SDI IN
A 75 Ω BNC connector provides a serial digital video
input to the unit. See Chapter 4, Operating the
Equipment Locally, Video Input Option for the types of
video and selection method. This input is terminated in
75 Ω .
The serial input supports error detection and handling (EDH) as defined by
the specification SMPTE RP 165-1994, ‘Error Detection Checkwords and
Status Flags for Use in Bit Serial Digital Interfaces for Television’.
For more information about EDH refer to Annex I, EDH Capability for E57xx
Encoders.

H SYNC
Studio Black and Burst should be fed to the 75 Ω BNC
connector (H SYNC). This will then genlock the
Encoder to the Studio system. This method may be
required with some audio formats, or for locking
Encoders to an evolution 5000 Multiplexer. For details
on the genlocking system see Annex F, Audio Modes.
