A dozen-plus televisions showing a dozen different games, with staff able to group any set of screens into one marquee view and choose which single game's commentary plays over the room speakers, is a Crestron DM NVX AV-over-IP design problem, not a cabling problem. Video goes over the network to every screen independently through DM NVX encoders and decoders, screens are grouped into a shared view using video wall processing or Multiview compositing, and the audio for one selected game is broken away from its video and routed separately to the room's sound system using DM NVX breakaway audio or DM NAX audio-over-IP. One touch panel can drive all three functions because they are controlled from the same Crestron platform.
How does independent per-screen routing actually work?
Each source — a cable box, streaming device, or satellite receiver — connects to a DM NVX encoder, and each television is fed by a DM NVX decoder. Because the signal moves over standard Gigabit Ethernet rather than dedicated matrix cabling, any encoder's stream can reach any decoder, and the system scales by adding endpoints rather than rewiring a matrix. As Crestron puts it, "we can bring any source to any screen, we can put content onto different resolution screens, we can scale it up quickly" (DM NVX AV-over-IP: The Full Picture). For a sports lounge that means a dozen-plus screens can each show a different game pulled from its own source, with no screen locked to a shared feed.
For the operator, this is the same architecture Cave Group designs into a hospitality AV system more broadly — the network carries video, audio, USB, and control on one platform rather than a stack of single-purpose boxes.
How do you group screens for a single featured game?
Two different DM NVX features cover this, and the right one depends on whether "grouping" means a true video wall of separate physical displays or a single display split into panes showing several games at once.
For a true video wall — multiple physical TVs tiled to act as one large image — DM NVX video wall processing supports configurations of up to 64 individual displays, with each endpoint providing "fully adjustable zoom capability and bezel compensation to accommodate a range of video wall configurations and display types," at one DM NVX endpoint per display (DM-NVX-363 manual). That is the mode to use when several of the lounge's televisions are mounted together and should present one enlarged picture of the featured match.
For putting multiple games on a single screen at once — useful on a hero display near the bar — the DM NVX 384 encoder/decoder's Multiview feature composes up to six sources into fixed layouts, with 18 available compositions, each pane individually labeled with a text overlay for identification. Crestron names this use case directly: "The most obvious is likely a sports bar — having multiple games on a large-format display with all that content being delivered as simply and efficiently as DM NVX AV-over-IP can make it is a huge benefit" (DM NVX AV-over-IP Technology — Now with Multiview). Multiview also supports borders, color-coding, and fades or wipes between sources, which gives staff a fast way to swap which game sits in which pane without re-routing the whole system.
How do you make one game's audio play over the room speakers?
This is where breakaway audio does the work video routing can't. A DM NVX decoder "can select and combine separate video and audio signals from two different inputs or even two different encoders," meaning a screen can keep displaying one game's video while the room's sound system plays a completely different source's audio — or, for a sports lounge, the selected game's commentary can be pulled off its video and sent to the distributed speakers while every screen stays on mute or captioned (DM-NVX-363 manual). Combining audio and video from two separate encoders is limited to two-channel stereo, which is normally sufficient for a game's commentary feed over bar and lounge speakers.
DM NAX, Crestron's audio-over-IP ecosystem built on the AES67 standard, is the natural carrier for that breakaway signal once it's off the video network. As Crestron's product team frames it, "audio from nearly any source can be encoded to a DM NAX, Dante, or other AoIP protocol and freely routed between devices on the network. Network audio devices handle signal routing and processing and can be remotely configured, managed, monitored, and controlled" (DM NAX Audio-over-IP for Commercial Applications). In practice, that means a bartender or manager picks the featured game's audio on a touch panel, and DM NAX zone amplifiers push it to whichever speaker zones the room is using — bar area, lounge seating, patio — independent of which games are showing where.
What should be planned before the screens and speakers are specified?
A few decisions belong at the design stage rather than after televisions are mounted:
- Source count and type. Each independent game needs its own encoder and its own tuner, cable box, or streaming source — the system doesn't create extra channels out of one feed.
- Network backbone. DM NVX runs on standard Gigabit Ethernet, but ask your network designer whether a nonblocking, properly segmented network with dedicated VLANs for AV traffic is warranted for a venue running a dozen-plus simultaneous video streams.
- Which screens are candidates for video-wall grouping. Physical tiling only works cleanly where adjacent TVs were mounted with that in mind; retrofitting a wall grouping after the fact is harder, and this is worth raising with your integrator before TV mounts go up.
- How many simultaneous breakaway audio zones the room needs. A sports lounge with a separate patio or private area may want more than one independently selectable audio feed, not just one for the whole room — a question to put to your AV contractor during design.
- Staff control simplicity. A touch panel interface that lets staff select "Game 5 to screens 3, 4, 9" and "audio from Game 2 to bar speakers" in a couple of taps is a programming decision worth specifying up front, not an afterthought.
These are reasonable questions to put directly to a Crestron integrator or your venue's AV contractor before committing to a layout.
Frequently asked questions
Can every TV in the lounge show a different game at once?
Yes. With a DM NVX encoder on each source and a decoder feeding each display, any source can route to any screen independently, since the system distributes video over the network rather than through a fixed matrix.
Can we combine several TVs into one big picture for the championship game?
Yes, using DM NVX video wall processing, which supports configurations of up to 64 displays with per-endpoint zoom and bezel compensation — one DM NVX endpoint is required per physical display in the wall.
How does the bar play only one game's commentary when a dozen games are on screen?
DM NVX breakaway audio lets a decoder combine video from one encoder with audio from a different encoder, so the room speakers can carry one selected game's sound while every screen keeps showing its own picture, typically muted or captioned. Combining audio and video across two separate encoders is limited to two-channel stereo.
Can one screen show several games at the same time instead of a full video wall?
Yes, the DM NVX 384 encoder/decoder's Multiview feature composes up to six sources into a single display using fixed layouts, with text overlays to label each pane, which suits a hero screen behind the bar.
Does this require a dedicated AV network separate from hotel guest Wi-Fi?
DM NVX can run on a standard Gigabit Ethernet network, and network port selection can separate AV traffic onto its own VLANs; the exact segmentation plan should be worked out with your network designer based on the property's existing infrastructure.
