Video Production Switcher with 6-Channel SMPTE 2110 and 2-Channel 3G-SDI

Support modern IP network video workflows with robust performance and unprecedented flexibility

As the broadcast industry continues its shift from traditional SDI infrastructure to IP-based workflows, the need for standardized, reliable transport of video, audio, and data over IP networks has become critical. While IP video transport has existed for years, it was the Society of Motion Picture and Television Engineers (SMPTE) that addressed the industry’s demand for interoperability by formalizing the SMPTE ST 2110 standard. This suite of standards defines how to transport professional media over IP networks in real time, enabling broadcasters to break free from the limitations of point-to-point SDI cabling and adopt more scalable, flexible, and cost-effective production environments.

At the same time, software-driven production systems have rapidly advanced, displacing traditional hardware-based switchers and processors. Among these, vMix has emerged as one of the most versatile and powerful software applications for live video mixing, graphics, replay, recording, and streaming.

The Switchblade LPU4 for SMPTE 2110 bridges these two transformative trends by bringing the full capabilities of vMix into the IP broadcast domain. The LPU4 is a robust, all-in-one live production platform designed for professional multi-camera switching, real-time graphics, instant replay, ISO recording, and live streaming—all powered by vMix Pro software.

Built around the high-performance Bluefish444 Kronos Optikos ST IP video board, the LPU4 offers full support for SMPTE ST 2110 workflows, providing broadcasters with high-quality, low-latency IP video input and output. With powerful processing, generous storage, and seamless IP integration, the LPU4 empowers broadcasters to take advantage of next-generation IP infrastructure without sacrificing the flexibility and efficiency of software-based production.
