  1. An Open, CIFS-based, Client/Server Architecture for the Media Enterprise Presented by:John L. PittasVP Broadcast Products EngineeringSeaChange International

  2. Parallel Access, Parallel Workflow

  3. Ingest-in-Place, Edit-in-Place, Play-in-Place • Key elements of tapeless workflow • Centralized Fault-Resilient Shared Storage • Reduces/eliminates multiple storage platforms • Reduces cost and complexity • Reduces/eliminates content movement • Accelerates user access and time-to-air • Reduces/eliminates asset management layer • Reduces cost and complexity • Open File Access Protocols • Eliminates proprietary protocols • Accelerates system integration and stability • Reduces cost and complexity • Assures interoperability across multiple Operating Systems • Applications use native file system calls

  4. Ingest-in-Place, Edit-in-Place, Play-in-Place • Key elements of tapeless workflow (cont’d) • Common Data Structures • Eliminates/reduces proprietary essence and multiplexes • Accelerates system integration and stability • Reduces cost and complexity • Promotes interoperability across multiple applications • Eliminates/reduces data conversion overhead • Reduces cost and complexity

  5. Open, CIFS-based Client/Server Architecture

  6. Open, CIFS-based Client/Server Architecture • Key elements of the architecture • Common Internet File System (CIFS) – Ubiquitous • Server Message Block (SMB) protocols supported by Windows, Apple, Unix, Linux • Storage appears as remotely-mounted drive • Support for small files, hierarchical directories, advanced file security and authentification • IP Networking – Ubiquitous and inexpensive • Jumbo frames and QOS for video applications • 1Gb/s for streaming tape drives, compressed SD/HD, uncompressed SD • Future migration to 10Gb/s for uncompressed HD and D-Cinema • x86 – 32/64bit I/O and Processing Subsystems – Ubiquitous and inexpensive • Intel/AMD competition advances CPU price/performance • Windows/Linux competition advances OS price/performance • Multiple development teams advance applications price/performance

  7. IP-attached I/O and Processing Subsystems • I/O subsystems bridge synchronous A/V I/Os to the asynchronous IP network of central storage • Uncompressed SD or HD • Compressed SD or HD using SW-based codecs • MPEG/IMX • DV25/50/100 • Requires high-end x86 platform • Specialized SDI/HD-SDI I/O HW • Asynchronous subsystems provide content processing/transfer between third-party systems and central storage • Require no specialized I/O HW

  8. IP-attached I/O and Codec Subsystem RS-422 Command Interpreter File System Re-director IP Stack Real-time Record, Play and Codec Engine IP Internal RAID Hardware Abstraction Layer SDI/HD-SDI A/V I/O Card GENLOCK

  9. Metadata Generators • Creates metadata for content created on or imported into central storage by third-party applications using industry-wide standard codecs such as DV25/50/100 • NLEs or • File imports via CIFS or FTP • Requires inexpensive x86 platform • Content does not “pass through” the Generator • Continually scans the storage for content lacking associated metadata • Automatically creates the metadata

  10. Essence Gateways • Gateway solution for importing/exporting non-standard MPEG content between third-party systems and central storage • Tape and disk-based systems • File transfers via CIFS or FTP • Requires high-end x86 platform • Content “passes-through” the Gateway • Processes/massages audio/video essence and multiplex • Creates index and metadata • Supports “play during transfer” • Performs multiple simultaneous real-time transfers or • Faster than real-time transfer depending on available device bandwidth
