HDBaseT vs AV-over-IP: how to get video to every TV in the house without a rat’s nest

The conversation usually starts somewhere in the middle of a kitchen remodel. The homeowner has seven TVs — great room, primary suite, kid bedrooms, basement gym, covered patio — and wants the same Apple TV or cable box to feed any of them, on demand, from a single shelf in the rack. Maybe they’ve seen a friend’s setup where the basketball game follows them from room to room. They want that. They don’t want the rat’s nest of streaming sticks, HDMI dongles, and four different remotes that everyone else seems to live with.

There are two real ways to do this in 2026: HDBaseT (extenders and matrix switches over Cat6/Cat6A) and IP-based video over the home’s data network (AV-over-IP systems like Just Add Power, NETGEAR AVoIP, or Crestron NVX). Both work. They cost different amounts and they win in different houses. This post is the honest comparison — what each actually is, what it costs, and which one we’d recommend on the Wasatch Front and Park City installs we work on.

This is a deeper follow-up to our outdoor TV installation post, which covered getting one TV outside without a rat’s nest. This post covers getting every TV in the house fed from the rack.

What HDBaseT actually is

HDBaseT is a wired, point-to-point video distribution standard that runs uncompressed (or visually lossless) HDMI over a single Cat5e/Cat6/ Cat6A cable for distances up to 100 m. It was designed by the HDBaseT Alliance specifically for long-distance HDMI extension — which is exactly the use case here, because nobody wants a 40 ft HDMI cable run through their walls.

In a real install, HDBaseT shows up in two configurations:

Point-to-point extender pairs. One transmitter at the rack, one receiver at each TV. Each TV is fed by exactly one source. Cheap, simple, no programmability. Fine if you just want to put one Apple TV on a wall mount where the cable run is too long for HDMI.
HDBaseT matrix switch. A 16x16 or 8x8 matrix in the rack. Any of the inputs (Apple TV, cable box, security NVR feed, Ring/Protect tile, gaming PC) can be routed to any of the outputs (any TV in the house). This is the configuration that actually gives you “the basketball game follows you from room to room.”

The HDBaseT 3.0 spec carries 4K/60 HDR with HDCP 2.3, plus bidirectional IR (for controlling the source from the TV remote), Ethernet passthrough (so the TV gets a network connection over the same cable), and PoH (Power over HDBaseT) on some hardware. In practice, that means a single Cat6A run from rack to TV does video, IR control, network, and sometimes power.

What AV-over-IP actually is

AV-over-IP encapsulates HDMI into network packets and distributes it across a regular Ethernet infrastructure. The matrix is no longer a dedicated box; it’s the same managed switch that runs the rest of the house network. Each TV has a small receiver, each source has a small encoder, and the switch fabric handles the routing.

The main systems we work with:

Just Add Power (JAP). The most common AV-over-IP system in residential. 1G and 4K-capable models. Compresses video with low enough latency for live sports and gaming.
Crestron NVX. The high-end option. 10G uncompressed 4K HDR. Programmable deeply by Crestron integrators. Stupid expensive.
SDVoE on enterprise switches. Visually lossless 4K over 10G Ethernet. Used in boardrooms and broadcast more than residential.

The big architectural difference: AV-over-IP scales. An HDBaseT 16x16 matrix is a hardware ceiling. Need a 17th TV? Buy a different matrix. An AV-over-IP deployment just needs one more encoder/decoder pair and a few more switch ports. For homes that grow, that’s a real advantage.

Where HDBaseT wins

Cost, in small-to-medium installs. A 4x4 HDBaseT matrix runs $1,200–2,500. The same capability in JAP is closer to $4,000– 7,000 depending on resolution and feature set. For a 4-TV system that’s never going to grow, HDBaseT is dramatically cheaper.
Latency. Uncompressed HDBaseT has effectively zero latency — it’s just HDMI on a longer wire. Compressed AV-over- IP has 1–2 frames of latency, which matters for real-time gaming (especially competitive shooters) but not for sports or movies.
Predictable behavior. An HDBaseT matrix is a dedicated appliance with one job. It doesn’t fight with your VLAN config, doesn’t depend on multicast behavior, and doesn’t care what your UniFi controller did with channel widths last night. The audio delay between TVs in the same room is also rock-solid, which matters if you’re running multi-room TVs in the same open-concept great room.
EDID handling. A real HDBaseT matrix gives you per-output EDID management, so a 4K TV in the great room gets full 4K HDR while the 1080p TV in the workout room gets a 1080p EDID. Source devices like Apple TV auto-negotiate to whatever the matrix tells them. Most AV-over-IP systems do this too, but HDBaseT was built around it from day one.
Network independence. HDBaseT runs on its own dedicated cabling. If your network goes sideways, your video distribution keeps working. With AV-over-IP, the video and the network are the same thing — an IGMP querier misconfiguration takes down both.

Where AV-over-IP wins

Scale. Want 12 TVs and 8 sources today, with the option to add four more next year? AV-over-IP. No matrix-replacement cost when you outgrow the original spec.
Mixed-source flexibility. Want to drop a security camera tile, the Ring doorbell live feed, or a UniFi Protect view onto a TV alongside the Apple TV? AV-over-IP handles arbitrary IP-streaming sources cleanly. HDBaseT can do it via an external encoder, but it’s clunkier.
Single cabling plant. One Cat6A pull per TV serves both the network and the video. No separate “HDBaseT homerun.” On a new build, that’s a real cost saving in cable, labor, and conduit.
Unconventional layouts. A detached pool house, a guest casita, or a Park City barndominium that’s 200 ft from the main rack. HDBaseT is capped at 100 m point-to-point. AV-over-IP just needs network connectivity, which can be a fiber link or even a properly engineered wireless backhaul.
Programmability. If the home is already on a Crestron, Control4, or Savant control system, AV-over-IP integrates more natively. Switching a TV input becomes a scene button press, not a separate IR command.

Where each one breaks

Both systems have failure modes that matter on installs we’ve done.

HDBaseT failure modes

Cable runs too long or too marginal. HDBaseT’s 100 m spec assumes Cat6A properly terminated, no kinks, no sharp bends. On a 90 m run with a single bad pair, you get “HDCP handshake failed” and intermittent black screens. Same loose-pair problem we covered in the AP-rebooting post, just at higher signaling rates.
Power supplies and PoH. A matrix that loses its receiver-side power supply just stops working at one TV. PoH simplifies this if your matrix supports it, but not every model does.
Hardware ceiling. The day you add the 17th TV to a 16x16 matrix is the day you find out whether your installer planned for a daisy-chained second matrix or quietly sized the original way too small.

AV-over-IP failure modes

Multicast misconfiguration. AV-over-IP is multicast-heavy. A switch without proper IGMP snooping, an IGMP querier in the wrong place, or PIM enabled where it shouldn’t be will cause video stutter, black frames, or 100% CPU on the switch. We’ve walked into Holladay installs where the homeowner’s consumer router was flooding multicast everywhere and nothing worked. This is the same class of problem we talked about with Sonos drops on poorly configured networks — just higher-stakes.
VLAN architecture. AV-over-IP typically wants its own VLAN with multicast flooding allowed and IGMP snooping enabled, but it has to inter-route with the controller VLAN where the touchscreens and apps live. Done wrong, half the system can’t see the other half. Our VLANs explained post covers the basic theory; AV-over-IP needs a careful application of it.
Switch sizing. A 1G AV-over-IP system fills a switch port with about 850 Mbps per stream. A house with 8 simultaneous streams running through a single 1G uplink to the rest of the network is going to crush that uplink. Multi-gig or 10G aggregation matters.
Mixed switch hardware. Just Add Power and similar systems prefer specific switch makes and models because they need multicast behavior to be predictable. We’ve seen JAP fall over on consumer Netgear smart-managed switches that worked fine on the LAN side. The managed vs unmanaged switch post covers why this matters.

Cost comparison, real numbers

Rough numbers for a 6-TV / 4-source residential install we’d quote in 2026, hardware only (cabling, programming, and labor extra):

HDBaseT 4K matrix, 8x8. $4,000–6,500 for the matrix, $250– 400 per receiver. Total in the $6,000– 9,000 range.
Just Add Power 3G+ (1080p) or similar. $200–350 per encoder, $200–350 per decoder, plus the dedicated switch. Total in the $5,000–7,500 range.
Just Add Power 4K. Roughly $500–750 per encoder, $500–750 per decoder, plus a multi-gig switch. Total in the $9,000–14,000 range.
Crestron NVX 10G. $2,000– 3,500 per endpoint, plus a 10G enterprise switch and Crestron control programming. The same 6-TV / 4-source install starts around $30,000 and goes up. This is luxury-tier only.

For 80% of Wasatch Front custom homes in the $1M– 3M range, HDBaseT or 1080p AV-over-IP both deliver what the homeowner actually wants. NVX comes into its own at $5M+ and on the kind of properties where a Crestron control system was already a foregone conclusion.

Cabling assumptions are different

Before any of this works, the cabling has to be right. Both technologies assume Cat6A end to end on video runs — Cat6 will mostly work for HDBaseT up to 4K but degrades to glitches at long lengths, and AV-over-IP at 4K wants the headroom Cat6A provides. Our Cat5e vs Cat6 vs Cat6A post covers the rationale.

For a new build, the plan is straightforward: one Cat6A homerun per TV location to the rack, one or two more per source location, and conduit between them if the budget allows for future flexibility. We added video distribution to our standard pre-wire checklist explicitly because retrofitting either system later is dramatically more expensive than pulling cable during framing.

For a retrofit, the calculus changes. If the existing pulls are Cat5e and the homeowner doesn’t want to open walls, HDBaseT extenders certified for Cat5e at 1080p still work, and that’s a practical option for older homes in the Avenues or Sugarhouse where re-cabling is genuinely impractical.

What we recommend by household

4-TV new build, no plans to expand. HDBaseT 4x4 matrix. Roughly $4,000 in hardware, 100% reliability, simple to support.
6–8 TV new build, growing family. Just Add Power 4K on a properly engineered network. Future TVs are incremental cost, not matrix-replacement cost.
Park City or Heber estate with detached structures. AV-over-IP, with fiber runs to the casita, pool house, or barn. HDBaseT can’t reach.
$5M+ luxury home with full Crestron install. Crestron NVX. The integrator is already programming the system and the incremental complexity disappears.
Retrofit on Cat5e cabling, no walls opening. HDBaseT 1080p extenders. Set expectations on resolution and live with it.
One Apple TV, one outdoor TV, no other distribution. Don’t buy a matrix of any kind. A single HDBaseT extender pair is fine. See our outdoor TV post for the simple version.

Audio is its own thing

One trap worth flagging: video distribution is not audio distribution. HDBaseT and AV-over-IP both carry audio along with the HDMI signal, but they don’t do whole-home audio in the way Sonos, Casa Tunes, or a real distributed-audio amp does. Trying to use a video matrix as a music distributor ends in pain — sources don’t sync, switching between rooms is clunky, and you’ve burned a video output to play Spotify in the kitchen. Our whole-home audio post covers the audio side properly. Plan video and audio as separate systems that share a rack but do different jobs.

Bottom line

HDBaseT is the right answer for most fixed-size, small-to-medium video distribution jobs in 2026. It’s simpler, cheaper, network-independent, and behaves predictably on a Wasatch Front custom home with a properly cabled rack. AV-over-IP is the right answer when the system needs to scale, when the geography requires it (detached structures, unusual distances), or when the homeowner is already committed to a programmable control system that benefits from native IP integration.

The mistake we see most often is people picking AV-over-IP for the wrong reason — because it sounds more modern — on a 4-TV install where a $4K matrix would have done the same job for half the money and a tenth of the multicast headaches. Match the technology to the actual layout and the actual TV count, not to the marketing.
