Introduction
9033 Functional Description
9033 Functional Description
Figure 1-1 shows a functional block diagram of the 9033. The 9033 includes a
full 16-channel audio embedder that receives either 8-pair AES or 8-channel
balanced analog audio inputs. The 9033 can also route any audio source to an
8-pair AES output. The 9033 also handles AFD code insertion and transfer of
Dolby
® metadata.
(9033-DEC only) The 9033-DEC also performs Dolby ® E and Dolby ®
Digital™ decoding and decoded channel routing.
(9033-SD only) The 9033-SD is functionally equivalent to the 9033, 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. 1-14) for user interface
descriptions.
9033 Input/Output Formats
The 9033 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). (9033-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 9033. The practical input/output complement is determined by the par-
ticular Rear I/O Module used with the 9033. Refer to 9033 Rear I/O Modules
(p. 1-16) for more information.
