StreamLabs WIND SDI 2 with ALPHA Pro Software
PCI-card for overlay and output of computer graphics

Stream Wind SDI II is a PCI-card for overlay and output of computer graphics. It can be used as a basis for creation of on-air graphic design systems (CG-systems) and broadcasting video servers.

- Works with 8 and 10-bit component serial SDI signal, in accordance with CCIR656 and SMPTE259m recommendations. SDI embedded sound support. Automatic activation of video signal relay bypass mode upon computer power loss;

- Synchronization from input SDI signal or analog Black burst (Composite) signal. When external synchronization is lacking internal synchronizing generator is applied;

- Digital key signal (alpha-channel) output for use with external mixer that has a DSK (Down Stream Key) input. Key signal delay relative to output graphics has a software controlled wide adjustments range;

- 8-channels (4 stereo pairs) SDI Embedded audio input/output;

- When SDI signal passes through the card all the service information is saved, sound can be either kept or changed depending on the situation;

- Error control in incoming SDI signals with check total count according to EDH method. EDH packets on the output are formed anew in accordance with


Character Generation program Alpha Pro 2.0, which operates in Windows XP / Vista / 7 environment, is designed for titling, creating interactive programs, telephone voting on-air, displaying blocks of commercials, and design of live television programs, such as: news, weather forecasts, sports reports, talk shows, etc. Alpha Pro 2.0 combines many years of engineering experience and current professional video production requirements.

Concerning the possibilities of artistic design, the limit is only the artist's imagination; any fonts, three-dimensional shadows, semitransparent masks, textures, complex multilayer compositions, animation, etc. can be employed.

Program features:

- TV-program titling while editing or on the air, manually or in automatic mode;
- Text and graphic information display in form of crawl and roll;
- TV-channel / program static or dynamic logo display;
- Automated time or temperature display;
- Telephone voting results broadcast;
- Any kind of analog or digital clocks generation and display;
- Informational and graphic design of interactive talk-shows, news and sports reports;
- Animations and logos playback;
- Cyclic playback of scripts;
- Multi-layered graphic windows for incoming information display.

High quality and ease of Character Generation:

- Using all available Windows TrueType fonts;
- Symbols and tickers design with complex 3D-shades, borders, outlines and borders;
- Using text processors and graphic editing programs principles;
- Fonts with random direction gradients, textures including images in JPEG, BMP and TGA 32-bit formats;
- Anti-aliasing broadcasting rasterization quality;
- Line interlacing flicker filter;
- Placing logos as symbols in crawls;
- Using 16.7 million colours and 256 transparency levels to fill any page element.

Usability and efficiency:

- Edit and hold in readiness several scripts simultaneously;
- Classical Windows program interface and WISIWYG mode;
- Instant title output by using prepared scripts (templates).

Wide range of linear effects:

Script consists of an unlimited number of pages; every page has a video effect assigned to it.

Alpha Pro 2.0 uses the following effects:

- Vertical Roll - text that runs vertically from bottom to top;
- Horizontal Crawl - "endless" page of random height and length that runs horizontally from left to right;
- Reveal Up / Reveal Left - horizontal and vertical slide-ins;
- Animated logos and clips playback as an individual effect, or as a part of titles block;
- Fade In / Fade Out / Cross Fade - smooth transition effects;
- Zoom - scaling effect;
- Near 300 kinds of Wipes with transition softness settings.

All effects can be displayed on full screen or in any specified rectangular area. All effects have speed, duration, delay, timing or external events control settings.
