Media Asset Management Flashcards
What is a typical content management stack comprised of?
- Content Management
- File System
- Storage
What is the role of Content Management in a content management stack?
Content Management is a database which contains the application metadata.
What is the role of a File System in a Content Management Stack?
- The file system contains metadata such as file attributes and permissions.
- Identifies files using the Universal Naming Convention (UNC) path address.
Why would File System Middleware be implemented in a Content Management Stack?
- Allows for a global file system which is comprised of multiple different file systems.
- Allows for the implementation of life cycle management.
What is BPM?
Business Process Management (BPM) is a discipline in operations management that uses various methods to discover, model, analyze, measure, improve, optimize, and automate business processes.
What are the key functions of Digital Asset Management?
- Cataloguing assets so they are organised and searchable.
- Verifying the integrity of assets (i.e. are they acceptably safe and complete).
- Verifiying the security of assets (ensuring they have the correct copyright protection mechanisms)
- Backing up of Assets.
- Processing assets, such as the conversion of assets to other formats, merging and collating them.
- Delivering assets to distribution, etc.
What is MAM used for?
The movement of media throughout the broadcast workflow (broadcast/production/post-production).
What is a “Watch folder”?
A watch folder is a memory location which will execute a pre-configured operation to any file which is placed within it.
What types of MAM are used?
- Production
- Archive
- Enterprise
- B2B
- Distribution
What is Production MAM used for?
Production Media Asset Management (MAM) is used to manage media which is involved in the process of a current production.
What is archive MAM used for?
- Archive Media Asset Management is used for long term archival.
- Defines the lifecycle of an asset and manages it accordingly.
What is Enterprise MAM used for?
- Enterprise Media Asset Management allows for collaboration across the entire media enterprise.
- The scope and methods of doing so are defined by the Business Process Management (BPM)
What is B2B MAM used for?
B2B Media Asset Management is used for the sharing of assets between different businesses, such as the sale / purchase of media.
What is Distribution MAM used for?
The Distribution Media Asset Management occurs at the point of distribution.
What components is the Media Asset Management comprised of?
- Core
- Design
- Media Services
- Annotation
- Connection to other systems
- Maintainability
What is the function of the Core in Media Asset Management?
- A searchable and organised media catalogue.
- Essence management including the operation of watch folders and support for multiple essences.
- Media Viewing.
What is defined in the Design of Media Asset Management?
- The Scale, Performance and Redundancy.
- The Openness and API configuration.
- Which essences will be natively supported.
- If Business Process Management (BPM) will be implemented.
- Quality of Service
- Essence management.
What Media Services are used within Media Asset Management?
- Transcoding
- Quality Control
- Transcription
- Video Player
What is the function of Annotation in Media Asset Management?
- Defines how to tag assets
- Defines what metadata should be generated
What is a side car file?
- A side car file is an added on file which can contain further metadata associated with an asset.
- Can contain a “handshake” to ensure reception of a sent asset.
What Maintainability features can be contained in Media Asset Management?
- A dashboard of system health.
- The enabling of partial shutdown / continued working.
- The configuration of Key Performance Indicators (KPIs).
What is NRCS?
A News Room Computer System which is an application of Media Asset Management and allows for communication with video servers, audio servers, still stores, and character generators for broadcast production.
What is HSM?
Hierarchical Storage Management (HSM) is a data storage technique, which automatically moves data between high-cost and low-cost storage media.
What is CMS?
A Content Management System (CMS) is a computer application that supports the creation and modification of digital content. It typically supports multiple users in a collaborative environment.
What are the features of a Centralised Multimedia Content Catalogue?
- Gives users immediate access to all content.
- Allows for tracking and searching of metadata.
- Uses Business Process Management (BPM) to automate back-office and end-user tasks.
- Has broadcast analysis tools.
- Allows for servers to be load balanced to increase efficiency.
What is TCO?
Total Cost of Ownership (TCO) is a financial estimate intended to help buyers and owners determine the direct and indirect costs of a product or system.
What is LTFS?
Linear Tape File System (LTFS) is a file system that allows files stored on magnetic tape to be accessed in a similar fashion to those on disk or removable flash drives. It requires both a specific format of data on the tape media and software to provide a file system interface to the data.
What are the attributes of Tier 0 in Tiered Archival Storage?
- Comprises 1% - 3% of system storage.
- The content is 1 day old or less.
- Deemed as High Value and High Performance.
What are the attributes of Tier 1 in Tiered Archival Storage?
- Comprises 12% - 20% of system storage.
- The content is 1 - 3 days old.
- Deemed as Mission Critical.
What are the attributes of Tier 2 in Tiered Archival Storage?
- Comprises 20% - 25% of system storage.
- The content is 3 - 7 days old.
- Deemed as Less Critical / Recoverable.
What are the attributes of Tier 3 in Tiered Archival Storage?
- Comprises 43% - 60% of system storage.
- The content is 7 - 39 days old.
- Deemed as Long Term Archival.
What are the attributes of Tier 4 in Tiered Archival Storage?
- The content is 90+ days old.
- Deemed as Historically Archived Data.
What advantages does digital tape offer as a storage medium?
- Tape media life is 30+ years.
- Can be faster than disks as Random Array of Independent Disks (RAID) rebuild times increase as capacity grows.
What is RAID?
Redundant Array of Independent Disks (RAID) is a data storage virtualization technology that combines multiple physical disk drive components into one or more logical units for the purposes of data redundancy, performance improvement, or both.
How does RAID Parity work?
Random Array of Independent Disks (RAID) Parity works by calculating the data in two drives and storing the results on a third.
What is RAID Level 0?
Random Array of Independent Disks (RAID) Level 0 is where disks are striped (containing entirely different information) which improves performance but reduces redundancy.
What is RAID Level 1?
Random Array of Independent Disks (RAID) Level 1 is where disks are mirrored (containing identical copies of information) which reduces performance but improves redundancy.
What is RAID Level 5?
Random Array of Independent Disks (RAID) Level 5 requires a minimum of three disks
- Is the most cost effective option, both good performance and redundancy.
- Blocks are redundant as parity is distributed across all disks.
- Recommended for setups comprised of mainly read operations as write operations are significantly slower.
What is RAID Level 10?
Random Array of Independent Disks (RAID) Level 10 is where all disks are both striped and mirrored.
- This increases cost but also increases redundancy and performance.
- Best for use in mission critical contexts.
