MHEG-5

MHEG-5 (Multimedia & Hypermedia Expert Group), is a licence-free and public standard for interactive TV middleware that is used both to send and receive interactive TV signals.
MHEG-5 is used to provide interactive services for digital television such as the BBC’s red button service. The full specification of how MHEG-5 is used in the context of the UK Freeview platform is the UK Profile of MHEG-5. MHEG is also used on Freesat for its programming guide, as opposed to the OpenTV platform used on Sky.

MHEG-5 is an object-based declarative programming language which can be used to describe a presentation of text, images and video. An MHEG-5 application consists of a number of Scenes which the user of the application can move between. 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.
These blocks of code consist of elementary actions which can perform operations such as changing the text displayed by a text object, or starting a video clip playing.

MHEG-5 specifies a hierarchy of classes that are available to the application author. Unlike in object oriented languages, it is not possible for new classes to be defined. The standard defines two representations of MHEG applications, one of which is textual and the other is represented in ASN.1. Applications are normally written in the textual notation and then encoded into ASN.1 for interpretation by the MHEG engine. MHEG-5 is suited to programming interactive kiosks and interactive television services.
