The INFINIUM 4K30 Encoder Card accepts HDMI 2.0b 18 Gbps sources up to 4K@30 4:4:4 and encodes them in HEVC, H.264, or MJPEG. It is the cost-effective way to add a true Ultra-HD channel to your headend for IPTV, web streaming, and — with the 4K-over-coax module — real 4K TV channels over existing coax.
4K Encoder Card
True 4K Ultra-HD, Encoded with Confidence
Bring 4K@30 to the INFINIUM chassis from any HDMI 2.0b source. HEVC encoding saves up to four times the bandwidth, so your 4K reaches a far larger audience on the same connection.
Capabilities
4K Everywhere Your Audience Watches
Encode once and deliver to players, set-top boxes, smart TVs, browsers, and global platforms — all at the same time, each in the right format.
- Four simultaneous streams — different compression & resolution each, with logos & watermarks
- SRT ultra-low latency down to 50 ms · RTMP, M3U8, HLS, HTTP, UDP, RTP, RTSP, ONVIF
- Built-in 1 Gb unicast server — hundreds of concurrent viewers; multicast to unlimited
- Stream direct to YouTube, AWS, or Facebook — and to several platforms at once
- Auto-reconnect and SRT decoder compatibility (VLC and our VePlayer)
IP + Coax
4K Over IP — and Over Coax
Stream 4K across your network and the internet, and pair with the INFINIUM 4K-over-coax module to deliver real 4K channels to ordinary TVs over the coaxial cables already in your building.
The 4K30 card streams Ultra-HD to any IP destination, and when the chassis includes the 4K-over-coax module, the same channel is delivered over existing coax to an unlimited number of 4K televisions — no set-top boxes, no new wiring. One card, every audience.

FAQ
INFINIUM 4K30 Card — FAQ
What resolution does the 4K30 card encode?
It accepts HDMI 2.0b sources up to 4K@30 4:4:4 (18 Gbps) and encodes true Ultra-HD in HEVC, H.264, or MJPEG. For 4K at 60 fps or SDI input, choose the 4K60 broadcast card.
Why choose HEVC over H.264 for 4K?
HEVC (H.265) delivers the same picture quality at roughly one-quarter the bitrate of H.264. For 4K that means far less network and internet bandwidth, letting you reach more viewers or run more channels on the same connection.
Can it stream to multiple destinations at once?
Yes — up to 4 simultaneous streams, each with its own compression, resolution, bitrate, and protocol. Send a high-quality 4K stream to a video wall and a lighter stream to mobile devices at the same time.
Does it support SRT?
Yes. SRT ultra-low-latency (down to 50 ms plus network travel time) is built in, alongside RTMP(S), HLS, HTTP, RTSP, RTP, FLV, ONVIF, and UDP/RTP unicast and multicast.
How many viewers can it serve directly?
The built-in 1 Gb unicast server supports hundreds of concurrent viewers depending on bitrate. For unlimited audiences, send one stream to YouTube, AWS, or any platform, or use multicast for unlimited devices on a capable network.
Can I distribute this 4K channel over coax?
Yes — add the INFINIUM 4K-over-coax RF module to the chassis and the 4K30 channel is delivered as a real digital TV channel over existing coax to any 4K television, with no set-top box.
Does it require the INFINIUM chassis?
Yes. The 4K30 card installs in the INFINIUM 4K Video Distribution Chassis, which supplies power, cooling, redundancy, and the network/RF backplane.
