Thor Broadcast 16-Channel ATSC-IP Gateway (H-16ATSC-IP) View product page
Designed for ATSC off-air to IP conversion with direct MPEG-TS pass-through (no re-encoding).
A customer needed measurable, professional-grade, sub-1-second latency for live off-air channels (ABC, CBS, NBC) delivered across an Ethernet-only LAN. Consumer-grade approaches produced ~2 seconds delay and inconsistent behavior.
Final result: broadcast-grade delivery with typically < 500ms latency using a 16-channel ATSC to IP gateway.
Many organizations (universities, K-12 schools, government agencies, stadiums, emergency-response centers, and enterprise campuses) need to distribute live free-to-air TV internally, but have no coax infrastructure. Instead, they rely entirely on RJ45 Ethernet cabling.
As expectations for digital TV and latency become more demanding, legacy consumer devices often cannot deliver consistent, measurable low-latency results.
This scenario involved a customer named Mic who required sub-1-second live video latency across a LAN. After testing consumer hardware plus streaming software, the delay remained too high (~2 seconds).
The requirement was clear: professional-grade ATSC-to-IP conversion with reliable, ultra-low latency.
These requirements eliminated most consumer equipment: typical consumer workflows re-encode content and introduce buffering, delay, and variable behavior under load.
"How can we watch free ATSC antenna channels on PCs using only our RJ45 Ethernet network?"
A dedicated ATSC to IP gateway is the correct approach:
Although the consumer approach "worked," it did not deliver the consistency, low latency, and operational reliability needed for professional deployment. Re-encoding and buffering add delay, while software-based redistribution adds complexity and failure points.
Thor Broadcast recommended the H-16ATSC-IP (16-channel ATSC to IP gateway): a commercial-grade device designed for off-air ATSC to IP conversion with direct MPEG-TS pass-through and measurable ultra-low latency.
No coax drops, no set-top boxes, no re-encoding, and extremely low latency across a standard Ethernet network.
Deployment concept:
Result: Ethernet-only TV distribution with measurable low latency and professional reliability.
Organizations increasingly search for solutions like:
This reflects a broader shift from coax-based distribution to IPTV over Ethernet in modern facilities.
Mic's situation is common: deliver reliable off-air TV channels across an Ethernet-only network with truly low latency. Consumer tools introduced too much delay and could not guarantee consistent performance at scale.
The Thor Broadcast 16-channel ATSC-IP gateway provided a professional-grade answer for IPTV over LAN without coax.
