Three Ways to Drive a Video Wall
Every professional video wall deployment starts with an architecture decision. Most of the industry presents this as a binary choice between centralized hardware processing and AV-over-IP. In reality, there are three distinct approaches, and understanding the differences between them determines whether your investment delivers for the next decade or becomes a compromise you regret within a year.
This guide breaks down all three video wall processing architectures: centralized hardware, compressed AV-over-IP, and uncompressed distributed processing, a category that Jupiter pioneered and remains the only manufacturer to offer.
Centralized Hardware Processing
In a hardware-based architecture, a dedicated chassis sits in your equipment rack and handles all video processing in one place. Sources connect to input cards via HDMI, DisplayPort, SDI, or IP interfaces. The processor decodes every source, composites them into the desired layout, and sends the result to output cards that drive your display panels directly.
The Catalyst is Jupiter’s flagship hardware processor. A Catalyst system can scale to handle well over a hundred simultaneous sources, processing billions of pixels per second with sub-frame latency and driving video walls at up to 4K60 output. Everything happens inside the chassis over a high-bandwidth internal backplane that is not subject to network congestion, packet loss, or jitter.
On the Catalyst platform, Canvas delivers its full operator experience: drag-and-drop layout editing, source annotation, preset recall, role-based access control, and browser-based remote management from any authorized workstation. Operators can rearrange the wall in seconds without leaving their desk.
Hardware processing dominates in environments where latency tolerance is measured in frames: military command centers, air traffic control, emergency operations, and security operations centers with high source density. The signal path is deterministic, and every pixel arrives exactly when and where it should.
Compressed AV-over-IP: The Industry Standard
AV-over-IP is the most commonly discussed alternative to hardware processing. Instead of routing sources to a central chassis, each source and each display gets a network endpoint. Source-side encoders compress the video into IP packets and transmit them over standard Ethernet infrastructure. Display-side decoders decompress and render the video on the panel.
The key word is compress. Every AV-over-IP system on the market compresses the video stream before transmitting it. The compression algorithms vary, some are visually lossless at typical viewing distances, but the pixel data is always altered. What arrives at the decoder is a mathematical approximation of the original source, not an exact copy.
For many commercial applications, this compression is acceptable. Digital signage, corporate lobbies, and general-purpose meeting rooms rarely require pixel-perfect fidelity. The trade-off buys you distance: AV-over-IP systems work over standard network switches, so sources and displays can be in different rooms, floors, or buildings without dedicated video cabling.
The limitations appear in mission-critical environments. Compression adds latency (the encode-transmit-decode pipeline), introduces artifacts under certain content conditions (rapidly changing data, fine text at small sizes), and fundamentally alters the source data. For environments where operators must read small text, interpret precise color values in monitoring dashboards, or where the data itself is classified and pixel-level integrity is a security requirement, compression is not an acceptable trade-off.
Uncompressed Distributed Processing: The Architecture Only Jupiter Offers
There is a third approach that does not fit neatly into the hardware-versus-AV-over-IP framework, because it combines the reach of distributed systems with the pixel-perfect fidelity of hardware processing. PixelNet delivers true distributed video wall processing over a secure, enclosed L2 network with zero compression.
Unlike every AV-over-IP system on the market, PixelNet does not compress the video stream. Not “visually lossless.” Not “perceptually transparent.” Zero compression. Every pixel that leaves the source arrives at the display exactly as it was captured. This is not an engineering nicety. For organizations displaying classified intelligence data, real-time security feeds, or sensitive operational information, any alteration of pixel data is a security concern. Compression algorithms make decisions about which data to discard. In environments where the wrong pixel value could mean a misread coordinate, a misidentified target, or a missed anomaly in a surveillance feed, that is not acceptable.
PixelNet operates over a dedicated, enclosed Layer 2 network that is physically isolated from the corporate LAN. This is not a VLAN on shared infrastructure. It is a separate network with its own switches, its own cabling, and no path to the outside world. The system was designed from the ground up for environments where network security is not a configuration setting but a physical architecture requirement.
Jupiter is the only company in the world that offers true distributed video wall processing at this level. No other manufacturer can deliver uncompressed pixel data across an entire building or multi-room campus while maintaining the security isolation that classified environments demand.
Operator Control Across Architectures
The processing architecture determines how video gets from source to display. But operators care about something different: can they control what appears on the wall, and can they do it quickly?
On the Catalyst hardware platform, Canvas provides the full operator experience. Operators get browser-based control from any authorized workstation, with drag-and-drop layout editing, source annotation, preset management, and role-based access. A desktop client enables direct interaction with sources on the wall, including annotation and editing overlays.
On PixelNet, the operator experience works differently. Instead of a desktop client, PixelNet uses standalone display nodes that show selective sources from the network. Operators interact with sources through KVM (keyboard, video, mouse) control, either through VNC for IP-encoded sources or through the KM Link for HDMI-connected sources. This approach gives operators direct control of the actual source machines rather than just a view of their output, which is often exactly what security operations and command environments require.
Compressed AV-over-IP systems vary widely in operator control capabilities depending on the manufacturer. Some offer basic switching and layout recall. Others provide more advanced management interfaces. Evaluate the operator software as critically as you evaluate the processing hardware, because the interface determines whether your team uses the system effectively or fights it daily.
When Each Architecture Fits
Choose centralized hardware (Catalyst) when your deployment is concentrated in a single room or adjacent rooms, when you need sub-frame latency, when source density is high, and when operators need the full Canvas experience with desktop annotation and editing capabilities. Typical environments: primary NOCs, SOCs, emergency management, military command centers.
Choose compressed AV-over-IP when pixel-perfect fidelity is not critical, when you need to distribute content across standard corporate network infrastructure, and when the use case is commercial rather than mission-critical. Typical environments: corporate lobbies, digital signage networks, campus-wide content distribution for non-sensitive data.
Choose uncompressed distributed (PixelNet) when you need campus-wide or multi-building reach but cannot accept compression, when the data being displayed is classified or security-sensitive, when the network must be physically isolated, and when operators need direct KVM control of source machines. Typical environments: intelligence fusion centers, defense command facilities, government operations spanning multiple rooms or buildings, critical infrastructure monitoring.
Combining Architectures
Some facilities benefit from deploying more than one architecture. A primary command center might use Catalyst for its main wall where source density and Canvas full-feature control matter most, while using PixelNet to connect satellite rooms in adjacent buildings where uncompressed, secure distribution is required. Jupiter is the only manufacturer that can provide both architectures under a single support and integration relationship.
