One workflow, multiple platforms - today s 4K media t management

To ensure the success of future end-to-end 4K workflows, a MAM system is key for any broadcaster.

Vizrt will demonstrate an advanced 4K video workflow at NAB 2015, booth SL2417.

Broadcasters and professional video production companies working in live entertainment, sports and news continue to be tasked with capturing, preparing and distributing content in the fastest and most efficient way. The implementation of an effective media asset management (MAM) platform that benefits the entire chain of production has become critical.

Today's best MAM systems are capable of simplifying the production environment and adapt workflows, while providing the related tools needed to optimize the production of the many versions and variants an asset needs to be delivered.

Production teams need a comprehensive platform, with a common user interface, that manages all content in a central repository while producing video files for many platforms. Access to tools and assets must be regulated - not only for security, but also for usability. Permissions for accessing and editing projects need to be customizable to specific team members or open for everyone to collaborate.

Cloud based storageAnother key to efficient media production is easy access to the right assets at the right time. For this to happen, numerous production staffers must be able to access a reliable central repository where assets are stored, searched for and retrieved along with a cutting-edge file management system. Users must be able to use and access this content simultaneously. In years' past this central storage was located on site within a facility. Today, that same capability can be expanded to the cloud, enabling professionals located anywhere in the world to access files and collaborate in real time. Indeed, cloud-based storage will be key to keeping up with the ever-increasing demand for more content.

Integrated and streamlined tools allow asset production and delivery to any platform in one workflow, enabling content packaging and delivery that is dramatically more efficient than traditional workflows. Extensive live entertainment experience - from high-profile concerts to major sporting events like Olympic Games and FIFA World Cup - as well as live newscasts for the likes of BBC, CNN and Fox News, brings a unique understanding of the requirements for these fast-paced, no-compromise productions. Field-tested technology, such as the Viz One enterprise-level MAM system, helps customers quickly find desired content stored on servers and sends it to the right desktop for further processing (e.g., editing in an NLE, or graphics production with tools such as the Viz Artist application). The underlying infrastructure is able to manage all types of media during production - including for ingest, cataloging, archiving and editing.

Live conform and multiplatform distributionBy taking advantage of sophisticated IP-based infrastructures, systems like Viz One allow broadcasters to make edits to video and graphics from within their native newsroom system until the last moment before content is sent live to air. The edit decision list (EDL) and graphic information are stored as metadata, with the video and graphics playlist then sent to the control room, with the final piece played back in real-time on-air - automatically sized and distributed online and to mobile devices. The workflow saves tremendous space by storing only original files rather than clogging servers with edited content, and saves time by performing the conforming process live with automatic multiplatform distribution.

Using metadata to optimize search

Enriching assets with metadata such as titles, descriptions, categories, markers, keywords, annotations, and scene descriptions make it easier for users to locate and retrieve the right media. Automated file movements, housekeeping, but also graphics can and should be automated to utilize metadata.

To be most beneficial, the metadata must only contain the relevant information that will streamline your production. Within the Viz One system all production tools can add metadata - but there is one dedicated application for just adding metadata - the Logger. The Logger helps organize and add descriptive time-based information to assets in the central repository. Loggers, catalogers, archivists and journalists can add a wide number of different types of information to a file, such as archive metadata, compliance notes, edit notes, QC notes, scripts, highlights and subclipping. Other users such as producers, editors and journalists can find material based on this data instantly. By leveraging the user-configurable, metadata-modeling tool inside Viz One, any type of event can be supported. And once a file is uploaded - sometimes even before a file is fully uploaded - into the server, all metadata is instantly searchable by the entire team. New metadata and changes made are instantly updated in all applications managed by the system.

Building MAM for a 4K futureTo ensure the success of future end-to-end 4K workflows, a MAM system is integral. The level of preparation that broadcasters are undertaking for 4K is substantially higher than it was for HD in its beginnings. From a physical point of view, the bandwidth that 4K consumes and the storage space it takes up is much bigger. Broadcasters will need more storage, increased network capacity to incorporate new codecs to handle 4K. The job of the MAM system is to manage all of these changes.

The introduction of 4K in a MAM system like Viz One, will not change many basic services such as file management, load balancing, partial ret
