The decoder is built with the latest silicon architectures and provides a high level of compatibility with the Selenio SEL-1ENC2 contribution encoder module and other industry encoders. SEL-1ENC2 and SEL-1DEC2 used in pair can deliver a Low Latency of 250ms guaranteed end to end, making a perfect contribution solution for Interview or sports applications. Optimized for Primary contribution applications — including studio-to-studio post production, stadium, surveillance, or satellite uplinks— the Selenio SEL-1DEC2 contribution decoder delivers a full complement of features in a space- and power-efficient footprint, and resets the standard for simplicity in the H.264 era.
