Teradek has introduced a new 4K HDR rack-mount HEVC codec system, Prism, and a new professional live streaming app for iOS, Airmix.


Teradek: The new Prism 2RU HEVC/AVC encoder/decoder

Prism is claimed to make it “more affordable than ever to upgrade your IP video workflow to industry-leading, low-latency 4K HDR video”. It is designed for mission-critical applications, while its adaptability makes it suitable for IP video deployments of any size and complexity.

There are two models, in 1RU and 2RU high-density formats, offering 10-bit, 4:2:2, 4K HDR HEVC/AVC encoding and decoding. There is room for up to nine blades in the 2RU chassis or three blades in 1RU, allowing users to combine any encoder or decoder cards needed for a specific workflow.

Prism supports the Secure Reliable Transport protocol to ensure it can deliver high-quality, low-latency streaming video, even during periods of severe network congestion. It also supports other protocols, including RTMP(S) and MPEG-TS.

The 2RU version can include redundant power supplies, while both have dual gigabit Ethernet ports. Users can configure the device locally from a phone or desktop, or remotely from a web browser through Core, Teradek’s (optional) cloud-based management platform. Core can deliver to multiple formats and platforms, handling transcoding, routing, management and archiving - it can also enable Prism to do IFB.

The Airmix iPad app allows users to transform a basic single or multi-camera live production into a polished live stream. It includes most features seen in a hardware video switcher, such as: the ability to stream with up to ten media sources at a time including cameras, network video and pre-recorded files; support for up to 1440p60 streaming resolution; PiP and Multiviewer functionality; integrated audio mixer and graphics editor; chroma key compositing; GIF and PDF support; built-in customisable scoreboards and overlays; and instant replay and slow motion for sports. It also streams to any online video platform, and has integrated YouTube, Facebook and Twitch chat monitoring.

It uses a project-based workflow with quick access presets. It can support Tally (with the Airmix Remote app), can record to the iPad instead of streaming, or do both simultaneously, with manual camera control for iOS devices (bitrate, resolution, focus and exposure), and offers multiple video transitions including dissolve, swipe and scale. It includes RTSP remote video ingest.

The iPad app is free to download, but there is a basic subscription of $29.99. It replaces Teradek’s Live:Air Action app, but existing users can have both installed at the same time, although Live:Air Action will no longer be supported.
