Blackmagic Streaming Decoder 4K

The Blackmagic Streaming Decoder 4K receives H.264 or H.265 streams from Blackmagic Streaming Encoders, ATEM switchers or Blackmagic cameras and converts them to SDI and HDMI video outputs. With return talkback, tally, and camera control support over SDI, it’s ideal for creating point-to-point broadcast links. Its compact design includes a control panel, 2.2" LCD and 12G-SDI/HDMI outputs up to 2160p60.

SDI and HDMI Video Output

The Blackmagic Streaming Decoder 4K transforms compressed video streams back into high-quality baseband video via 12G-SDI and HDMI 2.0 outputs. Supporting H.264 and H.265 over RTMP or SRT, it enables reliable playback of 720p to 2160p60 signals with minimal latency. Whether you’re receiving a remote studio feed, camera stream, or ATEM output, it maintains colour accuracy and frame consistency for professional broadcast use. This makes it ideal for OB trucks, remote studio links, or live event distribution workflows.

Remote Camera Control

With its 12G-SDI reference input and output, the decoder enables bi-directional communication for talkback, tally, and camera control. When paired with a compatible Streaming Encoder or ATEM switcher, the system creates a powerful point-to-point link that allows remote operation of cameras over a single network stream. You can send commands to adjust exposure, iris, gain, focus and more, which is invaluable for solo operators or decentralised productions. This extends traditional control room functions to remote locations without expensive infrastructure.

Configuration and Integration

Configuration is simple thanks to the integrated front panel controls and the 2.2-inch display, or you can manage everything remotely using Ethernet and the Blackmagic Streaming Utility. It integrates cleanly into Blackmagic Cloud workflows, allowing you to receive streams from anywhere with internet access. A REST API is available for automation, letting technical teams scale and manage decoders via HTTP-based applications. Whether you’re building a distributed multi-location broadcast system or adding redundancy to an event, this decoder fits smoothly into modern IP-based infrastructures.

FAQs

What devices can send streams to the Blackmagic Streaming Decoder 4K?

It can receive H.264 or H.265 streams from a Blackmagic Streaming Encoder 4K, ATEM switcher with streaming support, or Blackmagic cameras such as the URSA Broadcast G2 and Studio Camera Pro.

What is the purpose of the reference SDI input?

The 12G-SDI reference input allows for return communication features. When used with a compatible setup, you can enable camera control, tally and talkback over the same IP stream used for video delivery.

Does the Blackmagic Streaming Decoder 4K work as a standalone receiver?

Yes, the Streaming Decoder is completely standalone. It receives a live stream via Ethernet and converts it directly into broadcast outputs without requiring any other Blackmagic devices.

How do I configure the Decoder 4K?

It can be configured via its built-in front panel controls, via the USB-C connection, or remotely over Ethernet using the Blackmagic Streaming Utility software. It also supports REST API for automated environments.
