2.4.2Audio Connections

The digital audio inputs and reference input are provided on female BNC connectors. Input signals should be compliant with AES3-id-1995 (unbalanced, 75Ω , 1V peak-to- peak standard output). AES3-id signals are very similar to analog composite video, although dedicated AES3 distribution equipment should be used. If the loop-through BNC connectors are not being used to feed additional equipment, terminate them with a standard 75Ω video terminator.

The main digital output is a female BNC connector. The encoded data is formatted in accordance with the ATSC A/52 Annex B specification, and signal levels are in conformance with AES3-id-1995. The nominal output impedance is 75Ω.

The bypass input is routed to the switched output when the unit is in bypass mode. The unit enters bypass mode when an internal fault occurs or power to the unit is lost. The operator can also select this mode. The key use for this feature is for “hot standby” operation. See Section 4.3 for further details.

2.4.3Vertical Interval Time Code Input

If using SMPTE vertical interval time code (VITC), connect the composite video signal to the VITC In BNC connector using a 75Ω shielded cable. There is a loop-through connection that will require a 75Ω termination if this facility is not being used.

2.4.4Linear Time Code Input

If using SMPTE linear time code (LTC), connect the LTC signal to the LTC input using a male XLR connector.

2.4.5TTL Delay Input

The TTL delay input can be used to control the encoding delay of the DP569 remotely. This port accepts a TTL level signal with an active high-pulse width that corresponds to the desired delay. It may be driven by a video frame sync or related equipment to automatically match the DP569 encoding delay with an associated video delay.

2.4.6Serial I/O (Remote)

The DP569 allows remote control of the unit via the front-panel (RS-232) or rear- panel (RS-485) ports. To place the unit into remote mode, press the Shift button, followed by the left arrow button. Dolby has developed DolbyRemote, a user interface for the Windows operating system. This is supplied with each DP569, and provides a user-friendly control system for most of the unit’s functions. The serial I/O connections can also used for software upgrades.
