SD & HD-SDI Input board.
The SD & HD-SDI Input board is available for Master Four and extends the input compatibility with two Serial Digital Interface inputs (SDI) that comply with SMPTE259M and SMPTE292M standards.

By using a SDI interface between your source and display, the video signal remains in the digital domain, avoiding quality-degrading digital-to-analog and analog-to-digital conversion steps, and thereby retaining the best possible picture clarity.

The compatible input resolutions are: 480i-60, 576i-50, 720p-60, 1080i-50, 1080i-60, 1080p-24, 1080p-25 and 1080p-30.
