This Glossary was developed on 2008/9 by EMA's Digital Council and is a living document. Please submit updates and additions to firstname.lastname@example.org for vetting through the Digital Council. (updated April 2013)
AAF (Advanced Authoring Format): Refers to the standardized metadata definitions that are used to exchange metadata between creative content workstations. This “format” has been created primarily for postproduction use. The AAF includes a rich set of composition metadata that can be used to describe the components making up a program or production. It is worth noting that the definition does provide for “essence” exchange as well as metadata exchange.
AGC: Automatic Gain Control. A circuit which automatically adjusts the input gain of a device, in order to provide a safe and consistent signal level. AGCs can be handy features, but professional applications often require manual gain control for optimum results.
Adobe Flash Player: A lightweight browser plug-in and rich internet application runtime that delivers consistent and engaging user experiences, stunning audio/video playback, and pervasive reach. It is the foundation of the next generation of Adobe Flash Platform, built on open technologies and open-source community participation.
Aliasing: Distortion of an image file or sound recording due to insufficient sampling or poor filtering. Aliased images appear as jagged edges, aliased audio produces a buzz.
Alpha Channel: A special channel in some digital images reserved for transparency information.
Amperage: The amount of electrical current transferred from one component to another.
Ambient: The environmental conditions, e.g. surrounding light and sound.
Aperture: Literally means "opening". The camera iris; the opening which lets light through the lens. By adjusting the size of the aperture, the amount of incoming light is controlled. The aperture size is measured in f-stops.
Application Programming Interface (API): A set of routines, protocols, and tools for building software applications. An API expresses a software component in terms of its operations, inputs, outputs, and underlying types. An API defines functionalities that are independent of their respective implementations, which allows definitions and implementations to vary without compromising each other. A good API makes it easier to develop a program by providing all the building blocks. A programmer then puts the blocks together.
ASF: Windows Media file format ending with the extension .asf. Used for delivering streaming video.
Aspect Ratio: The ratio of width to height of an image. Can be expressed as a number, or a relationship between two numbers. For example, the standard television screen ratio is 4:3 (4 units wide by 3 units high) or 1.33 (the width is 1.33 times the height). The new "wide screen" television ratio is 16:9 (1.78), and many new video cameras have the option to record using this format. Theatrical film aspect ratios vary, but the most common is 18.5:10 (1.85).
Asset: An original source or a high-quality digital content element that can be integrated into a larger work.
ASX: Windows Media file format ending with the extension .asx. This is a metafile which works in conjunction with ASF files for delivering streaming video.
AVI: "Audio Video Interleaved". A common digital video format, in which the audio is interleaved as "packets", into the video frames.
AVOD(Ad-SupportedVideo On Demand): Ad-supported content made available on an ondemand basis for streaming end users. Examples of AVOD include ABC Go, Crackle, Hulu, Popcornflix, and YouTube. Such services are primarily made available to the end user at no charge, though in some instances a ‘freemium’ or hybrid AVOD/SVOD model is employed where only a portion of the service’s catalog is made available for free, with the rest behind a subscription pay wall.
Bundle: A group of related assets sold jointly for a single price.
Bandwidth: A measure of the amount of data that can travel through a network. Once measured in kilobits per second (Kbps), megabits (1 million bits) per second are more relevant in the broadband era.
Bit Rate: The number of bits transmitted per second. Dial-up maxes out at 56 kilobits per second while broadband via DSL, cable modem, fiber optic cable or WiFi can transmit anywhere from 400k to 8 megabit per second and beyond.
Blog/Vlog: Online text or video diaries covering a range of topics, from personal reflections to highly specialized industry news. Many web companies maintain their own corporate blog where informal announcements are made to their communities of users. More popular blogs earn ad revenue, break news, attract buyout offers and have even been known to influence national debate or stock prices. Platforms such as Google-owned Blogger, TypePad and WordPress have turned blogging into one of the easiest ways for people to maintain a constantly updated web presence.
Buffering: A process used as a part of streaming media technologies whereby a certain amount of data is fed into the player to allow it to begin playing before fully downloading the file.
Byte: One of the basic units for measuring digital information, especially relevant to understanding storage capacity on computer disks. 8 bits comprise a byte. Roughly 1000 bytes equals one kilobyte. 1000 kilobytes is one megabyte or meg. 1000 megabytes is a gigabyte.
Capture (a.k.a. ingest): The process of digitizing audio and video content from an analog format.
Closed Captioning: Captions are words displayed on a television screen that explains the audio of a program to let viewers who are deaf or hard of hearing understand the dialogue and action of a program at the same time. Closed captioning is enabled on a television set by a decoder that's built in the television. The United States government requires that decoders be built into television sets 13 inches or larger that are sold in the U.S. Closed captioning can be turned on or off by the viewer, according to the Federal Communications Commission.
Codec (Coder/Decoder): Software or driver that adds support for certain video/audio formats to an operating system. An operating system using a codec will recognize the format the codec is built for and "decode" it allowing you to play the audio/video file, or in some cases it will change the file format ("encode") allowing it to play. The most commonly used codecs are installed automatically on most computers. Examples of codecs are MPEG-2, DivX, and MPEG-1.
Compression: Reducing the quantity of data used to represent digtal video images by removing redundancies in digital data files so that less space is required. Two main forms of compression are lossy and lossless. Lossless compression takes away only a certain amount of data so that it can be returned to its original complete state, while lossy compression will sacrifice more data to further reduce space. MPEG-4 is an example of a lossy compression.
Conditional Download: A file which is fixed into a time-limited or play count-limited download. Usually cannot be burned or transferred and may be deleted or disabled for the end users storage device no later than has been authorized.
Copyright Notice: Indication that the work is copyrighted, the date of the copyright, and the copyright owner. (E.g., "© 2008 Twentieth Century Fox Film Corporation".) The Copyright Notice is distinct from copyright licensing information. See also Perceptible Copyright Notice.
CPM: Cost Per Thousand - (the letter "M" in the abbreviation is the Roman numeral for one thousand). CPM is used by Internet marketers to price ad banners. Sites that sell advertising will guarantee an advertiser a certain number of impressions (number of times an ad banner is downloaded and presumably seen by visitors.), then set a rate based on that guarantee times the CPM rate. A Web site that has a CPM rate of $25 and guarantees advertisers 600,000 impressions will charge $15,000 ($25 x 600) for those advertisers' ad banner.
CSS (Constant Scramble System): The protection system that prevents movies from being illegally duplicated, protecting the intellectual property of the manufacturers, producers and writers of audiovisual content from theft. CSS is a two-part system for which manufacturers of both the movie content and hardware or software (players) purchase licenses.
Data Rate: An attribute assigned to a media file by a compression utility. It is a measure of the amount of digital information transmitted in a given unit of time—usually a second. Thus, a video could be encoded to play back at a rate of 500 kb/s.
DECE: Digital Entertainment Content Ecosystem (DECE) is the international cross-industry group that runs UltraViolet. DECE was originally called Open Market. DECE member companies developed the policies, specifications, and license agreements.
DIAL: DIscovery And Launch - a simple protocol that 2nd screen devices can use to discover and launch apps on 1st screen devices.
Digital Asset: Any item of text or media that has been formatted into a binary source that includes the right to use it. A digital file without the right to use it is not an asset.
Digital Asset Management: how you take in, handle and distribute everything you have in digital form
Digital Supply Chain: The process of the delivery of digital media, be it music or video, by electronic means, from the point of origin (Content Provider) to destination (consumer).
Download: The process of copying data files from a server to a playback device.
DRM (Digital Rights Management): DRM refers to the administration of usage rights in a digital environment. DRM solutions enforce the business rules set by the content owner often by managing "keys" between users and a server.
DST: Digital Sell Through. See EST.
DTO: Download To Own. See EST.
DVI (Digital Video Interface): A uniform connector that can accommodate both digital and analog video signals, often used between computers and monitors. The DVI connector on a device is given one of three names, depending on which signal it implements (DVI-D for digital only, DVI-A for analog only, DVI-I for both digital and analog, and DVI-DL for a connector that includes a second data link for high resolution displays. ALT: An interface standard for connecting both analog and digital monitors. It offers a high bandwidth for uncompressed digital data transfer, and can carry digital copy protection
EIDR: The Entertainment Identifier Registry manages the issuance of universal identifiers for a broad array of audio visual objects.
Embed Tag: An HTML tag used to place a media file (such as an audio, video, or Flash file) into a web page. The embed tag defines an area on the page in which the media file will appear if it involves graphic elements, helps the browser understand what type of file it is, and specifies other info such as whether the file will play automatically when the page loads. Embedded media are contrasted to media controlled through a separate player, such as when the Windows Media player pops up over your web browser to display a video.
Encode: Compressing a file (audio, video or picture) into another format, usually taking up less space. Common video encoding methods are DivX, MPEG-1, MPEG-2and MPEG-4.
Encryption: Locking content by applying an algorithm in conjunction with an encryption key. Encrypted content cannot be viewed unless it is decrypted, requiring the corresponding encryption key. In most systems, the encryption key and the decryption key are the same, and the key management protocol defines the scheme that is used to securely transfer the key to the intended receiver of the encrypted content. In public key systems, the encryption and decryption keys are not the same, and knowledge of one doesn't allow the other to be determined.
Episode: A single part (similar to a chapter) of a series or compilation, usually first distributed via broadcasting, webcasting or podcasting on a single date.
EST: Electronic Sell Through. A licensed reproduction without limitation on the ordinary use and enjoyment of the resulting lawfully made copy. (The "To Own" appendage is a misnomer, given that ownership of the medium onto which a file is downloaded does not change. Anyone who downloads a file under a valid license is the owner of a lawfully made copy, no matter what restrictions may be placed on access to the file.)
Fast Track: A decentralized P2P network that powers P2P applications.
Fingerprinting: A technology to protect multimedia from unauthorized reproduction which embeds a unique ID into each user's copy that can be extracted to help identify culprits when an unauthorized leak is discovered. ALT: An extended watermarking technique which embeds the identity of the end user into the content This can be used to trace the source of copyright infringement.
Flash: The authoring tool and format developed by Macromedia (acquired by Adobe Systems in 2005) to create content for digital platforms such as web applications, games, movies. It has become the preferred standard for adding animation and interactivity to web pages and is commonly used to integrate video and develop rich media applications.
Frames Per Second (fps): The number of video frames displayed each second (also called frame rate). Continuous motion is believed to be achieved at about 17 fps. A common standard for video delivered over the web is 15 fps, which reduces file sizes substantially (since most video is shot at roughly 30 fps) but still but allows for fairly smooth motion.
Full Motion: Refers to NTSC-quality video—a video signal that is 30 fps, and at least 640x480 pixels in size.
GPRS (General Packet Radio Service): A non-voice value-added service that allows information to be sent and received across a mobile telephone network, supplementing Circuit Switched Data and Short Messaging Service.
H.264 (aka MPEG-4 Part 10): A video encoding layer of MPEG-4, officially known as AVC.
HD (High Definition): HD comes in three different formats, all in widescreen format (16:9), and provides the highest resolution and picture quality of all digital formats. Combined with digitally enhanced sound technology. The first (720p) features 720 x 1280 pixel resolution with progressive scanning. The second current high definition format (1080i) features greater resolution (1080 x 1920 pixels), but with interlaced scanning. The third (1080p) is currently the ultimate high definition format, with 1080 x 1920 pixel resolution (in the 16:9 ratio) and progressive scanning. Because of the high bandwidth requirements, this format is not yet used for television broadcasts, although Blu-ray high-definition DVD formats are be capable of a 1080p picture.
HDCP (High-Bandwidth Digital Copy Protection): A specification developed by Intel Corporation to "protect" digital audio and video content as it travels across Digital Visual Interface (DVI) or High Definition Multimedia Interface (HDMI)connections. HDCP protects uncompressed digital content from being transmitted to a non-HDCP compliant device (such as a DVD recorder), as data transmissions are permitted only between HDCP compliant devices connected to each other.
HDMI (High Definition Multimedia Interface): A high-speed serial interface, capable of transmitting standard, enhanced, or high-definition video. The standard supports transmissions of up to 2.2 gigabits per second and resolutionsup to 1920x1080p at 30Hz. All data is sent uncompressed, to minimize additional artifacts from recompression - that is, there is no D/A or A/D conversions needed. Up to eight channels of 192KHz audio are supported. The connector is more compact as well, resembling a USB connector.
HDMI Video Up-conversion: Converts incoming composite, S-video, and component signals up to HDMI standard.
Hotspotting: The practice of embedding hyperlinks within online video to enable users to click on actors, characters’ articles of clothing or other objects within the frame for more information or the opportunity to purchase.
HTML (HyperText Markup Language): The rules that govern the way documents are created so they can be read by a world-wide-web browser.
HTTP (HyperText Transport Protocol): The protocol through which web pages are transmitted over the Internet.
Hyperlink: A web link in a given document to information within another document. These links are usually represented by highlighted words or images. The user also has the option to underline these hyperlinks.
HTTP Streaming: A form of streaming in which media files begin to play before they are downloaded entirely. This means that they can be sent via HTTP and don't require specialized server software such as RealMedia files do. Also called Progressive Download.
Ingest: The stage in which the compressed file and metadata are put into the digital asset management system.
Internet Protocol (IP): The format of packets, and the addressing scheme. Most networks combine IP with a higher-level protocol called Transmission Control Protocol (TCP), which establishes a virtual connection between a destination and a source. IP allows you to address a package and drop it in the system, but there's no direct link between you and the recipient. TCP/IP, on the other hand, establishes a connection between two hosts so that they can send messages back and forth for a period of time.
IPTV (Internet Protocol TV): A system where a digital television service is delivered using Internet Protocol over a network infrastructure, which may include delivery by a broadband connection. Content, instead of being delivered through traditional broadcast and cable formats, is received by the viewer through the technologies used for computer networks. IPTV is typically supplied by a service provider using a closed network infrastructure. This closed network approach is in competition with the delivery of TV content over the public Internet, called Internet Television.
ISAN (International Standard Audiovisual Number): A voluntary numbering system for the identification of audiovisual works, providing a unique, internationally recognized, and permanent reference number for each audiovisual work registered in the ISAN system. The ISAN remains the same for an audiovisual work regardless of the format in which it is distributed.
iVOD (Internet Video on Demand): The temporary license (i.e., a rental) of a program for a limited and pre-determined viewing period (such as 24 or 48 hours) for on-demand viewing by an end-user. The program may be downloaded and stored locally on the end-user’s device, or accessed online via streaming.
Licensor: A party granting rights (typically copyrights and rights of publicity) under a license agreement. Includes a Licensee who is authorized to sublicense the rights. Licensors typically grant the right to reproduce or perform the work publicly.
Licensee: A party obtaining rights under a license agreement.
Licensing Agent: A third party, that may or may not be the Copyright owner, that provides services for or on behalf of Licensee under the Licensee 's supervision and in accordance with the terms and conditions of an agreement. Otherwise known as Contractor.
LIVE TV: A subscription-model service where content is streamed live to an internet-connected device for viewing by the end-user (see OTT device examples above). Some people believe IPTV is OTT, but IPTV operates in a closed system or a dedicated, managed network controlled by thelocal multichannel video programming distributor (MVPD): a cable, satellite, telephone, or fiber company like U-verse (AT&T). IPTV means Internet Protocol TV and refers to the technology being utilized in the content’s delivery, not the license or business model being employed. OTT TV differs from IPTV as it transmits streams using HTTP (Hypertext Transfer Protocol), the protocol which has been used for decades to transport web pages over the internet.
Long Tail: Use of the phrase the long tail in business as "the notion of looking at the tail itself as a new market" of consumers was first coined by Chris Anderson. "The theory of the Long Tail is that our culture and economy is increasingly shifting away from a focus on a relatively small number of "hits" (mainstream products and markets) at the head of the demand curve and toward a huge number of niches in the tail. As the costs of production and distribution fall, especially online, there is now less need to lump products and consumers into one-size-fits-all containers. In an era without the constraints of physical shelf space and other bottlenecks of distribution, narrowly-target goods and services can be as economically attractive as mainstream fare." - Chris Anderson, Wired, 9/8/05
Mashup: A web service or software tool that combines two or more tools to create a whole new service. A famous example is ChicagoCrime, which merges Google Maps with the Chicago police department's crime tracking web site to offer a map of crime in different parts of Chicago. The term is also used to describe user generated remixes of content from different sources.
Metadata: The information that identifies and describes the contents of a medium. This information can include media-specific information such as: Title, artist(s), production company, seasonal/episodic description, original release date, etc. Metadata can also include business-related information such as: pricing and availability.
MPAA (The Motion Picture Association of America): The non-profit trade association formed to advance the business interests of movie studios. Its members include The Walt Disney Company, Sony Pictures, Paramount Pictures, 20th Century Fox, Universal Studios and Warner Brothers. The MPAA administers the voluntary film rating system.
MPAA Rating: Administered by the MPAA , this rating system is used in the United States and its territories to rate a film's thematic and content suitability for certain audiences. It is one of various motion picture rating systems used to help patrons decide what movies are appropriate for children, for adolescents, and for adults. Current ratings are G, PG, PG-13, R, and NC-17. Legacy ratings no longer issued include GP, M and X.
Network: The provider of programming to a series of affiliated local television stations. For purposes of metadata standards, it is the local (meaning nation of origin) network that originally broadcast a television series.
NTSC: The video input signal formats used in North America and Japan. Full-sized NTSC has 525 total lines of resolution (480 visible) per frame.
Open Captioning: Captions are words displayed on a television screen that explains the audio of a program to let viewers who are deaf or hard of hearing understand the dialogue and action of a program at the same time. Open captions are always on the screen and cannot be turned off.
Open Source: A movement in which software developers make their source code available to anyone for free collaboration. The Linux operating system, created by Linus Torvalds, was an early example, relying on an army of volunteers to keep it up to date.
OTT (Over-The-Top): refers to the delivery of audiovisual content streamed over the Internet without the involvement of an Internet service provider (ISP) in the control or distribution of the content. The ISP is neither responsible for, nor is able to control, the viewing abilities, copyrights, and/or other redistribution of the content, which arrives from a third party and is delivered to an end-user’s device. The ISP is only in the role of transporting IP packets. It's often referred to as "over-the-top” because these services ride on top of the service you already get. OTT services don't require any business or technology affiliations with the entity that controls or maintains the infrastructure through which the content is delivered to end-users.
OTT includes the distribution of linear programming and non-linear video-on-demand (VOD) and electronic sell-through (EST) content. Smartphones, tablets, computers, gaming consoles, DVD/Blu-ray Disc players, televisions, and set-top boxes/devices (e.g., Apple TV, Fire TV, Google Chromecast, and Roku.) with internet connectivity are able to access content via the internet from companies and services like Amazon Video, CBS All Access, HBO Now, Hulu, Netflix, and Sling TV.)
P2P (Peer-to-Peer) Networking: Unlike a network where all network clients make requests to one central server, a P2P network model makes the download requests to other clients. Once a user logs into a P2P network, the user is immediately both a client and a server simultaneously (though some systems permit "freeloading", wherein the server function is disabled). Users can download files from other users, and other users can download files from them. An example is BitTorent first implemented in 2001, wherein a single download may come from multiple servers, each server delivering portions of the file which are assembled as a single file on the user's device.
Perceptible Copyright Notice: A Copyright Notice that can be seen by the consumer at the first point of interaction (e.g. at the point of purchase, at the point of preparing to place a disc in a drive, or at the point of beginning to watch a movie). The manner of making perceptible will vary with the context in which the Perceptible Copyright Notice is required. For example, perceptible on the disc, cover or packaging (in the case of a copy sold or rented); perceptible when the work is performed (in the case of streaming, when performed publicly; in the case of digital delivery, when performed privately); or perceptible in a web browser display (when offered for sale, rental, streaming or download from a website).
Portable Media Player: A consumer electronics device that is capable of storing and playing digital media. Data is typically stored on a hard drive, microdrive, or flash memory. Sometimes referred to as a portable video player (PVP).
Primary Studio: The production entity with underlying distribution rights to a property in a specific market.
Primary Genre: A type or category of movie or television show (such as drama, comedy, musical, action/adventure, etc)
Pro Res/ Quicktime: Apple's post-production format offering uncompressed HD quality at SD file sizes. Use ProRes 422 when collaborating over an Xsan storage network or working on a portable computer in the field; when working with non-native camera formats; or to preserve maximum quality for composites and demanding color grading work.
Price Per Unit: The price charged by the Licensor for a single unit of a copyright (e.g. price per Reproduction/Download, price per Stream) associated with a given title.
PVD: Permanent Video Download. See EST
Ratings: A Rating is a code or classification given to a work to alert consumers whether particular attention should be given to the work's suitability for audience members below a particular age level. For purposes of this Glossary, any reference to a "Rating" should specify the rating system to which it refers. For example, "MPAA-PG" to refers the "PG" (Parental Guidance) rating given by the Classification and Ratings Administration of the Motion Picture Association of America .
Roles: Screen names of key characters in a movie or television show.
RSS (Really Simple Syndication): Format for storing online information to make it readable by many different kinds of software. Many blogs and web sites feature RSS feeds, constantly updated in a form that can be read by a newsreader or aggregator.
Run Time: The amount of time from the start of a film or of a television show, through the end including the run of credits.
SD (Standard Definition): Is the basic level of quality display and resolution for both analog and digital, of which the picture is 480 x 640 pixels, with interlaced scanning.
Series: A group of programs created or adapted for broadcast, webcast or podcast with a common series title, usually related to one another in subject or otherwise. Often, series appear once a week during a prescribed time slot; however, they may appear with more or less frequency. Series are usually created to be open-ended, not with a predetermined number of episodes . In a fiction series, the programs typically share the same characters and basic theme.
Silverlight: A web browser plug-in that provides support for rich internet applications such as animation, vector graphics and audio/video playback. Silverlight competes with companies such as Adobe Flash, Adobe Flex, Adobe AIR, Adobe Shockwave, JavaFX, and Apple QuickTime. Version 2.0 brought improved interactivity and support for .NET languages and development tools.
Social Network: An online and social community of people who share interests and activities or who are interested in exploring the interests or activities of others.
Stream: A single encrypted digital transmission of an audio or video file solely through the electronic medium and does not produce a fixed file embodying that can be rendered without a simultaneous active connection to the internet other than a temporary file created solely to render such contemporaneous performance as in the form of a data buffer or cache copy.
Studio ID #: Unique identifier assigned by an individual studio for internal tracking purposes.
Street Date: The date on which the Licensor first makes a title available to the public in a specific format. For physical media that cannot be made available to merchants at the same time, "Street Date" refers to the date at which the various merchants agree to make it available to their customers in order to ensure a level playing field, enable targeted promotions and avoid customer confusion as to availability.
Subscription: A business model in which the retail customer may obtain specified goods or services for only so long as a subscription is maintained (typically month to month).
SVOD (Subscription Video On Demand): For a fixed, recurring fee, subscribers may have unlimited streaming to a licensed catalog of content for the duration of their active subscription term. Subscription terms may be as short as one month (Hulu Plus, Netflix) or as long as one year (Amazon Prime).
Synopsis: A brief description of the contents of a particular work. The synopsis if most often provided by the publisher of the work for use in promotional materials by other merchants, but may also be prepared independently by any given merchant.
Talent: Key actors/actresses in a movie or television show.
Television Rating: Television Parental Guideline System Rating of a television show, established by the individual broadcast or cable network airing the program. Ratings are VY, TVY7, TVG, TVPG, TV14, and TVMA, and reflect the amount of violent or sexual content and language.
Trailers: Promotional clips of titles when prepared by or for the copyright owner in the title, and which may be separate copyrighted works. (Trailers do not include promotional clips offered as an actual short sample of the work to assist a customer in making selection.)
Transactional: An agreement between parties to exchange certain rights to content for money.
Transactional VOD: A digital rental of a program for a specified viewing period (such as 24 or 48 hours) for viewing by the consumer when the consumer wants to watch it.
Transcoding: A process that changes the video or audio features of a file, such as the resolution or bit rate, by changing portions of the audio/visual content but not by reconstructing the content (as would be in encoding ). Compressed-domain transcoding also maintains the format of the file.
Ultra High Definition: Unlike standard HDTV, Ultra HDTV is four times as wide and four times as high, producing an astonishing 7,680 × 4,320 pixel resolution. Ultra HDTV is 16 times the pixel resolution of standard HDTV. Sound quality is also significantly increased with Ultra HDTV. 24 channels of audio can be used with 24 speakers, producing a difference comparable to the Ultra HD video resolution.
Ultraviolet: An ecosystem for interoperable electronic content. It's a branded set of specifications and agreements along with a centralized rights clearinghouse that allows retailers to sell movies that play on UltraViolet-compatible players and services.
UMID (Universal Media ID): An item number unique among all assets to an individual digital asset
UPC: A barcode symbology uniquely assigned to an individual trade item.
Uploading: The transmission of a file from one computer system to a server, which results in a reproduction of the work to a second medium specified by the second computer system.
Visually Perceptible Copyright Notice: Notice which contains all the following three elements: (a) the symbol © (the letter C in a circle), or the word "Copyright," or the abbreviation "Copr."; (b) the year of first publication of the work; (c) and the name of the owner of copyright in the work, or an abbreviation by which the name can be recognized, or a generally known alternative designation of the owner.
VOD (Video On Demand): Content either streamed or downloaded to a device such as a computer or set-top box for viewing by the consumer when the consumer wants to watch it. This content may be owned by the consumer or may have been rented for a limited period or number of plays (transactional VOD).
Watermark: Technology used to embed information, including content usage rules, securely into a video or audio signals, designed to be imperceptible to the audience. Watermarks survive and "travel with" content as it is converted from digital to analog form or is re-digitized from analog. Since they are embedded within the actual content, watermarks are difficult to remove. However, watermarks do not in themselves protect content - protection is only achieved if devices and products are designed to inspect content for watermarks and to respond appropriately to the rules associated with that watermark.
Widget: A small downloadable application that resides on a computer's desktop or can be embedded on blogs, social networking profiles, personal start pages or other websites. Widgets can play audio or video tracks, conduct polls or quizzes, run slideshows or provide news o stock prices, or a multitude of other minor tasks.
Wiki: A collaboratively edited web page. The best-known example is wikipedia, an encyclopedia that anyone in the world can help to write or update. Wikis are frequently used to allow people to write a document together, or to share reference material that lets colleagues or even members of the public contribute content.
Window: A period of time during which a copyright owner exercises its right to do or to authorize one or more of its exclusive rights though one particular channel of dissemination and before authorizing the next channel of dissemination. For example, a theatrical first run window is the period during which a film is licensed for public performances in theaters and before it is distributed on DVD.
Windows Media: A group of technologies developed by Microsoft including Microsoft's Digital Rights Management tools,Windows Media Video encoding technology and Windows Media Audio encoding technology. These are proprietary standards similar to MPEG-4.
Windows Media DRM: A DRM system built into Microsoft's Windows Media Player software found on most Windows-based PCs as well as on many consumer electronics devices. It is widely used to provide secure Internet delivery of audio and audiovisual content to any device that has that enabled.
Wireless Application Protocol (WAP): is the open international standard for applications written for cell phones or other wireless devices including Blackberrys and PDAs. A WAP browser surfs sites written to the standard, just like an internet web browser does.
WMV (Windows Media Video): Microsoft's proprietary video encoding solutions.
Wrapper: The format for storing video, audio, and other possible data within a "container ".
XML (Extensible Markup Language): A general purpose standard for describing, or marking up, documents and data distributed on the web. XML allows authors to create customized tags that can help them efficiently achieve their goals.
