With a flexible I/O and compact, low-SWaP design, Prism Flex Mk II easily fits into any workflow. Prism Flex Mk II is perfect for placement on a tabletop, camera top, or wedged between your video switcher and audio mixer. Prism Flex Mk II can encode or decode up to 4Kp60 video with stunning 10-bit 4:2:2 image fidelity. The Prism platform supports many common streaming protocols such as TRT, SRT, MPEG-TS, RTSP/ RTP, and RTMP(S), and can be connected to Teradek’s Core Cloud platform for even more flexibility.

- Prism App: The Prism will show up in the menu and can be selected for configuration
ENCODER/DECODER CONFIGURATION
Configure your Prism Flex decoder to receive streams from a Prism Flex encoder.
NOTE: Prism Flex has several streaming modes available such as SRT, RTMP, YouTube, Facebook Live, and now TRT (Teradek Reliable Transport). The following instructions describe how to configure your decoder/encoder using MPEG-TS mode as an example.
1. Connect to the Prism Flex encoder (see previous section) and open the encoder’s web UI.
2. Open the Streaming menu, then select MPEG-TS as the streaming mode.
3. Select a protocol, then ensure the Prism decoder is configured to receive the stream using the correct protocol:
- TCP → TCP
- TCP Server → TCP Pull
- UDP → UDP
- Multicast → Multicast
Encoder Web UI
4. Enter the destination IP address, then confirm the port is set as the default 9710.
5. Connect to the Prism decoder (see previous section) and open the decoder’s web UI.
6. Open the Ingest menu, then select MPEG-TS as the ingest mode.
7. Enter the protocol, ensuring the selected protocol matches the Encoder’s protocol configuration (see step 3). Confirm the port is set as the default 9710.
CONNECTING TO CORE
Core allows Prism Flex to be remotely controlled, utilize bonding protocols (Teradek Bonding Protocol and TRT) across multiple internet connections, and split the stream across multiple destinations.
