Massive connectivity merges seamlessly with advanced 12G-SDI routing in the Blackmagic Design Videohub 40x40 12G. This compact 1 RU solution...
Eight camera inputs that each take either HDMI or 3G-SDI, four auxiliary channels for network and USB sources, and nine independent recorders share one chassis in the Osee GoStream Omni 12 ISO. Processing in this 12-channel live streaming video mixer runs on dedicated FPGA hardware rather than a desktop operating system, so keyers, MultiSource layouts, replay and three outgoing streams can all be active at once – nobody has to watch a CPU graph during the show.
Every main input carries both an HDMI Type A port and a BNC connector, and the switcher detects which of the two is live. HDMI accepts sources up to 2160p60, SDI handles 3G signals up to 1080p60 (Level A and B), and each input passes through a frame synchroniser before entering the 4:2:2 YCbCr pipeline. A crew can therefore mix mirrorless bodies, broadcast camcorders and a presenter's laptop without a single external converter. Auxiliary channels 1–2 act as media players or as NDI HX, SRT and RTMP receivers; channels 3–4 take USB-C webcams or the same network feeds. That is how a remote guest on SRT or a breakout room on NDI joins the programme.
The "ISO" in the name refers to the recording engine. The programme output plus up to eight selectable inputs are written simultaneously as MP4 files (H.264, with H.265 also available) at up to 70 Mbps, either to a CFexpress Type B card or to a drive on the USB-C port. Current firmware also stores a separate WAV file next to each recorded channel. For the editor, this multicam ISO recording puts every angle on the timeline the moment the event ends; a missed cut in the live programme becomes a quick correction rather than a problem to explain to the client. Recording has its own bank of encoders, separate from streaming, so a deliberately low upload bitrate never touches the quality of the masters. Inputs you don't need can be excluded to save card space.

Distribution is handled internally too. A hardware encoder sends as many as three RTMP live streams at once, at 1080p and up to 20 Mbps over Ethernet – YouTube, a corporate CDN and the client's own platform in parallel, with no streaming PC. Over USB-C the programme appears as a UVC webcam at 1080p60 in vMix, OBS or Zoom. Two HDMI outputs and two SDI buses (four BNC connectors, each bus doubled) can carry any input, PGM, PVW, clean feed, MultiSource or Multiview. The Multiview itself shows PGM/PVW plus 7 or 15 assignable windows, with audio meters and red/green tally borders. Assignments change mid-show without disturbing the recorded or streamed programme, so one unit feeds an LED wall, a stage confidence monitor and an external recorder.
Sports and event producers get tools that normally need a second device. A DDR buffer continuously records a chosen input, and one key in the PLAYER section replays the last moments at 0.5×, 0.33× or 0.25× through Player 2. Player 1 meanwhile holds a stinger transition with alpha, so a branded replay wipe into slow motion runs from the same panel. For interviews and video podcasts, a 4K signal on HDMI input 1 can be cropped into three independent 1080p shots – 4K ROI virtual cameras – giving a wide and two close-ups from a single locked-off camera.
Four upstream keyers (luma, chroma, pattern, PiP), two downstream keyers, two alpha-capable still generators and a five-layer MultiSource compositor handle green screen, lower thirds, logos, scoreboards and talk-show split layouts. Transitions include cut, mix, wipe, dip and stinger. Graphics rendered in vMix, ProPresenter, UNO or H2R arrive with transparency over one HDMI cable through GoStream Overlay, which saves both a fill/key interface and an input.
Audio gets the same attention. Two XLR inputs switch between mic and line level and supply 48 V phantom power for condenser microphones; the 3.5 mm TRS input can be split into two mono mic channels, giving four independent mics alongside embedded camera audio in a 16-channel mixer. Each mic channel gets a compressor, three-band EQ, a gate and AI-based suppression of air-conditioning and room noise, plus adjustable delay to line analogue sound up with picture; a limiter guards the programme bus. With audio-follow-video or AI voice-detected auto switching, a single operator can run a panel discussion in which the shot follows whoever is speaking.
Control stays hands-on. The broadcast-style surface has PGM and PVW rows, a T-bar, dedicated key buttons and a joystick for PTZ camera control via VISCA over IP – seven cameras with ten stored positions each. Ten macros and ten scenes sit on the panel, up to 100 macros live in the free PC software (network or USB-C), and Bitfocus Companion with Stream Deck lets a second operator take over graphics or replays. A built-in hotspot opens the configuration page on a phone via QR code, and show profiles exported to the CFexpress card can be loaded onto another unit. The switcher runs from a 12 V / 72 W supply and is rated for 0–40 °C.
On a paid job, every extra box means another power supply, another cable run and another thing that can fail. Bringing switching, ISO recording, streaming, replay, PTZ control and audio into the Osee GoStream Omni 12 ISO shortens load-ins and keeps troubleshooting simple. Osee continues to develop the platform through regular firmware releases and publishes a network protocol for tally systems. If you are building a complete package, we can help match CFexpress media, SDI cabling and compatible PTZ cameras.
