BROAD SCAN (HD/SDI)

1-3. BROAD SCAN SDI INFORMATION

Broad Scan SDI by Analog Way is a Broadcast and Professional Computer to Video Scan Converter. Fitted with Digital DVI and Analog RGB input, it converts Workstation, PC or Mac graphic images up to1600x1200 @ 60Hz (1920x1200 RB) into NTSC or PAL Video.

Each Computer input has its own monitor loopthrough output for the connection of a control display. Output signal can be both Analog and Digital, thus Broad Scan SDI can provide a full Digital signal processing path from the input to the output.

Broad Scan SDI features a powerful Broadcast Genlock. Two versions of the Broad Scan SDI offer either a Digital SDI Genlock (ModelBSD830-DG) or an Analog Black Burst Genlock(Model BSD830-AG). Genlock input is fitted with a loop through output allowing to daisy chain devices. The user can adjust phase and subcarrier delay according to specific installation requirements. All Genlock timings meet broadcast ITU/SMPTE standards.

Broad Scan SDI output formats are:

•NTSC – 525i @ 60 & 59.94 Hz – 15.735 kHz - ITU / RS170-A,

•PAL– 625i @ 50 Hz – 15.625 kHz – CCIR.

Broad Scan SDI outputs different signals at the same time in one selected output format NTSC or PAL: Two 10 Bits SDI, one YUV or RGB, one S.Video and one Composite Video signals are available simultaneously.

Broad Scan SDI also outputs Luma Key signal in both Digital and Analog signals. The Luma key signal comes in the same format as the output and perfectly timed. In addition, a Frame Lock output allows synchronizing an external device frame rate such as a graphic card.

Broad Scan SDI features real time conversion with high performance Image Processing. User adjustments offer an Anti- Flicker filter to significantly reduce flickering of the interlaced TV out-puts, 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 linear or non linear zoom capability up to 1000%. In addition, a new highlighted “zoom finder” is provided to preview the actual part of the picture to be zoomed (H, V and H&V simultaneously). Broad Scan SDI 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 SDI allows embedding Analog Audio Stereo input signal into the SDI output signal (fs=48 kHz @ 20/24 bits), with matched A/V delay, adjustable level, balance and mute.

Broad Scan SDI 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 has easy to use and efficient menus on a clear bright blue LCD screen. LCD continuously displays Input and Output status during operation.

Broad Scan SDI includes Computer input format memory: Up to 16 user presets are stored in the device corresponding to 16 different input for-mats. The exact adjustments of the frequently used formats are instantly recalled which makes the Broad Scan SDI ideal and very useful for multi-computer applications or rental.
