Teradek Prism 877 4K H.264/HEVC Encoder/Decoder Card for Prism Rack (HDMI)

Teradek Prism 877 4K H.264/HEVC Encoder/Decoder Card for Prism Rack (HDMI) is a modular HDMI processing card designed for installation in a Teradek Prism Rack chassis. Based on the supplied source, it can encode and decode H.264 and HEVC video at resolutions up to DCI 4K60 with 10-bit 4:2:2 color.

The card provides two HDMI ports that can be assigned as inputs, outputs, or loop-through connections. It also supports bidirectional encode/decode operation, allowing one card to handle different contribution, distribution, and return-feed roles within a Prism Rack system.

Why It Helps

Rack-based production systems often need to handle several video paths without filling the installation with separate encoders, decoders, converters, and recorders. The Prism 877 combines those functions in a card designed specifically for the Prism Rack platform.

The two HDMI ports give engineers flexibility when assigning signal paths. A port can be used for source input, decoded output, or loop-through, depending on how the rack is configured for a particular production.

Bidirectional processing is useful when a workflow needs to send one feed while receiving another. The card can therefore support contribution and return-video tasks within the same modular system rather than requiring a separate device for each direction.

The included 256GB NVMe storage and SD card support add local recording options. This can be useful for program backup, confidence recording, event capture, or retaining a local copy of an encoded feed.
