     All Sessions   |   Room 1

  • Module 1: Introduction to file-based technologies
    The essential elements of AV/IT systems and file-based technology are reviewed. This includes the eight converging forces, three fundamental modes of transfer, client types. Hybrid AV/IT systems are compared to traditional AV systems showing the pros/cons of each method across 17 different metrics. Key methods are developed showing how to achieve video frame-accurate I/O with IT networking.
  • Module 2: Storage Systems for AV workflows
    This material covers storage and the systems technology that underpins AV/IT systems. Consideration of storage virtualization, clustered file systems, hierarchical storage, storage connectivity, ATA vs. SAS drives, and optimizing storage for real-time AV I/O. SAN, iSCSI and NAS are compared. Fibre Channel and Ethernet are contrasted as SAN conduits. Storage QoS metrics, data transfer acceleration and caching methods are applied to AV systems.
  • Module 3: Software technology for AV
    Software systems organization is explored including system classifications and comparisons. Distributed models are explained, including client/server, peer-peer, Web services models (W3C and REST) and middleware’s role. The service-oriented architecture (SOA) is explained with application to AV systems. Media services are explored with review of industry progress and the FIMS Initiative (Framework for Interoperable Media Services). Cloud basics are reviewed. Data center virtualization scenarios and their usage are explored for AV workflows.
  • Module 4: Reliability and scalability methods
    File-based technology depends on reliable IT platforms. This module develops the basics of high availability (HA) systems design, including RAID storage-array classifications and their operation for real-time AV. Trade-offs between MTBF and MTTR are examined in the context of high availability for AV systems. One- and two-dimensional RAID error correction means are compared. Alternate techniques for array reliability are described. Advantages and cautions of AV data striping are outlined. Fifteen strategies for creating HA designs are presented using standard IT methods.
  • Module 5: Networking basics for AV
    Basic network stacks are examined. Understanding layer 2 vs. layer 3 and the advantages of each layer. IPv4 LAN segmentation/VLANs are explored with real-world examples. Transition strategies to IPV6 are reviewed. TCP and UDP is explained and compared for AV file and stream transport across short and long distances. Techniques are outlined for speeding up file transfers across long distance and for cloud storage. The new IEEE Data Center Ethernet standard is applied to media systems. Switched and nonswitched WAN techniques are classified and segmented for AV use. Seven layers of QoS for transport are explained. MPLS is reviewed for interfacility streaming and file transfer.
  • Module 6: Systems integration concepts
    This section ties other module concepts together to create full-featured hybrid AV/IT systems. The three planes (data, control and management) are explained and applied to AV workflow design. Eight AV timing domains are explained along with three fundamental time-based control methods. Interoperability fundamentals are outlined. Other coverage includes file wrapper formats, metadata standards, the physical and logical layout of MXF and relevant specs from industry bodies. MAM essentials are explained. The “butterfly” problem is examined in relation to multiformat, multiplatform, multi-endpoint program distribution. Workflow patterns are reviewed.
  • Module 7: Security for networked AV systems
    Enterprise defense fundamentals are reviewed, including building blocks for the secure media facility. Included are understanding life-cycle threats, five tactics for secure isolation, bridging business and mission-critical media operational domains. Data encryption basics are explained using simple examples. Public and private key methods are compared. Digital signatures are explained and applied to AV materials. Program watermarking and fingerprinting methods are reviewed with applications.
  • Module 8: The fundamentals of cloud computing
    Cloud computing will change the landscape of the media facility. Coverage includes review of fundamentals and business benefits, the comparison of three cloud types, and examples of elasticity. Public and private clouds are contrasted. The “pay by the sip” cost models are examined. Server virtualization is shown to be a key enabling technology for secure, efficient and on-demand use of cloud computing resources. Compute benchmarks are provided. Examples of cloud-based, media-related applications are reviewed. The future is contemplated.
