Sirius Video™ is a video option that provides IRISŪ and POWER Onyx™ workstations equipped with RealityEngine™, RealityEngine2™, or VTX™ graphics with broadcast-quality video. Sirius Video can also be installed in CHALLENGE™, POWER Series™, and POWER CHALLENGE™ server configurations, making its broadcast-quality video a network resource.
 | Note: See the release notes for compatible versions of IRIX on various platforms. |
For controlling videotape recorders, Sirius Video includes an on-board V-LAN™ transmitter. The transmitter sends high-level commands to videotape recorders that are equipped with receivers purchased separately from third parties.
The option consists of a board that fits into a VME slot in the chassis, a paddleboard, a breakout box, cables, software, and documentation.
| Note: Sirius Video uses the Video Library™ (VL). VL device-independent calls and controls are explained in the Digital Media Programming Guide. The Sirius Video Programming and Configuration Guide is written on the presumption that you are familiar with the VL information in the Digital Media Programming Guide. |
