4 HDMI model description

Thor 4 HDMI Digital RF Modulator is an all-in-one device integrating MPEG2 encoding and modulating to convert audio video signals into DVB-C T ATSC ISDB-T RF out.

Description

The 4-channel Thor Thunder-4 HDMI RF Modulator is a powerful device designed to encode and modulate HDMI sources into CATV RF channels. It supports Full HD resolutions up to 1080p/60 and enables seamless distribution of content over coaxial cables to multiple TVs equipped with QAM or ATSC tuners. This makes it an excellent choice for cost-effective video distribution in environments like hotels, schools, and residential setups.

Once connected to a coaxial network, the modulator allows TVs to scan and locate the channels easily. Users can then switch between channels using a standard TV remote, simplifying content delivery and management. The unit encodes video in MPEG-2 format and audio in either AC3 or MPEG1, ensuring compatibility with a wide range of devices.

The Thunder-8 is designed for user-friendly operation, offering two convenient control options:

Web-based GUI accessible via IP interface.
Front-panel LCD display with physical buttons for on-site configuration.

Notably, the modulator is HDCP-compliant, meaning it works seamlessly with any HDMI source, including encrypted content.

For larger installations, multiple Thunder units (or a combination of Thunder-4 and Thunder-8 models) can be connected together to create up to 135 CATV RF channels. The 8-channel model is available under the part number Thunder-8, making it a versatile and scalable solution for high-density video distribution.

Additionally, this unit can generate any worldwide CATV RF modulation standard, including ATSC, DVB-C Annex A, DVB-C Annex B, DVB-T, and ISDB-T, ensuring global compatibility and flexibility for any application.

H- THUNDER-4 Supports 4 HDMI inputs and its modular design (maximum 4 HDMI inputs) and flexible configuration makes it scalable and very reliable while providing high performance.

The signal source could be from any STB, satellite receiver, closed-circuit television cameras, and antenna, etc. Its output signal is designed to work with any TV or STB. Because it comes standard with every RF modulation standard builtin, this device can work anywhere in the world in a plug and play format.

This unit is similar to our popular line H-1,2,4 HDMI-QAM-IPLL product line, but it has some differences. It is a less expensive unit, each program is modulated on its own frequency, CATV RF output only, no IPTV output

Economical 4 HDMI Digital Modulator RF CATV over Coax QAM ATSC DVB T ISDBT Included Thor B

This video shows some of the detailed functionality of the new Thor 4 channel digital modulator in full HD. The Thor Thunder-4 modulator is the easiest way to distribute HD content to an unlimited amount of TV's or monitors using an existing coaxial RF network. This modulator is unique because it can produce 4 separate CATV channels in any RF modulation format simultaneously, those channels can be set individually and do not have to be adjacent, so you can set it up on channels 10/21/32/45 without any issue. It supports ATSC, QAM Annex B and A, DVB-T, and ISDB-T. One modulator can distribute Video to unlimited TV's using RF amplifiers, taps, splitters etc so long as your RF network supports it. The Thunder-4 is HDCP compliant and supports, VCT -Virtual channel numbers and names. Supports SD and HD video resolutions : 480i,720p,1080iand 1080p/60hz input resolution. By far the best value for a 4 channel modulator with accessible built-in options, warranty, and Thor Support to help make sure your project or application installation goes perfectly the first time.
