Sub-Frame Streaming

Ultra-Low Latency

Deliver ultra-low streaming latency with instantaneous sub-frame response directly from the host SBC. A custom hardware-accelerated pipeline eliminates the dropped frames and video stutter of generic IP-KVMs, ensuring fluid 60 FPS rendering for real-time system administration.

Sub-frame encoding guarantees an imperceptible delay between physical input and visual response.45ms LatencyHardware-level network optimization ensures continuous frame delivery even under high bandwidth loads.Zero Dropped FramesHigh-refresh-rate remote rendering for precise cursor control and UI navigation.60 FPS Stream60 FPS

ClientEcosystem

TAILSCALE

Seamlessly integrate into the USBridge Client ecosystem as a unified point of control. Manage hardware KVMs, software agents, and remote desktops over an encrypted, peer-to-peer Tailscale mesh with zero port forwarding.

BIOS-in-TerminalOCR Engine

OFFLINE

Real-time local OCR converts raw video into an interactive terminal stream directly on the device, bypassing cloud dependencies. Copy boot logs, search POST error codes, and administer machines over lightweight SSH.

ImmutableSnapshots

BTRFS ISOLATION

Built on a hardware-isolated Btrfs architecture. Deltas are recorded and instantly frozen as read-only states, providing unbreakable rollbacks against ransomware, corrupted updates, and failed boots.

Virtual StorageISO Media

VIRTUAL DRIVE

Hardware mass storage emulation enables remote mounting of ISO, IMG, VDI, or VMDK images in read-only or read-write modes. Install operating systems and execute bootable rescue utilities out-of-band utilizing high-speed RAM caching.

AutomationMCP Protocol

AI & MCP

Integrate AI models via the Model Context Protocol (MCP) to automate BIOS configuration and execute hardware diagnostics. Utilize Starlark scripts to evaluate verifiable OCR text streams instead of fragile pixel matching.
