39、ulted from proprietary extensions of earlier HTML versions to fill identified gaps. HTML5 also defines and for the first time error handling procedures to deal with document processing errors to help circumvent minor but common syntactical mistakes. As part of the simplicity goal, HTML5 aims at oper
40、ating in a plugin-free environment by providing APIs to fulfil most of the plugin needs. Finally, HTML5 aims at simplifying the syntax to ease authoring of web applications. 4.1.2 New Tags HTML5 defines a set of new elements that are discussed in the following list: - Video: a standard way to embed
41、video content on a web page without using browser plugins. The playback controls are provided through Javascript. - Audio: a standard way to embed audio content on a web page without using browser plugins. - Canvas: a resolution-dependent bitmap canvas together with scripts that are used for renderi
42、ng graphs, game graphics, or other visual images on the fly. - Svg: HTML5 provides support for inline SVG fragments as well as a fallback mechanism for browsers that do not support SVG. - Article: specifies independent self-contained content. An article should make sense on its own and should be dis
43、tributable independently from the rest of the site. - Header: specifies a header for a document or section. This element should be used as a container for introductory content or set of navigational links. - Footer: defines a footer for a document or section. A footer element should contain informat
44、ion about its containing element. - Output: represents the result of a calculation. - Source: is used to specify multiple media resources for media elements such as video and audio. The source tag allows to specific alternative video/audio files, which the browser may choose from, based on its media
45、 type or codec support. - Time: defines either a time or a date in the Gregorian calendar, optionally with a time and time-zone. - Input/capture: although the tag is not new for HTML5, the capture attribute is. This allows for media capture and file upload 21. ETSI ETSI TR 126 907 V14.0.0 (2017-04)8
46、3GPP TR 26.907 version 14.0.0 Release 144.1.3 New HTML5 APIs 4.1.3.1 Introduction HTML5 can be considered as an umbrella set of specifications, that includes the markup language specification and additionally a wide range of APIs. The following sections briefly introduce the APIs that are currently
47、part of HTML5. Only specifications that have reached Candidate Recommendation status in the W3C are described. However, several specifications under development related to areas such as local media capture, peer-to-peer real time communications (WebRTC), sensors (proximity, gyroscope, etc.), rich au
48、dio processing, and technologies impacting mobile devices should be considered for any 3GPP presentation layer in the near future. 4.1.3.2 Canvas API The canvas API 2 defines a canvas element and a set of drawing operations. A canvas element creates a rectangular area on the page. Javascript is used
49、 to perform the drawing operations. 4.1.3.3 Cross-document messaging API HTML5 introduces an API 1 to enable safe communication between different parts of the document (e.g. different frames). Additionally, HTML5 introduces the security concept of origin. This is used to enable secure cross-referencing between documents that are located on the same origin, identified through a shared URL path. 4.1.3.4 Geolocation API The Geolocation API 3 allows the user to share their location with web applic
