Content storage management

Content storage management ( CSM ) is a technology for the evolution of traditional media archive technology used by media companies and content owners. MSC solutions focus is active management of happy and media assets Regardless of size, type and source, proprietary interfaces entre glad source / destination devices and Any size and the type of commodity IT centric storage technology. These digital media files (or assets) MOST Often Contain video goal in rarer cases May be still pictures or sound. A CSM system may be directed by upper level systems,

Typically, CSM systems are server-based software application That lies entre les media network, qui connects the various broadcast or handling devices, and the storage network , qui connects the nearline and archive storage thirds. Reviews The most basic function of MSCs is the automated retrieval of high-resolution digital content (or gasoline) Either from a data tape library (with the aid of a robot ), or from a data server, and the delivery of That happy Either to a Workstation , playout or editing device. CSM also performs this process in reverse – moving content back to storage. In a given media operation, CSM may be used to facilitate content manipulation and repurposing; Systems interoperability through high and low bit rate content transcoding ; And / or site-to-site content replication for disaster recovery.

MSC solutions comply with the Well Known Reference Model for an Open Archival Information System (OAIS), qui is Fundamental to long-term archive and content preservation in file-based environments and are caractérisée by a set of application-specific functionality , qui can include :

  • Interfaces to proprietary media creation and consumption devices
  • Transcoding and rewrapping technologies to ensure compatibility of content in its source, format, encoding rates, aspect ratio, content container
  • IT-centric storage devices allowing limitless or near limitless storage expansion
  • Integration with various network technologies including Ethernet , Fiber Channel , etc. And many protocols such as SCSI , TCP / IP , etc.
  • Full compliance with the OAIS model Well Established Allowing combination of reference metadata , media and Any Other Key Elements, ranging qui year overall asset Targeted to storage and preservation goals
  • Subjective content analysis for file-based audio / video content
  • Data integrity and validation checks such as checksums, etc.
  • Analytics engines for capturing, measuring and reporting on all aspects of the system including network bandwidth, read / write error rates, data storage profiles, etc.
  • Features for local and geographically distributed disaster recovery applications
  • Extensibility of incremental expansion of the system

History of CSM

The concept of CSM was first introduced in November 2006 by Brian Campanotti and Rino Petricola from Front Porch Digital Inc., one of the providers of CSM solutions. CSM solutions have their origins in archive management systems, but their functionality is considerably broader. Likewise, CSM systems resemble hierarchical storage management (HSM) systems in that both migrate among third-party storage, but they are distinct. For example, CSM software is media-specific, with internal decision-making models based on media-centric parameters, and with programmatic interfaces specific to control and management by broadcast business systems such as traffic, inventory, and automation. CSM groups related assets (typically video file and related multilingual audio files) into a single managed object for storage and retrieval. CSM does not use stub files , which are directly related to files. CSM migrates files by copying them from one system to another. And finally, by definition, CSM does not stand alone as functions as an abstraction layer between disparate systems and various storage devices, broadcast editing and playout devices and even end consumer devices such as set top boxes and web streaming sites.

Reviews The most significant differentiator entre CSM and HSM solutions is the différence entre entre tiered storage migration Fundamental to HSM and the active storage management Fundamental to CSM solutions. Conceptually, HSM solutions are used to evaluate the quality of the data. And treat each file as a separate entity. ALTHOUGH CSM solutions aussi manage tiered storage (ALTHOUGH not SPECIFICALLY limited to-any kind, amount or storage technology) but do not Rely on static policies aim Rather Can Be livingroom policies That can be assigned dynamically to content Reviews entering the system and Govern replication policies, storage persistence, Age-based migration, as well as transcoding, rewrapping, reformatting and subjective quality analysis. In some cases, the content within the CSM system is intentionally different. As an example, content Reviews entering a MSC solution in a legacy media formats Such As Pinnacle MPEG2 May be intentionally transcoded to MPEG2 IMX50 and wrapped in an industry standard size Such as MXF to Ensure along term compatibility with other systems connected to the CSM solution. These media-centric workflows are not inherently supported by HSM solutions. The content within the CSM system is intentionally different. As an example, content Reviews entering a MSC solution in a legacy media formats Such As Pinnacle MPEG2 May be intentionally transcoded to MPEG2 IMX50 and wrapped in an industry standard size Such as MXF to Ensure along term compatibility with other systems connected to the CSM solution. These media-centric workflows are not inherently supported by HSM solutions. The content within the CSM system is intentionally different. As an example, content Reviews entering a MSC solution in a legacy media formats Such As Pinnacle MPEG2 May be intentionally transcoded to MPEG2 IMX50 and wrapped in an industry standard size Such as MXF to Ensure along term compatibility with other systems connected to the CSM solution. These media-centric workflows are not inherently supported by HSM solutions. Reviews entering a happy CSM solution in a legacy media Such as Pinnacle MPEG2 formats May be intentionally transcoded to MPEG2 IMX50 and wrapped in an industry standard Such As Format MXF to Ensure along term compatibility with other systems connected to the CSM solution. These media-centric workflows are not inherently supported by HSM solutions. Reviews entering a happy CSM solution in a legacy media Such as Pinnacle MPEG2 formats May be intentionally transcoded to MPEG2 IMX50 and wrapped in an industry standard Such As Format MXF to Ensure along term compatibility with other systems connected to the CSM solution. These media-centric workflows are not inherently supported by HSM solutions.

Based on the content centric focus of CSM solutions, they do not have legacy reliance on key HSM traits such as the use of stub files, which must remain on the original file from where the file was migrated to cheaper third of storage. This article is a preview generated by EVS Publishing, permission to subscribe to the CSM solutions.

The HSM system takes ownership and migrating the content to other thirds of disk. As the HSM systems do not have the ability to directly interface with these various broadcast and media devices such as encoders, video servers, editing systems, etc. (MAM) system or other application specific utility.

MSC solutions extend the realm of content control and management Directly from the internals of the content source and destination devices through Any number and types of mass storage devices (disk, tape, optical, offline, etc.) all managed by configurable smart similar policies in Concept to information lifecycle policies (ILM)

CSM solutions are not meant to be used in the same way as the CSM system. To be restored. All content stored within a CSM storage infrastructure is equally viable for restore operations at any point of time and often no reliable predictability is possible.

The CSM solutions are also a key driver of the CSM solution. In terms of preservation, high-value content (historical, cultural, monetary, etc.) can be assigned differing CSM solutions via WAN connectivity providing distribution as well as disaster recovery functionality.

Example of CSM in Broadcast An example of the role of CSM in a broadcast is as follows: A movie is ingested into the content owner’s workflow leveraging an encoding device and a control system such as automation or MAM. This article is a preview generated by EVS Complaining Pages 2 of 2 Next end of document in the Microsoft Windows environment . An editor uses the MAM system to view the proxy generated by the CSM solution, and from his desktop workstation selects shots for use in a promo for the movie. The editor Then Sends his / her edit decision list (EDL) to the MSC system, qui restores to the editing system only the Desired broadcast-quality segments is based mark in and mark out timecode values defined Within it. The CSM system then transcodes or rewraps the segments as necessary, so they can be used by the editor in the creation of the promo. Once the editor completes the promotion, the editing system sends it via the CSM system (which can also repeat the replication and proxy generation process) to the on-air video servers for playout to air. So they can be used by the editor in the creation of the promo. Once the editor completes the promotion, the editing system sends it via the CSM system (which can also repeat the replication and proxy generation process) to the on-air video servers for playout to air. So they can be used by the editor in the creation of the promo. Once the editor completes the promotion, the editing system sends it via the CSM system (which can also repeat the replication and proxy generation process) to the on-air video servers for playout to air.
