What QC processes are in place to ensure digitisation (including the metadata) from tape has been successful?
Benoit Février, EVS
media-aware storage solution. The key is that the system can accommodate requirements specific to handling media. Partial transfers, for example, are a valuable and frequently used capability of media-aware systems that save time, space, and money. Likewise, the ability to find whole media assets or subsections is a valuable capability. Systems that are aware of mastering formats are also important as they allow for efficient storage of assets that may be delivered in many versions. Taylor: There is no simple
answer to this, and we certainly should not be looking at these as mutually exclusive. What is important is that you start by evaluating the needs of each media business. I believe that the media industry has to embrace IT solutions. I also believe that the media industry needs to stop re-inventing technology when a perfectly capable solution is available. Walsh: A combination of
off the shelf IT hardware with specialist software developed for the particular needs of a video workflow is in our view the most cost effective and reliable solution.
Should archiving and storage be a standalone function — or a part of a wider MAM solution?
Dymond: The business function of archiving material can provide users with availability to content along with wide ranging metadata indexing and search capabilities. Advanced users can really benefit from concise
search tools based around deep asset and time based index points for locating material down to a shot/frame level. Fanichet:We are seeing both configurations – it really depends on the DNA of the companies we are dealing with, as well as the volume of the digital content assets. However, companies handling large volumes of digital assets tend to rely on leading MAM packages that Quantum supports as part of StorNext. Gallen: Without a MAM in the centre of such a solution the true value of content is unlikely to be realised. The MAM aggregates information — metadata — from many sources and attaches it to content items making them more easily discovered using a search engine. Hoggarth: Even within a single company there are likely to be classes of users with very different requirements. The choice of a separate archive with a DAM or archive manager, or a MAM with integrated storage management, can only be based on the needs of the business. Both have their places. Pearce: Can be both. We advise
an incremental approach to storage and workflows. Start with stand alone options and then move to a wider more integrated MAM approach as and when the business requires. An important consideration is to choose platforms that can be integrated at a later date. Choosing archive platforms with APIs is advisable. Rehrer: Storage and archiving
must be part of a wider MAM solution. While storage can provide the necessary performance and sometimes tools such as partial-restore, the powerful search capabilities, and more robust application interface functionality truly are the domain of the MAM system. What’s more, these capabilities are largely what make a solution media- aware. Thus, a broadcaster should look at vendors that offer ingest, playout, storage and MAM solutions.
Weigner: No MAM, no hope. Février: There are different approaches to this. We see customers who want to check their baseband SDI video signal before digitisation, especially when the tapes are very old. Others want to check the file after it has been ingested. The use of eyes and ears seems to remain a required step in the file QC process, often complemented by an automatic file QC before moving to long- term storage. Also checking the integrity of content with checksum generation and preservation has become crucial.

a workflow that tracks the progress of a clip through different QC stages. For instance, once a clip has been captured, e- mail can be automatically generated to notify QC staff that it is in the queue. Then, once QC marks a clip approved, that can trigger other e-mails as well as transcode actions to create different deliverables. These triggers give you the ability to track very powerful and complex batch workflows. Hoggarth: The essence of a good solution is not only to detect and quantify every possible defect, but to present the mass of available data in a way that can be interpreted by users to get the job done. From the perspective of an archive storage specialist, the QC process is typically a separate upstream or downstream process, but there can be advantages to performing QC process within the archive storage platform itself.
“While storage can provide the necessary performance and sometimes tools such as partial-restore, the powerful search capabilities, and more robust application interface functionality truly are the domain of the MAM system”
Gallen: For digitising
workflows we support automated QC from Baton, Cerify and others as well as having the capability to do a manual check on content quality. Another benefit of a having a workflow manager is that existing metadata is displayed for operators to check UIDs, names and other metadata as part of the ingest or import tasks.
Herzog: EditShare sells SDI-based ingest products that can capture from tape sources. At every step (during capture, editing, archiving, etc), there are opportunities to add required metadata to the captured clip. And with EditShare Flow’s new Automation application, you can create triggers that cause certain actions to happen based on the status of a clip, creating

Has the increase in multi-screen activities had any impact on archive and storage demands?
EditShare enterprise: The Enterprise Multimedia Centre is an EditShare installation for storage
Dymond: Many broadcasters and service providers are still struggling with manual processes and heavily resource intensive operations surrounding non-linear content distribution. This can be as simple as creation of video assets with specific transcode profiles, but as complex as customised versioning with metadata packaging. The number of manual processes means that there are often currently huge numbers of manual touches on content which increase the user serving bandwidth requirements for storage.
