Description:
The SDI out scale configuration controls the format of the SDI output banks,
SDI and SDIALT. Each bank has a unique configuration allowing simultaneous HD
and SD output. When set to OFF, the native resolution is output. When set to SD,
the output is down-scaled dependent upon the source format. If the source
format is 50Hz, the output will be down-scaled to PAL (720x576@50Hz). If the
source format is 59.94 Hz, the output will be down-scaled to NTSC (720x480@59.94Hz).
Please note that there will be a 1 frame delay in the down-scaled output. Audio
synchronization is accounted for automatically on scaled outputs.
