Sheet 10 — AV over IP
Solution 10 · AV over IP

The right source. Wherever it is needed.

Share sources across your site with routes that operators can select and a network your IT team can support. Start with the source list, the display list and what must run at the same time.

01Overview

Plan the routes before choosing the network.

AV over IP connects source encoders and display decoders through managed Ethernet switches. A source can serve several displays, while each display selects its own permitted route. We coordinate the source formats, endpoints, network, controls and operating responsibilities as one design.

The three reference configurations below distribute HDMI video with its accompanying audio. They use one compatible endpoint platform and one AV network segment. USB control of remote computers, independent networked audio, recording and browser streaming need their own agreed interfaces and capacity checks.

Reference designs · example quantities · project selection and system tests required. These are starting points for a project, not completed installations or fixed procurement packages.

For remote computer operation, see Control rooms & command centres. For playlists, schedules and content publishing, see Digital signage & retail displays. Those workflows add functions beyond the video routes below.

Reference configurations. Example quantities require project selection, compatibility checks and system acceptance tests. The 10 Gb/s links are calculated choices for these route matrices. They do not guarantee capacity for additional streams, USB, multiple windows or future endpoints. All three configurations use L2 media distribution; routing media between IP subnets is a separate design.

Follow the signal path for your configuration.

Workflow, boundaries and intended result

Composition

Two source encoders, four display decoders, one managed PoE+ access switch, one route controller and one wired operator client. The example includes six HDMI connections, endpoint network cabling and one local rack/power installation set. Two sources, four displays and the agreed IT service connection are client interfaces.

Boundaries

The six endpoints have fixed encoder or decoder roles. There is one selected video feed per display, with its source audio. The base has no inter-switch backbone or automatic network recovery. Remote keyboard/mouse control, multiview and recording are outside this scope.

Intended result

Operators can recall permitted routes and see endpoint status. Commissioning checks all eight source-to-display pairs and simultaneous viewing on all four displays.

Typical architecture · not a project drawing

Workflow, boundaries and intended result

Composition

Six encoders, eight decoders, two managed PoE+ access switches, one duplex optical link with two 10 Gb/s transceivers, one shared controller and two wired operator clients. Fourteen HDMI connections and two local installation sets complete the example.

Boundaries

The calculation allows three different remote sources in each direction at once; displays may share a source. One AV VLAN extends between the switches. The base optical link is single, so its loss removes inter-floor distribution. Local operation during a controller or uplink failure is tested and documented rather than assumed.

Intended result

Eight displays can use an agreed mix of local and remote sources, supported by a tested route matrix and a measured inter-floor load. All 48 source-to-display pairs enter the acceptance schedule.

Typical architecture · not a project drawing

Workflow, boundaries and intended result

Composition

Twelve encoders, eighteen decoders, three managed PoE+ access switches, one shared core, three duplex fibre links with six 10 Gb/s transceivers, one shared controller and three wired operator clients. There are thirty HDMI connections, three access installation sets and one core installation set.

Boundaries

Each display receives one selected primary feed. The example permits up to six distinct incoming remote feeds and four outgoing local feeds per building. The core, controller and each endpoint are single devices. The separately selected R01 option adds a second fibre path to the same core for each building, with controlled link failover; it does not protect against a core or access-switch failure. Core redundancy or routed inter-building media requires a revised design.

Intended result

The site has an explicit routing and ownership plan for all eighteen displays. Acceptance covers all 216 source-to-display pairs, concurrent building traffic and the selected recovery scope.

Common mistakes

And how the design process prevents them.

  1. M01

    Mistake: Counting one transceiver as an encoder and decoder at the same time

    Prevention: Assign one operating role to every endpoint

  2. M02

    Mistake: Assuming all Ethernet AV devices interoperate

    Prevention: Qualify the exact platform, stream type and firmware combination

  3. M03

    Mistake: Selecting the backbone from the display count alone

    Prevention: Calculate distinct subscribed streams in both directions

  4. M04

    Mistake: Using per-port PoE capability as the switch's total power budget

    Prevention: Check the installed PSE supply and all allocated loads

  5. M05

    Mistake: Connecting a spare fibre without a loop-control plan

    Prevention: Configure and test the selected redundant topology

  6. M06

    Mistake: Treating a routed management interface as routed media support

    Prevention: Document AV VLAN boundaries and design multicast routing separately

Single-device failures remain inside the stated recovery boundary.

11Inputs and FAQ

Before we begin.

What to send us, and practical answers before the project starts.

Can we use our existing network?

Possibly. We review switch features, current loading, available ports, power, fibre and IT policies. A VLAN provides separation but does not create bandwidth or prove multicast compatibility.

Does a 10 Gb/s backbone cover every system?

No. In IP-02 and IP-03 it follows the stated source and display arrangement, with one primary feed per display. Extra streams, USB or new endpoints require a new calculation and load test.

Can encoders and decoders from different platforms work together?

Only when their exact media and control interfaces have been qualified together. Ethernet connectivity alone establishes no media compatibility, even when the connectors and advertised resolution match.

Can one endpoint send and receive two independent pictures?

The endpoints selected for these examples operate as an encoder or a decoder. A room that must send one source and receive another independently needs separate endpoints in this design.

Does this include USB, KVM or web streaming?

The base distributes video and accompanying audio to displays. Remote USB control and browser streaming are separate workflows that need qualified interfaces, permissions and additional capacity where applicable.

Can the system cross subnets or link buildings?

Fibre links connect the buildings in IP-03 while keeping media within one L2 AV segment. Routed L3 distribution is possible only after a separate multicast, discovery, control and security design for the selected platform.

What happens when a link or switch fails?

The base has single links and devices. The affected paths may be unavailable until restoration. IP-03's optional R01 spare fibre paths address link failures to the same core; they do not duplicate the core, access switches, endpoints or controller. Agreed interruption limits are tested.

Who runs the system after handover?

A written support boundary assigns switch, endpoint, control, account and firmware duties. Operators receive a route guide; administrators receive configurations, test records and a recovery procedure.
