House Synchronization Input Connectors
These BNC coaxial connectors, illustrated in Figure 4-18, provide the interface for two, house
synchronization signals (i.e., NTSC, PAL, 1080i, 1080P, and 720P only). The house sync inputs
are individually terminated internally. The synchronization signal cannot be daisy-chained from
one routing switcher to another.
