PD3-S20 - Dual-streaming AVoIP LED controller with 20 Ethernet outputs, up to 13 million pixels, 4K @ 60 Hz primary stream, ultra-low latency of 2 ms via InstSight compression

Dual-streaming AVoIP LED controller with 20 Ethernet outputs, up to 13 million pixels, 4K @ 60 Hz primary stream, ultra-low latency of 2 ms via InstSight compression

The PD3-S20 is a dual-streaming LED controller and AVoIP processor, designed for professional environments requiring advanced, decentralized management of audiovisual content. Like the PD3-S10, it has no physical video inputs: it receives signals exclusively over an IP network, via an Ethernet port and a 1 Gbps optical port, compatible with RTSP, RTP, RTCP, and ONVIF protocols. This allows the PD3-S20 to directly decode video streams from distributed encoders, IP cameras, and media servers, even if they are located far from the LED walls being controlled.

The device simultaneously transmits two video streams: a high-quality primary stream, compressed with the proprietary InstSight algorithm, and a standard-quality secondary stream, based on H.264 / H.265. This dual-streaming architecture enables efficient content distribution with minimal latency (up to 2 ms) and reduced network bandwidth impact. The PD3-S20 can handle up to 24 video layers in Full HD resolution and supports a primary layer up to 4K @ 60 Hz, with nanosecond synchronization between nodes to ensure perfectly smooth, tear-free viewing.

Designed for complex and distributed installations, such as control rooms, conference centers, airports, and data centers, the PD3-S20 enables centralized content management even in multi-site scenarios, thanks to VLAN compatibility and the ability to configure each node as an autonomous control center. The visual management interface allows real-time content monitoring, free layout configuration, preset management, and remote control, even via tablet.

In a control room, for example, it's typical to have a large screen, with the need to open PiP windows, manage multiple presets for different display types, and integrate signals from heterogeneous sources (IP cameras, computers connected to CCTV software, remote servers). The Pixelhue PD3-S10, together with the PD3-2K or PD3-4K models belonging to the same ecosystem, allows centralized management of all these flows from a single location, including direct control of up to 8 computers via the KWM function.

On the hardware front, the PD3-S20 is equipped with 20 Ethernet ports for direct loading of LED walls without the need to switch between a separate LED controller, with a maximum capacity of 13 Mpixel. It supports 8/10-bit 4:4:4 RGB output, even irregular LED screen configurations, custom EDID management, and a wide range of refresh rates. It also includes audio inputs and outputs (MIC / line IN, line OUT), with support for AAC and G.711 formats, as well as control connectors such as RS232, RS485, IR, I/O, and RELAY.
