    Session Topics

    What happens when they are only files?

    aka when baseband is no more

    Quality Control in a File-based domain

    Automated Test & Measurement

    How the Network is ImpactedProvisioning and efficiency for content migration

    Content delivery networks - internal & long distance

    Expectations, shortfalls, handling upgrades

    The Demise Of Baseband

    Inevitable reduction of baseband implementations

    Retained for live productionNLE is moving away from exclusive real time ingest

    Baseband costs increase to maintain the status quo

    Non-real time media exchange expands

    Faster or slower depending upon immediacy of content

    Scalable with the network bandwidth/speed

    Ideal for compressed video and file based platforms

    Baseband unnecessary for delivery going forward

    Pre-packaged formats (already in cable & satellite)

    Platform Interchange (direct to air and for transport)

    4/43

    The Value of Working with Files

    Platforms offer unconstrained flexibility

    Content is readily repurposed The transport of content is unbound

    network based vs. point-to-point physical

    Replaces aging analog and digital lineal tapefiles are more durable and extensible

    promotes independence from fixed media formats

    Costs for file only implementations will decrease

    Uses & Expectations

    File-based platforms will

    support the NextGen Digital Media domainaddress ATSCs evolving standards (i.e., A/101

    interactive, A/72 AVC, NRT protocols, ATSC 2.0)

    new mobile applications (A/153 ATSC-M/H)future delivery diversification (VoD, Web)

    Preservation of legacy content and fixed media

    archive content onceclean up analog formats correctly, once and for all

    preserves digital content completely

    File-based Frameworks

    Promote integration through a layered architecture

    Acquisition, storage, manipulation, and deliveryprocesses

    Achieves flexibility by loosely couplingthe infrastructure

    to the applications Force structurefor

    media asset management

    focused work centers, content sharing, collaborationcapabilities that aid in developing or repurposing content

    File-based Frameworks

    Provide consistency in workflow

    broadcast operations will still use several workflowflavors

    applications are extended to work area needs

    from acquisition through content preparationthen to playout and on to archive

    Enabling a Comprehensive

    File-based Environment

    Decisions and Policies must be established:

    Compression types and formats Coding types and bit rates for levels of quality

    Acquisition media (SSM, optical disc, HDD)

    Intra-facility interchange formats

    Archive methods (near-, short- and long-term)

    Disaster recovery mechanism and platform Edit decision making (proxy vs. low-bandwidth)

    Monitoring and quality assurance

    When There Are Only Files

    Many Work Tasks can be Automated

    ingest, quality control, security, backup

    Personnel diversification is improved

    Baseband house formats can be relaxed Platform interchanges gain flexibility

    however, not necessarily simpler or more achievable

    Quality control becomes essential!

    What Operators Wont See or Hear

    Content can be irreparably damaged very early ondangers of image impairment are camouflaged

    with no way to recover from many errors

    and while it may lookgood, it is still no good Errors created in the encoding process

    may be passed through or masked by a good decoder

    may still crash a home STB decoderhard to spot missing I-frames, corrupted syntax, levels of macro-

    blocking, improper motion vectors, etc

    Audio that sounds good, but has:

    out-of-phase, channel swapped or lost due

    channels missing, wrong dial_norm or DRC

    compressed audio but metadata parameters are corrupted

    Audio/Visual Impairments

    Encoding quality errors

    blockiness, improper motion-vector, misorderingmissing or other improper audio metadata

    Timing and segmenting

    mistiming, truncation, extension of heads/tailscommercial insertion triggering errors, splicing errors

    Format errors or missing information

    PAL instead of NTSC, progressive instead of interlace

    line standard or framing incorrect

    Corrective Actions

    Option-1

    decode to baseband, correct with baseband

    processing equipment, re-encode(most aesthetic correction or visual/aural discrepancies

    must be fixed by humans)

    Option-2fix the syntax, (meta)data insertion, or timing

    adjust audio metadata or normalization

    Option-3reject, then re-feed/re-order the content

    abandon and substitute with evergreen material

    Media Dispatch Protocol

    SMPTE EG 2032-4-2007

    For the delivery of files over IP networks

    Three parts to MDPprotocol specification (SMPTE 2032-1)mapping specification (SMPTE 2032-2 for MDP/XML/HTTP)

    profile specification (SMPTE 2032-3 is the basic target pull profile)

    Developed for MAN and WANsuitable for LAN

    MDP is not

    a transfer protocola file wrapper or container format (i.e., MXF, QuickTime, etc)

    uses a content-aware file delivery layer

    Uses highly scalable enterprise-class platforms

    Nodes easily added/removed at new locations

    Unidirectional distribution

    selects most appropriate route available

    multi-cast enabled for satellite delivery

    Media Asset Management

    The Key to Success is in a centralized MAM plan

    essential element in automated file management Requires adopting new workflow principles

    should adhere to open work flow standards

    development of your ownservice oriented architecture (SOA)

    Selecting the right MAM product

    most products are still proprietaryusers often insist upon customizing workflows

    costly, less friendly, often undesired by vendor

  • 8/6/2019 230 File Based World Paulsen BO1 Final

    39/43

    Process and Procedure Setting

    Establish written policies, practices and procedures

    Set acceptability thresholds

    Utilize a reporting check list automate whenever possible

    logging of errors, statistics, all corrective actions taken

    Develop a backup plan with sufficient evergreen content

    Prepare the system failover and failback

    Adopt versioning management (use MXF)

    Know how to find the files

    Catalog with MAM, use check-in and check-out, etc

    Rigidity with flexibility

    Just in Time content delivery may not be practical

  • 8/6/2019 230 File Based World Paulsen BO1 Final

    40/43

    Impacts from System Upgrades

    Upgrades will become a regular part of life

    Make certain you perform regression testing Forward thinking needed for server growth

    play to Air platform, disk expansion, VoD, archive

    Understand that both file and system issues areaffected by

    inter-departmental interchanges or workflow

    platform obsolescence in work zones

    the I need a better mousetrap proliferation

  • 8/6/2019 230 File Based World Paulsen BO1 Final

    41/43

    Shortfalls in Implementation Spotty or incomplete implementation

    Deployed only a portion of the necessary tools

    Insufficient training and exposure prior to launch

    System was customized for todays thinkingsort out and remove unobtainable results

    set aside misrepresentations and vaporware

    Limited acceptance by the staffthe old ways never die, felt threatened, apprehensive

    didnt want to become the guinea pig

    Only a few understand or evangelized the long term,extensible value to the overall organizationinitial ROI didnt meet the accounting expectation

  • 8/6/2019 230 File Based World Paulsen BO1 Final

    42/43

    The Successful Implementation

    Mitigates manual processes

    Reduces time getting products to air

    Minimizes errors improves flexibility

    Creates the perfect paths for

    archivingrepurposing/versioning of content

    disaster recovery/asset protection

    prevention of obsolescence

    Complex at the start worth it in the end
