The Osprey-�1100 is a cost-effective video/audio codec designed to be the cornerstone of a Sun Solaris video communications system. Implemented as a half-slot SBus card, the Osprey 1100 offers a variety of industry standard compression formats and can operate in Sun SPARC/SBus-based platforms. The Osprey-1100 enables Sun workstations for a variety of advanced video multitask operations such as Intranet conferencing, Internet video streaming, security / surveillance, and other video communications. The Osprey-1100 is compatible with the SunVideoPlus Card and supports SunForum. The Osprey-1100 is compatible with Sun SBus-based SPARC workstations running Solaris 2.5.1, or 2.6. Video I/O, Audio I/O, and support for standard compression formats creates a perfect multimedia platform to complement the power of the Sun workstations. Developers can quickly create interoperable video communication systems using the standard XIL interface or the Osprey-1100's SunVideo binary compatibility mode.

Architecture
Audio compression can be performed by either the on-board DSP or by the video processor (depending on the type of compression required). Compressed streams pass through the Bus Interface subsystem and onto the host system's bus. A host application can then manipulate the data, forward the data to an ISDN card, send the data out to a LAN through a network card, or store the data to a file. The decompression operation simply reverses the compression process. Video decompressed by the card may either be (a) directed to the composite video out port for external display or (b) moved to the host via DMA for display on the host machine's monitor. See the Osprey-1000 FAQ for information about video out. The PCI (Osprey-1500) and SBus (Osprey-1100) versions of the card use the same video and audio processing logic--only the bus interface logic is different. Configurable/OEM Solutions
