9034-OM (V4.1) 9034 PRODUCT MANUAL 1-5
Introduction
9034 Functional Description
9034 Functional Description
Figure 1-1 shows a functional block diagram of the 9034. The 9034 frame
synchronizer includes a full 16-channel audio embedder that receives either
8-pair AES or 8-channel balanced analog audio inputs. The 9034 also handles
AFD code insertion and transfer of Dolby
® metadata.
(9034-DEC only) The 9034-DEC also performs Dolby ® E and Dolby ®
Digital™ decoding and decoded channel routing.
(9034-SD only) The 9034-SD is functionally equivalent to the 9034, except
that it is limited to SD analog video input, processing, and associated controls.
Note: Some of the functions described below are available only when using the
DashBoard™, or Cobalt
® OGCP-9000 or OGCP-9000/CC Control Panels
user interfaces. Refer to User Control Interface (p. 1-16) for user interface
descriptions.
9034 Input/Output Formats
The 9034 provides the following inputs and outputs:
• Inputs:
•
Y/Cmpst IN , Pr/C IN , Pb IN – analog composite/component video
inputs
• AES I/O (1-4) – user-switchable as AES inputs or AES outputs
• AES IN (5-8) – dedicated AES inputs
• AN-AUD IN (1-8) – balanced analog audio inputs
• Outputs:
• SDI OUT – two dual-rate HD/SD-SDI buffered video outputs
•
AES OUT (1-8) – dedicated AES outputs
•
AES I/O (1-4) – user-switchable as AES inputs or AES outputs
•
DOLBY META – RS-485 Dolby ® metadata output (extracted from
input video). (9034-DEC only) RS-485 Dolby ® metadata output
can consist of input video or Dolby ® decoder metadata output.
Note: The input/output complement listed above represents the maximum capability
of the 9034. The practical input/output complement is determined by the par-
ticular Rear I/O Module used with the 9034. Refer to 9034 Rear I/O Modules
(p. 1-18) for more information.
