8 Channel RF to IP Gateway - ATSC, QAM, DVB-S/S2, DVB-T/T2, and ISDB-T to IPTV

Professional 8 Frequency RF to IPTV Gateway

The Thor Broadcast 8 Channel RF to IP Gateway is a professional headend device designed to receive up to 8 RF frequencies and convert the TV programs inside those frequencies into IPTV streams for distribution over a LAN network. Depending on the selected model, the unit can receive ATSC off-air antenna signals, clear QAM cable channels, DVB-S/S2 satellite signals, DVB-T/T2 terrestrial antenna signals, or ISDB-T terrestrial broadcasts.

This product family is ideal for converting existing RF broadcast signals into IPTV multicast or unicast streams. It allows local antenna channels, cable TV channels, satellite transponders, or international terrestrial TV broadcasts to be delivered to IPTV set-top boxes, smart TV decoders, computers, tablets, digital signage players, and other IP video devices.

Available Input Modulation Models

How the RF to IP Gateway Works

Digital RF broadcast systems can carry multiple TV programs inside one RF frequency. For example, one ATSC 8VSB antenna channel may include several sub-channels such as 2.1, 2.2, 2.3, and 2.4. A clear QAM cable channel can also contain multiple programs inside one 6 MHz RF carrier. DVB-S/S2 satellite transponders and DVB-T/T2 multiplexes can also carry multiple TV or radio services in one RF signal.

The Thor 8 Channel RF to IP Gateway tunes up to 8 RF frequencies, demodulates the selected signals, identifies the available TV services, and converts those services into IP transport streams. The output can be configured as SPTS for individual program streams or MPTS for multiplexed transport stream output, depending on the system design.

IPTV Output Over LAN

The gateway outputs IPTV streams over Ethernet using standard transport stream protocols such as UDP, RTP, and RTSP. The IP output can be configured for multicast when many devices need to watch the same channels, or unicast for direct point-to-point streaming.

• Converts up to 8 RF frequencies to IPTV streams
• Supports SPTS and MPTS output modes
• Outputs IPTV streams over UDP, RTP, or RTSP
• Supports multicast or unicast IP delivery
• Can output multiple TV services from each tuned RF channel
• Designed for professional RF, IPTV, and broadcast headend systems

Important Gateway Note: No Video Re-Encoding

This unit works as an RF to IP gateway. It does not re-encode or transcode the video. The video and audio format received from the RF signal is passed through to the IP output. For example, if the incoming QAM or ATSC program is MPEG-2, the IP stream will remain MPEG-2. If the incoming program is H.264, the IP output will remain H.264.

This gateway design helps preserve original broadcast quality, reduce processing delay, and simplify system integration. The receiving IPTV decoder, set-top box, player, or software must support the video and audio format contained in the original RF broadcast stream.

ASI Input and ASI Output for Broadcast Headends

In addition to IP streaming, the unit includes ASI input and ASI output for professional broadcast integration. The gateway can multiplex tuned RF services and ASI input content into a transport stream output. This makes it useful in CATV headends, IPTV systems, monitoring racks, broadcast facilities, and hybrid RF/IP distribution systems.

Typical Applications

• Off-air antenna TV to IPTV conversion
• Clear QAM cable channels to IPTV streams
• Satellite DVB-S/S2 transponders to IP network distribution
• DVB-T/T2 terrestrial broadcast channels to IPTV
• ISDB-T terrestrial channels to IP streaming
• Hotel, hospital, campus, school, government, and enterprise IPTV systems
• Private cable TV headends and MATV systems
• Broadcast monitoring over LAN
• Digital signage and IP video distribution
• Adding local RF channels to an existing IPTV lineup

RF to IP Gateway + Optional RF Transmodulator Versions

Some versions of this platform are also available as an RF to IP Gateway plus RF Transmodulator. These versions can receive RF signals, create IPTV streams, and also output new RF channels at the same time. This is useful when a system needs both IP distribution and RF channel conversion.

For example, the unit can receive ATSC antenna channels and output them as IPTV streams while also converting them to QAM RF channels for a cable TV style coax distribution system. It can also be used to rearrange or translate existing RF channels in a headend, depending on the selected input and output modulation options.

Optional Transmodulator Examples

RF Input and RF Output Compatibility

Standard RF to IP models are selected by the required RF input type. Optional transmodulator versions can be configured with different RF output formats, depending on the project requirements.

• Available RF Input Types: ATSC 8VSB, Clear QAM, DVB-S/S2, DVB-T/T2, ISDB-T
• Available RF Output Types on Transmodulator Versions: ATSC, QAM, DVB-T/T2, ISDB-T
• IP Output: UDP, RTP, RTSP, multicast or unicast
• ASI: ASI input and ASI output for professional transport stream integration

Web Browser Management

The unit includes network-based control for setup and monitoring. Operators can scan input frequencies, view available services, select programs, configure IP stream addresses, manage SPTS or MPTS output, and monitor system status from a web browser.

Summary

The Thor Broadcast 8 Channel RF to IP Gateway family provides a flexible way to convert existing RF television signals into IPTV streams. With model options for ATSC, clear QAM, DVB-S/S2, DVB-T/T2, and ISDB-T, the same platform can be used in North American, European, African, Latin American, Asian, satellite, cable, and private headend systems. It is a reliable solution for moving broadcast RF channels into modern IP video distribution while maintaining professional headend features such as ASI integration, SPTS/MPTS control, multicast streaming, and browser-based management.
