Whole-Home Video Distribution
Whole-home video distribution centralizes selected sources while allowing each display zone to choose its program. GGIS selects a fixed HDMI matrix, HDBaseT point-to-point extension, or AV-over-IP from source count, zone count, distance, latency, control, and expansion plans. HDBaseT 3.0 supports 4K60-class video plus Ethernet, USB, and control over category cable on suitable point-to-point links. AV-over-IP generally fits larger or expanding systems better than a fixed matrix.
HDMI 2.1 supports up to 48 Gbps for 4K120 and 8K-class formats, but the requested format works only when every source, switch, cable, extender, receiver, and display in the route supports it. A generic 4K label does not establish 4K120 capability. We document EDID, HDCP, HDR, audio, bandwidth, and mixed-display behavior across the complete chain and keep local sources where centralization creates unnecessary compromise.
What we deliver
- A source-and-zone matrix records resolution, HDR formats, audio capability, control method, simultaneous-use expectations, and content-account constraints
- A fixed HDMI matrix is compared with HDBaseT 3.0 point-to-point links and scalable AV-over-IP according to topology and expansion
- Cat6A home runs and rated local HDMI connections are planned within the transport vendor's distance and bandwidth requirements, with spare pathways where possible
- EDID strategy is designed for mixed displays so one older television does not silently force every zone to the lowest shared video or audio capability
- HDMI 2.1 can carry up to 48 Gbps, but 4K120 or 8K-class operation requires support from every component in the selected route
- Managed switching for IP video includes calculated port speed, uplink capacity, PoE demand, VLAN design, IGMP behavior, and separation from ordinary client traffic
- Control4 or Savant presents consistent room and source names, manages display power and input selection, and exposes only routes the household can use
- A route table, endpoint map, port schedule, and EDID notes are delivered after commissioning
How we approach it
We inventory every source and display by exact model, input, native resolution, frame rate, HDR, audio return, control interface, and simultaneous-use need. Path lengths are measured from rack to endpoint. A stable small system may suit a fixed matrix; a suitable point-to-point run may use HDBaseT 3.0 for 4K60-class video, Ethernet, USB, and control. Larger or expanding systems usually favor AV-over-IP with purpose-designed switching. We identify scaling, audio management, local-source exceptions, account limits, capacity, and spare ports before selecting topology.
Routing is configured with stable source and zone names, explicit EDID behavior, supported scaling, and required audio extraction or downmix. AV-over-IP multicast and VLAN settings follow the selected platform and actual switch architecture. Control4 or Savant coordinates routes with display power, input, AVR state, source control, and realistic delays. Requested 4K120 paths are enabled only after every component is verified for the needed HDMI 2.1 bandwidth; no generic 4K flag is accepted as proof. Exports, addressing, switch settings, and mixed-display compromises are recorded.
Sources, matrix hardware or encoders, network switches, control processors, and power equipment are mounted with adequate rack airflow and access. Cat6A links are terminated consistently, labeled at both ends, and patched to the documented ports; decoders or receivers are secured behind displays without stressing connectors or blocking ventilation. Local HDMI leads are selected for the required bandwidth and kept within suitable lengths.
We build a test matrix that exercises every approved source-to-display route rather than checking one television and assuming the rest. Each combination is reviewed for acquisition time, HDCP handshake, resolution, frame rate, HDR or Dolby Vision indication, color, audio format, lip sync, source control, and recovery after switching away and back. Simultaneous routes are loaded to expose bandwidth or multicast issues. Displays with different capabilities are tested together to verify the EDID plan. Power-cycle recovery, rack temperature, app and keypad commands, local overrides, and the owner's ability to select and stop content complete commissioning.
Frequently asked questions
When is an HDMI matrix preferable to IP video?
A fixed matrix is straightforward for a stable number of sources and zones. HDBaseT 3.0 can serve suitable point-to-point category-cable links with 4K60-class video plus Ethernet, USB, and control. AV-over-IP is generally better for larger, distributed, or expanding systems, though it requires deliberate switching and multicast design. We select from topology and operation rather than brand preference.
Can every television receive 4K HDR at the same time?
Only if every source, switch, cable, extender or decoder, receiver, and display on each route supports the requested format and bandwidth. HDMI 2.1 supports up to 48 Gbps for 4K120 and 8K-class formats, but a generic 4K label does not prove 4K120 support. EDID management can organize compatible modes; it cannot create a capability missing from the chain.
Will centrally located streaming players share profiles cleanly?
Centralization reduces hardware, but account behavior belongs to each streaming service and device. Concurrent-stream limits, household rules, personal recommendations, and authentication still apply. Some rooms are better served by local players when independent profiles, gaming latency, or specialized apps matter.
