The Mini Converter Heavy Duty - SDI to Analog from Blackmagic Design is an extremely rugged device that accepts any SD, HD, or 3 Gb/s SDI input – redundant connections are supplied, for automatic switch-over in case of failure – and outputs an HD/SD component, NTSC/PAL (composite), or S-Video signal. You can also choose to de-embed two channels of SDI audio for the balanced AES/EBU or L/R analog audio outputs.
