MHEG-5

MHEG stands for Multimedia and Hypermedia information coding Expert Group, which is a working group of ISO. In addition, the standard created by this group with the official name Coding of multimedia and hypermedia information, and the number ISO / IEC 13522 is abbreviated with the aforementioned acronym.

This standard defines a format for multimedia documents in executable form, so that devices that support MHEG, can display such a document, similar to a browser, the HTML is. However MHEG provides the representation of hypermedia content including information on time synchronization in order to define, as in the presentation of document content such as video and audio from different sources with each other over time in relation. Main focus, however, lies next to the broad support of multimedia objects in the possibility of interactivity of the human observer with the content.

Motivation for this standard, which was originally published in 1997 by the ISO, was the lack of a standardized document description language with multimedia relevant skills. Since such a format is required in particular for the exchange of information with interactive television and at that time already in use proprietary solutions should be replaced, several organizations active and developed standards such as MHP also, which is used among others in Germany for the DVB were.

The script language that is defined by the MHEG- 5 above version of the standard, is used in the UK by the BBC for transmission in digital television. According to estimates of the British Parliament are 5 million MHEG -5 -compatible set- top boxes in the United Kingdom in operation.

In addition to home shopping, video on demand and presentation of the internet on the TV, MHEG is also about much more dependent interaction of ligand applications to be able, such as games.
