  3. SGI Video Servers • Overview • Based on SGI Origin Servers • SGI Hardware, Software, and Services to produce a broadcast quality video server

  4. SGI Video Servers • Key Features • Open System Architecture • Format Independent • Treats Media Content as Both Media and Data Simultaneously • High speed data networks • File transfer and play/record simultaneously

  5. Origin Servers • Hardware Platform • ccNUMA architecture • Extremely high throughput (multiple uncompressed HD) • Scalable • No limits like bus-based architectures • Origin200 GIGAchannel • High volume product • Highly reliable • Redundant power and cooling • Mirrored system disks

  6. Origin Servers • Storage Options • Internal and External UltraSCSI storage • RAID-0 or RAID-1 • External Fibre Channel storage • Ciprico FibreSTORE and Ciprico 7000 • RAID-0, RAID-1, or RAID-3

  7. Origin Servers • Software Platform - IRIX 6.5 • Variant of SVR4 • REACT Real-time Scheduling • UST/MSC Synchronization • XFS Real-Time Filesystems and Guaranteed Rate I/O • XLV Logical Volumes • dmBuffers

  8. SGI Video Server SoftwareKey Features • Video Server Toolkit • Modular, Extensible Architecture • Frame Accurate • Automation control protocols • Format Independent • MPEG-2 to Film • I/O Independent • Video, bit stream, network, etc.

  9. VST Architecture Block Diagram Archive Control VTR Core Storage Format Media I/O Device

  10. VST ArchitectureFormat Modules • Handle for accessing specific storage formats • Translation from Media Units to Data Access Untis • Timecode to byte offset

  11. VST ArchitectureFormat Modules Implementations • Variable Frame Size (vframe) • RICE, M-JPEG, Uncompressed • Bitstream (stream) • MPEG-2 Transport Stream and Program Stream • DVCPRO (dif) • DVCPRO • Virtual Clip (vclip) • EDLs

  12. VST ArchitectureFormat Modules Virtual Clips • Built from Sequences of Other Clips • List of clips with edit points • Shares media content with original clip • Clip segments must be of the same format • Treated like All Other Formats • Handles Deletion of Original Clip

  13. VST ArchitectureMedia Modules • Interface to Media I/O Devices • Manage transfers to and from I/O Device • Define Port to I/O Device Mapping

  14. VST ArchitectureMedia Modules • Implementations • DIVO, DIVO-DVC • Uncompressed, RICE, DVCPRO, SDTI • DVB-ASI • MPEG-2 Transport Stream (up to 45 Mb/s) • Vela 4-port MPEG-2 decoder • MPEG-2 Transport and Program Streams • O2 (For Development Purposes) • M-JPEG
