IPTV technology guide
An IPTV encoder turns a video source, such as a camera, a receiver or a computer, into a compressed stream that travels over an IP network. Here are popular encoders that hotels, broadcasters, churches and live-event teams rely on, what each one does best, and how to choose.
Video straight from a camera or an HDMI port is far too large to send over a network. An IPTV encoder does two jobs: it compresses the video with a codec such as H.264 or H.265, and it packages the result for a network protocol such as UDP multicast, SRT or RTMP.
Encoders come as hardware boxes, as software on a computer, or as a cloud service. Hardware is usually the most reliable for 24/7 channels; software is the cheapest way to start; cloud encoding scales without any equipment on site. The right one depends on how many channels you need and where the stream is going.
The encoders below are listed by type. All details come from each maker's own specifications.

Hotels, hospitals, stadiums, campuses and offices use these to turn TV sources into channels that every screen on the network can tune to. They usually send UDP multicast inside the building rather than streaming to the internet.
Best for: Building-wide TV channel line-ups
A two-channel IPTV encoder built for in-building TV systems. Each unit takes two HDMI sources and turns them into two separate IPTV channels that TVs and set-top boxes on the network can tune to. Units mount two across, so four channels fit in one rack space.
Best for: Many channels in one chassis
A high-density, multi-channel H.264 encoder. One chassis takes 4, 8, 16 or 24 HDMI sources and outputs each as its own IPTV stream, ready for a headend or a TV distribution network.
Best for: Small setups on a budget
A compact single-input encoder that streams one HDMI source in H.265 or H.264 at up to 1080p60. It can multicast to screens on a local network or push to platforms such as YouTube, and its HDMI loop-out keeps a local screen connected.
Broadcasters, live-event crews, churches and sports venues use these to send high-quality live feeds over the internet or to a platform, with low delay and protection against packet loss.
Best for: Broadcast contribution and 4K live events
A common choice for broadcasters sending live feeds from venues back to the studio. It encodes one 4K UHD signal or up to four HD signals in HEVC or H.264 with 10-bit 4:2:2 colour, and sends them over SRT, the open-source transport protocol Haivision created.
Best for: Multi-camera remote production
Built for remote production: it encodes up to four synchronised HD cameras, or one 4Kp60 feed, as 10-bit 4:2:2 H.264 and sends them to the studio. It can record while it streams.
Best for: Mixed workflows that need NDI
A dual-input (HDMI and 3G-SDI) HEVC encoder that streams both inputs separately or combines them picture-in-picture. It supports almost every protocol in use today, from NDI HX for studios to plain TS over UDP for IPTV networks.
Best for: One source to many destinations
A compact encoder that sends one HDMI source to several destinations at the same time in H.264 or H.265, over nearly every protocol a streaming or IPTV setup needs.
Best for: Streaming and recording together
AJA's streamer/recorder takes SDI or HDMI in and has two H.264 encoders, so it can send two differently sized streams while recording to an SD card, USB drive or network storage.
Best for: Affordable 4K streaming from SDI
Blackmagic's 4K streaming box, from the product line formerly called Web Presenter. It takes an SDI source up to 2160p60 and streams it over RTMP in H.264, or over SRT in H.264 or H.265, with a built-in screen and controls.
Software turns a computer into an encoder. It's the cheapest way to start, and the most flexible, as long as the computer is powerful and reliable enough.
Best for: Free streaming from a computer
The free, open-source streaming app for Windows, macOS and Linux. It encodes with the CPU (x264) or with the graphics card's hardware encoder, and streams over RTMP, SRT or WHIP (WebRTC).
Best for: Scripted and server-side encoding
The free command-line toolkit that many IPTV panels, media servers and transcoders use under the hood. It can read almost any input, encode H.264, H.265 or AV1, and write multicast UDP, SRT or HLS, all from a script.
Best for: Live production on Windows
Windows live-production software (switching, graphics and replays) with built-in encoding. Every edition can send and receive SRT, in H.264 or HEVC, alongside standard RTMP streaming.
Cloud services encode in a data center, so you can add channels without buying or racking hardware.
Best for: Scaling channels without hardware
Amazon's managed live-encoding service. You send it a feed, for example over SRT, and it encodes H.264, H.265 or MPEG-2 (and AV1 for some outputs) into HLS and other formats, running in AWS data centers.
Answer these six questions and the shortlist usually picks itself.
The codec decides how much bandwidth a channel needs and which screens can play it. Newer codecs save bandwidth; older ones play everywhere.
| Codec | Plays on | Bandwidth | Best for |
|---|---|---|---|
| H.264 (AVC) | Plays on almost every TV, box and phone | The baseline | Maximum compatibility, older set-top boxes |
| H.265 (HEVC) | Most TVs and boxes from the last few years | Up to about half the bitrate of H.264 | 4K and limited bandwidth |
| AV1 | Newer devices and browsers | Similar to or better than HEVC | Internet streaming to modern devices |
| MPEG-2 | Older hotel and cable systems | Needs the most bandwidth | Keeping legacy TV systems running |
The protocol decides how the stream travels. Most encoders support several at once.
There's no single winner; it depends on the job. OBS Studio and FFmpeg are among the most widely used software encoders because they're free. In broadcast, Haivision Makito and Matrox Monarch encoders are common choices, and in-building TV systems often use multi-channel HDMI encoders. H.264 is still the most widely used codec.
No. Encoders are for people who create streams. To watch an IPTV service such as IPTV Trends you only need a player app on your TV, stick, phone or computer and an internet connection.
H.265 (HEVC) gives the same picture at up to about half the bitrate, which matters for 4K and slower connections. But every screen must be able to decode it. If you have older set-top boxes, H.264 is the safer choice.
An encoder compresses raw video from a source such as HDMI or SDI. A transcoder takes a stream that's already compressed and converts it to another codec, bitrate or format, for example to make several quality levels for adaptive streaming.
Technically yes: a single-channel HDMI encoder can multicast one source to other screens on your network. But most cable and satellite boxes protect their HDMI output with HDCP, which encoders won't capture, and your TV provider's terms may not allow it.
