Video Processing Description

1-4
Figure 1-1 shows a functional block diagram of the BBG-1070-QS. The
BBG-1070-QS includes input processing functions to accommodate SDI and
CVBS analog inputs, a validity check function to provide indication of input
defects, timecode and audio data handling and routing control, multi-split
ARC/scaling functions, a timing alignment function to synchronize the inputs
to house reference, up to 5:1 Picture-in-Picture (PiP) video combining, and
burn-in attributes and control of borders, UMD display text, audio meters, and
other accessory displays. The output is available as a 3G/HD/SD-SDI output
or HDMI/DVI. The output raster format and aspect ratio is user-configurable.
The BBG-1070-QS provides the following inputs and outputs:
Inputs:
• SDI/CVBS IN A thru SDI/CVBS IN E
(auto-detecting 3G/HD/SD-SDI or CVBS analog video)
Outputs:
• 3G/HD/SD-SDI OUT
• HDMI/DVI OUT
embedding (suitable for direct connection to monitor panels)
The BBG-1070-QS features input select and validity check functions, timing
alignment, and PiP ARC/scaling functions as described below.
Input Video Select Function
Auto-detect per PiP inputs independently set each of the device video inputs
as 3G/HD/SD-SDI or CVBS SD analog video. Either mode preserves
waveform and packet-based ancillary data for extraction and usage later in the
processing chain. A CVBS input is automatically detected by the device
input, with the CVBS ADC converter automatically engaged in these cases.
Timecode Processor
This function provides for extraction of timecode data from any of the five
per-PiP input video sources, and in turn allows timecode strings to be burned
into the respective PiP images. The function can monitor any of the device
video inputs for supported timecode formats such as HD ATC_LTC or
ATC_VITC, and ATC_VITC or VITC waveform for SD SDI or CVBS inputs.
ARC Processor
This function provides separate ARC controls for each PiP input. The
separate controls can re-aspect SD to match the aspecting used for HD inputs,
and vice versa. Custom aspecting is also available for both HD and SD
formats.
