HDMI 4K HDCP 2.2 compliant splitter with in-built down-scaler, audio breakout and EDID management


The Blustream SC12SP is a HDMI 4K splitter with in-built down-scaler, designed for installations in which a single 4K video source needs to be distributed to multiple displays that support different maximum video resolutions. The SC12SP allows those displays only capable of supporting lower video resolutions to receive 4K video while still showing maximum original 4K resolution on the higher-definition display. The SC12SP supports down-scaling of 4K video to various lower resolution video formats, features audio breakout, advanced EDID management and is HDCP 2.2 compliant.
