Blackmagic Design SDI Expander 8x12G

Overview

The Blackmagic Design SDI Expander 8x12G is a 1 RU bidirectional SMPTE 2110 IP converter built to integrate conventional 12G-SDI equipment into high-bandwidth 100GbE broadcast and production systems. Designed for hybrid SDI/IP facilities, it can simultaneously convert eight independent 12G-SDI inputs to SMPTE 2110 IP while also converting incoming SMPTE 2110 IP streams back to eight 12G-SDI outputs. This allows broadcasters, studios, mobile units, and technical facilities to bridge existing SDI infrastructure with modern IP workflows without sacrificing channel density or operational flexibility.

Built for demanding live production and broadcast environments, the unit supports up to 16 channels of simultaneous 10-bit 4:2:2 video conversion at resolutions up to UHD 4K60. Dual 100GbE QSFP28 connections provide SMPTE ST 2022-7 redundant streaming for dependable signal transport, while support for SD, HD, and Ultra HD formats with automatic detection helps simplify deployment across mixed-format systems. With embedded audio support, NMOS-based control, and a front-panel LCD for status and monitoring, the SDI Expander 8x12G is designed to serve as a practical and reliable bridge between legacy SDI devices and next-generation IP networks.

Core Features

• The converter supports simultaneous bidirectional operation, converting eight 12G-SDI inputs to SMPTE 2110 IP while also converting SMPTE 2110 IP streams back to eight 12G-SDI outputs.
• It can handle up to 16 channels of simultaneous 10-bit 4:2:2 video conversion for dense hybrid SDI and IP production workflows.
• Dual 100GbE QSFP28 connections support SMPTE ST 2022-7 redundancy for resilient transport across professional IP systems.
• The unit supports SD, HD, and Ultra HD formats up to 4K60 with automatic format detection to simplify integration in mixed-standard facilities.
• Up to 16 channels of embedded audio are supported per 2110 IP video stream for comprehensive audio and video transport.
• A 2.2" front-panel LCD with integrated control knob and buttons provides monitoring and local configuration access.
• Dedicated RJ45 connectivity supports NMOS-based external control, while USB-C is available for firmware updates and local setup.
• Dual IEC C14 power inputs provide redundant power for improved reliability in continuous professional operation.

Hybrid SDI and IP Integration

The SDI Expander 8x12G is designed for facilities that need to connect established SDI hardware to SMPTE 2110 infrastructures. This makes it especially useful in transitional environments where routers, switchers, recorders, and monitors may still rely on SDI even as core signal transport moves to IP.

High-Density 4K Conversion

With support for eight inputs, eight outputs, and up to 16 simultaneous channels of conversion, the unit offers substantial throughput in a compact 1 RU chassis. Its ability to process UHD 4K60 10-bit 4:2:2 video makes it well suited to high-end broadcast, live event, and studio workflows.

Monitoring and Control

The built-in 2.2" LCD, control knob, and buttons allow operators to view system information and manage settings directly from the front panel. Audio confidence monitoring is also supported via the built-in speaker and headphone output, while NMOS control over RJ45 allows integration into managed IP production systems.

Reliable Broadcast Operation

Dual 100GbE connectivity with ST 2022-7 redundancy and dual AC power inputs help the expander meet the reliability demands of professional broadcast environments. Together with automatic format detection and broad standards support, these features make it a practical choice for dependable long-term deployment.
