PRODUCT OVERVIEW & HARDWARE DATASHEET

EXECUTIVE SUMMARY

Designed for mission-critical broadcast production environments, the Broadcast Studio Uncompressed 4K Video Network Switch delivers deterministic, sub-microsecond latency switching for 12G-SDI, SMPTE ST 2110, and NDI-capable video streams. Unlike conventional Ethernet switches, this platform guarantees zero frame loss, constant bitrate forwarding, and full hitless redundancy essential for live production, post-production, and master control room operations. The switch operates as a fully non-blocking Layer 2/Layer 3 device with integrated PTP (Precision Time Protocol) grandmaster capabilities, ensuring genlock-accurate switching across 4Kp60 4:4:4 uncompressed flows.

HARDWARE ARCHITECTURE & SILICON

The forwarding plane is built upon a purpose-designed Video-Aware ASIC that processes SMPTE ST 2022-7 seamless protection switching in hardware. Each of the 48 front-panel SFP28 cages supports 25Gbps line rate, configurable as 12G-SDI, 25G Ethernet, or dual 10G breakout modes. The backplane provides 2.4 Tbps of non-blocking switching capacity, with a cut-through latency of 480 nanoseconds for 4K video frames. A dedicated FPGA cluster manages video timing reconstruction, PTP profile handling (SMPTE ST 2059-2), and ANC (Ancillary Data) preservation across switch fabrics.

KEY FEATURES & ROUTING LOGIC

- Uncompressed 4K Video Switching: Hardware-based forwarding for 12G-SDI over IP (SMPTE ST 2110-20/21), supporting 4Kp60 RGB 4:4:4 with full ancillary data preservation.

- Hitless Protection Switching: Implements ST 2022-7 seamless redundancy with under 1 microsecond failover, utilizing duplicate flows across separate fiber paths.

- PTP Grandmaster & Boundary Clock: Integrated GNSS receiver input with holdover stability of ±5ppb, enabling studio-wide genlock without external timing gear.

- Zero Packet Loss Flow Control: Priority flow control (PFC) with per-priority pause thresholds engineered for constant bitrate video streams, eliminating RTP jitter.

- NMOS IS-04/IS-05 Discovery: Native support for AMWA NMOS Node API, allowing automatic registration with broadcast controllers (e.g., Sony LSM, Grass Valley GV Orbit).

COMPLIANCE & STANDARDS

The platform is certified for SMPTE ST 2110-10/-20/-21/-30/-40, SMPTE ST 2059-2 (PTP), AES67 (audio over IP), and AMWA NMOS. It carries AIMS (Alliance for IP Media Solutions) Verified mark for interoperability with major broadcast vendors, including Sony, Grass Valley, Evertz, and Lawo. Environmental compliance includes FCC Part 15 Class A, CE, RoHS, and REACH.
