Sirius Video™ is a video option for IRIS® workstations equipped with RealityEngine™, RealityEngine2™, VTX™, or InfiniteReality™ graphics. It fully integrates broadcast-quality video with Silicon Graphics® supercomputer graphics capabilities. Sirius Video can also be installed in CHALLENGE® servers and POWER Series™ server configurations, making its broadcast-quality video a network resource.
The option utilizes one VME slot; input and output connectors are on a breakout box. Multiple Sirius Video boards can be operated in serial or parallel for multilayered video effects or video server capability.

Sirius Video is designed for the sophisticated video user in a professional or research environment. It utilizes calls in the Silicon Graphics Digital Media library, such as the Video Library, as well as calls that are native to Sirius Video only.
Sirius Video supports real-time input and output of video in the full range of broadcast video formats. The user can view high-resolution images from the workstation in low resolution, or capture low-resolution images in real time and view them on the high-resolution workstation monitor.
Sirius Video enables the user to blend graphics and frames from video in many ways, including alpha blending and chroma and luma keying. The user can also generate pixel fades and wipes in real time from external alpha. The user can blend low-resolution input with workstation-derived images for low-resolution output.
For controlling videotape recorders, Sirius Video includes an on-board V-LAN™ transmitter to send high-level VTR commands over a coaxial network.
The Sirius Video option includes the Sirius Video Programming and Configuration Guide (007-2238-003). The following guides contain instructions for exchanging circuit boards and other crucial information:
