Hypertext


Notes:


MHP devotes 110 pages of the standard to hypertext or "super teletext" based on web standards. The section is misleadingly entitled "DVB-HTML", when it is XHTML plus a set of style and scripting standards (CSS, DOM and ECMAScript). DVB-HTML is not required if only the Enhanced Broadcast Profile of MHP is implemented and is described as having a supplementary role "alongside broadcast". However, it is difficult to envisage practical applications which do not use DVB-HTML. The MHP specification provides for integration of DVB-HTML applications, with: signalling, transportation and content. MHP's DVB-HTML is described as a subset of World Wide Web standards, but as with WAP (discussed later) may be inconsistent with the current direction of web development. Not all formally adopted World Wide Web standards are necessarily taken up by the Internet community and not all features are well supported.
