The Anttron TMX170HD is a compact HDMI-to-DVB-T/C modulator that allows any HDMI-equipped device — such as a Blu-ray player, gaming console or streaming box — to be watched on every TV in a building via the existing coaxial cable infrastructure. The output channel appears alongside regular digital terrestrial channels in the TV's channel list, with resolutions up to 1080p.

An HDMI loop output keeps the source signal available for a directly connected display at the same time. The device is controlled through a 3-button menu with a 2×16 character LCD, and includes RF Bypass so the coaxial network continues to carry other channels uninterrupted.

Key Features

• Converts HDMI input to DVB-T or DVB-C RF output, ready for distribution over coaxial cable
• Supports resolutions up to 1080p (480p, 576p, 720p, 1080i, 1080p)
• HDMI loop output keeps the source connected to a local display simultaneously
• RF Bypass for uninterrupted pass-through of existing coaxial signals
• 3-button control with 2×16 character LCD for on-device configuration
• Full SI table insertion: PAT, PMT, SDT, NIT
• Configurable channel/network name, SID, LCN, TSID, ONID, NID, audio and video PIDs

Product Benefits
