Overview
Streaming Decoder 4K
Live Stream to YouTube, Facebook, X and More
If you need to create a broadcast streaming link, then you can use the Blackmagic Streaming Decoder. It will receive and convert a H.264 or H.265 stream to SDI video. It even supports tally, talkback and camera control back to the camera. Professional streaming decoder lets you receive an ATEM or Blackmagic camera H.264 stream and convert it back to SDI and HDMI video. Includes return tally and control, plus Blackmagic Cloud streaming.
Create Point to Point Internet Based Broadcast Links
Blackmagic Streaming Encoder can also build internet broadcast links with the Blackmagic Streaming Decoder 4K. The Blackmagic Streaming Decoder 4K receives the H.264 or H.265 stream from the Blackmagic Streaming Encoder and converts it to SDI and HDMI video. This means you can send video point-to-point between remote locations. The Blackmagic Streaming Decoder also has a 12G-SDI "reference" input that lets you connect SDI tally, camera control plus talkback and send it back up to the encoder end. Imagine setting up a central control room with remote streaming from cameras with full tally, talkback and camera control on the remote cameras! Everyone is remote, but still working together.
Includes Blackmagic Streaming Utility
The Blackmagic Streaming Utility software manages multiple streaming encoders and decoders so you can update settings and software. Simply plug the Blackmagic Streaming Encoder directly into the front of its USB connection, or connect it using Ethernet so you can configure it remotely, which is useful when managing multiple remote sites. The user-friendly menus and controls make it incredibly simple to set up a live event, so you can get started fast! Plus the front panel LCD menus have the same settings and controls. You can even load additional services for a Blackmagic Streaming Decoder. The Blackmagic Streaming Utility software is free to download and runs on both Mac and Windows.
Control and Color Balance Remote Cameras
Most Blackmagic Design cameras support camera control, talkback and tally from an ATEM switcher via an SDI control protocol. Control is for all cameras and is embedded into the ATEM SDI outputs, and then you select the specific camera number on the camera. Imagine changing ISO, tint, iris, focus, zoom with tally and talkback all remotely! This also works for cameras with built-in streaming. To do this, you connect the Blackmagic Streaming Decoder’s REF input to the ATEM switcher's SDI output. You can also use the Blackmagic Streaming Encoder for cameras without streaming. Control is embedded into the SDI monitoring output of the Streaming Encoder, to connect to the Blackmagic camera’s SDI input.
Compact 1/3rd Rack Mount Design
Both the Blackmagic Streaming Encoder and Blackmagic Streaming Decoder use the modular Teranex Mini design allowing rack mounting. It has a built-in AC power supply and a 4-pin 12V DC connection for backup or battery operation. The ultra-portable design is only 5.5 inches wide, allowing you to mount three in a single rack unit for simultaneous streaming to multiple independent services. That means you can combine Blackmagic Streaming Encoder with an ATEM 1 M/E Constellation switcher for a live production and streaming solution in a single rack unit! Plus the front panel features a USB connection, allowing you to walk up and connect a computer for quick local setting changes.
