The PVI INFINIUM 4K is our flagship video-distribution platform — the same engine recognized with NAB 2020 and InfoComm 2020 Best of Show awards. It replaces racks of single-purpose appliances with one 4RU chassis that you populate to fit the job: load up to 14 hot-swappable encoder cards, add the optional 4K-over-coax RF module, and broadcast everywhere your audience watches. Start with a few channels and grow to a full headend without ever changing platforms.
Flagship Platform
4K Over Everything — One Modular Headend
Distribute any HD or 4K source to smart TVs, phones, browsers, IPTV boxes, and ordinary coax televisions at the same time — from a single expandable chassis.
One Platform
One Chassis. Every Format. Anywhere.
The INFINIUM 4K converts your sources once and delivers them everywhere — over the internet, across your network, and over the coaxial cables already in your building. No separate encoders, gateways, and modulators to buy and wire together.
- Live IP streaming — SRT, RTMP, HLS, M3U8, UDP, RTP, RTSP, HTTP
- IPTV to smart TVs, set-top boxes, phones, tablets, and HTML5 browsers
- Optional 4K-over-coax RF module — real 4K channels to existing TVs
- Multiple compression formats and bitrates out per input — reach any device
- Mix HDMI and SDI sources, HD and 4K, in the same chassis
Always On Air
Hot-Swappable Cards, Power, and Fans
Service, replace, or expand any card while the rest of the system keeps broadcasting. With dual redundant power supplies and dual redundant fans, the INFINIUM never has to be powered down.
Every encoder card, both power supplies, and both cooling fans are independently hot-swappable from the front and rear panels. You can add a channel, swap a module, or replace a power supply on a live system without taking a single channel off the air. This fully redundant architecture is what makes the INFINIUM suitable for 24/7 broadcast, hospitality, and command-and-control environments where downtime is not an option.
Up to 4K@60 HDR+
Handles the Newest 4K Formats
INFINIUM 4K encoder cards accept the latest HDMI 2.0b 18 Gbps HDR+ and Dolby Vision sources and deliver full-quality 4K over IP and coax using our advanced HEVC and H.264 compression — so the picture on every display exceeds expectations.
- HDMI 2.0b 18 Gbps inputs — HDR+ and Dolby Vision ready
- Real 4K@60 encoding with HEVC (H.265) or H.264
- Full EDID control locks sources into maximum-quality mode
- 12G-SDI input option for broadcast 4K workflows
Still Need HD?
Every HD Format, Beautifully Compressed
Not everything is 4K. INFINIUM HD-only encoder cards — HDMI or 3G-SDI — deliver gorgeous HD at remarkably low bitrates, so you can pack more channels onto the same network or internet connection without sacrificing quality.
- HDMI and 3G-SDI HD encoder cards available
- Encodes 480p, 576p, 720p, 1080i, 1080p, and non-standard sources
- HDR-optimized HD motion estimation at the lowest bitrates
- Choose H.264 for compatibility or HEVC for maximum efficiency
Built-In Streaming Server
A Multi-Gigabit Unicast Server on Every Channel
Stream directly to thousands of viewers without a separate media server. Each channel has its own gigabit-class unicast server, and SRT keeps internet latency as low as 50 ms plus network travel time.
Streaming to smart TVs, phones, tablets, and HTML5 browsers requires a unicast server because every viewer is a unique on-demand connection. The INFINIUM builds one in for every channel, so a single chassis can serve thousands of simultaneous viewers across a gigabit network. Need a bigger audience? Send one stream per channel to YouTube, AWS, or any CDN to reach millions live. For SRT-capable players such as VLC and our VePlayer hardware decoders, the INFINIUM delivers ultra-low-latency performance ideal for live events, worship, corporate town halls, and remote learning.
Add 4K Over Coax
Upgrade Existing Coax to 4K@60 HDR+
Add the optional 4K RF modulator module — built on our award-winning VeCOAX technology — and deliver real 4K channels to an unlimited number of TVs over the coax already in your walls. No new cabling, splitters, or amplifiers required.
Where coaxial TV distribution is needed, the INFINIUM accepts a dedicated 4K-over-coax modulator module in its special slot. It delivers HD and full 4K@60 HDR+ channels over your existing coaxial infrastructure to any ordinary 4K television — no adapters or set-top boxes at each screen. IP streaming and coaxial distribution run at the same time from one modular unit, so you can serve online viewers and on-site TVs simultaneously. One platform, no limits.

FAQ
Frequently Asked Questions About the INFINIUM 4K
What is the INFINIUM 4K and what does it do?
The INFINIUM 4K is a modular 4RU video-distribution headend. You populate it with hot-swappable encoder cards and an optional 4K-over-coax RF module to distribute any HD or 4K source over live IP streaming, IPTV, and coaxial cable at the same time — to smart TVs, phones, browsers, IPTV boxes, and ordinary coax televisions.
How many channels can one INFINIUM chassis handle?
Up to 14 hot-swappable encoder cards fit in a single 4RU chassis, giving you up to 14 independent channels. A dedicated rear slot also accepts the 4K-over-coax RF modulator module when coax distribution is required.
What streaming protocols does the INFINIUM support?
Every modern protocol: SRT for ultra-low latency, plus RTMP, HLS, M3U8, UDP, RTP, RTSP, HTTP, and IPTV. Each channel can output multiple formats and bitrates at once so you can reach any player, set-top box, smart TV, or platform such as YouTube and AWS.
Can the INFINIUM send 4K over my existing coax to regular TVs?
Yes. Add the optional 4K-over-coax RF module — built on our award-winning VeCOAX technology — and the INFINIUM delivers real 4K@60 HDR+ channels over the coaxial cables already in your building to an unlimited number of 4K TVs. No new cabling, splitters, amplifiers, or set-top boxes are required.
What encoder cards are available?
A 4K60 HEVC card with HDMI 2.0b and 12G-SDI inputs, a 4K30 HEVC HDMI card, a 1080p HEVC HDMI card, a 1080p H.264 HDMI card, and a 3G-SDI HEVC HD card. You can mix any combination of HD and 4K, HDMI and SDI, H.264 and HEVC cards in the same chassis.
What does hot-swappable operation mean and why does it matter?
Every encoder card, both power supplies, and both fans can be removed and replaced while the system is running. You can service, replace, or add a channel without taking any other channel off the air — essential for 24/7 broadcast, hospitality, and command-and-control operations where downtime is unacceptable.
How many simultaneous viewers can the INFINIUM serve?
Each channel has its own built-in gigabit-class unicast server, so a single chassis can serve thousands of concurrent viewers over a gigabit network. For unlimited audiences, send one stream per channel to a platform such as YouTube Live or AWS to reach millions of people at once.
Does the INFINIUM support SRT ultra-low latency?
Yes. SRT is built in, delivering auto-error-corrected streaming as fast as 50 milliseconds plus the internet travel time. SRT-capable players such as VLC and our VePlayer hardware decoders receive the lowest-latency feed for live events, worship, sports, and corporate town halls.
What is the difference between the HD and 4K encoder cards?
4K cards accept HDMI 2.0b 18 Gbps HDR+ / Dolby Vision sources and encode real 4K (up to 4K@60 on the flagship card). HD cards encode 480p through 1080p from HDMI or 3G-SDI sources at very low bitrates. Use 4K cards for Ultra-HD content and HD cards to pack more standard-definition and HD channels onto the same network.
Can I mix HDMI and SDI sources in one chassis?
Yes. The INFINIUM is source-agnostic. Install HDMI encoder cards and 3G-SDI / 12G-SDI encoder cards side by side in the same chassis, mixing HD and 4K channels however your installation requires.
Do I need a computer to operate the INFINIUM?
No dedicated computer is required to run it. The INFINIUM is configured and monitored from a secure web browser on any operating system, and it generates an SNMP MIB file for integration with network monitoring systems.
What warranty and support does the INFINIUM include?
A 5-year (60-month) limited manufacturer warranty plus free unlimited technical support for the life of the product. The INFINIUM is designed, assembled, and supported in the USA by Pro Video Instruments.
