Harmony Series of MPEG-2 Decoder Circuit Boards

Harmony 2ES and Harmony 4ES

The Harmony series of  professional MPEG-2 decoder cards  from Visual Circuits feature standard component, RGB (sync on green), s-video or composite output and Dolby Digital audio output.  Harmony cards are ideal for demanding, high-end multimedia applications.

A high-quality, 256-color on-screen display feature allows for graphics or text information to be overlaid on the video with varying levels of transparency. Create eye-catching kiosks, entertainment, visual merchandising and video-on-demand applications by integrating high-quality graphics over video.

The Harmony 2ES and 4ES are identical in specifications and features,  the only difference is the number of channels on board. Harmony 2ES and 4ES cards are multi-card enabled, and are compatible with each other within the same computer system, so they can be mix-and-matched for exactly the number of channels required.  Cross-channel synchronization can be achieved across multiple cards, allowing for elaborate multi-channel synchronized presentations.  

A complete C or Visual Basic programming library with sample source code and function calls is provided. This Software Development Kit provides the necessary tools to develop advanced digital video playback applications under Windows XP / 2000 / NT 4.0.

The Harmony Series cards by Visual Circuits enables companies to use digital media technology to improve their business, personalize their messages and communicate more effectively with customers and employees.
