H-16ATSC-IP 16 Off-Air ATSC 8VSB RF Tuners to IPTV Gateway

The Thor Broadcast H-16ATSC-IP is a professional off-air ATSC to IPTV gateway designed for the United States, Canada, Mexico, and other regions using the ATSC 8VSB broadcast television standard. It receives up to 16 off-air ATSC RF channels from antenna coax inputs and converts the selected TV programs into IPTV streams for distribution over a local Ethernet network.

This model is used when you want to take free over-the-air broadcast TV channels from an antenna system and distribute them as IPTV throughout a building, campus, hotel, school, hospital, church, sports facility, or private network. Instead of running coax to every TV location, the H-16ATSC-IP receives the RF channels at the headend, tunes the selected ATSC frequencies, extracts the programs, and outputs them as UDP/RTP multicast or unicast IP streams.

Important Model Clarification

The H-16ATSC-IP is the correct model for ATSC 8VSB off-air antenna input. This is different from the H-16QAM-IP, which is used for cable QAM / DVB-C type RF signals. The tuner hardware is model dependent, so the correct version must be ordered based on the RF standard:

• H-16ATSC-IP - 16 off-air ATSC 8VSB RF tuners to IPTV
• H-16QAM-IP - 16 cable QAM RF tuners to IPTV
• H-16DVBS-IP - 16 satellite DVB-S / DVB-S2 RF tuners to IPTV

How the H-16ATSC-IP Works

The system starts with an off-air TV antenna. The antenna receives local broadcast TV channels using the ATSC 8VSB standard. The antenna signal is distributed through coax cable, usually through an RF splitter, amplifier, or MATV distribution system, and then connected to the 16 F-type RF inputs on the H-16ATSC-IP.

Each RF input feeds an internal tuner. Each tuner can be set to receive a specific off-air ATSC channel. After the tuner locks to the selected 8VSB RF channel, the gateway scans the transport stream and detects the available TV programs, including main channels and subchannels. For example, one RF channel may contain several programs such as 5.1, 5.2, 5.3, and 5.4.

The selected programs are then converted into IPTV streams. The unit can output the programs as SPTS single program transport streams or MPTS multiple program transport streams, depending on the system design. The IPTV output is sent through the DATA1 Ethernet port to a Gigabit Ethernet switch.

Typical Signal Flow

1. Off-air antenna receives local ATSC 8VSB TV channels.
2. The antenna RF signal is distributed by coax to the 16 RF tuner inputs.
3. The H-16ATSC-IP tunes selected ATSC RF channels.
4. The gateway detects the available TV programs and subchannels.
5. Selected programs are converted to UDP/RTP IPTV streams.
6. The IPTV streams output from the DATA1 Ethernet port.
7. A Gigabit Ethernet switch distributes the IPTV streams to STBs, IPTV decoders, or compatible video systems.

RF Input and Loop Output Explanation

The rear F-type connectors are the ATSC RF inputs. These inputs are used for coax feeds coming from an off-air antenna system. In many installations, the antenna feed is split and balanced before entering the gateway so each tuner receives proper RF level.

The unit may also provide RF loop outputs depending on the rear-panel configuration. A loop output passes the same RF antenna signal through to another RF device, such as a monitoring receiver, TV tuner, or second gateway. This can be useful when the same antenna RF feed needs to continue to additional equipment.

Important: the RF loop output is not an IP output. It is still an RF coax signal. The IPTV output comes from the Ethernet DATA port. The RF input and loop output are used only for antenna RF signal routing.

Why Use ATSC to IPTV?

The H-16ATSC-IP is ideal when a building already receives strong local off-air TV channels and wants to distribute those channels over an IP network. This allows the system designer to move from traditional coax-only TV distribution to a more flexible IPTV architecture.

With multicast IPTV, one channel stream can be distributed to many viewing locations without needing a separate RF tuner or satellite/cable receiver at every display. This makes the system easier to manage and better suited for large facilities.

Simple Explanation

The H-16ATSC-IP takes TV channels from an off-air antenna and turns them into IPTV streams. The antenna signal enters the unit through the 16 coax RF inputs. Each internal tuner receives an ATSC 8VSB channel, finds the available programs and subchannels, and converts them into network IP streams. Those IPTV streams leave the unit through the DATA1 Ethernet port and are distributed through a Gigabit Ethernet switch to IPTV set-top boxes, decoders, middleware systems, or compatible IP video players.
