Prism Duplex Quick Start Guide

Updated on Nov 19, 2024

The Prism Duplex (SDI and HDMI) is an ultra-flexible H.264/HEVC encoder/decoder solution for enterprise, broadcast, live production, and public safety applications. Prism can encode or decode up to 4KDCIp60 video with stunning 10-bit 4:2:2 image fidelity. Boasting 512GB of onboard NVME, Prism allows a new level of recording management with built-in camera-to-cloud capabilities. Prism Duplex cards can be both an encoder or decoder through a software switch and the encoder side supports the decode license expanding density.

PHYSICAL PROPERTIES

RACK SYSTEM 2RU (HDMI/SDI)

RACK SYSTEM 1RU (HDMI/SDI)

DUAL GIGABIT ETHERNET PORTS
Prism features two independent Ethernet ports (Wired 1, Wired 2). These two Ethernet ports connect to an internal switch inside the chassis (one per Ethernet port), allowing an encoder/decoder card to have two addressable ports as well as two different networks. For example, one port can connect to an internal network for configuration while the other port can connect to a separate network for streaming.

Internet routing is configured automatically, so either port can be used to stream out over a WAN. If both connections have Internet access, the Wired 2 interface takes priority over Wired 1. Both interfaces can be configured for DHCP or static addresses independently of one another.

NOTE: Only use one Ethernet port at a time.

1x IEC Cable (USA)

PRISM ENCODER/DECODER CARDS

1x Prism 877 Card
1x HDMI or SDI backplate

POWER AND CONNECT

Using the Prism Duplex as an Encoder

Connect HDMI or 12G/3G/HD/SD-SDI video sources to the inputs of the corresponding card: HDMI IN or SDI 1
Connect the other end of the cable to your source.
Connect one Prism’s 10/100/1000 Ethernet ports to a network switch or router using an Ethernet cable.
Connect power to Prism using the included IEC cable (USA only). Connect a second cable if your device includes a supplemental power supply (optional).
Press the Power button (B) to turn on the unit.
Using the menu joystick, navigate to the Network Settings menu on the front panel. Select a Wired interface, then verify that the IP Mode is set to DHCP. Once Prism is connected to a network, the front panel will display the current assigned or configured IP address for both Ethernet ports.

Using the Prism Duplex as a Decoder

Connect HDMI or 12G/3G/HD/SD-SDI video sources to the outputs of the corresponding card: HDMI Out or SDI 1/2
Connect the other end of the cable to your destination.
Connect one Prism’s 10/100/1000 Ethernet ports to a network switch or router using an Ethernet cable.
Connect power to Prism using the included IEC cable (USA only). Connect a second cable if your device includes a supplemental power supply (optional).
Press the Power button (B) to turn on the unit.
Using the menu joystick, navigate to the Network Settings menu on the front panel. Select a Wired interface, then verify that the IP Mode is set to DHCP. Once Prism is connected to a network, the front panel will display the current assigned or configured IP address for both Ethernet ports.

GET ONLINE

Use the front panel interface or the web UI to configure Prism encoders and decoders.

Connect via Ethernet

Using the menu joystick, navigate to the Network Settings menu on the front panel. Select a Wired interface, then verify that the IP Mode is set to DHCP.
Once Prism is connected to a network, the front panel will display the current assigned or configured IP address for both Ethernet ports.

IP MODES
DHCP mode is the default setting. In DHCP mode, Prism cards will request an IP address and all other network configurations from the network’s server. The IP address can be found by pressing the menu joystick until it’s displayed on the front panel. When set to Static mode, you will need to manually configure the IP address and all other network configurations from either the front panel
or the Prism web UI.

Access the Web UI

After connecting Prism to a network, you can access the web UI and configure stream destinations, encoder parameters, and other settings.

Press down on the cards’ menu joystick (C) to display Prism’s IP address on the front panel.
Enter the IP address in your web browser’s navigation bar, then enter the default login information.
Enter the default password. NOTE: The default password is formatted as product + serial, where "product" is the lowercase product name (prism), and "serial" is the last 5 digits of the device's serial number. For steps on how to create a unique security password, go to the System Configuration section of the Prism User Manual.

ENCODER OR DECODER SELECTION

The Prism Duplex is ready to use as either an encoder or a decoder immediately upon setup. Additionally, Prism Duplex supports the Decode License.

Navigate to the IP address of the Prism.
Under System Settings select Codec Mode
Change the Codec Configuration to be Encoder or Decoder

PRISM APP

The Prism App allows you to remotely configure all of Prism’s settings while monitoring your stream’s destination, bitrate, bonding status, and resolution to ensure you maintain a stable stream. The Prism App is available for iOS devices.

MAIN DISPLAY
• Main Screen - Displays the preview, streaming destination, audio and video bitrates, and resolution of your livestream.
• Link/Unlink iOS Device - Tap the Link/Unlink iOS tab to enable/disable the use of your cellular phone’s data as an Internet connection.

STATS
Tap the Stats button at the top of the screen to display Prism’s serial number, current audio and video bitrates, runtime, recording status, IP address, and network.

SETTINGS
Tap the Settings button to configure the following options:
• Streaming - Configure your streaming method and destination
• Recording - Enable recording and select a media storage option
• Audio/Video - Adjust the Video and Audio input settings
• Network - Choose a method of connecting to the Internet
• System - View the model and serial number of your device, or rename the Prism.

CORE

Prism can be remotely accessed, configured, and controlled using Teradek’s Core Cloud management and routing service. With Core, you can:

• Bond multiple Internet connections, increasing your broadcast’s bandwidth and reliability.
• Remotely control Teradek encoders, decoders and bonded systems from anywhere in the world.
• Stream to multiple destinations.

Visit https://corecloud.tv to learn more.

CONNECT PRISM TO CORE

1. From the web UI, select Cloud Services then click the Link this Device tab.

2. Log in to Core: Enter your credentials to link Prism to your Core account, then click Next.
Link with Code: Copy the authorization code generated for your Prism, then follow the instructions provided.

3. Once a connection is established, you can configure Prism from either the Prism UI or Core dashboard.

BASIC ENCODER TO DECODER CONFIGURATION

Prism has several streaming modes available such as Teradek Cloud (Bonding Protocol), SRT, WebRTC, HLS, RTMP, TRT, RTSP, RTP Push, and RIST. The following instructions describe how to configure your decoder/encoder using MPEG-TS in TCP mode on a LAN as an example.

1. Connect to the Prism encoder (see previous section) and open the encoder’s web UI.

2. Open the Streaming menu, then select MPEG-TS and leave as default as the streaming mode and press save. Note the Server Port (5000 by default)
