Introduction ITU-TFG IPTV Was the end of 2007. WG6 the contents of which group more, including middleware, codecs, multimedia application platform, etc; then, ITU-TSG16 group established a new "Question (problem): IPTV multimedia application platforms and end systems," Study Group to prepare the next SG16 group meeting once a formal recommendation on the given document. Currently there are standards for a wide variety of multimedia application platform is basically divided into the definition of multimedia application platform standards and procedural standards for multimedia application platform, function differently. This article explains what these two types of platforms, including specific criteria, and the development of multimedia application platform in China put forward their own views. Defining application platform Defining application platform is a framework used in this framework, the markup language (eg HTML), with or without scripting language (such as ECMAScript) can run applications written in. Here are some definitions of application platform. 1, scene of the binary format (BIFS) BIFS [ISO/IEC14496-11] is an ISO standard scene description language, as part of MPEG-4, is used effectively to show the dynamic and interactive applications, including two-dimensional / three-dimensional graphics, images, text and Audio and Video Part. This show includes elements of different scenes of time and space, the description of user interaction and activities. 2, Broadcasting Markup Language (BML) BML [ARIBSTD-B24] [ITU-TJ.201] is a description of the application of multimedia broadcasting standard, standardized by the Japan Broadcasting Association business. BML by the XHTML, CSS, DOM and ECMAScript composition. BML has been amended to include additional features such as an increase on the receiving end of digital storage, an increase of terrestrial digital broadcasting for mobile reception. Terrestrial Integrated Services Digital Broadcasting (ISDB-T) was the first multimedia coding standard based on multimedia and hypermedia information coding Expert Group (MHEG) specification. And since since March 1999, ARIB Association began MHEG multimedia encoding mechanism based on XML specification. This is conducive to the development of XML application language can BML browser-based XML file to display. ARIB data broadcasting system standards promulgated in October 1999. The same as the MHEG, BML application can be multiple media formats, structural elements, the event - action relationship, navigation, user interaction functions of synchronization and space-time correlation. BML is defined using ECMAScript to broadcast additional API and objects. 3, the Consumer Electronics Association (CEA) CEA-2014 is a remote user interface specification, which allows the user interface displayed on the remote device. It is based on an existing Web presentation technology, using W3C mark, XHTML1, ECMA-262, CSSTV framework and DOM2 electronic consumer technology show in the browser. CEA-2014 defines a mechanism that allows a user interface on the remote display, and are devices or control points, rather than being controlled by the logic of the host. Basic device operation is based on the Universal Plug and Play Device Architecture version 1.0 (for home networking and Plug and Play Plug and Play devices developed). Standard also allows third-party Internet service to families in the Plug and Play devices on the remote display, covering TV, mobile phones and mobile devices in the user interface. The main content of CEA-2014 is CE-HTML framework, which uses XHTML content to define user interface, can show different resolutions and screen sizes, including HD Screen and mobile phone screen. 4, Cascading Style Sheets
