In the computer the accessibility the multimedia plays vital role SMIL is used for multimedia presentations that integrates streaming audio and video with images, the presentations that are by SMIL are described as text files the user can create or edit a SMIL presentation by using a text editors, the documents of SMIL are specified by URLS, media elements can be files such as text files, JPEG images quick time movies or live streams.

The Synchronized Multimedia Integration Language (SMIL, pronounced "smile") enables simple authoring of interactive audiovisual presentations. SMIL is typically used for multimedia presentations that can integrate streaming audio and video with images, text or any other media type.
SMIL presentations are described by text files. You can create or edit a SMIL presentation using a text editor, and you can automatically generate a SMIL document using any script language that creates text files. A SMIL document specifies what media elements to present
Writing SMIL can in some ways make accessibility seem more difficult. For questions, this web page is helpful. Here is a bit on what they have to say about text timing:
"27.4.5.1. Time containers
Media elements are placed in special time container elements (<par>, <seq>, and <excl>) that define how the media should be played. The <par> element (short for "parallel") defines a group of elements that play at the same time. The <seq> element defines a sequence of elements that play one after another, in the order in
"Although MPEG (Moving Picture Experts Group) also looks at content and coding, SMIL is more web-centric unlike MPEG, which is more media centric and involves more than just content and coding. A close comparison would be D-HTML (dynamic hypertext markup language). However, D-HTML uses scripted definitions of local behaviours, without a notion of the presentation's context. Actions such as timed events are therefore difficult to co-ordinate.
Then there are W3C technologies such as cascading style sheets (CSS) which are compatible with SMIL, which
