Executive Summary
AV distribution is shifting from dedicated hardware matrix switchers to software-defined AV over IP. This white paper gives systems integrators a framework for evaluating which architecture is right for each application.
1. Traditional Matrix Switching
A matrix switcher has fixed inputs and outputs in a crosspoint fabric. Any input routes to any output. Routing is hardware-switched and instantaneous.
Strengths: Zero latency. No network dependency. Simple infrastructure (HDMI cables only). Single-vendor accountability. Proven reliability.
Limitations: Fixed I/O — upgrading means replacing the chassis. HDMI limited to 5m passive, requiring HDBaseT extenders for longer runs. Every display needs a dedicated cable run. Hardware failure is a single point of failure.
2. AV over IP
Sources connect to encoders that packetize video as IP streams. Displays connect to decoders. The managed Ethernet switch is the routing fabric.
| Codec | Quality | Latency | Bandwidth | Network |
|---|---|---|---|---|
| JPEG2000 | Visually lossless | ~1 frame | ~500 Mbps | 1G managed |
| H.265 | Lossy | 50-200ms | 30-80 Mbps | 1G managed |
| SDVoE | Uncompressed | ~0ms | ~9.5 Gbps | 10G managed |
Strengths: Unlimited scalability (add one decoder per display). Distance via CAT6a to 100m or fiber to kilometers. Multicast delivers one stream to unlimited decoders at no extra bandwidth. Single device failure does not affect other paths. Software-defined routing with no rewiring.
Limitations: Requires correctly configured managed switch — IGMP snooping, MTU 9000 (JPEG2000/SDVoE), flow control disabled, VLAN isolation recommended. Misconfiguration causes total failure. Latency (except SDVoE). Compression (except SDVoE). Higher per-port cost below 8-16 outputs.
3. Decision Framework
| Scenario | Recommended |
|---|---|
| Broadcast / live production | SDVoE or traditional matrix (zero latency required) |
| Corporate AV, 4-16 displays, single floor | Traditional matrix (lower cost, no IT dependency) |
| Large campus, 20+ displays across floors | AV over IP / JPEG2000 (leverages existing network) |
| Digital signage, 10-100 displays | AV over IP / H.265 (multicast efficiency at scale) |
| Video wall, 9+ panels | AV over IP / JPEG2000 (9x9 wall built in) |
| Healthcare / medical imaging | SDVoE or traditional matrix (lossless required) |
| Sports bar / hospitality, 20-60 displays | Flex Matrix or AV over IP |
| Education, 1:many distribution | AV over IP / H.265 (campus-wide multicast) |
4. Network Requirements
The most common AV over IP failure mode is network misconfiguration. Before specifying AV over IP, integrators must either develop network competency or establish a reliable IT partnership. Critical requirements: IGMP snooping enabled per VLAN, IGMP querier on the AV VLAN, MTU 9000 for JPEG2000/SDVoE, flow control disabled, dedicated AV VLAN recommended. Size uplinks at 10G for JPEG2000 deployments with multiple streams per segment.
5. Total Cost of Ownership
Small (8x8): Traditional matrix is typically 30-50% less expensive. AV over IP complexity premium not justified for a boardroom.
Medium (16x24): Economics equalize. AV over IP gains where managed Ethernet already exists. CAT6a home runs often cost less than HDBaseT runs.
Large (24+ in, 36+ out): AV over IP generally wins. The 37th output costs one decoder + one switch port vs. a new or larger chassis for the traditional matrix. The scalability advantage compounds at scale.
6. KanexPro Products
AV over IP: JPEG2000 series (AVO-IPJP2K, AVO-IPJP2KS, AVO-IPJP2KD) | H.265 series (AVO-IP265-4K, AVO-IP265-HD) | SDVoE (AVO-IPSDV-4K) | IP Controllers (AVO-IPCTL-JP2K, AVO-IPCTL-265, AVO-IPCTL-SDV)
Modular Matrix: FLEX series (FLEX-MF8X10, FLEX-MF16X20, FLEX-MF24X36, FLEX-MF24X60) with HDMI and CATx card options
7. Conclusion
AV over IP vs. matrix has no universal answer. Scale, latency, signal quality requirements, existing infrastructure, IT environment, and budget all drive the decision. Integrators who can competently specify both architectures and articulate the tradeoffs clearly will close more business and deliver better outcomes than those committed to a single approach.
Above 16 outputs or in deployments with existing Ethernet infrastructure, AV over IP typically offers superior TCO and flexibility. For broadcast, medical, small-scale corporate, and latency-sensitive applications, traditional matrix switching or SDVoE remains the right choice.
