Any IP stream on your network — from a VeCASTER or VeCODER encoder, a multicast headend, or any UDP/RTP source — becomes a real television channel. The IP-MOD 4X multiplexes up to 64 incoming programs onto four independent RF frequencies with full broadcast quality, from 50 to 1000 MHz across the entire VHF and UHF bands. No new wiring, no set-top boxes at the TVs, no software on the screens: just tune the channel.
Professional IP-to-Coax RF Modulator
IP Streams In. Perfect TV Channels Out.
The IP-MOD 4X receives up to 64 IP streams and converts them into 4 broadcast-quality RF channels that play on every TV in the building — over the coax you already own.
Full Remultiplexer
Cherry-Pick 64 Streams Into 4 Perfect Bouquets
Each of the four RF outputs has a fully-featured stream remultiplexer. Pick the programs you want, build the bouquet, and restamp names and numbers so the TV lineup looks exactly how you designed it.
- Receives up to 64 unicast or multicast IP streams (UDP/RTP) on a gigabit port
- 4 independent RF multiplexes — adjacent or anywhere from 50 to 1000 MHz
- Full PSI/PSIP descriptor injection & restamping with automatic table creation
- Major/Minor and LCN channel numbering — your lineup, your channel numbers
- Rename programs and assign any input stream to any output frequency
Every TV Standard
ATSC, QAM J.83B, DVB-T, DVB-C — One Modulator
Select the television standard per deployment: US antenna ATSC, US cable J.83B QAM 64/256, European and Australian DVB-T/DVB-C, plus DTMB. One unit covers every market.
The RF output is fully digitally synthesized — no harmonics, no spurious emissions — so you can inject the IP-MOD 4X into any coaxial plant next to existing antenna, cable-TV, or VeCOAX modulator channels without interference. It passes through every compression format: MPEG-2 for legacy HD-only TVs, H.264, and HEVC for the newest 4K and 8K sets, with AC3 Dolby / Atmos, AAC, and PCM audio. Real-time FPGA de-jittering, PCR restamping, and automatic packet error correction keep every channel rock solid — even when the incoming streams are not.
Complete Headend
The Perfect Companion for Your Encoders
Encode with VeCASTER, modulate with IP-MOD 4X — and every TV on the coax gets a broadcast-grade HD or 4K channel, while the same streams keep serving your IPTV network.
- Pair with VeCASTER 4K-PRO or VeCODER encoders for complete HD/4K channel headends
- Distribute over coax and stream over IP simultaneously from the same sources
- Mount two units side-by-side in 1RU with the rack plate kit accessory
- Independent management port and streaming input port for clean network design
- Web UI with secure login · silent operation with quiet fan system

FAQ
IP-MOD 4X — Frequently Asked Questions
What does the IP-MOD 4X do?
It converts IP video streams into real television channels on coax. Up to 64 unicast or multicast UDP/RTP streams come in over Ethernet, and up to 4 broadcast-quality RF multiplex channels come out — ready for any TV connected to the coaxial system.
How many streams and channels does it support?
It receives up to 64 IP streams and multiplexes them onto 4 independent RF frequencies, each up to the maximum bitrate allowed by the selected TV standard. You choose exactly which programs go on which frequency.
Which television standards does it support?
ATSC (US antenna digital TV), J.83B QAM 64/256 (US digital cable), DVB-T, DVB-C, and DTMB — selectable in the web interface. One unit covers US, European, Australian, and Asian deployments.
Can I control channel names and numbers on the TVs?
Yes. Each output has a full remultiplexer with PSI/PSIP injection and restamping, program renaming, and Major/Minor plus LCN channel numbering — the lineup on the TVs looks exactly how you design it.
Will it interfere with my existing coax channels?
No. The RF output is fully digitally synthesized with no harmonics or spurious emissions, so it can be combined with existing antenna, cable-TV, or VeCOAX modulator channels — even on adjacent frequencies.
Which encoders does it pair with?
Any UDP/RTP source works. For a complete headend, pair it with our VeCASTER 4K-PRO or VeCODER single- and multi-channel encoders to create HD/4K channels over coax and IP simultaneously.
Do older TVs work with it?
Yes. It passes through MPEG-2 for legacy HD-only televisions as well as H.264 and HEVC for the newest 4K and 8K sets — you choose the codecs that match your audience of TVs.
Can it be rack mounted?
Yes. Two units mount side-by-side in a single 1RU space using the optional rack plate kit — the same plate also holds a VeCASTER encoder next to the modulator.
