The LiveU LU4000 is designed to handle high-quality video streams, supporting either a single 4K output or four simultaneous HD outputs. This makes the LU4000 a versatile tool for broadcast studios, live event producers, and remote production teams who need to manage multiple video feeds or deliver ultra-high-definition content. Whether you're outputting a single 4K video stream for high-end productions or handling multiple HD feeds for multi-camera setups, the LU4000 delivers professional-grade video with minimal delay.

Featuring HEVC (High-Efficiency Video Coding) decoding, the LU4000 ensures efficient, high-quality video transmission while minimizing bandwidth usage. This makes it ideal for live broadcasts where maintaining video quality over limited bandwidth networks is critical. The HEVC decoding allows broadcasters to receive 4K or HD video streams from remote locations with superior image quality, reducing latency and bandwidth requirements without sacrificing performance.

The LU4000 is optimized for low-latency video output, ensuring that live video streams are delivered in near real-time to studio environments or broadcast control rooms. This is especially important for live news, sports broadcasts, and event coverage, where timing and synchronization are critical for providing an engaging viewer experience.

The LU4000 provides both SDI and HDMI outputs, making it compatible with a wide range of broadcast and AV equipment. This flexibility allows the LU4000 to easily integrate into existing production workflows, connecting directly to switchers, monitors, and other broadcast infrastructure. Whether in a control room, OB van, or studio setup, the LU4000 ensures seamless video output.

The LU4000 receives video over IP networks, allowing for remote production workflows where video feeds from multiple locations can be managed centrally. This makes the server ideal for distributed broadcast setups or remote productions, where video feeds from various locations need to be routed to a central broadcast hub. With its IP-based infrastructure, the LU4000 supports long-distance live streaming with reliable and high-quality video delivery.

For multi-camera live productions, the LU4000 offers synchronized output, ensuring that all video feeds are perfectly aligned for smooth transitions and professional-level production. This makes the LU4000 an excellent choice for sports events, concerts, and multi-camera broadcasts, where timing and synchronization are essential.

The LiveU LU4000 features a web-based management interface, allowing for remote control and monitoring of video streams. This enables production teams to adjust settings, monitor incoming video feeds, and manage operations from any network-connected device, offering flexibility for remote production teams or centralized control rooms managing multiple live feeds.

To ensure reliable performance during critical broadcasts, the LU4000 includes a redundant power supply, ensuring uninterrupted operation even in the event of a power failure. This redundancy is vital for live events, breaking news, and sports broadcasts, where downtime can be costly and disruptive.

The LiveU LU4000 is perfect for broadcast engineers, live event producers, and remote production teams who need a flexible, reliable solution for high-quality video output. With support for single 4K or Quad HD outputs, HEVC decoding, and low-latency performance, the LU4000 is ideal for live sports, concerts, news broadcasts, and studio-based productions where high-quality video delivery and synchronization are critical.
