Scan Do SD - Broadcast Quality SD Scan Convertor
The SCAN-DO/SD is a broadcast-quality, standard-definition scan converter with DVI input and SD-SDI output. The SCAN-DO/SD allows websites, videos, computer graphics, video games or any other computer-generated content, at resolutions up to 1920x1200, to be broadcast in standard-definition format. No additional computer hardware or software is required and all internal processing paths in the SCAN-DO/SD are 10-bit, ensuring a consistently clean, high-quality output.
The SCAN-DO/SD's advanced algorithms allow the input video to be scaled both horizontally and vertically (either independently or locked to maintain a constant aspect ratio) from 25 to 200% and accurately positioned in the output frame. The unit also incorporates extensive video processing features which allow adjustment of the brightness, contrast, saturation, hue and sharpness of the signal. 8 levels of manual flicker reduction are provided together with an automatic mode which selects the optimum level for any given signal.
The unit incorporates SD scan conversion as standard and provides two parallel SDI outputs. A genlock input, compatible with tri-level sync and black-burst, locks the horizontal, vertical and clock phases of the output signal over the entire vertical output period with a resolution of 840 picoseconds. The horizontal, vertical and clock phases can all be advanced or delayed independently.
The SCAN-DO/SD can be controlled via the front-panel push buttons and on-screen display or remotely by connecting the unit to an IP network and using the built-in, user-friendly web interface from a standard web browser. A serial port is also provided for RS232 control. Commonly-used configurations can be stored in the SCAN-DO/HD's internal memory and recalled using either of the remote control ports.
The SCAN-DO/SD incorporates a colour bar generator, providing a convenient test signal source. For additional information please see the Scan-Do/SD Manual
