NAB2025

Blackmagic Design unveiled “Stream Router” and “ATEM Cloud,” new streaming services for the Blackmagic Cloud, at NAB 2025.
Stream Router
The Stream Router functions as a cloud video router, and the ATEM Cloud functions as a cloud switcher. Until now, Blackmagic Cloud has mainly been used as a post-production tool, providing collaborative editing and video file sharing via the cloud. The addition of the newly announced Stream Router and ATEM Cloud suggests that the range of use for Blackmagic Cloud will expand to the field of live production.
Cameras such as the Blackmagic PYXIS 6K, Blackmagic URSA Broadcast G2 and the Blackmagic Camera app for iPhone and Android can upload data directly to the Blackmagic Cloud. The new streaming service uses the SRT (Secure Reliable Transport) protocol to send streams from these cameras to the cloud, allowing input/output allocation and switching operations to be performed on the cloud via the Stream Router. In addition, for cameras and other video equipment that do not support SRT streaming, the new Blackmagic Streaming Encoder can be used to send video to the cloud via SRT.
By implementing the functions of the currently available video router Blackmagic Videohub and video switcher ATEM on the cloud, it will be possible to use functions such as specifying the output destination of received video, as well as traditional switching and camera control, even in environments where the hardware does not exist.

Specifically, the system uses the Stream Router on the Blackmagic Cloud portal site to receive encoded video from various cameras and specify the desired output destination. Output destinations can include the ATEM Cloud cloud switcher, the DaVinci Remote Monitor application that can be used on computers and smartphones, and the new Blackmagic Streaming Desoder. Direct streaming from the cloud switcher to YouTube is also possible, and in addition to one-way streaming, tally signals and camera control signals can also be sent back to the camera.
ATEM Cloud
As a cloud switcher, ATEM Cloud can be operated using the ATEM Software Control in the same way as the conventional hardware version. In terms of functionality, like the ATEM switcher, it offers video switching with transitions, PinP (picture-in-picture) compositing, chromakey compositing, and more. It is also compatible with hardware control panels for ATEM switchers, such as the ATEM Micro Panel and ATEM Camera Control. The inputs and outputs of ATEM Cloud are configured within the Stream Router, and the multiview output and program output can be reused as input sources for the Stream Router. With this system, it is possible to envision operations such as switching and monitoring large-scale live productions using a laptop from a hotel room, for example.

The official release date and usage fees for the service have not yet been decided, but it is expected to greatly expand the possibilities for future cloud-based video production workflows.
