40、PP TR 26.907 version 15.0.0 Release 154 Introduction 4.1 HTML5 4.1.1 Introduction HTML5 was specified with the target of creating convergence among a wide range of interoperable browsers, which resulted from proprietary extensions of earlier HTML versions to fill identified gaps. HTML5 also defines
41、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 operating in a plugin-free environment by providing APIs to fulfil most of the plugin needs. Finally, HTML5
42、 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 video content on a web page without using browser plugins. The playback controls are provided through J
43、avascript. - 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 rendering graphs, game graphics, or other visual images on the fly. - Svg: HTML5 provides support for inline S
44、VG 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 distributable independently from the rest of the site. - Header: specifies a header for a document or sect
45、ion. 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 information about its containing element. - Output: represents the result of a calculation. - Source: is used t
46、o 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 type or codec support. - Time: defines either a time or a date in the Gregorian calendar, optionally w
47、ith 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 V15.0.0 (2018-07)83GPP TR 26.907 version 15.0.0 Release 154.1.3 New HTML5 APIs 4.1.3.1 Introduction HTML5 can be consider
48、ed 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 part of HTML5. Only specifications that have reached Candidate Recommendation status in the W3C are des
49、cribed. 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 audio 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 to pe
