Teradek Prism 877 4K H.264/HEVC Encoder/Decoder Card for Prism Rack (12G-SDI)

Teradek Prism 877 4K H.264/HEVC Encoder/Decoder Card for Prism Rack (12G-SDI) is a modular video-processing card built for the Teradek Prism Rack chassis. Based on the supplied source, it supports H.264/AVC and H.265/HEVC encoding and decoding at resolutions up to DCI 4K60 with 10-bit 4:2:2 color.

The card provides two 12G-SDI ports that can be configured for input, output, or loop-through operation. It can be deployed as an encoder or decoder, while bidirectional encode/decode operation is available with an optional license.

Why It Helps

The Prism 877 gives broadcast engineers a flexible way to add 12G-SDI encoding or decoding to a Prism Rack without installing a separate standalone appliance. The modular format keeps processing, recording, and signal routing inside one rack-based platform.

Its two 12G-SDI ports can be assigned according to the job. A port may receive a source, provide a decoded output, or pass the incoming signal through to another device. That flexibility is useful when the same rack needs to support different production layouts from one event to the next.

Support for DCI 4K60 and 10-bit 4:2:2 video gives the card enough processing headroom for modern broadcast and live-production signals. H.264 remains available for established delivery paths, while HEVC provides a more bandwidth-efficient option for high-resolution contribution.

The built-in 256GB NVMe storage and full-size SD card slot also provide local recording options. Engineers can retain a copy of the stream for backup, review, compliance, or later transfer without adding a separate recorder to the rack.
