MHEG-5
The MHEG-IC gives access to streamed on-demand video content in addition to traditional text and graphics as well as the ability to support secure transactions.MHEG-5 is an object-based declarative programming language which can be used to describe a presentation of text, images and video.Each Scene lists the items of text and graphics to be presented and can contain blocks of procedural code which are executed in response to one of a predefined set of events such as keys being pressed, timers firing or content being successfully loaded into memory.MHEG is also used on Freesat for its programming guide in addition to the DVB EIT, as opposed to the OpenTV platform used on Sky.In New Zealand, the same profile as in UK is used, with minor additions for the Maori language and its use of the guide key on certified Freeview receivers.
