Anttron TM190HD HDMI to DVB-T COFDM Modulator – RF Mix Input, USB Record & 40 dB MER

The Anttron TM190HD converts an HDMI signal — from any source at standard resolutions — into a DVB-T RF output that can be injected into an existing terrestrial or cable coaxial network. The module accepts one HDMI input and one RF mix input, combining them at the RF output. A USB stick is included for recording and playback directly from the unit.

Designed for professional headend installations, the TM190HD delivers a modulation error rate of 40 dB, on a par with premium headend equipment, while drawing only 5 W.

Key Features

• 1 HDMI input capable of receiving all standard resolutions
• 1 RF mix input (F female, 5–1002 MHz) to pass through existing terrestrial or cable signals
• 1 RF output combining the HDMI-derived DVB-T channel with the signals from the RF input
• COFDM standard: DVB-T output with selectable 7/8 MHz channel bandwidth
• Carrier modulation: QPSK, 16QAM, 64QAM (optional)
• FEC options: 1/2, 2/3, 3/4, 5/6, 7/8
• USB record and play function (USB stick included)

Product Benefits

• Adds any HDMI source to a coaxial TV distribution network without rewiring
