BS EN 301549-2014 pdf download.Accessibility requirements suitable for public procurement of ICT products and services in Europe.
caption: synchroniied visual andior text alternative for both speech and non-speech audio information needed to understand the media content (after WCAG 2.0 (4J)
NOTE: This is also variously described using terms such as ‘suhtitles” or variants such as subtitles for the deaf and hard-of-hearing”.
dosed functionality: functionality that is limited by characteristics that prevent a user from attaching. installing or using assistive technology
content: information and sensory experience to he communicated to the user by means of software, including code or markup that defines the content’s stnicure. presentation, and interactions (after WCAG2ICI’ Ii.261)
NOTE: Content occurs in three places: web pages. documents and software. When content occurs in a web page or a document, a user agent is needed in order to communicate the content’s information and sensory experience to the user. When content occurs in software, a separate user agent is not needed in order to communicate the content’s information and sensory experience to the user the software itself performs that function,
context of use: users, tasks, equipment (hardware. software and materials), and the physical and social environments in which a product is used (from ISO 9241-Il Ii. l5J
document: logically distinct assembly of content (such as a file, set of files, or streamed media) that functions as a
single entity rather than a collection, that is not part of software and that does not include its own user agent. (after
WCAG2ICT Ii.261)
NOTE I: A document always requires a user agent to present its content to the user.
NOTE 2: Letters, e-mail messages, spreadsheets, hooks, pictures, presentations, and movies are examples of documents.
NOTE 3: Software configuration and storage files such as databases and virus definitions, as well as computer instruction files such as source code. batch/script files, and firmware, are examples of files that function as part of software and thus are not examples of documents. If and where software retrieves “information and sensory experience to be communicated to the user from such tiles, it is just another part of the content that occurs in software and is covered by WCAG2ICT like any other parts of the software. Where such files contain one or more embedded documents, the embedded documents remain documents under this definition.
NOTE 4: A collection of files tipped together into an archive, stored within a single virtual hard drive file, or stored in a single encrypted file system file, do not constitute a single document when so collected together. The software that archives/encrypts those files or manages the contents of the virtual hard drive does not function as a user agent for the individually collected files in that collection because ihat software is not providing a non-fully functioning presentation of tha content.
NOTE 5: Anything that can present its own content without involving a user agent, such as a self-playing book, is not a document but is software.
mechanically operable part: operable part that has a mechanical interface to activate, deactivate, or adjust the ICT
NOTE: Examples of mechanically operable parts include scanner covers, notebook docking stations and lids as well as physical switches and latches.
mechanism for pd. ate listening: auditory output designed so that only the current user can receive the sound
NOTE: Personal headsets, directional speakers and audio hoods are examples of mechanisms for private listening.
non-text content: content that is not a sequence of characters that can be programmatically determined or where the sequence is not expressing something in human language (after WCAG 2.0 141)
non-web document: chxumeni that is not a web page, not embedded in web pages nor used in the rendering or functioning of the page
non-web soflware: software that is not a web page. not embedded in web pages nor used in the rendering or functioning of the page
operable part: component of ICT used to activate. deactivate, or adjust the ICJ’
platform soft’.’.arc: collection of software components that runs on an underlying software or hardware layer. and thai provides a set of software services to other software components that allows those applications to be isolated from the underlying software or hardware layer (after ISOIIF.C 13066-I Ii.l9D
NOTE: A particular software component might play the role of a platform in some situations and a client in others.
prorammaticalI’. determinable: able to be read by software from developer-supplied data in a way that other software, including assistive technologies., can extract and present this infirmaiion to users in different modalities
NOTE: WCAG 2.0 uses dciermincd” where this definition uses “able to be read” (to avoid ambiguity with the word “determined”).
real-tlnn text: form of a text conversation in point to point situations or in multipoini conkreneing where the text being entered is sent in such a way that the communication is perceived by the user as being continuous
satisfies a success criterion: the success criterion does not evaluate to “false” when applied to the l(’ (after WCAG 2.0 141
terminal: combination of hardware andJor software with which the end user directly interacts and that provides the user interface
NOTE I: The hardware may consist of more than one device working together e.g. a mobile device and a computer.
NOTE 2: For some systems. the software that provides the user interface may reside on more than one device such as a telephone and a server.
user agent: software that retrieves and presents content tbr users (after WCAG 2.0 (41).BS EN 301549-2014 pdf download.
