Transport
This control sets the video transport protocol for the SDI output. Select from:
• Auto - Automatically selects output transport, based on input format.
• Up to 2K format, Auto chooses the most efficient transport (i.e. auto defaults
to 1 x 3G rather than 2 x 1.5G).
• For UltraHD/4K the Auto setting does not apply. 12G/6G 1-wire or 2SI is
selected with the 4K Transport control.
• Dual Link - Forces (SMPTE 372M) output, using SDI 1 and SDI 2 in concert.
• 3Gb - Forces (SMPTE 424M) output using a single-link transport.
4K Transport
Select the UltraHD/4K output transport from:
• Quadrants 2-Wire
• Quadrants 4-Wire
• 12G/6G 1-Wire
• SMPTE 2Si
• 4K Quarter 1-Wire - Down-converts 4K to 2K, and UltraHD to HD.
NOTE: The 4K Transport setting also affects the Io 4K Plus HDMI output signal, even if the
SDI inputs are not being used. A 12G/6G 1-Wire or SMPTE 2Si setting is required for
UltraHD/4K HDMI output. Other 4K Transport settings will down-convert HDMI
output to HD or 2K.
