FAQ: AV over IP

FAQ: AV over IP

General

What is the difference between JPEG2000, H.265, and SDVoE?

JPEG2000 delivers visually lossless 4K60 over 1G with ~1 frame latency — best for video walls and enterprise. H.265 delivers 4K60/HD over 1G with low latency and up to 50% less bandwidth than H.264 — best for large deployments and digital signage. SDVoE delivers uncompressed 4K60 over 10G with zero latency — best for broadcast and control rooms.

Can I mix JPEG2000 and H.265 encoders/decoders on the same network?

No. Encoders and decoders must use the same codec family. JPEG2000 encoders only work with JPEG2000 decoders, and each controller is codec-specific.

How many encoders and decoders can I have on one system?

JPEG2000 and H.265 support up to 9×9 matrix configurations (9 encoders, 9 decoders) using the IP controller. SDVoE scales with available 10G switch ports.

Do I need an IP controller?

No — it is optional. Without one, encoders and decoders auto-discover and route via the web GUI on each device. The controller adds centralized matrix routing, video wall, REST API, RS-232, and third-party control.

Network

Will an unmanaged switch work?

No. AV over IP requires a managed switch with IGMP snooping enabled. Unmanaged switches cause multicast flooding and prevent video delivery.

Why is there no signal after connecting everything?

The most common cause is IGMP snooping not enabled on the switch. See Troubleshooting: No Signal Between Encoder and Decoder for the full checklist.

Do I need jumbo frames enabled?

For JPEG2000 and SDVoE: yes — MTU 9000 on all AV switch ports. For H.265: no — standard 1500-byte MTU is fine.

Can AV over IP share the same network as corporate data?

Yes, but a dedicated VLAN is strongly recommended to isolate multicast traffic.

Video Wall

Which codecs support video wall mode?

JPEG2000 only. H.265 and SDVoE do not support video wall mode.

What is the maximum video wall size?

9×9 (81 displays) using the AVO-IPCTL-JP2K with JPEG2000 encoders and decoders.

What is bezel compensation?

Bezel compensation crops the image behind each display's physical bezel so the image appears seamless across all panels. Configured in millimeters in the controller GUI.

Audio

Which models support Dante audio?

AVO-IPJP2K (optional Dante AV-A) and AVO-IPJP2KD (dedicated Dante LAN port).

Which models support ARC/eARC?

AVO-IPJP2K and AVO-IPJP2KD. The Slim model (AVO-IPJP2KS) does not.

Installation

What cable type is required?

CAT5e minimum; CAT6 or CAT6a recommended for runs over 50m or SDVoE 10G. Max copper run: 100m. Fiber SFP available on select JPEG2000 models.

Can encoders and decoders be on different subnets?

No. All encoders, decoders, and the IP controller must be on the same IP subnet.
