About the Miranda DVI-Ramp2 Graphic to HD&SD Video Interface
The Miranda DVI-Ramp2 is a professional video interface device designed to convert high-resolution computer graphics signals into broadcast-compatible high-definition and standard-definition video formats. This unit accepts a DVI input from a computer or graphics workstation and provides multiple simultaneous outputs, including HD-SDI, SD-SDI, and analog component video, allowing seamless integration of computer content into live production, post-production, and distribution environments. Its primary function is to act as a high-quality scan converter, ensuring that computer-generated graphics, text overlays, and user interfaces are faithfully translated into the interlaced or progressive scan video standards used by broadcast switchers, routers, and recording systems. The device employs advanced scaling and de-interlacing algorithms to maintain image integrity, sharpness, and color accuracy throughout the conversion process.
A critical feature of the DVI-Ramp2 is its ability to handle a wide range of input resolutions and timings, automatically detecting the source signal and locking onto it reliably. It provides extensive control over the output image, allowing operators to adjust parameters such as position, size, phase, and filtering to optimize the result for the target display or broadcast chain. The unit often includes genlock capability, enabling its output to be synchronized with an external house reference signal (such as black burst or tri-level sync), which is essential for clean switching between multiple video sources in a live production environment. This makes it a valuable tool in broadcast control rooms, mobile production trucks, and OB vans where computer content must be integrated with camera feeds.
Housed in a compact, half-rack or full rack-mountable metal chassis, the DVI-Ramp2 is built for continuous operation in professional facilities. It typically features both local control via front-panel buttons and an on-screen display, as well as remote control via serial (RS-232/422) or Ethernet interfaces for integration into automated systems. By providing a robust, high-quality bridge between the computer graphics and professional video domains, the Miranda DVI-Ramp2 facilitates the reliable use of presentation software, character generators, and other PC-based content in critical broadcast and production workflows.
