1. Architecture & Components

• Device roles
  • Encoder: captures audio/video, compresses, packets for IP networks.
  • Decoder: receives streams, decodes, outputs to displays/speakers.
  • Transcoder (optional): converts codec/bitrate for compatibility.
• Key hardware blocks
  • SoC (ARM-class CPU + hardware video codec accelerator)
  • DRAM and flash (firmware, buffers)
  • Network interfaces: 1–10 GbE, SFP option
  • I/O: HDMI/SDI in/out, analog audio I/O, GPIO, RS-232/RS-485, IR
  • Optional Wi‑Fi / Bluetooth management port
• Firmware stack
  • Bootloader (secure boot recommended)
  • Linux-based kernel (real-time extensions optional)
  • Media pipeline: capture → encode → packetize
  • Management services: REST/gRPC/Proprietary API, web UI, SNMP, NTP, logging
  • Security modules: TLS stack, authentication, firmware signing

12. Compliance & Standards

• Follow RTP/RTSP, SMPTE (for SDI/HD-SDI interfaces), IEEE 802.1Q for VLANs, and AES67 where audio-over-IP interoperability is required.
• For regulated environments, ensure encryption-at-rest for local recordings and follow organizational logging/retention policies.

Pros

• No Monthly Subscription: Unlike LiveU or Teradek, Ucast doesn't take a cut. You own the hardware outright.
• Sub-Second Latency: In SRT mode, it rivals bonded cellular solutions costing three times as much.
• Hot-Swappable Battery: The Sony NPF-style battery bay means you can run all day with a pocket full of cheap batteries.
• eSIM Support: Perfect for international travel; you can buy a local data plan without visiting a store.
• H.265 Encoding: Saves bandwidth and data costs while maintaining high fidelity.
