HDC-8223A(-S) User Guide (v4.0) Before You Begin • 13
Before You Begin
The HDC-8223A(-S) is a monitoring quality down-converter that also offers optional audio support.
The down-converted SDI and analog composite signals are selected through four, 2:1 crosspoints
allowing any combination of SD-SDI or analog composite (CVBS) outputs on the four card processed
video outputs. With the R2C-8223A full rear module, four analog audio channels are available.
Overview
The HDC-8223A(-S) also provides ARC processing and timecode/closed-captioning conversion from
packet-based timecode formats and CEA608/708 HD formats to SD VITC-based (waveform)
timecode and line 21 closed captioning (available on both SDI and analog video outputs).
The HDC-8223A(-S) provides the following inputs and outputs:
•3G/HD/SD SDI IN A / SDI IN B – two dual-rate SDI inputs (GUI-selectable or basic failover)
•PROCESSED VIDEO OUT (1-4) – via four independent 2:1 GUI-selectable crosspoints, each of the
four BNC outputs can independently be set as SDI or analog composite (CVBS) outputs
•RLCK OUT (1-4) – four 3G/HD/SD-SDI reclocked buffered video outputs
•AN-AUD OUT (1-4) – four balanced analog audio outputs (R2C-8223A rear module only)
Video Subsystem Overview
The HDC-8223A(-S) features a downconverting scaler, video proc, and user-adjustable aspect ratio
control and zoom control. The HDC-8223A(-S) video subsystem also provides the functions
described below.
Rear Modules
The HDC-8223A(-S) physically interfaces to system video connections at the rear of its frame using a
rear module.
All inputs and outputs shown in Figure 3 enter and exit the card via the card edge backplane
connector. The rear module breaks out the HDC-8223A(-S) card edge connections to BNC and other
connections that interface with other components and systems in the signal chain.
For More Information on...
• the supported rear modules, refer to “Installing a Rear Module”.
Input Select
The HDC-8223A(-S) can select from either of two 3G/HD/SD-SDI inputs using either manual control,
or settings that provide failover to the alternate secondary input. (Failover is simple signal presence
check only.) An input Allowed Rasters and Allowed Frame Rates filter allows inputs to be filtered
(screened) for only user-allowed raster sizes and frame rates, with disallowed raster/rates being
rejected as an input (input unlock). Reclocked copies of the selected program video SDI input can be
outputted by the card.
Video Processor
The HDC-8223A(-S) provides full color processing control (luma gain and lift, chroma saturation, and
color phase) of the output video.

14 • Before You Begin HDC-8223A(-S) User Guide (v4.0)
Scaler Function
The scaler function provides down-conversion to SD from multiple standard SD, and 3G/HD video
formats and multiple frame rates, with auto-format detect/down-conversion of SMPTE
424M/292M/259M formats. Color framing is preserved on CVBS outputs for all conversions.
The scaler function also provides aspect ratio conversion that provides a choice from several
standard aspect ratios. User-defined settings allow custom user-defined H and V aspect ratio
control, as well as pan/tilt control. Reticule insertion provides safe action area marking as well as
other reticule functions and patterns.
Frame Sync (HDC-8223A-S Only)
This option provides for frame sync control using either one of two external REF IN 1, REF IN 2
reference signals distributed with the openGear frame, or the input video as a frame sync
reference.
This option also allows horizontal and/or vertical offset to be added between the output video and
the frame sync reference.
Frame sync can select from either of two card frame reference sources, or free-run input video
sync. In the event of input video loss of signal, the output can be set to disable video, go to black, go
to an internal test signal generator pattern, or freeze to the last intact frame (last frame having valid
SAV and EAV codes).
An internal test signal generator provides a selection of 10 standard patterns such as color bars,
sweep patterns, and other technical patterns. The generator output can be invoked upon loss of
program video input, or applied to the program video output via user controls.
Timecode Processor
As illustrated in Figure 1, this function provides for extraction of timecode data from the input
video, and in turn re-insertion of timecode data into the output SDI or analog composite. In this
manner, timecode data can be preserved, even after format conversion. The function can monitor
the SDI video input of the card for supported timecode formats and convert the timecode to either
or both ATC_VITC or VITC waveform (with selectable odd/even field line number control). ATC_VITC
and VITC waveform outputs are available on SD-SDI outputs; VITC waveform only is available on
CVBS outputs.

Closed Captioning Processor
This function provides support for closed captioning setup. When receiving HD-SDI, both CEA 608
and CEA 708 are supported, with CEA 608 and CEA 708 (containing CEA 608 packets) converted to
line 21 closed captioning on outputs down-converted to SD.
Ancillary Data Processor
This function provides VANC/HANC ancillary data “bridging” to extract ATC packet data from the
incoming SDI signal, preserve the ANC data packets, and re-embed the packets post-scaler in the
SDI signal. User DID/SDID locations can be specified and then extracted and preserved for bridge
reinsertion. Insertion controls provide for inserting the ANC data in VANC, HANC, or C-space.
Color Corrector
This option converts the YCbCr SDI input video to the 4:4:4 RGB color space (where the color
correction is applied), and then back to YCbCr SDI on the output. Controls are available to adjust
each RGB level independently for both white levels (gain) and black levels (offset). Gamma can also
be independently adjusted for each RGB channels. Various controls can be ganged to provide
adjustment for all three color channels simultaneously.
AFD ARC Processor
The AFD processor allows extracted Aspect Ratio Control (ARC) data from the input video and
provides:
• H/V cross-conversion matrix in which a received code directs a same or other user-selectable
alternate H/V ratio on the output for any of several H/V ratios.
• Directs scaler automatic active ARC in response to received and/or converted ARC code (Scaler
Follows ARC).
The input video is checked for ARC formats and can be set to provide a trigger upon when a
selected ARC format is received. Received H/V codes can also be applied through an H/V conversion
matrix that allows alternate H/V ratios for a given received input code. In conjunction with a
user-accessible cross-matrix table, the received code then in turn directs any of several
user-selectable H/V settings to be inserted on the output video.
AFD can be rejected for input consideration. The selected output H/V ratio can be set to
automatically apply this aspect ratio to the program video via the card ARC scaler.
Character Burn-in Functions
User text and timecode (as selected using the timecode function) can be burned into the output
video. Burn-in attributes such as size, position, background, color, and opacity are
user-configurable. Two discrete character burn strings can be inserted on the output video, with
each string inserted as static text and/or insert only upon loss of signal.
Audio Overview
The audio processor operates as an internal audio router. This function chooses from the following
inputs:
• 16 channels of embedded audio from the SDI video input (1-to-1 routing to SDI output)
• 16 discrete tone generators (with ascending frequencies of 100Hz to 16 kHz; default -20dBFS
level)
• Downmix L/R

16 • Before You Begin HDC-8223A(-S) User Guide (v4.0)
The router function provides the following audio outputs:
• 16 channels of embedded audio on SDI processed outputs
• 4 channels of balanced analog audio on four 3-wire balanced analog audio outputs
Output audio crosspoints allow any of these sources to be routed to any of the 16 embedded
output channels or the four analog audio outputs. Each output channel has a mute control and
phase invert control. Peak-responding DashBoard bar graph level meters are also provided.
The processor function provides group enable/disable and de-embedding of the 16-channel
embedded audio SDI input. A bulk delay control allows lip sync correction by offsetting the audio
from video by up to 3000msec.
Audio Down Mix Function
The Audio Down Mixer function provides a downmix to Left only/Right only (Lo/Ro). Any five
embedded channels can be selected for Left (L), Right (R), Center (C), Left Surround (Ls), and Right
Surround (Rs) individual signal to be down-mixed into stereo pair Down Mix Left (DM-L) and Down
Mix Right (DM-R). The resulting stereo pair DM-L and DM-R can in turn be routed to any embedded
audio pair as desired (or de-embedded to an analog audio output). (Figure 2.)

HDC-8223A(-S) User Guide (v4.0) Hardware Overview • 19
Hardware Overview
This chapter provides a general overview of the user controls available on your HDC-8223A.
Control and Monitoring Features
This section describes the card-edge status LEDs and display. These LEDs and the display show
status and error conditions relating to the card itself and remote (network) communications (where
applicable). Because these LEDs are part of the card itself and require no external interface, the
LEDs are particularly useful in the event of communications problems with external devices such as
network remote control devices. Refer to Figure 5 for the location of the LEDs.

LED Color Display and Description
COM Flashing Blue When flashing, this LED indicates that the HDC-8223A is
receiving control message from DashBoard.
REF Blue When lit, this LED indicates that the HDC-8223A is
receiving valid reference.
ERR Red When lit, this LED indicates an internal error.
SDI IN #
Blue Four blue LEDs for each SDI input (A and B) indicate the
input signal raster format being received and locked
onto by the HDC-8223A(-S) (LOCK, 3G, HD, SD).
Continuous cycling of the LEDs indicates the
HDC-8223A(-S) has not locked onto a particular format
(as in the case of no signal input).
Flashing Blue When flashing, this LED indicates that the
HDC-8223A(-S) is receiving a signal which cannot be
processed.
