Introduction
Video Processor Description
BBG1003UDXADDA-OM (V1.2)
The BBG-1003-UDX-ADDA features a up/down/cross-convert scaler, frame
sync, and user-adjustable aspect ratio control and zoom control. The
BBG-1003-UDX-ADDA video subsystem also provides the functions
described below.
Input Video Select
A GUI-based control allows the device to select from up to four 3G/HD/
SD-SDI inputs, and a SD CVBS or HD/SD YPbPr component analog video
input. For analog inputs, waveform-based ancillary data is preserved for
extraction and usage later in the processing chain. Analog video processing
uses 10-bit processing with 5-line adaptive comb filtered SD Y/C separation.
A raster size/rate user input select filter tool can set the device to accept only
specified raster size/rates, while rejecting other inputs that do not conform.
The input can be selected using user manual control, set to failover to an
alternate input upon loss of the target input, and can be externally selected via
a GPIO interface. All SDI input ports feature RP168 clean switching
performed on the specified VBI switch line when a user-selected input change
is effected.
Timecode Processor
(See Figure 1-2.) This function provides for extraction of timecode data from
input video source, and in turn allow individual timecode strings to be
embedded in the output video. The function can monitor any of the video
inputs for supported timecode formats such as ATC_LTC or ATC_VITC for
down-conversions to HD, and ATC_VITC or VITC waveform (with
selectable odd/even field line number control) for SD SDI or CVBS inputs.
Waveform VITC timecode can also be extracted from a reference input and
used as the output timecode value. If the preferred format is detected, the
preferred format is used; if the preferred format is not detected, other formats
(where available) can be used as desired. An internally-generated free-run
timecode can be also be embedded on output video if desired.
The function also provides conversion between various timecode formats and
provides independent insertion and line number controls for each SDI
timecode output format.
When licensed with option
receive, send and translate between audio/RS-485 LTC timecode formats and
the VBI formats described above.
