Cobalt introduces Blue Box Group™ – our all-new line of interface converter boxes that not only offer excellent performance, but also excel to a new level of ease of use and installation practicality. Blue Box can power directly via USB to get its power from video monitors or other equipment. Blue Box HDMI to SDI provides true 3G and HD conversions from HDMI to SMPTE 424M, 292M, or 259M. The HDMI input can also receive and convert DVI-D sources (limited to SMPTE HD formats). Embedded audio on the 2x SDI output can be sourced from the HDMI input (channels 1-8) or from a line-level analog audio pair input. Along with the analog audio embedding offered by BBG H-To-S, this allows an SDI output with embedded audio from DVI-D video sources.
