Parallel Access, Parallel Workflow

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

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

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 Open, CIFS-based Client/Server Architecture

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

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

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

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
