Leitch X75 HD - Video Path

Appendix F: Specifications
Video Path
When a block is inserted, the FS phase or SD-ARC will be compensated to
maintain output, and the H/V phases won't change. If the SDNR is inserted,
the propagation delay may not change or may add one extra I-frame,
depending upon the FS phasing. The total FS+SDNR delay will be less than
1.5 I-frames.
If the SD-ARC is inserted, the propagation delay will add an extra 0.5 to 1.5
I-frames, depending upon FS phases and SD-ARC/HD-Dn phase settings.
If the strobe is inserted, the propagation delay most likely will not change; if a
delay-line is inserted, the propagation delay will add an extra 0 to 4 I-frames,
depending upon the delay line settings.
If a keyer is inserted, the propagation delay most likely will not change.
