MHEG-5 Profiles

TeletextMHEG-5 profiles form the framework specification for the creation of MHEG-5-based technology and the deployment of MHEG-5-based services on a given platform. Profiles define various mandatory and optional features required to successfully deploy interactive services. This ensures that the standard is maintained and developed in unison.

Features specified within a typical MHEG-5 profile include:

  • the user experience
  • MHEG-5 engine presentation/graphics models
  • fonts and language character sets
  • extensions/modifications to the MHEG specification
  • receiver requirements
  • return channel mechanisms
  • object carousel profile
  • application authoring rules and guidelines

The profile forms the basis for specification and development of conformance test suites leading to better end-to-end interoperability for all stakeholders.

As custodians of the UK Profile, the UK Digital TV Group (DTG) with its stakeholder members consisting of manufacturers, broadcasters and technology providers, plays a key role in driving the specification and development of new requirements for MHEG-5 based products and services.

With the latest UK Profile version 1.06, the Digital Television Group (via DTG Testing) has developed a strong conformance test suite (of over 350 tests) ensuring interoperability for receiver manufacturers, broadcasters and content creators.
