1-2. BROAD SCAN HD GENERAL INFORMATION
Broad Scan HD by Analog Way is a Broadcast and Professional Computer to Video and High Definition TV Scan
Converter. Fitted with Digital DVI and Analog RGB input, it converts Workstation, PC or Mac graphic images up to
1600x1200 @ 60Hz (1920x1200 RB) into Video or HDTV. Each computer input has its own monitor loopthrough out
for the connection of a control display. Output signal can be both analog and digital thus Broad Scan HD can provide a
full Digital signal processing path from the input to the output.
Broad Scan HD features a powerful broadcast Genlock. Two versions of the Broad Scan HD offer either a Digital
HD/SD-SDI Genlock (Model BHD930-DG) or an Analog HD Black or Black Burst Genlock (Model BHD930-AG).
Genlock input is fitted with a loop through output allowing chaining devices. The user can adjust phase and subcarrier
delay according to the specific installation requirements. HD output formats can also be genlocked with a SDTV Black
Burst signal. All Genlock timings meet broadcast ITU/SMPTE standards.
Broad Scan HD supports many Output formats as listed below:
HDTV
• 720p @ 60, 59.94 & 50 Hz (SMPTE 296M),
• 1080i @ 60, 59.94 & 50 Hz (SMPTE 274M),
• 1035i @ 60 Hz & 59.94 Hz (SMPTE 260M),
• 1080sF @ 30, 29.97 & 25 Hz (RP2H/SMPTE 274M),
• 1080p @ 30, 29.97, 25, 24, 23.98 Hz (RP2H/SMPTE 274M).
SDTV
• NTSC – 525i @ 60 & 59.94 Hz – 15.735 kHz - ITU / RS170-A
• PAL– 625i @ 50 Hz – 15.625 kHz – CCIR
Broad Scan HD outputs different signals at the same time in one selected output format:
• In HDTV: Two HD-SDI and one HD-YUV 3 level sync signals are available simultaneously.
• In SDTV NTSC/PAL: Two SDI, one YUV or RGB, one S.Video and one Composite Video signals are available
simultaneously.
Broad Scan HD also outputs a Luma Key signal in both Digital and Analog format. Luma key is at the same format as
the output and is perfectly synchronized. In addition, a Frame Lock output allows synchronizing external device frame
rate such as some graphic cards.
Broad Scan HD features real time conversion with high performance Image Processing. User adjustments offer an Anti-
Flicker filter to significantly reduce flickering of the interlaced HD/SD-TV outputs, as well as 2D Sharpness, RGB level
and Black level. It converts single wire computer type signal into black and white video image just by setting a menu.
The state of the art high speed hardware FPGA allows aspect ratio control and a wide range linear or nonlinear zoom up
to 1000%. In addition, a new “zoom finder” is provided to preview the actual part of the picture to be zoomed (H, V and
H&V simultaneously). Broad Scan HD also offers a Frame Memory to store a full screen image that can be displayed at
any time, as well as 1 animated or 4 still logos.
Broad Scan HD allows embedding analog audio Stereo signal into the HD/SD-SDI signal (fs = 48 kHz @ 20/24 bits),
with matched A/V delay.
Broad Scan HD is designed to be User Friendly thanks to many direct access functions such as Freeze, Frame,
Under/Over scan, Aspect Ratio, Zoom position and size. It also provides easy to use and efficient menus on a clear
bright blue LCD screen. LCD continuously displays Input and Output status during operations.
Broad Scan HD includes Computer input format memory: Up to 16 user presets are stored in the machine
corresponding to 16 different input formats. The exact adjustments of the frequently used formats are instantly recalled,
which makes the Broad Scan HD ideal and very useful for multi-computer applications or rental.
