an HDMI signal into a digital television RF channel in three steps:
- HDMI Input: Connect an HDMI source, such as a camera, computer, media player, or video receiver.
- Encoding and Modulation: The device encodes the video using H.264 and modulates the signal according to the selected DVB-T or ISDB-T standard.
- RF Output: Connect the RF output to a compatible coaxial distribution network. Compatible TVs or set-top boxes can then receive the configured digital TV channel.
This architecture allows one HDMI source to be distributed to multiple compatible receivers without requiring a separate HDMI cable for each display.
