Content Storage Management
Content storage management (CSM) is a technique for the evolution of traditional media archive technology used by media companies and content owners to store and protect valuable file-based media assets. CSM solutions focus on active management of content and media assets regardless of format, type and source, interfaces between proprietary content source/destination devices and any format and type of commodity IT centric storage technology. These digital media files (or assets) most often contain video but in rarer cases may be still pictures or sound. A CSM system may be directed manually but is more often directed by upper-level systems, which may include media asset management (MAM), automation, or traffic. Typically, CSM systems are server-based software applications that reside between the media network, which connects the various broadcast or manipulation devices, and the storage network, which connects the nearline and archive storage tiers.

Media (communication)
In mass communication, media are the communication outlets or tools used to store and deliver information or data. The term refers to components of the mass media communications industry, such as print media, publishing, the news media, photography, Movie theater, cinema, broadcasting (radio and television), digital media, and advertising. The development of early writing and paper enabling longer-distance communication systems such as mail, including in the Achaemenid Empire, Persian Empire (Chapar Khaneh and Angarium) and Roman Empire, can be interpreted as early forms of media. Writers such as Howard Rheingold have framed early forms of human communication, such as the Lascaux, Lascaux cave paintings and early writing, as early forms of media. Another framing of the history of media starts with the Chauvet Cave paintings and continues with other ways to carry human communication beyond the short range of voice: smoke signals, Trail blazing, trail markers, and sculpture.

Ethernet
Ethernet () is a family of wired computer networking technologies commonly used in local area networks (LAN), metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3. Ethernet has since been refined to support higher bit rates, a greater number of nodes, and longer link distances, but retains much backward compatibility. Over time, Ethernet has largely replaced competing wired LAN technologies such as Token Ring, FDDI and ARCNET. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with switches. Over the course of its history, Ethernet data transfer rates have been increased from the original to the latest , with rates up to under development. The Ethernet standards include several wiring and signaling variants of the OSI physical layer. Systems communicating over Ethernet ...

File System
In computing, file system or filesystem (often abbreviated to fs) is a method and data structure that the operating system uses to control how data is stored and retrieved. Without a file system, data placed in a storage medium would be one large body of data with no way to tell where one piece of data stopped and the next began, or where any piece of data was located when it was time to retrieve it. By separating the data into pieces and giving each piece a name, the data are easily isolated and identified. Taking its name from the way a paper-based data management system is named, each group of data is called a "file". The structure and logic rules used to manage the groups of data and their names is called a "file system." There are many kinds of file systems, each with unique structure and logic, properties of speed, flexibility, security, size and more. Some file systems have been designed to be used for specific applications. For example, the ISO 9660 file system is designe ...

Material Exchange Format
Material Exchange Format (MXF) is a container format for professional digital video and audio media defined by a set of SMPTE standards. A typical example of its use is for delivering advertisements to TV stations and tapeless archiving of broadcast TV programs. It is also used as part of the Digital Cinema Package for delivering movies to commercial theaters. Summary MXF, when used in the form of "Operational Pattern OP1A" or "OPAtom", can be used as a ''container'', ''wrapper'' or ''reference file'' format which supports a number of different streams of coded "essence", encoded in any of a variety of video and audio compression formats, together with a metadata wrapper which describes the material contained within the MXF file. Other "Operational Patterns" can contain or reference multiple materials, just like a simple timeline of a video editing program. MXF has full timecode and metadata support and is intended as a platform-agnostic stable standard for future professiona ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Replication (computing)
Replication in computing involves sharing information so as to ensure consistency between redundant resources, such as software or hardware components, to improve reliability, fault-tolerance, or accessibility. Terminology Replication in computing can refer to: * ''Data replication'', where the same data is stored on multiple storage devices * ''Computation replication'', where the same computing task is executed many times. Computational tasks may be: ** ''Replicated in space'', where tasks are executed on separate devices ** ''Replicated in time'', where tasks are executed repeatedly on a single device Replication in space or in time is often linked to scheduling algorithms. Access to a replicated entity is typically uniform with access to a single non-replicated entity. The replication itself should be transparent to an external user. In a failure scenario, a failover of replicas should be hidden as much as possible with respect to quality of service. Computer scientis ...

Storage Resource Management (SRM)
In computing, storage resource management (SRM) involves optimizing the efficiency and speed with which a storage area network (SAN) utilizes available drive space.SearchStorage.com Definitions. What is storage resource management” Retrieved September 9, 2009. History Data growth averages around 50% to 100% per year and organizations face rising hardware and storage management costs. Storage professionals who face out-of-control data growth are looking at SRM to help them navigate the storage environment. SRM identifies under-utilized capacity, identifies old or non-critical data that could be moved to less expensive storage, and helps predict future capacity requirements. SRM evolved beyond disk quota, quota management. it included functions such as storage area network (SAN) management. References Storage software {{storage-software-stub ...

Abstraction Layer
In computing, an abstraction layer or abstraction level is a way of hiding the working details of a subsystem. Examples of software models that use layers of abstraction include the OSI model for network protocols, OpenGL, and other graphics libraries, which allow the separation of concerns to facilitate interoperability and platform independence. Another example is Media Transfer Protocol, which allows shared access and requires no common file system support but restricts user control compared to mass storage with block-level access. In computer science, an abstraction layer is a generalization of a conceptual model or algorithm, away from any specific implementation. These generalizations arise from broad similarities that are best encapsulated by models that express similarities present in various specific implementations. The simplification provided by a good abstraction layer allows for easy reuse by distilling a useful concept or design pattern so that situations, where it m ...

Stub File
A stub file is a computer file that appears to the user to be on disk and immediately available for use, but is actually held either in part or entirely on a different storage medium. When a stub file is accessed, device driver software intercepts the access, retrieves the data from its actual location and writes it to the file, then allows the user's access to proceed. Typically, users are unaware that the file's data is stored on a different medium, though they may experience a slight delay when accessing such a file. File stubbing, the act of creating stub files, is a Hierarchical storage management (HSM) concept. Purpose The usual purpose of stubbing files is to move data from an expensive high-speed storage device such as a computer's hard drive to lower cost storage such as a magnetic tape, or an electro-optical disk, while not requiring users to know how to use specialised storage software to retrieve the data. It also allows a system manager to enforce the use of low ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hierarchical Storage Management
Hierarchical storage management (HSM), also known as Tiered storage, is a data storage and Data management technique that automatically moves data between high-cost and low-cost storage media. HSM systems exist because high-speed storage devices, such as solid state drive arrays, are more expensive (per byte stored) than slower devices, such as hard disk drives, optical discs and magnetic tape drives. While it would be ideal to have all data available on high-speed devices all the time, this is prohibitively expensive for many organizations. Instead, HSM systems store the bulk of the enterprise's data on slower devices, and then copy data to faster disk drives when needed. The HSM system monitors the way data is used and makes best guesses as to which data can safely be moved to slower devices and which data should stay on the fast devices. HSM may also be used where more robust storage is available for long-term archiving, but this is slow to access. This may be as simple as an ...

Data Integrity
Data integrity is the maintenance of, and the assurance of, data accuracy and consistency over its entire Information Lifecycle Management, life-cycle and is a critical aspect to the design, implementation, and usage of any system that stores, processes, or retrieves data. The term is broad in scope and may have widely different meanings depending on the specific context even under the same general umbrella of computing. It is at times used as a proxy term for data quality, while data validation is a prerequisite for data integrity. Data integrity is the opposite of data corruption. The overall intent of any data integrity technique is the same: ensure data is recorded exactly as intended (such as a database correctly rejecting mutually exclusive possibilities). Moreover, upon later Data retrieval, retrieval, ensure the data is the same as when it was originally recorded. In short, data integrity aims to prevent unintentional changes to information. Data integrity is not to be confus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metadata
Metadata is "data that provides information about other data", but not the content of the data, such as the text of a message or the image itself. There are many distinct types of metadata, including: * Descriptive metadata – the descriptive information about a resource. It is used for discovery and identification. It includes elements such as title, abstract, author, and keywords. * Structural metadata – metadata about containers of data and indicates how compound objects are put together, for example, how pages are ordered to form chapters. It describes the types, versions, relationships, and other characteristics of digital materials. * Administrative metadata – the information to help manage a resource, like resource type, permissions, and when and how it was created. * Reference metadata – the information about the contents and quality of statistical data. * Statistical metadata – also called process data, may describe processes that collect, process, or produce st ...
