Blackmagic Design Decoder that receives H.264 and H.265 video streams from Blackmagic encoders, ATEM switchers, or cameras and c
FEATURES
The Blackmagic Streaming Decoder 4K is a professional device designed to receive H.264 and H.265 compressed video streams from Blackmagic encoders, ATEM switchers, or Blackmagic cameras and convert them back into SDI and HDMI video. Thanks to its compatibility with RTMP and SRT, it can receive streams from various streaming platforms and ensure secure and reliable transmission.
This decoder supports point-to-point streaming, allowing it to receive video signals from a remote encoder and convert them for local distribution. It is compatible with Blackmagic Cloud Streaming for receiving streams directly from Blackmagic's cloud network. Additionally, it integrates a 12G-SDI reference input, which allows for connecting Tally signals, camera control, and Talkback, ensuring bidirectional communication between the decoder and the cameras.
In terms of connections, the Blackmagic Streaming Decoder 4K offers SDI and HDMI outputs for connecting to professional monitors, switchers, or other video production devices. Like the encoder, it features a 2.2" color LCD display, which allows monitoring of the video stream status and quick access to device settings.
It is designed to be easily integrated into professional racks, thanks to its compact 1/3 rack unit format, which allows multiple units to be mounted in a small space. Furthermore, it includes redundant power with support for AC and DC power, ensuring continuous operation even in the event of failures.
